  • Apparatus and method for automatic detection and avoidance of turbocharger surge on locomotive diesel engines
    Patent number: 6945047
    Abstract: The invention is an apparatus and method for detecting and responding to a surge event in a locomotive engine system including a turbocharger and a diesel engine. A sensor detects an operating parameter of the turbocharged engine and generates a signal indicative of the detected operatng parameter. An engine control system is responsive to the signal representative of a sensed operating parameter, or a determined changed in a sensed parameter, for controlling a plurality of operational controls of the diesel engine system. The engine control system modifies one or more operational controls of the diesel engine system when the signal indicates a surge event.

  • Apparatus and method for automatic detection and avoidance of turbocharger surge on locomotive diesel engines
    Publication number: 20040216457
    Abstract: The invention is an apparatus and method for detecting and responding to a surge event in a locomotive engine system including a turbocharger and a diesel engine. The apparatus includes a sensor for detecting an operating parameter of the turbocharger or the engine and generating a sensor signal indicative of the detected operating parameter. An engine control system is responsive to the sensor signal for controlling a plurality of operational controls of the diesel engine system. The engine control system modifies one or more operational controls of the diesel engine system when the sensor signal indicates a surge event. The invention also provides a method for detecting and controlling a surge event of a locomotive engine system including a turbocharger and a diesel engine operable at a plurality of discrete speeds.
