Abstract
In a process and apparatus for regulating the temperature of coolant in an internal combustion engine, a three way valve controls the relative quantity of coolant flowing through a radiator, and a by-pass line bypassing the radiator. The valve responds both to the absolute temperatures of the coolant in the by-pass line leaving the engine and the line leaving the radiator to adjust the relative flow through the lines. A control system monitors the temperature of the coolant leaving and entering the engine and controls the pump and fan speeds in the normal manner.
