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.

Abstract: A rotary valve provides single point flow control of coolant within the cooling system of an internal combustion engine. The valve distributes coolant flow from the engine in predetermined flow modes to either 1) the radiator and heater simultaneously, 2) a bypass circuit only, 3) the heater only, or 4) the radiator and bypass simultaneously. The single-point coolant control results in advantages of shorter warm-up times, a lower pressure drop (reducing power consumption by the pump), reduced engine emissions and fuel consumption, improved cabin heater performance, and improved engine durability due to reduced thermal shocks to the engine components by virtue of more precise control of engine operating temperature.

Abstract: An apparatus for holding a heat exchanger core during a manufacturing process is disclosed. The core includes a first and second side support member disposed on opposite sides of an assembly of a plurality of interleaved tubes and fins and fluid manifolds on opposite ends of the tubes. The apparatus includes a pair of nested clamps. One clamp is disposed over the side supports and the second is disposed over the fluid manifolds. The clamps are easily placed over the core and easily removed after brazing.
