Engine Intake and Exhaust Valve Basics Location Function

There are two types of engine valves; intake and exhaust valves. The intake valves of course let air in, and the exhaust valves let exhaust air out. The more air you can move air in and out of the engine the more efficient, and therefor power the engine will have. This is why the engine valve plays a pretty critical role in an engines performance.
