Fuel injection device

Abstract

Abstract PURPOSE: To permit feedback control of rotational frequency of an engine in idling by providing a microcomputer for compensating an amount of fuel injection on the basis of displacement of a controller in corresponding running condition. CONSTITUTION: In a memory 28 is stored map data 4 of correction factor K of fuel injection amount for difference ΔS between the initial position P of a control sleeve 11 and position of the control sleeve when rotational frequency in idling is corrected to a target one N. A secular change at a point of time is assumed as a correction amount ΔS for the position of the control sleeve, and a fuel injection amount q determined by the correction factor K 1 at this time is corrected to determine a quantity of electricity Q as the final fuel injection amount to make the output. This signal Q is sent to an actuator 29 and an optimum fuel for the operational condition of an engine at this point of time is injected. COPYRIGHT: (C)1981,JPO&Japio
