There are a lot of new engines which would have overhead cam assemblies. There would be other designs which would be located in the camshaft lower in the engine and would utilize the push rods to move valve assemblies. Now you must be thinking that how would a camshaft rotate? The answer to this is that a camshaft would be rotated by a timing belt, timing chain or direct gear.

Types Of Valve Train

Are you searching for the different types of valve train? Then don’t worry! All you have to do is to have a look below and then all your doubts regarding its types would be cleared. Generally, there are two basic types of valve train.

How Does Valve Train Works?

Are you searching how do the valve train actually work? Then all you have to do is to have a look below and then you will be able to understand everything.

 

  • There are a lot of engine subsystems which can be implemented by utilizing a lot of technologies, as well as better technologies which would improve the performance of the engine. Now let us look at various subsystems which are utilized in the latest engines, starting with the valve train.
  • The valve train consists of the valves as well as a mechanism which would open up and then close them. The opening as well as closing system would be known as a camshaft. There would be lobes on the camshaft which would move the valves up and down.
  • There are a lot of latest engines which would have what is known as overhead cams. It would mean that the camshaft would be situated above the valves. The cams on the shaft would activate the valves directly or through a very short linkage. The engines which are old would utilize a camshaft which is situated in the sump near the crankshaft.
  • It is the timing belt or timing chain which would link the crankshaft to the camshaft so that the valves would be in sync with the pistons. The camshaft would be geared up to turn at one-half the rate of the crankshaft. There are a lot of high-performance engines which would have four valves per cylinder (two intakes, two for exhaust), and then this arrangement would need two camshafts per bank of cylinders, that is the reason why they are known as "dual overhead cams."
