635-8664: Engine Exhaust Valve

An Engine Exhaust Valve is located in the cylinder head, this valve opens at precise moments during the engine cycle to release the hot, burnt exhaust gases produced during combustion. Once the exhaust gases are expelled, the valve closes to seal the combustion chamber, allowing fresh air-fuel mixture to be drawn in for the next cycle. It consists of a valve stem, valve head, and valve seat. The valve stem connects the valve head to the valve system, allowing it to open and close. Attributes: • Withstands the high temperatures and corrosive environment of engine exhaust gases • Exhibits good wear resistance against the abrasive nature of hot exhaust gases flowing past the valve seat Applications: An Engine Exhaust Valve opens to release the burned gases from the combustion chamber into the exhaust system. The opening and closing of the exhaust valve are precisely timed and synchronized with the engine's operation through the camshaft and valve train system.
