Capacitor discharge ignition ( CDI ) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors , motorcycles , lawn mowers , chainsaws , small engines, gas turbine -powered aircraft , and some cars . It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making the ignition system more suitable for high engine speeds (for small engines, racing engines and rotary engines). The capacitive-discharge ignition uses capacitor to discharge current to the ignition coil to fire the spark plugs .
93-471: Saab Direct Ignition is a capacitor discharge ignition developed by Saab Automobile , then known as Saab-Scania, and Mecel AB during the 1980s. It was first shown in 1985 and put into series production in the Saab 9000 in 1988. One of the first instances of using the system was for a Formula Three racing engine (on B202 basis) developed with the help of engine builder John Nicholson , first shown in
186-582: A 60 Minutes interview with Steve Kroft , Sergio Marchionne responded "just to rectify the record I paid back the loans at 19.7% Interest. I don't think I committed to do to a commercial on top of that" and characterized the Republican reaction as "unnecessary and out of place". In 2014, Chrysler started using a new slogan, "America's Import" in ads introducing their all-new 2015 Chrysler 200 , targeting foreign automakers from Germany to Japan with such ads (German performance and Japanese quality), and at
279-401: A $ 50 million stock offering. $ 180 million was to come from concessions from dealers and suppliers. Also in 1978, Iacocca offloaded the ailing European operation to PSA Peugeot Citroën for a nominal $ 1, taking with it the group's substantial losses and debts which had been dragging the rest of the business down. After a period of plant closures and salary cuts agreed to by both management and
372-465: A 19.9% stake. The economic collapse during the Financial crisis of 2007–2008 pushed the company to the brink. On April 30, 2009, the automaker filed for Chapter 11 bankruptcy protection to be able to operate as a going concern, while renegotiating its debt structure and other obligations, which resulted in the corporation defaulting on over $ 4 billion in secured debts. The U.S. government described
465-590: A March 27 mediation to try to settle the lawsuit over the clothing company's use of "Imported from Detroit" slogan. Pure Detroit stated that Chrysler has made false claims about the origins of three vehicles - Chrysler 200, Chrysler 300 and Chrysler Town & Country - none of which are built in Detroit. Pure Detroit also said that Chrysler's Imported From Detroit merchandise is not being made in Detroit. In 2012 Chrysler and Pure Detroit came to an undisclosed settlement. Chrysler's Jefferson North Assembly , which makes
558-609: A bailout from the U.S. government through the Troubled Asset Relief Program . On June 10, 2009, Chrysler emerged from the bankruptcy proceedings with the United Auto Workers pension fund, Fiat S.p.A. , and the U.S. and Canadian governments as principal owners. The bankruptcy resulted in Chrysler defaulting on over $ 4 billion in debts. In May 2011, Chrysler finished repaying its obligations to
651-473: A capacitor and then discharged the capacitor through the ignition coil primary winding. An excerpt from the 'Motorway' Jan 11 1906, describes its use on Ford six cylinder cars: 'The efficiency of the Ford Magneto is shown by the fact that the instant it is switched in the car will pick up speed and, without changing the position of the ignition control lever, will run at least ten miles an hour faster.' It
744-777: A detailed Capacitor-discharge Ignition system as an electronic hobby build project by R.M. Marston. The circuit of this system was similar to the Winterburn patent in that it used a push-pull converted switch mode oscillator for energy transfer to a store - discharge capacitor and conventional contact breakers to initiate a thyristor triggering discharge of the charged CD capacitor. It was stated to offer several advantages over conventional ignition. Among which: better combustion, easy starting even under subzero conditions, immunity to contactor (points) bounce and 2% - 5% fuel economy. Subsequent letters to Wireless World ( March & May 1970), with Mr. Marston's replies, further discussed aspects of
