Abstract
A system is provided for controlling a temperature of oil in a power-plant operable to propel a vehicle. The system includes a heat-exchanger arranged relative to the power-plant. The heat-exchanger is configured to receive the oil from the power-plant, modify the temperature of the oil, and return the modified temperature oil to the power-plant. The system also includes a valve configured to direct the oil through the heat-exchanger during a warm-up operation of the power-plant such that the temperature of the oil is increased. The valve is also configured to direct the oil to bypass the heat-exchanger during a low load operation of the power-plant such that the temperature of the oil is increased. Additionally, the valve is configured to direct the oil through the heat-exchanger during a high load operation of the power-plant such that the temperature of the oil is decreased.
