ABSTRACT:
An improved electronic control fuel injection system is disclosed wherein, during acceleration, fuel of a given amount is supplied to an engine which is commensurate with a sum formed of the amount of fuel to be burned with air in a combustion chamber, and an amount of fuel to be consumed so as to wet or moisten the inner surfaces of an intake port and the like which have been dried due to a prolonged interruption in the supply of fuel to an engine during a preceding deceleration condition. The fuel supplied to an engine through an injection valve operated by the disclosed fuel injection system at the beginning of acceleration immediately subsequent to the interruption of the fuel supply for a predetermined duration forms, with the incoming air, a desired air-fuel ratio, so that a mixture charge may be burned at the beginning of the acceleration without engine misfires occurring. The given amount of fuel supplied at the beginning of the immediately subsequent acceleration is supplied to an engine by a control circuit which forms a pulse output separately from the control-signal-generating circuit pulse output normally associated with a fuel injection system and thus does not resort to measures to increase the width of the pulses supplied from the control-signal-generating circuit. This ensures a smooth build-up of engine torque and prevents the imposition of shocks on an automobile, and results in an effective utilization of the first fuel supply pulse from the control-signal-generating circuit, immediately after the subsequent acceleration of an engine.