837-749: A drawing, a mechanical means to accomplish its purpose. Originally invented for Henry Fords six cylinder racer in 1905, the first production use of a CDI system was put into use in 1906 as standard equipment with the Ford Model K. The Model K utilized dual ignition systems, one of which was the Holley-Huff Magneto, or Huff System, manufactured by the Holley Brothers Company. It was designed by Edward S. Huff with US patent #882003 filed July 1, 1905 and assigned to Henry Ford. The system used an engine driven DC generator that charged
930-450: A minimum of 5% increase in horsepower with the system, with 10% the norm. One example, a Ford Falcon , had an increase in horsepower of 17%. Spark plug lifespan was increased to at least 50,000 miles and points lifespan was greatly extended from 8,000 miles to at least 60,000 miles. Points lifespan became a factor of rubbing block (cam follower) wear and the life cycle of the spring with some lasting almost 100,000 miles. The Hyland unit
1023-461: A new FCA logo were announced. The most challenging launch for this new company came immediately in January 2014 with a completely redesigned Chrysler 200 . The vehicle's creation is from the completely integrated company, FCA, executing from a global compact-wide platform. On December 16, 2014, Chrysler Group LLC announced a name change to FCA US LLC. On January 12, 2017, FCA shares traded at

It began an engineering partnership with Mitsubishi Motors , and began selling Mitsubishi vehicles branded as Dodge and Plymouth in North America. On the verge of bankruptcy in the late 1970s, it was saved by $ 1.5 billion in loan guarantees from
1209-406: A production car. The system puts a low voltage over the spark plugs when they are not fired to measure ionization in the cylinders. The ionic current measurement is used to replace the ordinary knock sensor and misfire measurement function. The spark plugs are directly coupled to the "DIC" (or "IDM") which houses the ignition coils and electronics that measure cylinder ionization for use by
1302-569: A result. This early German system used a rotary DC converter along with fragile tube circuitry, and was not suited to life in a fighter aircraft. Failures occurred within only a few hours. The quest for a reliable electronic means of producing a CD ignition began in earnest during the 1950s. In the mid-1950s, the Engineering Research Institute of the University of Michigan in cooperation with Chrysler Corporation in
1395-546: A short spark duration limited to about 50-600 μs. The fast voltage rise makes CDI systems insensitive to shunt resistance, but the limited spark duration can for some applications be too short to provide reliable ignition. The insensitivity to shunt resistance and the ability to fire multiple sparks can provide improved cold starting ability. Since the CDI system provides only a reduced duration spark, it's also possible to combine this ignition system with ionization measurement. This
1488-404: A strong DC current pulse as the flywheel magnet moved over it. (If the engine was rotated while examining the wave-form output of the coil with an oscilloscope, it would appear to be AC. However, since the charge-time of the coil corresponds to much less than a full revolution of the crank, the coil really 'sees' only DC current for charging the external ignition coil.) This DC current flowed through
1581-401: A strong likelihood of winning its case. Therefore, Pure Detroit's owner, Detroit retailer Moda Group LLC, can continue selling its "Imported from Detroit" products. Tarnow also noted that Chrysler does not have a trademark on "Imported from Detroit" and rejected the automaker's argument that trademark law is not applicable to the case. In March 2012, Chrysler Group LLC and Pure Detroit agreed to
1674-595: A subsidiary of Stellantis , the company formed from the 2021 merger of FCA and PSA Group (Peugeot Société Anonyme). After founding the company, Walter Chrysler used the General Motors brand diversification and hierarchy strategy that he had become familiar with when he worked in the Buick division at General Motors. He then acquired Fargo Trucks and the Dodge Brothers Company , and created
1767-536: A thyratron CD ignition, model Tung-Sol EI-4 in 1962, but it was expensive. Despite the failings of thyratron CD ignitions, the improved ignition that they gave made them a worthwhile addition for some drivers. For the Wankel powered NSU Spider of 1964, Bosch resurrected its thyratron method for a CD ignition and used this up until at least 1966. It suffered the same reliability problems as the Tung-Sol EI-4. It
