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

Abstract

PURPOSE: To improve fuel economization by shutting off a fuel under the so- required condition and incrementing the fuel according to the shut-off interval, thereby avoiding a creation of noxious constituents of exhaust gas at start of fuel supply.
CONSTITUTION: When a throttle valve is completely closed and a rotation speed exceeds a specific value, B=1 is set at a step 1024 to perform cut-off of a fuel. If a step 1013 verifies that the throttle valve is not completely closed and the rotation speed is under the specific value, a step 1015 checks for B=1 or not, that is, determines whether it is the moment when a fuel injection after the fuel cut-off should be started again, or not. If should, a step 1016, a next step of the step 1015 reads an increment ratio r0 to a value A representing the interval of the fuel cut-off and sets r=r0. And a step 1017 indicates B=0 which tells that a fuel is not being cut off.
