ABSTRACT:
A fuel system for an engine has a source of pressurized fuel, a rail, and a plurality of fuel injectors. The fuel system also has a sensor to sense a parameter of the pressurized fuel, and a controller. The controller is configured to generate a flow control offset value indicative of a difference between the value of the parameter and a desired value for the parameter, and to control operation of the source in response to the flow control offset value when the sensor is determined to be functioning properly. The controller is also configured to store the flow control offset value in a memory of the controller when the sensor is determined to be functioning properly and to associate the flow control offset value with at least one operating condition of the engine. The controller is further configured to control operation of the source in response to previously stored flow control offset value when the sensor is determined to be malfunctioning.
