It consists of a cylinder block,cylinder head kit,piston kit,cylinder liner kit,crankshaft and camshaft, flywheel group. In the work stroke, the piston is subjected to gas pressure in the cylinder for linear movement, through the connecting rod into the rotating motion of the crankshaft, and from the crankshaft output power. In the intake, compression and exhaust stroke, the flywheel releases energy and converts the rotating motion of the crankshaft into the linear motion of the piston.
