Abstract
The invention relates to a method and apparatus for operating an internal combustion engine whereby to obtain maximum efficiency concomitant with minimum pollution of the atmosphere due to the discharge of exhaust gases. The engine is fueled with a stratified charge of a combustion supporting gaseous mixture, followed by the force injection of a fluidized fuel. To assure proper combustion, particularly at low loads, the intake volume of said combustion supporting medium is throttled. The conditions resulting within each combustion chamber are enrichment of the combustible charge and higher temperatures. As progressively greater loads are applied to the engine, the throttling action is progressively reduced to maintain a combustible, yet lean, mixture to midload. Further increase in load is accomplished by enrichment through increased fuel input.
