ABSTRACT:
An electronic controlled carburetor includes sensors for sensing engine speed, intake air pressure and water temperature. An arithmetic unit digitally processes output signals from the sensors and generates signals for controlling the air-fuel ratio of a mixture supplied to an engine on the basis of the output signals from the sensors. The carburetor system includes means for sensing atmospheric pressure and intake air temperature, and means for adjusting at least one of the amount of intake air of the engine and the amount of fuel. The arithmetic unit digitally processes the output signals from the atmospheric pressure and the intake air temperature sensing means to thereby produce a signal representing air density change and automatically controls at least one of the amount of intake air and fuel on the basis of the air density changing signal, to thereby control the air-fuel ratio of the mixture with higher accuracy.
