Abstract:
An engine cooling system and method that will allow an engine cooling fan to be driven independently of the engine speed. The engine cooling fan is driven by the engine crankshaft, but includes an electronically controllable fan clutch between the fan and the crankshaft. A control module electronically controls the engagement of the fan clutch based upon engine and vehicle operating conditions. A water pump for pumping coolant through the engine cooling system may also be driven by the crankshaft of the engine, but with an electronically controlled pump clutch between the engine crankshaft and the water pump.
