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.

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.
