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

Abstract

PURPOSE: To prevent air-fuel ratio change at warming up by controlling, only at the warming up time, the device, of which air-fuel ratio is controlled by the signal which is constituted by the number of rotation of engine and the components of exhaust gas, by the signals of the number of rotation.
CONSTITUTION: An actuator 9, which controls bleeding air ratio by its opening or closing motion, is provided in the main and slow air bleeds of the carburetor 2. The rotation number sensor 8, the exhaust gas sensor 12, and the water temperature sensor 13 are provided in the engine 1 and the suction and exhaust pipes 3, 4, and the signals from each of them are fed to the control circuit 10. Then, when warming up at the temperature below a predetermined temperature, the actuator 9 is controlled only by the signals from the rotation number sensor 8 by the water temperature sensor 13. The control is effected by the difference between the ratio of the change of rotation and the target value. In the operation range besides the case mentioned above, it is controlled only by the gas sensor 12.
