Abstract: 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.

Abstract translation: 内燃机执行第二燃烧模式，其中EGR小于使烟灰产生达到峰值的EGR气体。 然后，发动机执行第一燃烧模式，其中EGR大于产生烟灰的EGR。 在第二模式中，发动机通过进行不增加烃的燃烧来控制供给排气控制催化剂的碳氢化合物。 排放的废气温度相对较高，EGR率设定为零。 然后，发动机通过进行增加烃的燃烧来增加供应给催化剂的烃。 废气排放的温度相对较高，EGR率逐渐增加。 因此，发动机可以在防止出现诸如排气再循环通道堵塞的问题的同时快速加热催化剂。

Abstract: 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.

Abstract: 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.

Abstract: 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.
