Valve Timing IC Engine

Valve Timing Points : Valve Timing The inlet valve unlocks through the suction stroke also the exhaust valve open in the exhaust stroke. The precise moment at which all of the valves opens and closes with location to the place of piston. In theory, the inlet valve opens precisely the start of suction stroke and closes at the end of the stroke. Equally the valves stay closed through compression and power strokes. The exhaust valve opens exactly at the start of exhaust stroke and close at the finish of the stroke.
