Abstract

PURPOSE: Fuel injector having high accuracy and enable of stable operation obtained by improving the radiation efficiency of heating control power source while reducing the shielding effect of induced noise, electric resistance in wire furnace and the temperature fluctuation of it.
CONSTITUTION: Heating control section 6 of suction air meter is mounted on an air cleaner 1 having inlet 2, outlet 3 and a filter 4, while a flow detector 7 equipped with heating resistor 8 for detecting the flow speed, and compensating resistor 9 for detecting the air temperature is placed at the outlet 3. With such arrangement the Joule heat due to power transistor in the heating controller is transmited through an insulation board to the housing having the heating fuction and radiated into suction air. While since the flow detector 7 and the heating controller 6 are connected directly, there is no electric resistance of lead wire and it is not influenced by the heat of engine thereby the fluctuation of detecting accuracy is reduced.
