Combustion engine i.e. diesel engine, for use in motor car, has gaseous mixture containing fresh inlet air and inert gas and supplied to interior of intake gas passage when engine body is in intake stroke
The engine i.e. diesel engine (10), has an intake gas system (12) that forms an intake gas passage (32). A waste gas system (14) forms an exhaust gas passage (34) in which exhaust gas is delivered by a combustion chamber (27). A control device (16) controls an inert gas supply valve (15) to open and close an inert gas supply passage (42), in order to adjust time period for supplying fresh inlet air into the intake gas passage. A gaseous mixture contains fresh inlet air and inert gas, and is supplied to an interior of the intake gas passage when an engine body (11) is in intake stroke.
