Supercharged internal combustion engine with scavenging of the burnt gas and at least two intakes

摘要

The engine has a burnt gas sweeping inlet unit (14) and a fuel injection inlet unit (16) provided with manifolds (18, 20) that is controlled by inlet valves (22, 24). A burnt gas exhaust unit has an exhaust valve (34) associated to an exhaust manifold (36) and fuel injection units. The fuel injection inlet unit has an injector (26) with noses (28, 30) supplying a fuel e.g. petrol, to the fuel injection inlet unit in an operating mode of the engine and to the burnt gas sweeping inlet unit and the fuel injection inlet unit in operation of the engine by the noses.
