摘要： An engine control apparatus is provided with a control unit in which a fuel supply quantity Q.sub.f or a ignition timing .theta..sub.i is corrected to maximize an evaluation parameter A=P.sub.i /(Q.sub.a /N) obtained on the basis of a suction air quantity Q.sub.a, an engine speed N and a mean effective pressure P.sub.i in a engine, or to maximize a parameter B=P.sub.i /P.sub.b obtained on the basis of a suction pipe pressure P.sub.b and the mean effective pressure P.sub.i, or to maximize a maximum pressure P.sub.max or a mean effective pressure P.sub.i for every combustion cycle, so that control is performed on the basis of the result of the above correction. The control unit also performs feedback control of the fuel supply quantity Q.sub.f and corrects the ignition timing. Further, the control unit performs feedback control in a predetermined load-operation range of the engine, and stops the feedback control and corrects the fuel supply quantity Q.sub.f out of said predetermined load-operation range of the engine.

摘要： A power train control system for an internal combustion engine of a motor vehicle. Opening of a throttle valve is electrically controlled in response to an accelerator pedal depression signal generated by an accelerator pedal position sensor and indicating depression depth of an accelerator pedal. A backup operation control of the engine is performed by controlling an auxiliary air flow which bypasses the throttle valve in dependence on the accelerator pedal depression signal upon occurrence of abnormality in a throttle valve control system. During the backup operation, a speed range shift pattern of an automatic transmission is changed over to a backup operation oriented pattern from a normal operation oriented pattern. The power train control system allows the motor vehicle to run even when a failure occurs in the throttle valve or a throttle control system in the fully closed state of the throttle valve.

摘要： A control apparatus for an internal combustion engine has cylinders each of which is provided with an exclusive fuel injection valve individually driven their openings. Each cylinder has a misfiring detecting means for detecting misfiring of that cylinder. The control apparatus includes a drive stopping means for stopping the driving of the fuel injection valve corresponding to a misfired cylinder so as to stop fuel supply to that misfired cylinder. The apparatus is further provided an air-to-fuel ratio sensor in the exhaust path of the engine so that when misfiring of the cylinder is detected, the fuel injection valves remain controlled through a feedback control where the openings of the normally fired cylinders are controlled in accordance with the air-to-fuel ratio signal outputted from the air-to-fuel ratio sensor in such a way that the apparent air-to-fuel ratio of the cylinders is given by an equation L=nLo/(n-p) where L is the apparent value of the air-to-fuel ratio of the cylinders when p cylinders are misfired, n is the number of cylinders, Lo is the air-to-fuel ratio of the cylinders when all of the cylinders are normally operating, and p is the number of misfired cylinders.
