摘要： An EGR apparatus includes a EGR passage and an EGR valve provided in the EGR passage to regulate an EGR flow rate in the EGR passage. An ECU closes the EGR valve from an open state prior to start of deceleration of the engine based on engine rotation speed detected by a rotation speed sensor, accelerator opening degree detected by an accelerator sensor, and actual opening degree of the EGR valve. During deceleration of the engine, the ECU obtains a target opening degree of the EGR valve according to the separately detected engine rotation speed and accelerator opening degree from a target opening degree map and starts to close the EGR valve when a difference between an actual opening degree and the target opening degree of the EGR valve exceeds a predetermined value.

摘要： 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.

摘要： 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.

摘要： An engine includes a normal fuel tank, fuel gas tank, an in-tank injection valve and a fuel gas supply valve. During operation of the engine, in a state where the fuel gas supply valve is closed, a fuel is injected into the fuel gas tank through the in-tank injection valve to generate a fuel gas by vaporizing the fuel. The fuel gas is stored in the fuel gas tank and is maintained in the gas phase due to the natural decompression even after the engine is stopped. To start the engine, the fuel gas supply valve is opened to supply the fuel gas in the fuel gas tank to a surge tank. Thus, compared with the case where the fuel gas is generated at the start of the engine, the fuel gas can be quickly supplied into the cylinder, so that the ability to start the engine is improved.
