ABSTRACT:
An apparatus particularly adapted to installation in large railroad diesels or other large diesel applications which provides heated coolant for circulation in the large engine during shutdown or layover periods, also providing heat for accessories and electrical charge for batteries. Main engine fuel supply is used to run a small diesel engine which drives an inverter and a centrifugal pump, the discharge of which is severely stifled or throttled, the inefficiency of the pumping action converting much of the energy of the pump into heat absorbed in the coolant which is then pumped through the regular cooling lines in reverse flow, and to accessories as desired.
