exhaust valve

exhaust valve
[1] The valve through which the burned fuel charge passes on its way from the cylinder to the exhaust manifold. It is driven by the camshaft. When comparing an exhaust valve with an intake valve in the same engine, the part of the exhaust valve that seats into the head (i.e., not the stem) will have a smaller diameter than the intake valve.
[2] A movable port which provides an outlet for the cylinder gases in a compressor or engine.
