ABSTRACT:
An oil cooling system to provide enhanced thermal control for internal combustion engines wherein the oil cooling system of the present invention works in conjunction with the standard oil lubrication circuit and typical liquid coolant system of an engine to maintain the engine temperature in a constant range even when operated in an environment with extreme thermal conditions for a prolonged period of time. The present invention detects when the oil temperature has exceeded a pre-determined range and sends the oil to a radiator with heat sinks and a fan for extracting the heat therefrom and dissipating it before recycling it back to the oil sump where it serves to lubricate and cool the heat-generating components it comes in contact with.
