Engine Operation:
The engine operation occurs in four main stages, as its function of any four-stroke engine requires the crankshaft to rotate twice in the machine covering about 720° degree of rotation while on its position.
While, the four main stages for the engine to operate are as follow:
Intake:The fuel is injected inside the piston.Compression:As during the compression the volume is decreased and as more energy is released due to this phase of the engine. Power: During the power stage the expansion of the gases which are compressed before are expanded, providing a power stroke to the engine. Exhaust: The phase during the engine cycle in which the air is exhausted out from the combustion chamber of the engine.
