Boosted direct injection stratified charge gasoline engines

摘要: An arrangement of a four cycle internal combustion engine 7 is provided. In the preferred embodiment has plurality chambers 18 having reciprocating pistons 22 mounted therein. A fuel injector 80 provided for each chamber. The injects stratified charge into chamber upon compression stroke piston . intake manifold 32 to provide air charging device 38 pressurize within Preferably variable geometry turbocharger pressurizing allows extend operation and facilitates in increased gas mileage by allowing stay mode longer than prior charged engines.
