摘要： A stable combustion without generating smoke or misfire is performed by selectively conducting a first combustion mode and a second combustion mode. In the first combustion mode, an amount of an inert gas, e.g., EGR gas, provided to a combustion chamber is made to be larger than an amount of the inert gas that causes the generation amount of soot to become a peak amount. This causes substantially no soot to be generated. In the second combustion mode, the amount of the inert gas provided to the combustion chamber is made to be smaller than the amount that causes the generation amount of soot to become a peak amount. The injection timing is quickened if the injection amount is increased in the first combustion mode, and the injection timing is delayed if the injection amount is reduced.

摘要： An engine where first combustion where the amount of the EGR gas in the combustion chamber is larger than the amount of EGR where the amount of production of soot peaks and almost no soot is produced and a second combustion where the amount of EGR gas in the combustion chamber (5) is smaller than the amount of EGR gas where the amount of production of soot peaks are selectively switched between. When switching between the first combustion and second combustion, the injection timing is delayed until after top dead center of the compression stroke,

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.
摘要翻译：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。

摘要： According to the invention, there is provided an exhaust gas purification device for purifying an exhaust gas discharged from an engine having cylinders including first and second cylinders. An exhaust stroke in the first cylinder is carried out next to an exhaust stroke in the second cylinder. The exhaust gas purification device comprises exhaust branch passages which are connected to the cylinders, respectively. The exhaust branch passages include first and second exhaust branch passages which are connected to the first and second cylinders, respectively. The exhaust gas purification device comprises a common exhaust passage connected to the exhaust branch passages, a catalyst positioned in the common exhaust passage for purifying an exhaust gas, and an exhaust gas recirculation passage connected to the first exhaust branch passage. The exhaust gas recirculation passage introduces the exhaust gas from the first exhaust branch passage into an intake passage which is connected to the cylinders. According to the invention, a reducing agent is fed to only the second cylinder during the power or the exhaust stroke in the second cylinder to promote the purifying operation of the catalyst when the exhaust gas is introduced into the intake passage via the exhaust gas recirculation passage.

摘要： According to the present invention, there is provided a fuel injecting device for injecting fuel into a cylinder of an engine. A fuel injector injects a main fuel charge into the cylinder at a predetermined first timing, and the fuel injector injects additional fuel into the cylinder at a predetermined second timing which is different from the predetermined first timing. It is judged if an amount of fuel adhering to an inner wall of the cylinder is larger than a predetermined fuel amount when the fuel injector injects the additional fuel. The fuel injector inject the additional fuel such that an amount of fuel adhering to the inner wall of the cylinder becomes smaller than the predetermined fuel amount when it is judged that an amount of fuel adhering to the inner wall of the cylinder is larger than the predetermined fuel amount.
