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 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.
