    Abstract: An object of the invention is to provide a fuel injection technique suitable for a spark-ignition internal combustion engine equipped with a first fuel injection valve for injecting fuel into a cylinder, a second fuel injection valve for injecting fuel into an intake passage, and a particulate filter provided in an exhaust passage thereof. To achieve the object, the fuel injection system of an internal combustion engine according to the invention reduces an in-cylinder injection ratio, which is the ratio of the quantity of fuel injected through the first fuel injection valve to the quantity of fuel injected through the second fuel injection valve, when the quantity of particulate matter trapped in the particulate filter is larger than a threshold value, thereby reducing the quantity of particulate matter discharged from the internal combustion engine.

    Abstract: In cases where at the upstream side of an NOx selective reduction catalyst there is provided another catalyst, sulfur poisoning of both the catalysts is recovered in an appropriate manner. To this end, provision is made for an NH3 generation catalyst arranged in an exhaust passage of an internal combustion engine for generating NH3, the NOx selective reduction catalyst arranged in the exhaust passage at a location downstream of the NH3 generation catalyst for reducing NOx in a selective manner, an upstream side recovery unit to recover sulfur poisoning of the NH3 generation catalyst, and a downstream side recovery unit to recover sulfur poisoning of the NOx selective reduction catalyst after the sulfur poisoning of the NH3 generation catalyst has been recovered by the upstream side recovery unit.

    Abstract: In a control of an internal combustion engine control apparatus, the control apparatus includes: a fuel tank that stores a fuel; a vaporized fuel tank that is connected to an intermediate portion of an intake passageway of an internal combustion engine and that stores a vaporized fuel that is formed by vaporization of the fuel; an in-tank fuel supply device that supplies the fuel from the fuel tank into the vaporized fuel tank; and a normally-closed vaporized fuel supply valve that opens and closes a connecting portion between the vaporized fuel tank and the intake passageway. The control apparatus estimates air/fuel ratio in the vaporized fuel tank, and produces the vaporized fuel in the vaporized fuel tank by driving the in-tank fuel supply device, with the vaporized fuel supply valve closed, until the estimated air/fuel ratio becomes substantially zero, during operation of the engine. At the time of starting the engine, the control apparatus supplies the vaporized fuel stored in the vaporized fuel tank into the intake passageway by opening the vaporized fuel supply valve.

    Abstract: A fuel injection apparatus and a fuel injection control method for an internal combustion engine which performs a direct injection operation for injecting fuel from an injector for cylinder injection into a cylinder and a port injection operation for injecting fuel from an injector for intake port injection into an intake port. When a request to change from fuel injection from the injector for cylinder injection to fuel injection from the injector for intake port injection is made, the fuel injection mode of a particular cylinder is changed at a point of time according to the changing request for the particular cylinder. Accordingly, transition to the optimum fuel injection mode is performed in a short time, and a required amount of air-fuel mixture can be obtained. It is therefore possible to suppress fluctuation of torque and deterioration of emission.
