PURPOSE:To achieve smooth operation and to save fuel consumption, by providing a throw-control solenoid valve for regulating bleed air flow in throw fuel system and main control solenoid valve for regulating bleed air flow in main fuel system. CONSTITUTION:A throw-control solenoid valve 13 will open/close an auxiliary air bleed 22 to regulate bleed air flow in throw fuel system. Main control solenoid valve 14 will open/close an auxiliary air bleed 23 to regulate bleed air flow in main fuel system. A control circuit 15 will receive signals from various sensors for indicating the operational condition to control open valve function of said valves 13, 14. Consequently good air-fuel ratio control an be achieved over entire operational region resulting in smooth operation, saving of fuel consumption and reduction of noxious component in exhaust gas. |
