Abstract
An apparatus for controlling a temperature of an engine by controlling the flow of a liquid engine coolant to a radiator is disclosed. The apparatus includes a thermostat having a thermally responsive valve for substantially blocking or opening the flow of coolant to the radiator to maintain the engine at or about a preferred engine operating temperature. Also included is a thermally activated actuator for opening the valve in response to an engine condition such as load or a need for power. The actuator is activated at a temperature different than the thermostat. A source of electro thermal energy is provided to motivate the actuator so the valve may be opened on demand. In one aspect the invention provides a method of controlling the temperature of the engine by opening the valve in response to engine monitoring.
