  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To perform feedback control for a theoretical air fuel ratio, by providing a fuel injection valve in an intake passage at the downstream side of a carburetor and controlling the injection depending on the quantity of intake air and the oxygen concentration of exhaust gas.
CONSTITUTION: The carburetor 1 comprises a choke valve 3, a throttle valve 5, a main fuel passage 8 for connecting a float chamber 6 to a main nozzle 10 and a slow fuel passage 11 for connecting the float chamber 6 to a slow port 13 and an idle port 14. The carburetor 1 is installed at an intake passage 2. The quantity of fuel injected through the fuel injection valve 26 is controlled by a controller which receives signals from an intake air quantity sensor and an oxygen concentration sensor for detecting the oxygen concentration in the exhaust gas. The fuel injection valve 26 is provided under the carburetor 1. The air fuel ratio of a mixture supplied from the carburetor 2 is compensated by the fuel injected through the injection valve 26 to obtain the theoretical air fuel ratio as a whole.
