Abstract
The invention contemplates a continuously circulating pumped flow of diesel-engine fuel, involving thermodynamic coupling to the engine's coolant-circulation system (a) while the engine is operating and (b) involving selectively available thermodynamic coupling to an externally supplied electric-heater element during periods of engine shut-down. To assure fuel circulation during such operation of the heater element, a rectifier taps the external electric supply to provide pump excitation and thus not to drain the charge on the storage battery associated with the engine.
