Engine valve

Engine valves are mechanical components used in internal combustion engines to allow or restrict the flow of fluid or gas to and from the combustion chambers or cylinders during engine operation. ... More information concerning other about other valve types may be found in our related guide Understanding Valves.


How do valves work in a engine? In theory, the valve operation is very simple: the cam pushes the valves down into the cylinder against the spring, opening the valve so gases can flow and then lets the valve shut under the force of the spring. The pressure in the combustion chamber rather neatly helps seal the valve shut.

Causes and possible consequences of valve failures in the engine
Causes and possible consequences of valve failures in the engine
The valve doesn't close properly? Possible causes include incorrect valve clearance setting, or failure to rework the valve seat ring or valve guide in the center. Too large or too small a valve gap can also be fatal.
What are the causes of engine valve failure?
What are the causes of engine valve failure?
When one or more of these valves is damaged, the result can be reduced power and low fuel consumption, or even complete engine failure.The two most common types of valve failure are bent/broken valves and burned valves.
What is the cause of the engine valve that keeps ringing?
What is the cause of the engine valve that keeps ringing?
What is valve ringing?After the vehicle starts, the engine makes a rhythmic "da da da" sound similar to metal percussion, which increases with the speed of the engine.Under normal circumstances, the engine is not a long time to make this noise, most are in the cold start after a short time sound, then slowly disappear, this is the valve ring.
