の燃料供給装置。 When starting the engine, the fuel supply amount is set to a starting setting value based on the predicted value of the intake air filling amount. After the engine starts, the fuel supply amount is determined based on the output value of the intake air amount detection means. In a fuel supply system for an engine equipped with a control means for performing normal operation control using a set value for normal operation calculated using a set value for normal operation, a determination is made to determine a transition point from the start control to the normal operation control. means and
Based on the determination by this determination means, immediately after the transition point, the normal operation setting is set by a correction amount that gradually decreases over time with the difference between the startup setting value and the normal operation setting value as the initial value. 1. A fuel supply device for an engine, comprising a correction means for correcting a value.
