  • Apparatus for maintaining a diesel engine at a ready to start temperature
    Patent number: 4421075
    Abstract: Apparatus for maintaining a diesel engine at a ready to start temperature includes a sensor responsive to the falling of the engine block temperature to a predetermined low value to actuate the starter for up to a predetermined maximum period of time and to actuate the fuel supply. A sensor responds to the attainment of a predetermined oil pressure corresponding to an engine running condition to de-actuate the starter and continue the actuation of the fuel supply to continue running of the diesel engine. The temperature sensor responds to the raising of the engine block temperature to a predetermined high value to de-actuate the fuel supply and thereby stop the diesel engine.
