Engines have two main valves and they are intake and exhaust. For any mechanical or automobile student or engineer, these two things are just routinely talked about and worked on. But what is an exhaust valve and what does it do? And where is it located? This kind of valve does exactly the opposite of intake valve, which is to let air out from the engine at the right time with the right amount of it. The location of this valve is in the head of the cylinder.

If exhaust valve fails to function properly or efficiently, the whole engine would lose its value and hence keeping a check on both intake and exhaust valves is necessary to have an efficient running engine.
