  • Systems and methods for controlling engine temperature
    Patent number: 8443775
    Abstract: A system for controlling temperature associated with an engine is provided. The system includes a first fluid circulating system, including a first fluid pump and a heat exchanger. The engine, the first fluid pump, and the heat exchanger are in flow communication. The system also includes an electric power source. The system further includes a second fluid circulating system, including a second fluid pump and a heating element. The engine, the second fluid pump, the heat exchanger, and the heating element are in selective flow communication. The system further includes a sensor associated with the engine, the sensor configured to sense at least one parameter and to generate a signal indicative of the at least one parameter. Moreover, the system includes a controller configured to control operation of the second fluid circulating system in response to the signal, and to control the heating and cooling of the engine.
