Abstract

PURPOSE: To make the required values in all areas of the engine at the optimum by making the suction air quantity and the number of rotation a function of fuel feed and by obtaining an output signal by which a fuel flow required to the engine can be given on table retrieving operation by the computer.
CONSTITUTION: Air is led from the air cleaner 10 to the engine through the Venturi 2 and throttle valve 3 in the carburetor during operation. Fuel fed from the float chamber 9 through the main jet 4 and slow jet 6 is mixed with air from the main air bleed 5 and slow air bleed 7 respectively, and is injected from the main jet 12 and idle hole 13 into the Venturi. At this time, a previously set table is retrieved by the computer CU according to the output of temperature sensing resistance 11 for the air flow detection and the valve of quantity of rotation, and signals for the required fuel flow corresponding to said detecting values are obtained to control the electromagnetic valves 14, 14.
