Precautions
All parts must be cleaned before being checked, and purged with high-pressure air.
Function of cylinder block: It offers a space for gas compression, combustion and expansion,
and guides in piston motion.
It also transfers some of heat to surrounding cooling media.
Function of piston:
1. Withstand pressure as a result of combustion of combustible mixed gas, and transfer such
pressure to the connecting rod to drive the crankshaft.
2. Form the combustion chamber along with the cylinder cover.
Precautions
All parts must be cleaned before being checked, and purged with high-pressure air.
