ABSTRACT:
The airflow rate through the induction tube of an internal combustion engine is measured by a first transducer which delivers a set point signal to a control amplifier. The amplifier also receives a feedback signal from a second transducer which monitors the position of a servo-motor controlling the quantity of fuel metered out to the engine. The feedback loop maintains a desired fuel-air ratio and includes provision for calibration and adjustment.
