How many cylinders does the CFMoto 250SR have?
1 Answers
CFMoto 250SR uses a single-cylinder water-cooled four-stroke engine with a displacement of 249.2cc. The maximum power output of this engine is 20.5kw. Most motorcycles use four-stroke gasoline engines, whose working principle is essentially the same as that of car engines. A four-stroke gasoline engine operates through four strokes during its working cycle: intake stroke, compression stroke, power stroke, and exhaust stroke. During the intake stroke, the intake valve opens, and the piston moves downward to draw in the combustible air-fuel mixture. In the compression stroke, both intake and exhaust valves close, and the piston moves upward to compress the combustible mixture. During the power stroke, with both valves closed, the spark plug ignites the compressed mixture in the cylinder. The burning mixture forces the piston downward, generating power. In the exhaust stroke, the exhaust valve opens, and the piston moves upward to expel the combustion gases. The four-stroke gasoline engine continuously cycles through these four strokes during operation.
