Abstract
An apparatus for measuring an air flow intake of an internal combustion engine which comprises an air flow sensor for measuring the level of the air flow intake and an interface circuit for receiving an output signal from the sensor. The air flow sensor includes a current output circuit which outputs a current corresponding to the level of the air flow intake as the output signal of the sensor, and the interface circuit includes a current to voltage converter which converts the current from the sensor into a voltage signal and outputs it to an A/D converter included in a fuel injection unit.
