Claims

[Scope of utility model registration request]

Two systems of fuel pipes supply fuel to the nozzle that injects fuel inside the bench lily, a carburetor that is set so that the air-fuel ratio is thinner than the stoichiometric air-fuel ratio when fuel is supplied from only one fuel pipe, and during acceleration etc. An internal combustion engine comprising means for supplying fuel from the other fuel pipe by opening a solenoid valve provided in the other fuel pipe in a region where large torque is required, and controlling the air-fuel ratio to near the stoichiometric air-fuel ratio. In the fuel supply control device, means for applying a control signal whose duty ratio gradually increases to the solenoid valve when the condition for opening the solenoid valve is satisfied, and means for applying a control signal to the solenoid valve that gradually increases the duty ratio when the condition for opening the solenoid valve is no longer satisfied. A fuel supply control device for an internal combustion engine, comprising means for applying a control signal whose duty ratio gradually decreases to the electromagnetic valve.