1860-408: A wire to an ignition coil mounted outside of the engine. The points sometimes were under the flywheel for two-stroke engines, and commonly on the camshaft for four-stroke engines. This system worked like all Kettering (points/coil) ignition systems: the opening points trigger the collapse of the magnetic field in the ignition coil, producing a high voltage pulse which flows through the spark plug wire to

As a simple example, a typical ignition coil may have a secondary winding resistance of 4000 ohms and a secondary current of 400 milliamperes. Once a spark has struck, the voltage across the spark gap in a running engine drops to a relatively low value, in the order of 1500-2000 volts. This, combined with
2232-500: Is the smallest of the "Big Three" U.S. automakers (Stellantis North America, Ford Motor Company , and General Motors ). In 2020, FCA US sold just over 1.8 million vehicles. Chrysler was the world's 11th largest vehicle manufacturer as ranked by OICA in 2012. Total Chrysler vehicle production was about 2.37 million that year. The company has since become a wholly-owned subsidiary and no longer reports global sales. In 2007, Chrysler began to offer vehicle lifetime powertrain warranty for
2325-528: The Chrysler Voyager in Austria for European markets in 1992. In 1998, Chrysler and its subsidiaries entered into a partnership dubbed a "merger of equals" with German-based Daimler-Benz AG, creating the combined entity DaimlerChrysler AG . To the surprise of many stockholders, Daimler acquired Chrysler in a stock swap before Chrysler CEO Bob Eaton retired. Under DaimlerChrysler, the company
2418-583: The Jeep/Eagle division as a "specialty" arm to market products distinctly different from the K-car-based products with the Eagle cars targeting import buyers. Former AMC dealers sold Jeep vehicles and various new Eagle models, as well as Chrysler products, strengthening the automaker's retail distribution system. Eurostar , a joint venture between Chrysler and Steyr-Daimler-Puch , began producing
2511-492: The Plymouth and DeSoto brands in 1928. Facing postwar declines in market share, productivity, and profitability, as GM and Ford were growing, Chrysler borrowed $ 250 million in 1954 from Prudential Insurance to pay for expansion and updated car designs. Chrysler expanded into Europe by taking control of French, British, and Spanish auto companies in the 1960s; Chrysler Europe was sold in 1978 to PSA Peugeot Citroën for
2604-513: The Super Bowl . Its two-minute February 5, 2012 Super Bowl XLVI advertisement was titled "Halftime in America". The ad drew criticism from several leading U.S. conservatives , who suggested that its messaging implied that President Barack Obama deserved a second term and, as such, was political payback for Obama's support for the federal bailout of the company. Asked about the criticism in
2697-464: The Trionic engine management system. Capacitor discharge ignition The history of the capacitor discharge ignition system can be traced back to the 1890s when it is believed that Nikola Tesla was the first to propose such an ignition system. In U.S. patent 609,250 first filed February 17, 1897, Tesla writes 'Any suitable moving portion of the apparatus is caused to mechanically control
2790-426: The alternating current produced by the alternator . The AC-CDI system is the most basic CDI system which is widely used in small engines. The DC-CDI module is powered by the battery, and therefore an additional DC/AC inverter circuit is included in the CDI module to raise the 12 V DC to 400-600 V DC, making the CDI module slightly larger. However, vehicles that use DC-CDI systems have more precise ignition timing and

2976-535: The 1950s using thyratrons . However, thyratrons were unsuitable for use in automobiles for two reasons. They required a warm-up period which was a nuisance, and were vulnerable to vibration which drastically reduced their service life. In an automotive application, the thyratron CD ignition would fail in weeks or months. The unreliability of those early thyratron CD ignitions made them unsuitable for mass production despite providing short term benefits. One company at least, Tung-Sol (a manufacturer of vacuum tubes) marketed
