Electromechanical device for heating diesel fuel locomotive.

The difficulties of starting a diesel motor at negative ambient temperatures are known. It is primarily connected with the peculiarity of ignition of diesel fuel. At negative ambient temperatures the fuel becomes viscous, and its spraying by the nozzles becomes difficult. This problem is solved by installing various additional pre-starting fuel heaters on fuel filters, main pipeline or in the tank. They are autonomous electrical devices. In this paper we consider a new type of preheater. It simultaneously performs both heating and pumping of diesel fuel. This heater is designed on the basis of an electromechanical converter. One of the distinctive features of this device is the possibility of independent regulation of the amount of heating and pressure of the heated fuel. The analysis showed that the heater has the wide-regulating characteristics, provides the ability to obtain and maintain the specified temperature of the heated fuel, pressure and productivity. This device is high-tech and it is characterized by the high structural reliability. [ABSTRACT FROM AUTHOR]
