electric cub motorcycles at the top dead center

A, the only point: piston rod connected to the crank assembly, electric cub motorcycles the piston has upper and lower limit positions in the cylinder, an upper limit position is called the point which the top dead center of the crankshaft centerline distance is maximum. Lower limit position is called the bottom dead center, which is the minimum distance between the center line of the crankshaft. B, piston stroke: two wheel chopper motorcycle the piston moves to the distance from a point called the stroke bottom dead point only, also known as stroke. C, the working volume of the cylinder: a piston stroke of cylinder swept space. D, the working volume of the combustion chamber: electric cub motorcycles the piston at the top dead center, the piston top center of the combustion chamber with the cylinder head space at the top thereof. E, bes tmotorcycle engine the total volume of the cylinder: the cylinder working volume of the combustion chamber volume of work. F, compression ratio: an important structural parameters of the engine, which directly affects the engine power.
