摘要： A fuel supply control system for an internal combustion engine, wherein when the engine is at idle, a correction value is determined based on a difference between a desired idling engine rotational speed and an actual engine rotational speed, and an amount of fuel to be supplied to the engine is corrected by the determined correction value. Correction value-changing means sets a rate of change in the correction value relative to a change in the difference to a greater value when the detecting means detects that the engine means is not engaged with the transmission of an automotive vehicle, and to a smaller value when the detecting means detects that the engine is engaged with the transmisison.

摘要： An evaporative fuel-processing system for an internal combustion engine has an evaporative emission control system. An ECU carries out negative pressurization of the interior of the evaporative emission control system, by opening a purge control valve and closing a vent shut valve, and determines presence/absence of leakage from the evaporative emission control system, based on a rate of decrease in negative pressure within the system, by closing a purge control valve. Before the negative pressurization, the interior of the evaporative emission control system is opened to the atmosphere, and during the open-to-atmosphere, a pressure state within the fuel tank is estimated based on a rate of change in an output from a pressure sensor which senses pressure within the evaporative emission control system. The ECU determines whether the evaporative emission control system is normal, based on the estimated pressure state.

摘要： A fuel injection control system for an internal combustion engine includes an ECU which carries out adherent fuel-dependent correction by calculating an amount of fuel to be injected into the intake passage such that a sum of a direct supply amount of fuel directly drawn into the combustion chamber of the engine without adhering to the wall surface of the intake passage out of a whole amount of fuel injected into the intake passage, and a carried-off amount of fuel carried off the wall surface of the intake passage into the combustion chamber out of fuel adhering to the wall surface of the intake passage is equal to a required fuel amount for the engine. The starting condition of the engine is detected by sensors, and operation of the adherent fuel-dependent correction control is limited during the starting condition of the engine. The carried-off fuel amount is set to a predetermined value, based on at least one operating parameter of the engine when the engine has shifted from the starting condition to the basic operating condition after starting.

摘要： A device for detecting abnormality of the fuel supply system of an internal combustion engine inhibits supply of evaporative fuel to the intake passage when the air-fuel ratio correction coefficient becomes smaller than a predetermined value, and thereafter determines that the fuel supply system is normal when the air-fuel ratio correction coefficient increases above the predetermined value as a result of the inhibition of the supply of the evaporative fuel. The supply of the evaporative fuel to the intake passage is resumed after the determination that the fuel supply system is normal has been made. Determination of abnormality of the fuel supply system is inhibited after resuming of the supply of the evaporative fuel until the engine enters a predetermined operating condition in which the air-fuel ratio correction coefficient has increased. The determination of abnormality of the fuel supply system is permitted to be resumed, based on the air-fuel ratio correction coefficient when the engine has entered the predetermined operating condition.

摘要： An evaporative fuel-purging control system for an internal combustion engine, which controls purging of a mixture of evaporative fuel from a fuel tank and air comprises a purge control valve arranged across a purging passage for controlling the flow rate of evaporative fuel from the fuel tank to an intake passage. The flow rate of evaporative fuel is detected and compared with a desired flow rate commensurate with an operating condition of the engine. The valve opening of the purge control valve is controlled in response to results of the comparison. The change rate of the valve opening is varied according to the concentration of evaporative fuel in the mixture. Specifically, the change rate is decreased as the evaporative fuel concentration is higher.

摘要： A control system for internal combustion engine installed in vehicle with automatic transmission which lowers the engine output torque for reducing the shock apt to be felt by the passengers of a vehicle equipped with an automatic transmission at the time of shifting gears. The clutch speed ratio between the transmission input and output shafts is calculated to compare with a first value. If the ratio goes beyond the first value, engine output torque is reduced by a first amount. Then the ratio is compared with a second value and if the ratio comes within the second value, the torque is further reduced by a second amount which is greater than the first amount. The ratio is continuously calculated and is again compared with a third value. When the ratio comes within the value, the torque is restored to the first reduction amount. The ratio is finally compared with the fourth value and if it comes within the value, the torque is fully restored to the initial state. Thus, the gear shift shock is avoided and as a secondary effect, clutch wear is reduced.

摘要： An intake air amount control system for an internal combustion engine includes a control valve for regulating the amount of intake air supplied through the intake pipe to the engine. An ECU determines the difference between a desired idling rotational speed of the engine and an actual rotational speed of same and feedback-controls the control valve by means of a control amount responsive to the determined difference such that the actual rotational speed becomes equal to the desired idling rotational speed. The ECU learns a reference value of the control amount by calculating an average value of values of the control amount applied during the feedback control. The ECU inhibits the learning of the reference value of the control amount when the difference between atmospheric pressure and absolute pressure within the intake pipe is smaller than a predetermined value.

摘要： An air-fuel ratio feedback control method for an internal combustion engine, in which when the engine is operating in a feedback control region, the air-fuel ratio of an air-fuel mixture being supplied to the engine is controlled by the use of a correction coefficient varying in response to the output of an exhaust gas ingredient concentration sensor arranged in the exhaust system of the engine. When the engine has shifted to a predetermined high load region within the feedback control region, in which the rate of change in values of an engine operating parameter is larger than a predetermined value, the air-fuel ratio feedback control is effected by the use of a first average value of the correction coefficient, calculated when the engine is in the predetermined high load region. When the engine has shifted to a second predetermined region within the feedback control region other than the predetermined high load region, the feedback control is effected by the use of a second average value of the correction coefficient, calculated in the second predetermined region, in a manner different from that of calculating the first average value.
