  • Method and apparatus for operating a locomotive engine
    Patent number: 6170452
    Abstract: A method and apparatus for restarting a locomotive engine based on the lubricating oil temperature Toil at the time of shutdown and an average oil cool down rate R. The average cool down rate R may be a function of the ambient air temperature TAIR at the time of shut down. The method and apparatus of this invention allows the engine to be shutdown during periods of inactivity to conserve fuel, but prevents the engine from cooling below a predetermined temperature in order to avoid excessive wear in operating limitations upon restart.