3069-779: The 47% ownership of AMC that was held by Renault . The remaining outstanding shares of AMC were bought on the NYSE by August 5, 1987, making the deal valued somewhere between US$ 1.7 billion and US$ 2 billion, depending on how costs were counted. Chrysler CEO Lee Iacocca wanted the Jeep brand, particularly the Jeep Grand Cherokee (ZJ) that was under development, the new world-class manufacturing plant in Bramalea, Ontario , and AMC's engineering and management talent that became critical for Chrysler's future success. Chrysler established
3162-581: The Big 3 US automakers, Chrysler lacked the financial resources to meet all of these challenges. In 1976, with the demise of the reliable Dart/Valiant, quality control declined. Their replacements, the Dodge Aspen and Plymouth Volare , were comfortable and had good roadability, but owners soon experienced major reliability problems which crept into other models as well. Engines failed and/or did not run well, and premature rust plagued bodies. In 1978, Lee Iacocca
3255-459: The CDI system can store for the generation of a spark is dependent on the voltage and capacitance of the capacitors used, but usually it is around 50 mJ , or more. The standard points/coil/distributor ignition, more properly called the inductive discharge ignition system or Kettering ignition system , produces 25mJ at low speed and drops off quickly as speed increases. One factor often not taken into consideration when discussing CDI spark energy
3348-578: The Chalmers automobile was ended. In January 1924, Walter Chrysler launched the well-received Chrysler automobile. The Chrysler Six was designed to provide customers with an advanced, well-engineered car, at an affordable price. Elements of this car are traceable to a prototype which had been under development at Willys during Chrysler's tenure The original 1924 Chrysler included a carburetor air filter, high compression engine, full pressure lubrication, and an oil filter, features absent from most autos at
3441-692: The Chrysler Corporation began dividing its vehicle offerings by price class and function. The Plymouth brand was introduced at the low-priced end of the market (created essentially by once again reworking and rebadging the Chrysler Series 50 four-cylinder model). At the same time, the DeSoto brand was introduced in the medium-price field. Also in 1928, Chrysler bought the Dodge Brothers automobile and truck company and continued

In March 2011, Chrysler Group LLC filed a lawsuit against Moda Group LLC (owner of Pure Detroit clothing retailer) for copying and selling merchandise with the "Imported from Detroit" slogan. Chrysler claimed it had notified defendant of its pending trademark application February 14, but the defendant argued Chrysler had not secured a trademark for the "Imported From Detroit" phrase. On June 18, 2011, U.S. District Judge Arthur Tarnow ruled that Chrysler's request did not show that it would suffer irreparable harm or that it had
3999-575: The New York Stock Exchange lost value after the EPA accused FCA US of using emissions cheating software to evade diesel-emissions tests, however the company countered the accusations, and the chairman and CEO Sergio Marchionne sternly rejected them. The following day, shares rose as investors played down the effect of the accusations. Analysts gave estimates of potential fines from several hundred million dollars to $ 4 billion, although
4092-685: The Rambler ran fine in warm weather, but suffered hard starting in cooler temperatures and AMC decided not to use this EFI system on its 1957 Rambler Rebel production cars that were sold to the public. Chrysler also used the Bendix "Electrojector" fuel injection system and only around 35 vehicles were built with this option, on its 1958 production-built car models. Owners of EFI Chryslers were so dissatisfied that all but one were retrofitted with carburetors (while that one has been completely restored, with original EFI electronic problems resolved). The Valiant
4185-506: The SCR (thyristor) that resulted in a series of weak, untimed sparks that caused extreme misfiring. There were two possible solutions to the problem. The first would be to develop another means of triggering the discharge of the capacitor to one discharge per power stroke by replacing the points with something else. This could be done magnetically or optically, but that would necessitate more electronics and an expensive distributor. The other option
