摘要： PROBLEM TO BE SOLVED: To provide an engine of a compression and ignition type having improved noise and fuel consumption while reducing exhaust emission. SOLUTION: Fuel is injected from a nozzle of an injector 11 at an almost constant injection rate in an atomized and easily evaporated form and passed through a cylinder atmosphere. The space distribution of the injected fuel is formed where fuel and air are mixed more as located farther from the nozzle to the direction of injection and a premixture region exists with the fuel premixed and evaporated. The concentration of oxygen in the cylinder of the internal combustion engine and the time length of an ignition delay are controlled so that the rate of a preignition injection amount before starting ignition to the total injection amount at one fuel injection is 25-50% and combustion occurs in the formed premixture region in sequence. Thus, gradual premixture combustion is achieved. COPYRIGHT: (C)2005,JPO&NCIPI
