摘要： A failure determination device capable of performing failure determination for a shutter device of a vehicle with accuracy in a short time period. In an engine room of a vehicle, a condenser for a refrigeration cycle for an aircon is provided and at a front grille of the vehicle, a grille shutter device is provided for introducing ambient air for cooling the condenser into the engine room by opening a grille shutter. According to the failure determination device of the shutter device, a pressure of the refrigerant discharged from the condenser is detected as a refrigerant pressure. A failure of the grille shutter device is determined based on the refrigerant pressure, which changes at a large rate according to the opening/closing of the grille shutter, enabling failure determination with accuracy in a short time period.

摘要： A system for controlling fuel metering for a multi-cylinder internal combustion engine having a feedback loop which has an adaptive controller and an adaptation mechanism coupled to said adaptive controller for estimating controller parameters .theta.. The adaptive controller calculates a feedback correction coefficient using internal variables that include the controller parameters .theta., to correct a basic quantity of fuel injection to bring a detected air/fuel ratio to a desired air/fuel ratio determined earlier from the detected air/fuel ratio by a dead time d'. The dead time d' is properly determined to be corresponding to a time k at which the air/fuel ratio is detected. Alternatively, the dead time may be determined to be longer than the proper value to eventually improve vehicle drivability, or determined to be shorter than the proper value to compensate for insufficient fuel adhesion correction.

摘要： A control system for an internal combustion engine has an air-fuel ratio sensor arranged in the exhaust system. An air-fuel ratio feedback control carried out based on an output from the air-fuel ratio sensor such that an air-fuel ratio of an air-fuel mixture supplied to the engine is converged to a desired air-fuel ratio is selected between a high-response feedback control using an adaptive controller of a recurrence formula type and a low-response feedback control with a lower response speed than a response speed of the high-response feedback control. Operating conditions of at least one of the engine and an automotive vehicle on which engine is installed are detected. It is determined whether or not the engine is in an unsteady operating condition in which combustion of the engine undergoes a variation, based on detected operating conditions of at least one of the engine and the vehicle. The low-response feedback control is selected at least when it is determined that the engine is in the unsteady operating condition.

摘要： A control system for an internal combustion engine includes a canister for adsorbing evaporative fuel generated in the fuel tank, a purging passage extending between the canister and the intake system, for purging evaporative fuel into the intake system, and a purge control valve for controlling a flow rate of evaporative fuel to be supplied to the intake system through the purging passage. Various sensors detect operating conditions of the engine, and an ECU controls the purge control valve according to detected operating conditions. An amount of fuel to be supplied to the engine is feedback-controlled by calculating a feedback control amount, based on an output from an air-fuel ratio sensor arranged in the exhaust system by using a controller of a recurrence formula type, and the amount of fuel to be supplied to the engine is controlled based on the calculated feedback control amount, such that an air-fuel ratio of an air-fuel mixture supplied to the engine is converged to a desired air-fuel ratio. An average value of the feedback control amount is calculated while the purge control valve is open. The purge control valve is controlled based on the calculated average value.
