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