Abstract

PURPOSE: To improve the detecting responsibility of the low-amount flow by using a precession generator.
CONSTITUTION: A swirler 41 having several impellers which develops eddy from suction air, a precession generator 4 of a Venturi 42 in the down stream of the swirler, and a few eddy detectors 5 which detect an electric signal turned from an eddy period of the precession are provided in a suction pipe 3. The air suctioned by the precession runs against the eddy detectors 5 and a frequency signal proportional to the amount of engine suction air is put from the eddy detectors 5 into a control circuit 100, which controls a fuel injection valve 10 according to the output from a revolution frequency detector 12 to meter the fuel amount at a proper ratio to suction air amount. The injection of the valve is synchronized with the running of the engine. A few eddy detector 5 can improve the responsibility to detect the low- amount flow.
