Abstract

A control system to provide fuel flow to a motor cycle engine at a flow rate that matches the fuel demand of the engine. The motor speed of a turbine-style fuel pump may be varied, preferably by pulse width modulation (PWM) control. An Engine Control Module (ECM) determines desired fuel flow for any imposed operating condition or engine speed using a combination of engine input parameters plus voltage and flow calibration data maps on the particular fuel pump and motor in the engine, which calibration data maps may be revised periodically during the operating life of the fuel pump and motor. The pump speed may be determined by calibration and measurement of back EMF generated by the pump motor or by calibration and measurement of ripple in the current generated by the motor commutator. These electrical signals are inherent in the operation of the pump motor.
