摘要： An intake air control system for an engine having an air intake passage, a throttle valve in the intake passage and an intake valve for selectively opening and closing communication between the intake passage and a cylinder. The control system determines target intake passage pressure and target intake air amount in accordance with engine operating conditions. A target throttle opening is set in accordance with both the target pressure and the target intake air amount. The throttle valve is then driven to the target opening. Intake passage pressure is detected and a target intake valve open/close timing is determined in accordance with both the detected intake passage pressure and the target intake air amount. The intake valve is then driven in accordance with the target open/close timing.

摘要： When an air conditioner is turned on during homogeneous operation, an equivalence ratio correction factor &Dgr;&phgr; is increased sharply and suddenly in such a manner as to show a jump for thereby increasing an engine output torque, and thereafter is decreased gradually with increase of a cylinder intake air quantity, whereby to maintain the engine output torque constant. However, when switching to a homogeneous mode occurs in the middle of the above control, switching to proper torque correction is not carried out at the time of a homogeneous combustion mode, i.e., torque correction by the use of ignition timing but the torque correction by the equivalence ratio correction factor &Dgr;&phgr; continuously. By this, in contrast to the case in which the torque correction is switched to one that is carried out by the use of ignition timing correction quantity, a sharp and sudden variation of engine output torque can be prevented. In the meantime, after completion of the torque correction by the above mentioned control, the torque correction at the time of the homogeneous combustion mode is carried out by ignition timing correction. Further, when the combustion mode is switched to stratified combustion during execution of torque correction by ignition timing correction at the time of the homogeneous combustion mode, the torque correction is switched to one that is carried out by the use of the equivalence ratio correction factor simultaneously with switching of the combustion mode.

摘要： A cylinder direct-injection spark-ignition engine using at least a homogeneous combustion mode where early fuel-injection on intake stroke produces a homogeneous air-fuel mixture and a stratified combustion mode where late fuel-injection on compression stroke produces a stratified air-fuel mixture, is equipped with an electronic engine control unit connected to an electronic fuel injection system, an electronic spark-timing control system, and an electronically-controlled throttle valve. The control unit permits switching to a homogeneous combustion mode and changes the manipulated variable for engine torque correction to a spark-timing correction quantity, immediately when the demand for switching from stratified to homogeneous combustion mode occurs during a high-response torque correction. When the demand for switching from homogeneous to stratified combustion mode occurs during the high-response torque correction, switching to the stratified combustion mode is inhibited for a brief time duration until a required torque correction value reaches a predetermined criterion to continue the high-response torque correction based on the spark-timing correction quantity.

摘要： In an engine comprising a fuel vapor purge mechanism which mixes fuel vapor from a fuel tank with the intake air of the engine after fuel vapor has been adsorbed by a canister, a uniform fuel-air mixture and a stratified fuel-air mixture are selectively produced. When the engine is running with a stratified fuel-air mixture, purge of fuel vapor is prohibited. On the other hand, when the fuel vapor adsorption amount in the canister has reached a predetermined value, the engine is forcibly run with a uniform fuel-air mixture and purge of fuel vapor is performed, In this way, the fuel vapor adsorption amount in the canister is prevented from becoming excessive.

A throttle opening is controlled depending on both the compensated internal pressure and the desired intake-air quantity. Also, the intake valve open timing and the intake valve closure timing are controlled depending on both the compensated internal pressure and the desired intake-air quantity.

摘要： A reference steering angle achieved when the steering operation quantity is sustained at a constant value is calculated in correspondence to the steering operation quantity. A decision is made as to whether the vehicle is in a turn-contracting state, in which the direction of a steering operation matches the direction of a change made in the steering operation or a turn-expanding state in which the direction of the steering operation is opposite from the direction of the change made in the steering operation. If the vehicle is determined to be in a turn-contracting state, the target steering angles for the front wheels and the rear wheels are calculated by correcting the reference steering angle so as to achieve a smaller steering center elevation angle. If, on the other hand, the vehicle is determined to be in a turn-expanding state, target steering angles for the front wheels and the rear wheels are calculated by correcting the reference steering angle so as to achieve a larger steering center elevation angle. The steering angles at the front wheels and the rear wheels are adjusted independently of one another so as to match the steering angles with the target steering angles thus calculated.
