An engine valve is considered as a vital component of a combustion engine. It is found in the cylinder head of a car. There are two types of engine valves, the exhaust valve and the intake valve. Intake valves draw in the fresh fuel-air combo to the engine for combustion, while the exhaust valves permits gaseous by-products out of your car engine. These valves stay active as long as your car motor engine is running, they open and close in a certain sequence depending upon the position of the pistons in each cylinder.
The camshaft regulates the opening and closing of valves. It triggers an engine valve to go up when the necessity arises and allow gaseous exchange in the engine. As soon as this job is accomplished valves return down with a spring and closes the air passage, this creates optimum level of compression inside the combustion chamber. Generating compression inside the combustion chamber is very essential for the engine to run and to ignite the fuel and drive the pistons.
Now you know that the operation or closing and opening of valves are regulated by a camshaft. The cam is in most cases a flat piece of metal which has a unique style to serve its specific purpose. The cam is generally attached to a support that rotates easily and is known as a shaft. This design is often referred to as cam followers and is capable of creating a specific motion that helps the valves to open and close. As the cam rotates the shape or profile of the cam causes the follower to move along with it in a particular way. The follower is free to move in the Y-plane but is unable to move in any other plane. In brief, the valves and the cam shaft together form the cam followers and are crucial in running of a car engine.
In most types of reciprocating combustion engines, valves are supported by valve guides. A valve guide is a tube-shaped piece of metal fixed into the cylinder head with the valves reciprocating inside it. Valve guides support and center the intake and exhaust valves as they open and close. Due to this guides experience a lot of wear and tear. One thing that will always help you with your engine's optimum performance is replacing worn out valve guides. Worn out guides can cause the engine valves break off from the stem. Do care to count on worn guides each time you go for servicing of your car engine.
Valve manufacturers all over the world are producing great quality valves these days by employing different raw materials in their production. Stainless steel, copper, brass, plastic and different types of alloys are used in the production of different types of valves. Stainless steel valves are much popular among other valves because of their wear and tear resistance capability and easy replacement options. They are operating successfully in commercial, industrial, military, residential, heating and cooking equipments.
You can get large number of online dealers that sales valves made up of different materials including stainless steel valves.
