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