Abstract
PURPOSE: To increase fuel during warming-up of an engine for providing the proper mixing ratio, by sending a temperature signal of the engine to a system wherein feedback of an air-fuel ratio is performed on the basis of the signal from an O2 sensor.
CONSTITUTION: Main- and bypass-fuel passages 15, 16 are provided between a float chamber 13 and a main nozzle 25. The bypass passage 16 is communicated with a solenoid valve 10 opened or closed by a control circuit 9 which receives the signal of an O2 sensor 8. The circuit 9 interrupts its feedback control under a certain temperature. The signal of a water temperature sensor 11 inside a cooling jacket 12 is inputted to the circuit 9. When an engine is started under a certain temperature, the circuit 9 opens the solenoid valve 10 to increase fuel.
