An ECU generates operation command signals to the first to third control valves for closing or opening the same to bring the evaporative emission control system into a predetermined negatively pressurized state. The ECU is responsive to an output from a parameter sensor which detects at least one of vehicle speed, temperature within the fuel tank, and an amount of fuel within the fuel tank, for determining whether there is an abnormality in the evaporative emission control system, based upon an output from a tank internal pressure sensor. The output is obtained when the evaporative emission control system has been brought into the predetermined negatively pressurized state, when the value of at least one parameter detected by the parameter sensor falls within a predetermined range.

摘要： A method of controlling in a feedback manner the air-fuel ratio of an air-fuel mixture being supplied to an internal combustion engine of the type that vaporized fuel is supplied from a fuel supply system to an intake system thereof. The air-fuel ratio is controlled by the use of a correction value which varies in response to an output from an exhaust gas ingredient sensor, and the maximum or minimum value of which is limited to an upper or lower limit value. The pressure of the vaporized fuel in the fuel supply system is sensed, and at least one of the upper and lower limit values is set in accordance with the sensed pressure of the vaporized fuel. Further, the air-fuel ratio is controlled by the use of an average value of the correction value. The pressure of the vaporized fuel in the fuel supply system is sensed, and the calculation of the average value is inhibited when the sensed pressure of the vaporized fuel is higher than a predetermined value.

摘要： In a control system for controlling motor vehicles in such a manner that the drive force of the vehicle is determined by the accelerator pedal stroke and the vehicle speed, the fuel consumption is minimized by appropriately selecting the gear ratio of the power transmission system under each current operating condition. In particular, the present invention accounts for the slip ratio of the lock-up clutch as well as the transmission efficiency of the torque converter by noting the fact that the lock-up clutch operates under semi-tight conditions as well as under tight and loose conditions.

摘要： A device for detecting abnormality of the fuel supply system of an internal combustion engine inhibits supply of evaporative fuel to the intake passage when the air-fuel ratio correction coefficient becomes smaller than a predetermined value, and thereafter determines that the fuel supply system is normal when the air-fuel ratio correction coefficient increases above the predetermined value as a result of the inhibition of the supply of the evaporative fuel. The supply of the evaporative fuel to the intake passage is resumed after the determination that the fuel supply system is normal has been made. Determination of abnormality of the fuel supply system is inhibited after resuming of the supply of the evaporative fuel until the engine enters a predetermined operating condition in which the air-fuel ratio correction coefficient has increased. The determination of abnormality of the fuel supply system is permitted to be resumed, based on the air-fuel ratio correction coefficient when the engine has entered the predetermined operating condition.

摘要： A method of controlling fuel supply during beginning acceleration and acceleration after the interruption of fuel supply of an internal combustion engine is provided wherein a basic fuel supply amount which is determined in accordance with stable operating conditions of the engine is increased when it is detected that the throttle valve of the engine is opened from its almost closed position. The method comprises the steps of determining a reference value by adding a predetermined value of the throttle valve opening to a detected amount or value of throttle valve opening when it is detected that the throttle valve is opened from its almost closed position. The basic fuel supply amount is additionally correctionally increased if the correctional increase of the basic fuel supply amount, which was initiated upon detection of opening of the throttle valve, has not yet reached an end when the detected value of the opening of the throttle valve reaches the throttle valve opening reference value. Further methods of controlling fuel supply during acceleration are also provided wherein the additional correctional increase is a function of engine load or acceleration rather than throttle valve opening.
