ABSTRACT:
The present invention is related to a diesel engine fuel pipeline heating device and particularly to a diesel engine fuel pipeline heating device consisting of an electric heating device and a water (or air) temperature heating device provided to the exterior of diesel engine fuel pipe. A diesel engine equipped with such a heating device can be easily started through the electric heating device to heat the fuel in the fuel pipe up to a suitable starting temperature around 40.degree. C. (or 104.degree. F.) before starting the engine; and after starting the engine for some time, namely, when the temperature in the heating cylinder of water (or air) heating device has risen to the said suitable combustion temperature around 40.degree. C. (or 104.degree. F.), the power source of electric heating device is automatically turned off to stop the heating action. Then the hot water from the water return pipe of radiator or the hot air from the exhaust pipeline of exhaust pipe keeps continued preheating of fuel pipe for a constant temperature through the water (or air) heating device so as to continuously keep the full fuel combustion, easily and smoothyl start and run the engine, save fuel and enhance the horse power of engine.
