Abstract
PURPOSE: To try the air fuel ratio compensation at the beginning of acceleration, by controlling with a control valve in accordance with engine temperature, providing fuel returning path on the way of fuel path to connect to the first, the second ports in the pump cylinder chamber and an accelerating nozzle.
CONSTITUTION: With depressing an accelerator pedal, a piston element goes down, gasoline fuel is discharged towards the accelerating nozzle 21 from the first and the second outlet ports 17, 18. When engine cooling water temperature is lower than the prescribed value, a solenoid valve 29 is shut to close the fuel returning path 26, when the engine cooling water temperature is higher than the prescribed value, the solenoid valve 29 is opened to return some of fuel from the second outlet port 18 to the float chamber 8. When the piston element 10 exceeds the first outlet port 17, the fuel is discharged toward the accelerating nozzle 21 from only the second outlet port 18, however also in this case, being controlled with the solenoid valve 29. Consequently air fuel ratio compensation at the accelerating may be carried out
