  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To improve exhaust gas purifying capacity by setting the proportional allotment in the thickening direction in the control signal to compensate fuel supplying rate different from that in the thinning direction.
CONSTITUTION: The integral circuit is constituted of the operational amplifier 8, the condenser C1, and the resistances R1, R2. The switching signal generating circuit 9 is triggered by rising and falling of the deviation signal S5, and sends out the switching signals S6 each of which lasts for the different length of time. The switching circuit 10 stays on while the switching signals S6 being applied. The integral circuit produces the control signal S3 with different proportional allotments in the thickening direction and the thinning direction.
