Abstract
PURPOSE: To work for stabilization of the engine rotation at the feed-back starting time and for optimum feed-back control by level shifting one of two comparison reference voltage for the exhaust gas sensor signals at the time of feed-back control starting and down time.
CONSTITUTION: When at the feed-back starting time and down time Vref1 of two comparison reference voltage Vref2, Vref1 is level shifted by such a portion as VP, at the moment of feed-back starting and until the internal impedance R of the sensor 3 becomes smaller compared with resistance RS the low level of electromotive force VS of the sensor 3 so big as about 100W400mV and the correction can be made lest biased feed-back control should be done. Like this, in a fixed period T1 from a time t1 until the sensor 3 generates the stabilied output, by controlling the level of the reference voltage Vref1 the optimal feed-back control corresponding to the activation speed of the sensor 3 can be made possible.
