摘要： A throttle control apparatus serves to control a degree of opening of a throttle valve via an actuator. The throttle valve is provided in an air induction passage of an internal combustion engine. The throttle control apparatus includes a throttle opening degree sensor for detecting the degree of opening of the throttle valve. An engine operating condition detecting device is operative to detect an operating condition of the engine. A throttle opening degree estimating device is operative to estimate the degree of opening of the throttle valve on the basis of the operating condition of the engine which is detected by the engine operating condition detecting device. A memorizing means serves to memorize a corrective quantity. A corrective quantity updating device is operative to update the corrective quantity memorized by the memorizing device on the basis of a difference between an output value from the throttle opening degree sensor and an estimated value from the throttle opening degree estimating device. A control device serves to adjust a controlled quantity of the actuator in response to the output value from the throttle opening degree sensor and the corrective quantity memorized by the memorizing device to control the degree of opening of the throttle valve.

摘要： A throttle control apparatus includes an electrical drive unit for electrically driving a throttle of an internal combustion engine and a mechanical drive unit for driving the throttle through the operation of an accelerator by a driver. In the case where an abnormality is generated in the electrical drive unit, the driving of the throttle by the electrical drive unit is interrupted and the throttle is thereinstead driven by the mechanical drive unit. The mechanical drive unit is provided with a throttle opening angle control member. The throttle control apparatus further includes a torque control unit for suppressing an increase in output torque of the internal combustion engine in the case where a throttle opening angle is increased in the direction of an opening angle set by the throttle opening angle control member when the driving of the throttle by the electrical drive unit is interrupted.

摘要： An apparatus for controlling intake air flow rate in an internal combustion engine comprises a throttle valve disposed in intake air passage for swing movement to change a flow rate of air to be supplied to combustion chambers of the engine, a stopper portion to which the throttle valve is abutted so as to stop swinging thereof in a full closed portion thereof, a spring for continually urging the throttle valve towards the full closed position, a control unit for determining a desired opening degree of the throttle valve in accordance with requirements on the engine, an actuator for generating a driving force for swinging the throttle valve to the desired opening degree in accordance with a command signal from the control unit, and geared mechanism for transmitting the driving force from the actuator to the throttle valve. The geared mechanism includes a pair of gears, each having a gear tooth portion. The gears are able to engage with each other exclusively at such gear tooth portions. The gear tooth portion so extends that both of the gear tooth portions mesh with each other between full closed position and full open position of the throttle valve, and they are pushed out of mesh with each other over full open position of the throttle valve.

摘要： An apparatus for treating fuel vapor, such as in a motor vehicle fuel tank, by subjecting it to adsorption treatment to prevent its direct emission into the atmosphere. The apparatus according to the present invention comprises a fuel tank, a partitioning wall provided within the fuel tank to define a small fuel storage chamber within the fuel tank, a canister container housed in the small fuel storage chamber, the canister container storing therein a fuel adsorbing material. When fuel feeding takes place, feeding fuel is introduced into the small fuel storage chamber to cool the canister container. However, when the engine is operated, high temperature return fuel is introduced into the small storage chamber to heat the canister container thereby promoting the adsorbing and de-adsorbing action of fuel by the fuel adsorbing material.

摘要： Disclosed in an internal combustion engine control system for controlling at least one of the quantity of intake air and quantity of fuel supply, and to an internal combustion engine control system for controlling the air-fuel ratio of the mixture. The invention particularly relates to the control of the engine at a transition of operating condition. The former control system detects the change in one of the quantity of intake air and quantity of fuel supply and compensates the other, thereby controlling the engine by anticipation at a transition of control condition. The latter control system, as a first case, infers the mixture air-fuel ratio contributive to combustion so as to adjust fuel supply to the cylinder which is currently in the suction stroke, or, as a second case, infers the mixture air-fuel ratio in the same way as above so as to adjust the quantity of air taken in the cylinder which is currently in the suction stroke, both cases implementing the anticipation control so that the mixture air-fuel ratio is maintained within the prescribed range.

摘要： A vehicular constant-speed running system converges a vehicle speed control of a vehicle quickly to a target vehicle speed when the vehicle is set in a cruise control mode. The vehicular constant-speed running system includes a constant-speed running section for controlling a throttle opening independently of an accelerator opening to maintain a vehicle at a target vehicle speed. It also includes an initial opening setting section which, at the time of transfer by the constant-speed running section, sets the throttle opening before the transfer to an initial value at the time of the transfer if the throttle opening is in a region which is preset based on either the vehicle speed at the time of the transfer or a parameter correlated with the vehicle speed. If the throttle opening is not in this region, the initial opening setting section sets the same throttle opening to the upper limit and/or the lower limit of that region.

摘要： A control apparatus for electrically operating a throttle valve adapted to adjust the amount of air drawn into an internal combustion engine to adjust the position of the throttle valve. The position and operating condition of an accelerator pedal are electrically detected to generate a signal in accordance with the accelerator position to drive an actuator adapted to operate the throttle valve, and also a desired throttle position established by the signal, the detected actual position of the throttle valve and the operating condition of the accelerator pedal are suitably compared and examined, thus monitoring to see whether the detection of the accelerator position is not faulty, whether the throttle valve is controlled to follow the desired throttle position and so on and thereby performing a safe control by using a substitute desired position upon occurrence of a faulty condition. Also, during the period of acceleration/deceleration, a driving signal is generated to operate the throttle valve to suit the engine operating condition. Further, when the actuator steps out of synchronism, an evacuation control is performed.

摘要： A vaporized fuel control apparatus for an internal combustion engine. Fuel vapor formed in the fuel tank during the refuelling period is adsorbed to a refuelling canister and fuel vapor formed in the fuel tank during the engine running period is adsorbed to a running canister. The canisters are controlled in a manner that the amount of the fuel vapor discharged into the intake system of the engine from the refuelling canister is smaller than that of the running canister.
