IPC: F02D41/04
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To presume the change with the lapse of time of an air-fuel ratio sensor and correct an output therefrom. SOLUTION: When the feed of fuel to an engine is stopped, a rise time in which an output signal from an air-fuel ratio sensor attains a measurement stop threshold after the output signal exceeds a measurement start threshold is measured. During the use at an initial stage of the air-fuel ratio sensor, the measuring rise time is stored at a ring buffer in a first memory region and an average value of the number (n) if rise times or a standard deviation is calculated and stored at steps 18 and 19. Meanwhile, during presumption of the change with the lapse of time of the air-fuel ratio sensor, the measuring rise time is stored in a second memory region and an average value of the number (n) of rise times or a standard deviation is calculated and stored at steps S25 and 26.  During presumption of a change with the lapse of time, an air-fuel ratio λ is corrected by a correction factor KS set based on the average values or the deviation DTsigm of the standard deviations stored in the first and second memory regions. Based on a corrected air-fuel ratio λ, feedback control of an air-fuel ratio is effected at steps S21-24.

Filed: 1982-12-28
Abstract: PURPOSE:To reduce the power consumption of a logical circuit consisting of complementary insulating gate type field effect transistors (FET), by providing a means for applying a bias voltage between the substrate and source of at least one FET in the logical circuit. CONSTITUTION:When a reverse voltage is applied between the substrate and source of the complementary insulating gate type FET constituting the gate circuit composed of an inverter 8, the threshold voltage of the FET rises apparently.
