摘要： An internal combustion engine performs a second mode of combustion where the EGR is less than the EGR gas that peaks the production of soot. The engine then performs a first mode of combustion where the EGR is greater than the EGR that peaks the production of soot. During the second mode, the engine curbs hydrocarbon supplied to an exhaust gas control catalyst by performing a combustion where hydrocarbon does not increase. The exhaust gas temperature discharged becomes relatively high and the EGR rate is set to zero. The engine then increases the hydrocarbon supplied to the catalyst by performing a combustion that increases the hydrocarbon. The temperature of exhaust gas discharged becomes relatively high, and the EGR rate is gradually increased. Accordingly, the engine quickly warms up the catalyst while preventing problems that occur, like clogging of an exhaust gas recirculation passage.

摘要： An internal combustion is capable of switching, during engine operation, between a low-temperature combustion state in which an intake air with a high EGR rate is burned to operate the engine, and a normal combustion state in which an intake air with a low EGR rate is burned to operate the engine. In the internal combustion engine, a pilot injection is executed in addition to a main fuel injection, and furthermore the execution of the pilot injection is restricted during the engine operation with a combustion state switched to the low-temperature combustion state.

摘要： A fuel injector and a spark plug are arranged inside a combustion chamber of an internal combustion chamber. Fuel is injected from the fuel injector at the end of the compression stroke. When the amount of EGR gas is increased, the amount of production of soot peaks. When the amount of EGR gas is further increased, soot is no longer produced. The amount of EGR gas in the combustion chamber is made larger than the amount of EGR gas where the amount of production of soot peaks. Due to this, the production of soot in the combustion chamber is suppressed.

摘要： A first combustion mode in which an amount of an EGR gas within a combustion chamber is higher than that of the EGR gas when a generated amount of soot reaches a peak and substantially no soot is generated. A second combustion mode in which the amount of the EGR gas within the combustion chamber is lower than that of the EGR gas when the generated amount of soot reaches the peak are selectively performed. A catalyst is disposed within an engine exhaust passage wherein a temperature of the catalyst is adjusted so as to be within a predetermined range.

摘要： An internal combustion engine comprising an exhaust gas recirculation system, wherein the amount of EGR gas in the combustion chamber is made larger than the amount of EGR gas where the amount of soot produced peaks when the engine load is comparatively low so as to suppress the temperatures of the fuel and gas around the fuel at the time of combustion in the combustion chamber to a temperature lower than the temperature at which soot is produced. This prevents the production of soot and NOx in the combustion chamber.
