exhaust valves
Combustion exit gates
Exhaust valves are components in internal combustion engines that open to release burned gases from the cylinder after combustion.
They work in sequence with intake valves—intake valves let fresh air-fuel mixture in, exhaust valves let spent gases out.
The timing and condition of exhaust valves critically affect engine performance: The mechanic said my exhaust valves were burned.
