Description of Cylinder Head Valves

Cylinder head valves are a critical component of an engine. These valves regulate the intake of the fuel air mixture from the fuel system and the exhaust from the combustion process.
Cylinder Head Valves
The valves themselves are simple parts. Machined out of a single piece of steel, they resemble long rods that flare out at the bottom into a long circular base. Each cylinder in an engine has a minimum of two. One for intake and one for exhaust.
The Valve Train
The cylinder valves are operated by the valve train. The valve train is a series of lifters, roller rocker arms, rods, springs and a cam shaft. The cam shaft turns and oval lobes push the rods up, tilting the rocker arms which push the valve open. As the cam shaft continues to turn, springs on the valve and rods return to their original position and the valve closes.
Cylinder Valve Adjustment
Every maker and model of engines, has its own requirements for adjusting or repairing valves. Special tools to compress valve springs and adjust lash are required. Aftermarket tools and valve trains are a big part of the engine-building community.
