摘要： A dual-injector fuel injection engine has intake ports (11) each extending at cylinder head (6) obliquely upward from a combustion chamber (16); an intake manifold (21) connected at its downstream side end section to the intake ports (11); an in-cylinder injector (15) for each of the cylinders, injecting fuel directly into the combustion chamber (16); and an intake pipe injector (56) for each cylinder, injecting fuel into the intake port (11). The in-cylinder injector (15) is attached to the cylinder head (6) and is positioned on the lower side of the intake port (11) when viewed from the direction of the axis of a crankshaft (27). The intake pipe injector (56) and a low-pressure delivery pipe (57) for supplying fuel to all the intake pipe injectors (56) are supported at the intake manifold (21), and are positioned, when viewed from the direction of the axis of the crankshaft (27), on the upper side of the intake port (11) so as to be close to the intake port (11).

摘要： An object of the present invention is to provide a technology that enables reduction of NOx stored in an NOx catalyst with improved efficiency in an exhaust gas purification system for an internal combustion engine. According to the present invention, when NOx stored in the NOx catalyst is to be reduced, if the temperature of the NOx catalyst is lower than a specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased only by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine, and if the temperature of the NOx catalyst is not lower than the specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased either only by adding reducing agent through reducing agent addition means, or by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine and adding reducing agent through the reducing agent addition means.

摘要： An object of the present invention is to provide a technology that enables better reduction of NOx stored in an NOx catalyst in an exhaust gas purification system for an internal combustion engine. According to the present invention, when NOx stored in an NOx catalyst is to be reduced, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to a target air-fuel ratio by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine. In doing so, if the temperature of the NOx catalyst is not lower than a specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to the target air-fuel ratio while bringing the combustion state into low temperature combustion (S104, S105). On the other hand, if the temperature of the NOx catalyst is lower than the specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to the target air-fuel ratio while decreasing the quantity of EGR gas in a cylinder so that the amount of generated smoke is kept within an allowable range (S107, S105).
