  • Patent number: 8869523
    Abstract: A control system for use with a machine having an engine is disclosed. The control system may have a cooling circuit, a heat exchanger associated with the cooling circuit, and a sensor configured to generate a signal indicative of a temperature of the cooling circuit. The cooling system may also have a fan mechanically driven by the engine to direct air through the cooling circuit, and a controller in communication with the sensor and the engine. The controller may be configured to adjust a speed of the engine based on the signal.
    Type: Grant
    Filed: April 14, 2011
    Date of Patent: October 28, 2014
    Assignee: Caterpillar Inc.

  • Patent number: 6729270
    Abstract: The present invention relates to a cooling circuit for a work machine that provides increased cooling capacity of a radiator without increasing the physical size of the radiator. The cooling circuit includes a jacket water pump, a jacket water portion of an engine and a radiator fluidly coupled to the circuit. A first powertrain oil cooler is fluidly coupled to the cooling circuit between the jacket water pump and the jacket water portion. A second powertrain oil cooler is fluidly coupled to the cooling circuit between the jacket water portion and the radiator. Positioning of the powertrain oil coolers in this manner increases the temperature differential between ambient air and coolant entering the radiator, therefore increasing cooling capacity of the radiator.
