The operation of automotive equipment in conditions of low temperatures is associated with a large number of difficulties and premature failures, which arise, among other things, due to supercooling of diesel fuel. At the same time, despite the obvious problem, there are no effective solutions in mass production in our country, which leads either to an increase in engine start time or to the need to independently manufacture appropriate technical solutions, which is associated with high risks. It is also worth noting that it is necessary to develop heating systems for the entire fuel system, not just the fuel tank, since clogging of filters and fuel lines is the most common cause of failures. The article draws up a schematic diagram and analyzes the factors affecting the combustion process of diesel fuel, describes devices and technical solutions for heating the fuel system of a diesel engine, provides a device and a method for calculating the geometric characteristics of a filler neck for operation in winter conditions. The methodology is described and studies of the operational parameters of the diesel power plant (YAMZ-236NE) installed on the KI-5540 load stand are carried out. According to the results of experimental studies, the effectiveness of the proposed technological solutions has been proven.
Keywords: automotive equipment, diesel power plant, diesel fuel, diesel fuel heating system.
