摘要： A control system for the internal combustion engine comprises means for detecting the flow rate of air sucked into the engine, as an electrical signal, means for detecting the number of revolutions of the engine, a sensor for sensing the oxygen concentration in the engine exhaust gas, a fuel injector for injecting fuel into the path of air sucked into the engine, in synchronism with the rotational angle of the engine at the required injection timing, and control means for controlling the fuel injection timing of the injector on the basis of the air flow rate signal from the air flow rate detector means, the number-of-revolutions signal from the number-of-revolutions detector means and the air-fuel ratio signal from the oxygen sensor. Under the normal operating conditions, the control means stores in a register the air flow rate signal, the number-of-revolutions signal and injection time at a given time point; judges that the signal from the oxygen sensor is within the level corresponding to the theoretical air-fuel ratio during a period longer than the air-fuel ratio transmission delay time of the fuel injector and the oxygen sensor; calculates the air-fuel ratio from the air flow rate signal, the number-of-revolutions signal and the injection time stored in the register; and stores in a memory an air-fuel ratio correction factor which is the ratio between said calculated air-fuel ratio and the initial air-fuel ratio stored already. These processes are repeated a number of times. Under the special operating conditions, the control means reads out the air-fuel ratio suitable for a particular special operating condition and controls the injection time on the basis of the air-fuel ratio obtained by correcting the read-out air-fuel ratio by the air-fuel ratio correction factor.

摘要： A method of controlling an internal combustion engine employs a microcomputer to control the fuel supply to the engine as well as the ignition timing thereof on the basis of measurement of the air quantity fed to the engine. For measuring the air quantity charged to the engine with high accuracy, the intake air flow fed to the engine is sampled in synchronism with the pulsating variation thereof. A value obtained by averaging the sampled values is used as the intake air quantity on the basis of which the fuel supply and the ignition timing are arithmetically determined.

摘要： A method and a system for engine control are disclosed. Electrical signals representing the engine operating conditions are detected, which electrical signals, together with the control data stored in a memory, are used to calculate a correction factor for correcting the control data for controlling the engine, where the correction factor is stored in a volatile memory, thus controlling the engine on the basis of the control data corrected by the correction factor. The correction factor stored in RAM is transferred to a non-volatile memory under predetermined conditions. Even if the voltage applied to RAM is reduced to a level lower than the storage ability of RAM, resulting in the loss of the stored data, the correction factor stored in EAROM is transferred back to RAM upon restoration of a normal voltage at RAM.
