Fuel supply control method for internal combustion engines immediately

Abstract

A fuel supply control method for electronically controlling the quantity of fuel being supplied to an internal combustion engine in synchronism with generation of pulses of a predetermined control signal, in response to a fuel increment gradually decreasing in value after termination of cranking of the engine. Immediately when the engine leaves a cranking state, an initial value of the fuel increment is set, which corresponds to a product obtained by multiplying the value of a fuel increasing coefficient decreasing in value as the engine temperature increases by the value of a coefficient being a function of the engine temperature. Subsequently, the thus set initial value of the fuel increment is decreased upon generation of each pulse of the above predetermined control signal until the thus decreased incremental value becomes equal to a value at which no substantial increase takes place in the fuel quantity being supplied to the engine.
