A single-cylinder engine , sometimes called a thumper , is a piston engine with one cylinder . This engine is often used for motorcycles , motor scooters , motorized bicycles , go-karts , all-terrain vehicles , radio-controlled vehicles , power tools and garden machinery (such as chainsaws , lawn mowers , cultivators , and string trimmers ). Single-cylinder engines are made both as 4-strokes and 2-strokes .
7-477: The Yamaha TW200 is a 196 cc single cylinder dual-sport motorcycle manufactured and marketed by Yamaha since 1987. TW is short for Trail Way. In 2001 an update was made that removed the kick start and replaced the front drum brake with a disc brake. Due to its large tires, it has been compared to the 2-wheel-drive Rokon and has been called a "two-wheeled quad". In a review of the 2020 model, Ultimate Motorcycling said, "If you're patient and persistent,
14-716: A four-stroke cycle ), however diesel single-cylinder engines are also used in stationary applications (such as the Lombardini 3LD and 15LD). A variation known as the split-single makes use of two pistons which share a single combustion chamber. Early motorcycles , automobiles and other applications such as marine engines all tended to be single-cylinder. The configuration is almost exclusively used in portable tools, along with garden machinery such as lawn mowers. Single cylinder engines also remain in widespread use in motorcycles, motor scooters , go-karts , auto rickshaws , and radio-controlled models . From 1921 to 1960,
21-583: A 49 cc (3.0 cu in) four-stroke single-cylinder engine. There are also several single-cylinder sportbikes (such as the KTM 690 Duke R ), dual-sport motorcycles (such as the BMW G650GS ) and the classic-styled Royal Enfield 500 Bullet . The Moto3 class in the MotoGP World Championship have used four-stroke 250 cc (15.3 cu in) single cylinder engines since
28-486: The Lanz Bulldog tractor used a large horizontally-mounted single cylinder two-stroke engine. However they are rarely used in modern automobiles and tractors, due to developments in engine technology. Single cylinder engines remain the most common engine layout in motor scooters and low-powered motorcycles . The Honda Super Cub (the motor vehicle with the highest overall sales since its introduction in 1958) uses
35-512: The TW can take you almost anywhere." This motorcycle, scooter or moped-related article is a stub . You can help Misplaced Pages by expanding it . Single cylinder engine Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces
42-467: The vibration level, they often make greater use of balance shafts than multi-cylinder engines, as well as more extreme methods such as a dummy connecting rod (for example the Ducati Supermono ). These balancing devices can reduce the benefits of single-cylinder engines regarding lower weight and complexity. Most single-cylinder engines used in motor vehicles are fueled by petrol (and use
49-437: The weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than a comparable multi-cylinder engine, resulting in relatively slower changes in engine speed. To reduce
