    Abstract: 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.

    Abstract: 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.

    Abstract: This invention determines whether or not an internal combustion engine is performing combustion, and if the determined result is that the engine is not performing combustion, it is determined whether or not the engine revolution speed is greater than a predetermined revolution speed NEth. If it is found that the relation that the revolution speed>predetermined revolution speed NEth holds, an in-cylinder maximum pressure value Pmax during motoring is identified by an in-cylinder pressure sensor 34, a crank angle θPmax corresponding to the relevant Pmax is detected by a crank angle sensor 42, and the crank angle is corrected so that θPmax becomes TDC. Further, the crank angle correction amount is learned, and the relation between the signal of the crank angle sensor 42 and the actual crank angle (measured value) corresponding thereto is corrected.

    Abstract: A control device for an internal combustion engine. An object of the present invention is to provide a control device for an international combustion engine for highly accurate absolute pressure correction irrespective of the length of an adiabatic compression stroke period. When the number of cylinders in an engine is n (n is an integer of 2 or more), an adiabatic compression stroke period of one cylinder preceding another cylinder to be corrected into its absolute pressure by a 1/n cycle (ignition timing —IVC) is compared with a threshold CATH (step 100). In the step 100, the absolute pressure correction is carried out based on PVκ=constant when the adiabatic compression stroke period is longer than the threshold CATH (step 110). On the other hand, the absolute pressure correction is carried out based on a value PIP detected by an intake pipe pressure sensor when the adiabatic compression stroke period is shorter than the threshold CATH.

    Abstract: 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.

    Abstract: 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.
