摘要： An air-fuel ratio in the lean range is detected by measuring a limiting current when oxygen diffused to a first electrode is pumped to a second electrode via a solid electrolyte. A stoichiometric air-fuel ratio is detected from electromotive force between first and third electrodes when oxygen is pumped from the first electrode to the third electrode. The invention is characterized by use of such three electrodes. Furthermore, an air-fuel ratio in a rich range is detected by either sending oxygen from the first electrode to the third electrode via the solid electrolyte and measuring a current when the electromotive force between the first and third electrodes is controlled to be constant, or measuring a current when the air-fuel ratio range is judged as "rich" from this electromotive force and the polarity of the impressed voltage at the time of lean detection is reversed.

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.

摘要： A fuel injection control apparatus for controlling the amount and the timing of fuel injection with the aid of a microcomputer includes a hot-wire type flow sensor for detecting an instantaneous intake air flow velocity within an intake air passage of an internal combustion engine. The output signal of the hot-wire type flow sensor is sampled at every predetermined crank angle or at every predetermined time point to be stored in a RAM. The time at which the instantaneous velocity of the intake air flow within the intake passage becomes maximum is detected. The fuel injection timing of a fuel injection valve disposed in the intake passage is so controlled that the fuel injection is terminated around the time point at which the instantaneous intake air flow velocity is maximum.
