摘要： A method of controlling the quantity of supplementary air being supplied to an internal combustion engine having first and second control valves arranged, respectively, in first and second auxiliary air passages bypassing the throttle valve for on-off control of the opening areas of the respective auxiliary air passages. When the engine is operating in a particular operating condition, the first and second control valves are selectively actuated in response to the detected value of atmospheric pressure encompassing the engine in such a manner that the sum of the opening areas of the first and second auxiliary air passages increases as the detected value of the atmospheric pressure decreases. The engine is determined to be operating in the particular operating condition when it is in a cranking condition, when a predetermined period of time has not yet elapsed after the engine has got out of a cranking condition, or when the engine is in a warming-up condition. Preferably, the engine includes a third control valve arranged in a third auxiliary air passage bypassing the throttle valve, and adapted to increase the opening area of the third auxiliary air passage with a decrease in the engine temperature for controlling the supplementary air quantity to be supplied to the engine through the third auxiliary air passage to an appropriate value when the engine is operating in a warming-up condition at a predetermined reference atmospheric pressure.

摘要： An idling rpm feedback control method for controlling the quantity of supplementary air being supplied to an internal combustion engine, in a feedback manner, responsive to the difference between actual engine rpm and the desired idling rpm. When the engine rpm drops to a predetermined rpm being the upper limit of the desired idling rpm, the above feedback control is initiated. When the engine is decelerated with the throttle valve fully closed, and before the feedback control is started, the supplementary air quantity is controlled in decelerating mode in a predetermined manner while the engine speed drops from a predetermined rpm larger than the upper limit of the desired idling rpm to the same upper limit. In case deceleration is continued without disengagement of the power transmission means of the engine, even if the engine rpm drops below the above upper limit of the desired idling rpm, deceleration mode control of the quantity of supplementary air is continued until the power transmission means is disengaged.

摘要： A method for controlling the quantity of fuel being supplied to an internal combustion engine having a power transmission means for transmitting engine torque to vehicle wheels. The fuel quantity is controlled to required values after termination of a fuel cut operation which is effected at deceleration of the engine, by the use of increments set in synchronism with generation of pulses of a predetermined control signal. The state of engagement of the power transmission means is detected for a period of time after a transition of the operative state of the engine from the fuel cut operation to a normal operation wherein fuel supply is effected has been detected and before a predetermined number of pulses of the above predetermined control signal are generated. Among a plurality of predetermined groups of fuel increments having different fuel quantity increasing characteristics from each other, one group is selected which corresponds to the detected state of engagement of the power transmission means, to effect the above increasing of the fuel quantity by the use of the selected group of fuel increments.

摘要： A method for controlling the quantity of fuel being supplied to an internal combustion engine having a power transmission means for transmitting engine torque to vehicle wheels. The fuel quantity is controlled to a required value after termination of a fuel cut operation which is effected at deceleration of the engine, by increasing a quantity of fuel set at least as a function of intake pipe pressure by an increment which is set in synchronism with generation of pulses of a predetermined control signal. The increase of the fuel quantity is effected for a period of time after a transition of the operative state of the engine from the fuel cut operation to a normal operation wherein fuel supply is effected has been detected and before a predetermined number of pulses of the above control signal generated are generated, so long as the power transmission means remains in a disengaged state. Preferably, the above increase of the fuel quantity is effected only when the engine speed is lower than predetermined rpm. Further, the increase of the fuel quantity is prohibited while the power transmission means remains in an engaged state. Instead, while the power transmission means is in an engaged state, the fuel quantity is determined as a function of a value of intake pipe pressure which is set by subtracting a value dependent upon the engine speed from a detected value of intake pipe absolute pressure, until all the engine cylinders are supplied with fuel after the transition to the normal operation of the engine has been detected.

摘要： A fuel supply control method for electronically controlling the air/fuel ratio supply to an engine, in response to the output from means for detecting concentration of an ingredient in exhaust gases from the engine. When the engine is in a feedback control region, the air/fuel ratio control is effected by the use of a first coefficient, the value of which is variable in response to the output from the exhaust gas ingredient concentration detecting means, while simultaneously a mean value of values of the first coefficient applied during the feedback control operation is calculated for use as a second coefficient. The second coefficient and a predetermined value are used for control of the air/fuel ratio, in place of the first coefficient, respectively, when the engine is in a first one of the particular operating regions and when the engine is in a second one of same. Preferably, when there is a transition of the operating condition of the engine from one of the particular operating regions to the feedback control region, the air/fuel ratio control is initiated by the use of a second predetermined value other than the above predetermined value, preferably the above second coefficient, in place of the first coefficient. Further, preferably, when the engine is in an idling region as the above second particular operating region, the air/fuel ratio is further corrected by a correction variable corresponding to a preset voltage supplied from a variable voltage creating means.

摘要： In an exhaust system of the internal combustion engine, there are provided, in this order from upstream, a three-way catalyst, an adsorbent-catalyst containing at least zeolite in its composition and capable of absorbing hydrocarbons, an electrically heated catalyst containing at least platinum in its composition, and a catalyst containing at least palladium in its composition. The electrically heated catalyst can effectively purify low boiling-point HC of paraffinic hydrocarbon which has been desorbed from the adsorbent-catalyst after about 20 seconds from the start of the engine. On the other hand, the catalyst can effectively purify high boiling-point HC of aromatic hydrocarbon which has been desorbed from the adsorbent-catalyst after about 80 seconds from the start of the engine. When the catalyst is an electrically heated catalyst, it is energized after the energization of the other electrically heated catalyst is ended and the supply of electric power can hence be minimized.
