Abstract

See full text

A control system for a fuel supply module of an engine is provided. The control system includes a first fuel flow sensor in a fuel supply line which detects a first amount of fuel flowing through the fuel supply line and generates a first signal indicative of the first amount of fuel. The control system includes a second fuel flow sensor in the fuel return line which detects a second amount of fuel flowing through the fuel return line and generates a second signal indicative of the second amount of fuel. A controller receives the first signal and the second signal. The controller calculates a difference between the first signal and the second signal. The controller commands operation of the fuel supply module to supply a fuel flow to the engine independent of the engine speed, based on the difference between the first signal and the second signal.
