Xinchai 4d30g31 refers to the engine parts number. Engine principle: Mixing air and gasoline in a certain proportion to form a good mixture, which is drawn into the cylinder during the intake stroke. The mixture is compressed, ignited, and burned to produce thermal energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to perform reciprocating linear motion, and outputting mechanical energy externally through the connecting rod, crankshaft, and flywheel mechanism. Engine composition: The engine consists of two major mechanisms: the crank connecting rod mechanism and the valve mechanism, as well as five major systems: cooling, lubrication, ignition, fuel supply, and starting systems. The main components include the cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc.
