Exhaust volume

Displacement refers to the ability to deliver all air and mixture to all cylinders during a certain cycle
of the engine. It also refers to the volume that a piston can travel from one stroke to another.

Engine displacement = single cylinder displacement × cylinder number single cylinder displacement =
(π × bore diameter × bore diameter) ÷ 4 ÷ 1000 × stroke (unit cc) Generally, the cylinder displacement
is only an approximate value, generally higher than the target The value, not to say that it is exactly 48cc
but certainly not more than 49cc. The bore diameter refers to the diameter, the unit is usually mm, and the
unit conversion needs to be divided by 1000.