4278-491: The U.S. government five years early, although the cost to the American taxpayer was $ 1.3 billion. Over the next few years, Fiat S.p.A. gradually acquired the other parties' shares. In January 2014, Fiat acquired the rest of Chrysler from the United Auto Workers retiree health trust, making Chrysler Group a subsidiary of Fiat S.p.A. In May 2014, Fiat Chrysler Automobiles was established by merging Fiat S.p.A. into
4371-550: The U.S. government. New CEO Lee Iacocca was credited with returning the company to profitability in the 1980s. In 1985, Diamond-Star Motors was created, further expanding the Chrysler-Mitsubishi relationship. In 1987, Chrysler acquired American Motors Corporation (AMC), which brought the profitable Jeep , as well as the newly formed Eagle , brands under the Chrysler umbrella. In 1998, Chrysler merged with German automaker Daimler-Benz to form DaimlerChrysler AG ;

Namely; a fast voltage rise time to fire fouled or wet spark plugs , high energy throughout the RPM range resulting in better starting, more power and economy, and lower emissions . A few engineers, scientists, and hobbyists had built CD ignitions throughout
4743-699: The auto unions, the loans were repaid with interest in 1983. In November 1983, the Dodge Caravan/Plymouth Voyager was introduced, establishing the minivan as a major category, and initiating Chrysler's return to stability. In 1985, Diamond-Star Motors was created, further expanding the Chrysler-Mitsubishi relationship. In 1985, Chrysler entered an agreement with American Motors Corporation to produce Chrysler M platform rear-drive, as well as Dodge Omnis front wheel drive cars, in AMC's Kenosha, Wisconsin , plant. In 1987, Chrysler acquired

#17327974070324836-403: The capacitor, allowing the capacitor to discharge its output to the ignition coil before reaching the spark plug. A typical CDI module consists of a small transformer , a charging circuit, a triggering circuit and a main capacitor . First, the system voltage is raised to 250 to 600 volts by a power supply inside the CDI module. Then, the electric current flows to the charging circuit and charges
4929-496: The capacitor. The rectifier inside the charging circuit prevents capacitor discharge before the moment of ignition. When the triggering circuit receives the triggering signal, the triggering circuit stops the operation of the charging circuit, allowing the capacitor to discharge its output rapidly to the low inductance ignition coil. In a CD ignition, the ignition coil acts as a pulse transformer rather than an energy storage medium as it does in an inductive system. The voltage output to

5115-787: The company's action as a "prepackaged surgical bankruptcy". On June 10, 2009, substantially all of Chrysler's assets were sold to "New Chrysler", organized as Chrysler Group LLC. The federal government provided support for the deal with US$ 8 billion in financing at nearly 21%. Under CEO Sergio Marchionne , "World Class Manufacturing" or WCM, a system of thorough manufacturing quality, was introduced and several products were re-launched with quality and luxury. The Ram, Jeep, Dodge, SRT, and Chrysler divisions were separated to focus on their own identity and brand, and 11 major model refreshes occurred in 21 months. The PT Cruiser , Nitro , Liberty and Caliber models (created during DCX) were discontinued. On May 24, 2011, Chrysler repaid its $ 7.6 billion loans to

As a result of the merger between FCA and PSA , on 17 January 2021 it became a subsidiary of the Stellantis Group . The Chrysler company was founded by Walter Chrysler on June 6, 1925, when the Maxwell Motor Company (est. 1904) was re-organized into
5394-726: The design and build. In July 1971 Mr. A.P. Harris, undergraduate of the City University London made a detailed electrical engineering analysis of the Marston design as well as automotive engine measurement trials to verify fuel economy. These confirmed the benefits of the CD ignition system. However, he found that the core ingredient of the CD design rested on careful hand winding of the switch mode transformer and appropriate selection of oscillator transistors and choice of oscillator frequency. For various reasons, probably mostly cost,

#17327974070325766-408: The engine can be started more easily when cold. Not all small engine ignition systems are CDI. Some engines like older Briggs and Stratton use magneto ignition. The entire ignition system, coil and points, are under the magnetized flywheel. Another sort of ignition system commonly used on small off-road motorcycles in the 1960s and 1970s was called Energy Transfer. A coil under the flywheel generated
