The inlet valve in a motorcycle engine controls the entry of air and fuel mixture into the combustion chamber. It opens and closes in response to the engine's camshaft movements, allowing the air-fuel mixture to enter the cylinder during the intake stroke. Made from durable materials like stainless steel or heat-resistant alloys, the inlet valve must withstand high temperatures and pressures. Proper functioning of the inlet valve is crucial for efficient engine performance, smooth operation, and optimal fuel combustion.
