  • Engine state-based control of software functions
    Patent number: 8392882
    Abstract: Systems and methods provide engine state-based control of software functions. In one implementation, a system is provided that includes an engine and an engine control module. The engine control module determines a state of the engine and stores the determined state as an engine state variable. The engine state variable is interpretable by a plurality of components.

  • Diagnostic system for high pressure fuel system
    Publication number: 20090139488
    Abstract: A diagnostic system for an engine is disclosed. The diagnostic system has a sensor configured to sense a parameter of the fuel pressurized by the engine, and to generate a signal corresponding to a value of the parameter. The diagnostic system also has a controller in communication with the engine and the sensor. The controller is configured to detect a positive change in the parameter of the pressurized fuel and to inhibit starting of the engine if the positive change is not detected.
