As shown in Fig. 14, it is equipped with a cylinder a, a piston b with a piston ring f, a cylinder cover c, an exhaust valve d, a fuel valve e, etc. When the piston b reaches near the top dead center, fuel flows from the combustion valve e into the combustion chamber. The piston b is injected into the interior of g and combusted, and the pressure rise due to the energy pushes the piston b downward in the figure, rotating the crankshaft (not shown) and producing output.
The structure is such that the piston moves back upwards due to inertia and operates by repeating the movement, and each piston ring f slides on the cylinder A-liner due to the reciprocating movement of the piston, causing wear.
