Abstract

PURPOSE: To increase fuel during warming-up of an engine for providing the proper mixing ratio, by sending a temperature signal of a heater for a choke valve 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 18, 19 are provided between a float chamber 16 and a main nozzle 26. The bypass passage 19 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 circuit 9 is connected to a water temperature sensor 15 and a heater 13 for heating a bimetal 12 of a choke valve 24. When an engine is started under a certain temperature, the circuit 9 opens the solenoid valve 10 to increase fuel.
