Fuel injection quantity control system for general-purpose engine

摘要

A fuel injection control system corrects the amount of fuel injected by fuel injection valves toward an increased side when an acceleration state resulting from operation of a throttle occurs. An acceleration state determiner determines that a state is an acceleration state based on a change in throttle valve opening degree, and inputs a signal inducing fuel-amount-increase correction to an acceleration corrector. When a considerable change in the throttle valve opening degree occurs a predetermined number of times or more before a certain time period expires, determination of the acceleration state is stopped until a predetermined time period elapses.
