ABSTRACT:
A method of operation of a four-stroke internal combustion engine having an intake, a combustion chamber coupled to the intake, an exhaust coupled to the combustion chamber and an exhaust recirculation device connecting the exhaust to the intake. The method includes admitting exhaust gas into the combustion chamber which is recirculated by the recirculation device from the exhaust into the intake. Thereafter, a mixture of air and fuel to be combusted is admitted through the intake into the combustion chamber which produces a stratification in the combustion chamber of the mixture of air and fuel and the exhaust gas. The stratified contents of the combustion chamber are then combusted by self-ignition.