5859-436: The fact that the coil secondary current of 400 milliamperes loses approximately 1600 volts through the 4000 ohm secondary resistance means that fully 50% of the energy is lost in heating the coil secondary. Actual measurements show the real world efficiency to be only 35 to 38% when coil primary winding losses are included. Most CDI modules are generally of two types: The AC-CDI module obtains its electricity source solely from

On September 28, 1957, Chrysler announced the first production electronic fuel injection (EFI), as an option on some of its new 1958 car models (Chrysler 300D, Dodge D500, DeSoto Adventurer, Plymouth Fury). The first attempt to use this system was by American Motors on the 1957 Rambler Rebel . Bendix Corporation 's Electrojector used a transistor computer brain modulator box, but teething problems on pre-production cars meant very few cars were made. The EFI system in

The deal covered owner or lessee in U.S., Puerto Rico, and the Virgin Islands, for 2009 model year vehicles, and 2006, 2007, and 2008 model year vehicles purchased on or after July 26, 2007. Covered vehicles excluded SRT models, Diesel vehicles, Sprinter models, Ram Chassis Cab, Hybrid System components (including transmission), and certain fleet vehicles. The warranty
6138-623: The likelihood of a hefty fine was low. Senior United States Senator Bill Nelson urged the FTC to look into possible deceptive marketing of the company's diesel-powered SUVs. Shares dropped 2.2% after the announcement. FCA US would in 2022, plead guilty to a criminal charge of conspiring to defraud the US, to wire fraud, and to violate the Clean Air Act. On July 21, 2018, Sergio Marchionne stepped down as chairman and CEO for health reasons, and

In the standard system with points , distributor , ignition coil , ignition (Kettering system) points bounce prevents the coil from saturating fully as RPM increases resulting in a weak spark, thus limiting high speed potential. In a CD ignition, at least those early attempts, the points bounce created unwanted trigger pulses to

Most ignition systems used in cars are inductive discharge ignition (IDI) systems, which are solely relying on
6510-445: The merger proved contentious with investors. As a result, Chrysler was sold to Cerberus Capital Management and renamed Chrysler LLC in 2007. Like the other Big Three automobile manufacturers, Chrysler was impacted by the automotive industry crisis of 2008–2010 . The company remained in business through a combination of negotiations with creditors, filing for Chapter 11 bankruptcy reorganization on April 30, 2009, and participating in
6603-408: The mobile network of AT&T , providing the car with its own IP address. Internet connectivity using any Chrysler, Dodge, Jeep or Ram vehicle, via a Wi-Fi "hot-spot", is also available via Uconnect Web . According to Chrysler LLC, the hotspot range extends approximately 100 feet (30 m) from the vehicle in all directions, and combines both Wi-Fi and Sprint's 3G cellular connectivity. Uconnect
6696-636: The rejuvenation of the entire product lineup, which included the new, redesigned, and repackaged 2011 model year 200 sedans and 200 convertibles, the Chrysler 300 sedan, and the Chrysler Town & Country minivan. As part of the campaign, Chrysler sold a line of clothing items featuring the Monument to Joe Louis , with proceeds being funneled to Detroit-area charities, including the Boys and Girls Clubs of Southeast Michigan, Habitat for Humanity Detroit and
6789-487: The spark plug. Some electronic ignition systems exist that are not CDI. These systems use a transistor to switch the charging current to the coil off and on at the appropriate times. This eliminates the problem of burned and worn points, and provides a hotter spark because of the faster voltage rise and collapse time in the ignition coil. A CDI system has a short charging time, a fast voltage rise (between 3 ~ 10 kV/μs) compared to typical inductive systems (300 ~ 500 V/μs) and
6882-411: The spark plugs is highly dependent on the design of the CD ignition. Voltages exceeding the insulation capabilities of existing ignition components can lead to early failure of those components. Most CD ignitions are made to give very high output voltages but this is not always beneficial. When there is no triggering signal the charging circuit is re-connected to charge the capacitor. The amount of energy
