Claims

[Scope of utility model registration request]

In an engine fuel injection device that performs a warm-up fuel increase that increases the fuel injection amount when the engine temperature is low and an idle fuel increase that increases the fuel injection amount when the engine is idling, the engine has a first set rotation speed. and a second set rotation speed that is lower than the second set rotation speed.
Idle fuel increasing means that stops increasing the amount of idle fuel until the engine speed drops below a set speed, and increases the amount of idle fuel during other idle times;
Immediately after the engine is started when the engine temperature is below the set value, the intake air amount control means increases the intake air amount for a predetermined period of time so that the engine speed becomes equal to or higher than the first set speed. Engine fuel injection system.
