  • Control Of The Air-Fuel Ratio Of Carburetors (AREA)

Abstract

PURPOSE: To totally control an air-fuel ratio of mixture, and always perform an accurate operation, by controlling a quantity of air bleed of the carburetor and a quantity of bypass air, detoured in the carburetor, with a signal of every operational state of the engine.
CONSTITUTION: In an engine 18, linking an intake and exhaust pipe 19, 18, are provided a throttle valve opening degree sensor 14, 15, an air quantity sensor 17, an intake suction sensor 10, a rotation sensor 12, a water temperature sensor 13 and an O2 sensor 3, and a signal from each sensor is inputted to a controller 1. In addition, an output signal of the controller 1 makes a feed-back control of slow and main solenoid 8, 9, for controlling a quantity of air bleed of a carburetor 7, a correction solenoid 6, for controlling a carburetor fuel path, and a bypass solenoid 16, for supplying only air with a detour made in the carburetor. And an air-fuel ratio of the mixture, supplied to the engine 18, is made accurate in accordance with a state of operation.
