Patent ID: RE39765

Claim:
A cooling system for an engine, the cooling system comprising: a first coolant line coupled to the engine; a heater element coupled to said first coolant line; a second coolant line fluidically coupled to said first coolant line at a first end and a second end, wherein said first coolant line and said second coolant line form a continuous closed loop; a quantity of coolant contained within said continuous closed loop; a radiator fluidically coupled to said second coolant line between said first end and said second end; a water pump fluidically coupled within said first coolant line and rotatably coupled to said engine; a water motor fluidically coupled to said second coolant line between said first end and said second end; a fan coupled to said water motor,said fan rotating to cool said radiator as a function of the flow rate of said quantity of coolant through said water motor; a valve fluidically coupled to said second coolant line, said valve having an open position and a closed position, said closed position preventing flow of said quantity of coolant through said second coolant line and said open position allowing flow of said quantity of coolant through said second coolant line; a pump control coupling coupled to said pump, said pump control coupling controlling the rotational rate of said water pump and said water pump impellers to pump said quantity of coolant through said second coolant line; a belt coupled to said crankshaft pulley and said pump control coupling; at least one temperature sensor capable of measuring engine operating temperature; and a controller electrically coupled to said valve and electrically coupled to said speed control coupling and electrically coupled to said at least one temperature sensor, said controller controlling the actuation of said valve and controlling the rotational rate of said speed control coupling as a function of said measured engine operating temperature.
