An Engine Inlet Valve allows air and fuel to enter the combustion chamber during the intake stroke. It is made of durable material, to withstand the high temperatures and pressures that are present in the combustion chamber. The Valve is placed at the top of the engine's cylinder head and is usually opened by a camshaft, which is driven by the engine's crankshaft.Attributes:• By regulating the air-fuel mixture, the engine can operate with maximum power output and minimum emissions• Optimize airflow into the combustion chamber for efficient engine performance Applications:An Engine Inlet Valve opens and closes to allow the air-fuel mixture to enter the combustion chamber, the inlet valve opens to let the mixture in, and then it closes during the compression and power strokes to seal the combustion chamber.
