摘要： A failure determination system and method for an internal combustion engine and an engine control unit are provided which are capable of properly determining a failure of a variable valve mechanism for inactivating a valve system associated with at least one of cylinders during a predetermined operation of the engine, by discriminating a misfire caused by the failure of the mechanism from a normal misfire. Fuel injection valves inject fuel for each cylinder and oxygen concentration of exhaust gases is detected. A misfire condition is detected on a cylinder-by-cylinder basis. Fuel injection to a misfiring cylinder is stopped. A failure of the mechanism is determined, when a parameter based on the oxygen concentration detection indicates a richer value of an actual air-fuel ratio of the exhaust gases than a predetermined reference value does, under a condition of the fuel injection being stopped.

摘要： A method for detecting an abnormality in a hybrid vehicle. The hybrid vehicle includes an engine that can run in a cylinder cut-off state where intake and exhaust valve lifts are made zero, and a motor/generator that functions as both a motor and a generator. The vehicle travels by means of the power of at least one of the engine and the motor/generator and carries out regenerative braking by the motor/generator while running the engine in a cylinder cut-off state during deceleration. When detecting an abnormality in a negative intake pressure sensor or an EGR control valve based on the negative intake pressure of the engine, the engine is prohibited from running in a cylinder cut-off state even during deceleration, thus generating a negative intake pressure and thereby enabling the abnormality detection to be carried out without any problems.

摘要： A control system for an internal combustion engine having an intake system and an exhaust system is disclosed. The exhaust system includes a catalyst, and the intake system includes a throttle valve. The engine is mounted on a vehicle having a brake booster to which an intake pressure at downstream of the throttle valve is introduced. The catalyst temperature rise control in which the intake air amount is increased after starting of the engine and the ignition timing is retarded according to a rotational speed of the engine is performed. When a pressure difference between the detected intake pressure and the atmospheric pressure during the catalyst temperature raising control is less than a predetermined pressure, the increased intake air amount and the retard amount of the ignition timing is gradually decreased.

摘要： A throttle valve control system for an internal combustion engine installed in a vehicle. A throttle valve opening sensor detects an actual opening of a throttle valve, and an ECU calculates a desired opening of the throttle valve according to the rotational speed of the engine and the required torque of the engine, which is calculated according to operating conditions of the engine and operating conditions of the vehicle, and electrically controls the throttle valve such that the detected actual opening of the throttle valve becomes equal to the desired opening of the throttle valve. An intake pressure sensor detects actual intake pressure within the intake passage, and desired intake pressure within the intake passage is calculated according to the rotational speed of the engine and the required torque of the engine. The desired intake pressure is compared with the detected actual intake pressure, and the desired opening of the throttle valve is corrected based on results of the comparison.
