    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: In an internal combustion engine having an in-cylinder pressure sensor provided on each cylinder, an in-cylinder pressure detection value is corrected into an absolute pressure using an absolute pressure correction value Pr by calculating the absolute pressure correction value Pr (=(P2V2κ−P1V1κ)/(V1κ−V2κ)) from in-cylinder pressure detection values P1 and P2, in-cylinder volumes V1 and V2, and a specific heat ratio K at predetermined crank angles θ1 and θ2 during the adiabatic compression stroke from IVC to the ignition timing. When the adiabatic compression stroke (ignition timing−IVC) is shorter than a predetermined crank angle period CAth, the ignition timing is delayed. When the adiabatic compression stroke is longer than or equal to CAth, IVC is advanced. Preferably, a torque variation is suppressed by controlling the ignition timing of each cylinder before IVC is advanced.

    摘要: An object of the present invention is to be able to execute motor assist only when it is necessary at a time of starting an engine, and drive a motor efficiently. An engine 10 includes a starter motor 34 for aiding in starting, and performs motor assist by the starter motor 34 in accordance with necessity when the engine is to start independently by combustion. An ECU 50 predicts a torque T1 that is generated in an initial explosion cylinder at a time of starting before actual combustion, and performs independent starting without driving the motor 34, when the prediction torque T1 is a starting request torque Ts1 or more. When the prediction torque T1 is less than the starting request torque Ts1, the ECU 50 drives the motor 34 and performs starting by motor assist. Thereby, power consumption of a battery and the like can be suppressed by decreasing wasteful drive of the motor, and the starter motor 34 can be efficiently driven while startability is secured.

    摘要: A control apparatus and control method is provided for an internal combustion engine that includes a vaporized fuel tank in which vaporized fuel is stored, and a normally-closed vaporized fuel supply valve that opens and closes a connecting portion between the vaporized fuel tank and a surge tank. This apparatus and method produce vaporized fuel by injecting fuel into the tank while the vaporized fuel supply valve is closed while the engine is operating, then open the vaporized fuel supply valve at engine startup and supply the vaporized fuel stored in the tank to the surge tank. If there is no vaporized fuel remaining in the vaporized fuel tank when the engine stops, vacuum is generated in the vaporized fuel tank by temporarily opening the vaporized fuel supply valve before the engine stops. Vaporized fuel is then produced by injecting fuel into the vaporized fuel tank in this vacuum state.

    摘要: An intra-cylinder pressure sensor fault diagnostic device that ensures an opportunity for fault diagnosis in a wide operation region, and can accurately detect an intra-cylinder pressure with a high S/N ratio. The fault diagnostic device for an intra-cylinder pressure sensor, which outputs a value corresponding to an intra-cylinder pressure of an internal combustion engine delays ignition timing so that firing timing comes after a compression top dead center to generate peaks of the intra-cylinder pressure before firing and after firing respectively. When the ignition timing is delayed, at least one of an output value of the intra-cylinder pressure sensor in the peak of the intra-cylinder pressure before firing (hereinafter, called a pre-firing output peak value) and a crank angle thereof is detected. A fault of the intra-cylinder pressure sensor is determined by using at least one of the pre-firing output peak value and the crank angle thereof