6975-535: The spring of 1985. The system has been revised several times over the years. The ignition system together with the ignition coils form a single transformer oil filled cassette (or two cassettes in the case of a V6 engine) which is placed directly on the spark plugs , without the need for a distributor . It was later implemented with the Saab Trionic Engine Management Systems as one of the first ion sensing ignition system on
7068-497: The successful Dodge line of automobiles and Fargo range of trucks. By the mid-1930s, the DeSoto and Dodge divisions would trade places in the corporate hierarchy. The Imperial name had been used since 1926 but was never a separate make, just the top-of-the-line Chrysler. However, in 1955, the company decided to offer it as its own make/brand and division to better compete with its rivals, Lincoln and Cadillac . This addition changed
7161-457: The summer of 1963 when Hyland exposed the design to a US company in an effort to expand sales. Afterward, numerous companies started building their own throughout the 1960s and 1970s without licence. Some were direct copies of the Winterburn circuit. In 1971 Bosch bought the European patent rights (German, French, British) from Winterburn. The UK Wireless World magazine of January 1970 published
7254-403: The time. Among the innovations in its early years were the first practical mass-produced four-wheel hydraulic brakes, a system nearly completely engineered by Chrysler with patents assigned to Lockheed , and rubber engine mounts, called " Floating Power " to reduce vibration. Chrysler also developed a wheel with a ridged rim , designed to keep a deflated tire from flying off the wheel. This wheel
7347-492: Was a four-door hardtop with rear-hinged coach doors that listed for US$ 12,800 ($ 135,175 in 2023 dollars ). On April 28, 1955, Chrysler and Philco announced the development and production of the World's First All-Transistor car radio. The all-transistor car radio, Mopar model 914HR, developed and produced by Chrysler and Philco, was a $ 150 option on the 1956 Imperial automobile models. Philco began manufacturing this radio in
7440-624: Was again fined for the 2017 model year for not meeting the minimum domestic passenger car standard. FCA described the $ 79 million civil penalty as "not expected to have a material impact on its business." As part of a January 2019 settlement, Fiat Chrysler was to recall and repair approximately 100,000 automobiles equipped with a 3.0-liter V6 EcoDiesel engine having a prohibited defeat device , pay $ 311 million in total civil penalties to US regulators and CARB , pay $ 72.5 million for state civil penalties, implement corporate governance reforms, and pay $ 33.5 million to mitigate excess pollution. The company
7533-526: Was also introduced for the 1960 model year as a distinct brand. In the U.S. market, Valiant was made a model in the Plymouth line for 1961 and the DeSoto make was discontinued in 1961. With those exceptions per applicable year and market, Chrysler's range from lowest to highest price from the 1940s through the 1970s was Valiant, Plymouth, Dodge, DeSoto, Chrysler, and Imperial. From 1963 through 1969, Chrysler increased its existing stakes to take full control of
7626-555: Was also to pay affected consumers up to $ 280 million and offer extended warranties on such vehicles worth $ 105 million. The total value of the settlement was about $ 800 million, though FCA did not admit liability, and it did not resolve an ongoing criminal investigation. In February 2024, Chrysler unveiled a concept for its first electric vehicle, the Chrysler Halcyon , a battery-electric sedan. As of 2022 , management positions of Stellantis North America include: Chrysler
7719-590: Was brought in to turn the company around, and in 1979 Iacocca sought US government help. Congress later passed the Loan Guarantee Act providing $ 1.5 billion in loan guarantees. The Loan Guarantee Act required that Chrysler also obtain $ 2 billion in concessions or aid from sources outside the federal government, which included interest rate reductions for $ 650 million of the savings, asset sales of $ 300 million, local and state tax concessions of $ 250 million, and wage reductions of about $ 590 million along with
