摘要： A method for controlling mode transitions, such as from stratified to homogeneous mode, in a direct injection engine adjusts an intake manifold outlet control device, such as a cam timing, to rapidly control cylinder fresh charge despite manifold dynamics. In addition, a coordinated change between an intake manifold inlet control device, for example a throttle, and the outlet control device is used to achieve the rapid cylinder fresh charge control. In this way, engine torque disturbances during the mode transition are eliminated, even when cylinder air/fuel ratio is changed from one cylinder event to the next.

摘要： A direct injection fuel injector and method of operation wherein high fuel pressure exerting an opening force on an injection valve is slightly overbalanced by a return spring tending to close the valve. A first solenoid acts to open the valve against the excess return spring force and a second solenoid acts to close the valve when the first solenoid is de-energized. Rapid valve closing is provided by energizing the second solenoid before de-energizing the first solenoid, the force of the second solenoid when the valve is open being insufficient to overcome the force of the first solenoid holding the valve open. Thus, the second solenoid magnetic force is fully developed and quickly closes the injection valve when the first solenoid is de-energized. Various additional features are disclosed.

摘要： A handling device for setting the opening degree of the throttle valve to a desired degree even under conditions where the throttle lever is rotated to a full extent, and capable of immediately returning the throttle lever to a minimum opening degree (idling opening). The handling device has a main lever connected with one end portion of a cable and designed to pull the cable connected via the other end portion thereof with an actuating member, a movable pulley around which a portion of the cable in the vicinity of the one end portion is wound as a turn-around point, and a position adjustment mechanism comprising a sub-lever. The sub-lever is designed to move the movable pulley to a desired holding position so as to adjust a distance of pulling the cable.

摘要： A pedal side drive mechanism which is rotatable relative to a throttle shaft in both opening and closing directions is provided at one end of the throttle shaft. The throttle shaft opens and closes a throttle valve. A motor side drive mechanism, which is rotatable relative to the throttle shaft in both opening and closing directions, is provided at the other end of the throttle shaft. The pedal side drive mechanism and the motor side drive mechanism are able to be driven independently without interfering with each other, in both of the opening and closing directions of the throttle shaft. Accordingly, driving of the throttle can be performed using either the accelerator pedal or the motor, and functions including fail-safe measures or a limp home mode can be accomplished using a simple structure.

摘要： An engine control apparatus controls a throttle valve opening degree in response to a demand output of a driver. A target charged intake air amount of air taken into a cylinder per intake stroke is set in response to the demand output. Based on an air pressure generated at an upstream side of a throttle valve, the maximum actual charged intake air amount is set as a maximum value of the actual charged intake air amount taken into the cylinder per intake stroke. The target charged intake air amount is normalized by calculating a ratio of the target charged intake air amount to the maximum actual intake air amount. The throttle valve opening degree is set based on the normalized target charged intake air amount and an engine speed. Then, a signal for actuating the throttle valve is output to a throttle actuator so that the throttle valve has the set opening degree. Fuel injection amount is set based on the target charged intake air amount.

摘要： A throttle control system has two throttle opening sensors. When one sensor in a PID feedback control loop becomes abnormal, as sensed by monitoring the difference between outputs of the dual sensors, the use of sensor output for throttle feedback control is switched from the abnormal one to the other, normal one. Which one of the throttle opening sensors has become abnormal is determined by monitoring the intensity of electric current flowing to a DC motor which drives the throttle valve. Further, if an abnormality in the newly-used other sensor is determined, feedback control is continued based on an estimation of throttle opening calculated by using output of the sensor before its malfunction.

摘要： An engine, having an intake passage, a throttle valve arranged in the intake passage, and a fuel injector arranged in the intake passage for injecting fuel into the intake passage, comprises an air-flow control valve arranged in the intake passage between the fuel injector and the throttle valve. The air-flow control valve is controlled to close during the engine starting operation, and to open after the engine starting operation completes. The air-flow control valve has a valve element having an axis about which the element is rotatable when the valve is opened or closed. The rotational direction of the valve element is selected so that air flowing through the valve is guided by the valve toward the fuel injector when the air-flow control valve is controlled to an intermediate open position which is between the closed position and the full open position.
