INVESTIGATION OF THE USE OF PREHEATERS IN DIESEL GENERATOR SETS

The article discusses the use of preheaters on diesel generator sets (DGS) in order to increase their reliability and efficiency at low temperatures. The influence of low temperatures on the operation of diesel engines has been analyzed, the need to use preheaters has been substantiated, and various types of heaters and their effectiveness have been considered. The results of experimental studies by Russian and foreign scientists are presented, confirming a significant improvement in the starting characteristics of the DSU, a reduction in engine wear and an increase in the overall service life of the equipment when using preheaters. The economic efficiency of the implementation of such systems is calculated. Special attention is paid to the problems of DSU operation at low temperatures.
