Abstract

PURPOSE: To optimize an air-fuel ratio by constracting a mechanism to vary a control constant in compliance with an driving condition, in a control equipment which determines an amount of fuel injection according to a quantity of an intake air.
CONSTITUTION: An air intake pipe 5 of an engine 1 is provided with an air cleaner 2, an air flow meter 3, a screw valve 7, a bypass port 8, a bypass passage 10 fitted with a control valve 10 and a fuel injection valve 6. A negative pressure pipe 16 provided with a fixed pressure valve 17 and an ambient air inlet pipe 18 with a pulse electromagnetic valve 19 is connected to a negative pressure working chamber 15 partitioned by a diaphragm 13 of a control valve 11. Then, an electromagnetic valve 19 and an injection valve 6 is controlled by a computer 20 where signals of a sensor 24 for number of revolution and a water temperature sensor 25 is given as an input. The computer 20 is composed of a micro processor 21, a memory 22 and an interface 23, and a proportional and an integral constant is varyed in accordance with a driving condition.
