摘要： An air-fuel ratio control method for an internal combustion engine, in which the air-fuel ratio of a mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio in response to output from an exhaust gas ingredient concentration sensor. When the engine is in a predetermined accelerating condition, fuel supply to the engine is increased. The rate of correction of the air-fuel ratio of the mixture by the feedback control is set to a smaller value when the engine is in the predetermined accelerating condition, than values to be set when the engine is in other operating conditions.

摘要： An air-fuel ratio control method for an internal combustion engine. The air-fuel ratio of an air-fuel mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio depending on operating conditions of the engine in response to output from an exhaust gas ingredient concentration sensor. The desired air-fuel ratio is settable to a value leaner than a stoichiometric air-fuel ratio when the temperature of the engine is above a predetermined reference value. The method comprises the steps of detecting a reduction ratio to which the transmission has been set, and changing the predetermined reference value of the temperature of the engine depending on the detected reduction ratio. The predetermined reference value of the temperature of the engine is set to a lower value as the reduction ratio of the transmission is smaller.

The air-fuel ratio of an air-fuel mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio dependent on operating conditions of the engine.

摘要： According to an air-fuel ratio control method, an amount of fuel supplied to an internal combustion engine is calculated by the use of an air-fuel ratio correction coefficient set according to an output from an exhaust gas ingredient concentration sensor. An average value of the air-fuel ratio correction coefficient is calculated. When a difference between an actual value of opening of an exhaust gas recirculation control valve and a desired value of same set in response to operating conditions of the engine is larger than a predetermined value, the calculation of the average value of the air-fuel ratio correction coefficient is inhibited, or alternatively, an averaging rate in the calculation of the average value is decreased.

摘要： An air-fuel ratio feedback control method for an internal combustion engine having an exhaust gas ingredient concentration sensor arranged in the exhaust passage and having output characteristics in approximate proportion to the concentration of an ingredient in exhaust gases from the engine, wherein when the engine is in a predetermined operating condition, the air-fuel ratio of an air-fuel mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio dependent on the predetermined operating condition of the engine, and when the engine is in a predetermined deceleration condition, the fuel supply to the engine is cut off. When the engine has shifted from an operating condition other than the predetermined deceleration condition to the predetermined deceleration condition, the desired air-fuel ratio is held at a value assumed immediately before the engine shifts from the operating condition other than the predetermined deceleration condition to the predetermined deceleration condition, for a predetermined time period after the shifting. The feedback control of the air-fuel ratio is started with the held value as an initial value of the desired air-fuel ratio when the engine has shifted to the predetermined operating condition. Preferably, the desired air-fuel ratio is held at a value substantially corresponding to a central value of air-fuel ratio after the predetermined time period has elapsed.

摘要： A method of detecting deterioration of an exhaust gas ingredient concentration sensor for use in controlling an air-fuel ratio of a mixture supplied to an internal combustion engine having an exhaust system in which the sensor is arranged. The sensor has an output characteristic approximately proportional to concentration of a specific ingredient in exhaust gases emitted from the engine. The air-fuel ratio is feedback-controlled to a desired air-fuel ratio by calculating an amount of fuel supplied to the engine by the use of a desired air-fuel ratio coefficient indicative of the desired air-fuel ratio and set in dependence on operating conditions of the engine, and an air-fuel ratio correction coefficient set in dependence on a value of an output from the sensor and the desired air-fuel ratio coefficient. A plurality of average values of the air-fuel ratio correction coefficient are calculated, respectively, when the desired air-fuel ratio falls within a plurality of predetermined ranges. The average values thus calculated are compared with each other. A degree of deterioration of the sensor is determined from results of the comparison. Further, a method of feedback-controlling the air-fuel ratio in the above-mentioned manner, in which the value of the output from the sensor is corrected in response to the degree of deterioration thus determined.

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.

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.
