ABSTRACT:
A method and apparatus is disclosed for continuing the cooling of an engine, such as a turbo-charged equipped truck engine, at times when the engine temperature is elevated. In the illustrated form of the invention, the temperature of the engine is sensed. An engine control circuit bypasses the ignition switch at times when the sensed engine temperature is above a predetermined temperature and prevents the ignition switch from shutting off the engine under such conditions. The engine continues to operate, even though the ignition switch is off, until such time as the engine cools and the sensed temperature drops to the predetermined reference level. The predetermined temperature is adjustable to vary the temperature at which the engine is allowed to shut off. The apparatus includes optional indicator and override mechanisms.
