<p>An apparatus is provided for controlling the temperature of an engine (28) based on a temperature control signal (20) related to an optimum engine temperature generated by an electronic control module (10) using an output signal from at least one sensor (14). A controller (22) generates an output signal (26) based on a temperature control signal (20) received from the electronic control module (10) and on a signal (24) proportional to the actual engine temperature received from an engine temperature sensor (14). The apparatus also includes an electronically actuated thermostat (24) including a valve (46) located within a coolant flow passageway (40) of the engine block (38) and a motor (44) electrically coupled to the controller (22) for controlling the valve (46).</p> |
