LOCOMOTIVE ENGINE RESTART SHUTDOWN OVERRIDE SYSTEM AND METHOD

摘要

A system for overriding an EMD locomotive engine protective device (40) whic h includes a low water pressure sensing device (16) in communication with the engine cooling system for shutting down the engine when low water pressure i n the engine is sensed, the override system comprising a water assist pump (20 ) connected to a source of water and communicating with the protective device (40) for supplying pressurized water to the low water pressure sensing devic e (16) to maintain relatively high water pressure to prevent the device (40) from shutting down the engine: and a controller for activating the water assist pump (20) during start up of the engine.
