    摘要： A system and method for widening auto-ignition range of a lean burn internal combustion engine employs stratified charge of exhaust gas content and air content. A fuel injection system carries out a first injection of gasoline fuel for dispersion within the air content, and a second injection of gasoline fuel for dispersion within the exhaust gas content. This intelligent injection of gasoline fuel accomplishes auto-ignition of gasoline fuel within the exhaust gas content over extended range of engine speed and load.

    摘要： An enhanced auto-ignition in a gasoline internal combustion engine, comprises a fuel injector directly communicating with said combustion chamber for spraying gasoline fuel. The fuel injector sprays a first injection quantity of gasoline fuel into a combustion chamber at first fuel injection timing, which falls in a range from the intake stroke to the first half of the compression stroke, thereby to form air/fuel mixture cloud that becomes a body of mixture as the engine piston moves from the first fuel injection timing toward a top dead center position of the compression stroke, and the fuel injector sprays a second injection quantity of gasoline fuel into the body of mixture at second fuel injection timing, which falls in the second half of the compression stroke, forming mixture cloud that is superimposed on a portion of said body of mixture, thereby to establish the cylinder content wherein the density of fuel particles within the superimposed portion is high enough to burn by auto-ignition at an ignition point in the neighborhood of the piston top dead center position of the compression stroke, causing temperature rise and pressure, which initiate auto-ignition of the fuel particles within the remaining portion of said body of mixture.

    摘要： An internal combustion engine has a fuel injection system capable of performing a multiple injection wherein a main injection event and a trigger injection event take place in this order in one cycle. With main injection, fuel is widely dispersed within a combustion chamber to create a main mixture for main combustion. With trigger injection, fuel is dispersed locally within the combustion chamber to create an ignitable mixture for auto-ignition. Auto-ignition of the ignitable mixture creates condition under which auto-ignition of the main mixture takes place. Fuel quantity and timing for each of main and trigger injections are varied corresponding to engine speed and load request to cause the main mixture to burn at a target crank angle after TDC of compression stroke.
