Abstract
PURPOSE: To improve characteristics of acceleration from low speed in such a way that driving current from an electromagnetic valve in the slow system is made larger than that in the main system by providing electromagnetic valves on the main and slow sides which are equal in the control current-opening angle characteristics.
CONSTITUTION: An electromagnetic valve 17 on the main side is installed on the main air bleed passage 15 of a carburetor 1, and an electrimagnetic valve 18 on the slow side is installed on the slow air bleed passage 16. At the same time as control current-opening angle characteristics of the both electromagnetic valves 17, 18 are equalized, driving is made by an electronic circuit part 22 to receive signals from an air-to-fuel sensor 21 of an exhaust pipe 20. And, the circuit part 22 is set to as to make driving current from the electromagnetic valve larger than that on the main side, so that it can make the connection specially favorable from the slow side to the main side.
