Abstract

PURPOSE: To perform appropriate operation of feedback control, by applying the mapping of duty ratio operating the fuel control of a carburetor with rotary speed and intake negative pressure further correcting the mapping in accordance with operating condition.
CONSTITUTION: A carburetor 6 is provided with correction, slow and main solenoid valves 6, 8, 9, and they are open-close controlled by a controller 1. The controller 1 stores reference values of intake negative pressure and rotary speed by the method of mapping, and its reference signal controls the slow and main solenoid valves 8, 9. When signals of sensors 10, 12, 13 for negative pressure, rotary speed, water temperature as an actually measured value and of a throttle switch 14 are input to the controller, the memory map is corrected, and its correction signal controls the correction solenoid valve 6 to perform the supply of correction fuel.
