INLET VALVE FOR OPEL Z16XEP/16XE1 A16XER 1.6L 4cyl ASTRA H CHEVROLET LXT 1.6L SWAG 40 92 8640

The SWAG brand Inlet Valve has the function of connecting the intake manifold to the cylinder depending on the timing of the distribution, they are usually made of solid metal steel with chromium and silicon alloy, which provides good heat and performance resistance.

The metal of some areas is usually hardened to reduce wear, such as the seat, stem, and plate.

The cooling of this valve is largely due to its contact with the combustible air mixture, which largely dissipates its temperature normally in contact with the stem, and its operating temperature is 200ºC to 300ºC.

The principle of the inlet valve work

The piston moves down due to the action of the cam, when this happens, it pulls the mixture, which passes through the gap left by the valve when it is opened. They are located in the cylinder head, the valve disc rests on the cylinder head, completely covering the opening to prevent the air / fuel mixture from escaping outward. On the other hand, the stem, which is the longest part of the valve, is driven by the camshaft.
