syöttöventtiili

Syöttöventtiili, also known as an intake valve or inlet valve, is a crucial component in internal combustion engines. Its primary function is to control the flow of the air-fuel mixture or just air into the engine cylinder during the intake stroke. The valve is typically a mushroom-shaped disc that seals against a valve seat within the cylinder head. When the piston moves down, creating a vacuum, the camshaft mechanism opens the syöttöventtiili, allowing the mixture or air to enter the cylinder. Once the cylinder is filled, the camshaft rotates, closing the valve and sealing the combustion chamber for the compression stroke. The timing of the syöttöventtiili opening and closing is critical for engine performance, efficiency, and emissions. Factors such as valve size, lift, and duration influence the amount of charge that can enter the cylinder. In modern engines, syöttöventtiilit are often made from durable materials to withstand the high temperatures and pressures within the engine.
