Abstract
A decompressor for use in an internal combustion engine is disclosed The decompressor is at least partially located within the venting passageway in response to pressure in the combustion chamber for selectively opening the venting passageway such that combustion gas located within the chamber is vented to the induction passageway. The decompressor opens the venting passageway when the engine is off and during an engine start up operation.