7812-423: Was eventually adopted by the auto industry worldwide. The Maxwell brand was dropped after the 1925 model year, with the new, lower-priced four-cylinder Chryslers introduced for the 1926 year being badge-engineered Maxwells. The advanced engineering and testing that went into Chrysler Corporation cars helped to push the company to the second-place position in U.S. sales by 1936, which it held until 1949. In 1928,
7905-625: Was formed in Ottawa in early 1963 called Hyland Electronics building CD ignitions using the Winterburn design. The discharge capacitor within the CD ignition had the ability to provide a powerful spark in excess of 4 times the spark power of the Kettering system using the same coil, with the exception that spark energy could be maintained at high rpm unlike the Kettering system. The Hyland unit consumed only four amperes at 5000rpm (8cyl) or 10,000rpm(4cyl). Dynamometer testing during 1963 and 1964 showed
7998-426: Was founded in 1925 by Walter Chrysler from the remains of the Maxwell Motor Company . In 1998, it merged with Daimler-Benz , which renamed itself DaimlerChrysler but in 2007 sold off its Chrysler stake. The company operated as Chrysler LLC through 2009, then as Chrysler Group LLC. In 2014, it was acquired by Fiat S.p.A. ; it subsequently operated as a subsidiary of the new Fiat Chrysler Automobiles ("FCA"), then as
8091-502: Was named DaimlerChrysler Motors Company LLC, with its U.S. operations generally called "DCX". The Eagle brand was retired soon after Chrysler's merger with Daimler-Benz in 1998 Jeep became a stand-alone division, and efforts were made to merge the Chrysler and Jeep brands as one sales unit. In 2001, the Plymouth brand was also discontinued. Eurostar also built the Chrysler PT Cruiser in 2001 and 2002. The Austrian venture
8184-541: Was replaced by John Elkann and Michael Manley, respectively. As a result of ending domestic production of more fuel-efficient passenger automobiles such as the Dodge Dart and Chrysler 200 sedans, FCA US elected to pay $ 77 million in fines for violating the anti-backsliding provision of fuel economy standards set under the Energy Independence and Security Act of 2007 for its model year 2016 fleet. It
8277-487: Was sold to Magna International in 2002 and became Magna Steyr . The Voyager continued in production until 2007, whereas the Chrysler 300C , Jeep Grand Cherokee , and Jeep Commander were also built at the plant from 2005 until 2010. On May 14, 2007, DaimlerChrysler announced the sale of 80.1% of Chrysler Group to American private equity firm Cerberus Capital Management , L.P., thereafter known as Chrysler LLC, although Daimler (renamed as Daimler AG ) continued to hold
8370-496: Was the Robert Bosch company which was the pioneer of the first electronic CD ignitions. (Bosch is also responsible for the invention of the high-tension magneto .) During World War Two, Bosch had fitted thyratron (tube type) CD ignitions to some piston engined fighter aircraft. With a CD ignition, an aeroplane engine did not need a warm up period for reliable ignition and so a fighter aircraft could take flight more quickly as
8463-497: Was the SCR, Silicon-controlled rectifier or thyristor invented in the late 1950s that replaced the troublesome thyratron, and paved the way for a reliable solid-state CD ignition. This was thanks to Bill Gutzwiller and his team at General Electric . The SCR was rugged with an indefinite lifetime, but very prone to unwanted trigger impulses which would turn the SCR 'on'. Unwanted trigger impulses in early attempts at using SCRs for CD ignitions were caused by electrical interference, but
8556-519: Was to keep the points, as they were already in use and reliable, and find a way to overcome the 'points bounce' problem. This was accomplished in April 1962 by a Canadian, RCAF officer F.L. Winterburn working in his basement in Ottawa , Ontario . The design used an inexpensive method that would recognize only the first opening of the points and ignore subsequent openings when the points bounced. A company
8649-405: Was tolerant of varied points gaps. The system could be switched back to standard inductive discharge ignition by the swapping of two wires. The Hyland CD ignition was the first commercially produced solid-state CD ignition and retailed for $ 39.95 Canadian. The patents were applied for by Winterburn on September 23, 1963 (United States patent# 3,564,581). The design was leaked to the United States in
