摘要： A fuel supply control system for an internal combustion engine comprises deceleration detecting device for detecting a predetermined decelerating condition of the engine, and fuel supply decreasing device for decreasing the supply of fuel to the engine when the predetermined decelerating condition is detected by the deceleration detecting device. A first counting device starts to count a first predetermined time period when the high-load detecting device detects that the engine has left the predetermined high-load condition. An inhibiting device inhibits the fuel supply decreasing device from operating when the deceleration detecting device detects the predetermined decelerating condition of the engine before the first counting device completes counting the first predetermined time period. A second counting device counts a second predetermined time period while the high-load detecting device is detecting the predetermined high-load condition of the engine. The first counting device starts to count the first predetermined time period when the second counting device has completed counting the second predetermined time period. An intake air increasing device increases the amount of intake air supplied to the engine while the inhibiting device is operating.

摘要： A method of controlling the air-fuel ratio of a mixture of fuel supplied to an internal combustion engine. Feedback control is effected to response to an output from an exhaust-gas concentration sensor to bring the air-fuel ratio to a predetermined value when the engine is in a predetermined medium-load operating region. It is determined whether or not the engine is in a predetermined high-load operating region in which the feedback control is interrupted for bringing the air-fuel ratio to a value smaller than the predetermined value, and whether or not the engine is in a predetermined low-load operating region in which the feedback control is interrupted for bringing the air-fuel ratio to a value larger than the predetermined value. The feedback control is effected even when the engine is in the predetermined low-load operating region, if the engine continually stayed over a first predetermined time period in the predetermined high-load operating region, and has shifted to the low-load operating region within a second predetermined time period after leaving the predetermined high-load operating region.

摘要： A fuel supply control system for an internal combustion engine having a throttle body, and a fuel injection valve arranged in an intake manifold upstream of the throttle body for supplying fuel to all cylinders. An air throttle valve has a valve body having a notched opening formed therein and disposed to be opposite the nozzle of the fuel injection valve to increase the flow speed of intake air in the vicinity of the nozzle when the air throttle valve is fully closed. An electronic control unit controls the fuel injection valve in response to operating conditions of the engine. The electronic control unit causes the air throttle valve to be fully closed when a predetermined low rotation-speed operating condition of the engine, in which at least the rotational speed of the engine is lower than a predetermined value, is satisfied. The predetermined value of the rotational speed of the engine is set such that the lower the atmospheric pressure the smaller the predetermined value.
