Air Flow Meter/Sensor: Description and Operation

DIGIFANT II




Air Flow Sensor

The air flow sensor measures the amount of air entering the intake manifold and sends a voltage signal to the control unit.

Intake air opens the air flow sensor flap which actuates the potentiometer to determine the voltage signal. This signal and the engine speed information supplied by the Hall sender are used as the principal inputs for the determination of fuel injector opening duration and ignition timing points

A compensation flap connected to the air sensor dampens sudden movements of the air sensor flap due to oscillations of the intake air.
