Abstract
<jats:p>The article describes one of the ways to more efficiently warm up and start diesel internal combustion engines (ICE) of automotive equipment (AT) in winter, as well as a device for its implementation directly on board the equipment. The device implemented by the developed method on board the equipment is a dispenser mixer designed to supply an additional component to the combustion chamber of a diesel engine. The device promptly supplies a small amount of gasoline to a stream of passing air. The results of the conducted tests of a prototype device, which was placed in the power supply system of a diesel internal combustion engine installed on the KI-5540 load stand, are described. In the course of the conducted research, it was found that the combined fuel engine is stable in all operating modes. When gasoline is supplied in the amount of 5-10%, there is an increase in power by 5- 14%, after which the external speed characteristic of the internal combustion engine was determined when the internal combustion engine is running on diesel fuel and combined fuel (with a rational supply of gasoline of 10% of fuel consumption). After that, full-scale tests of the developed method of heating diesel internal combustion engines on AT (two MTZ-82 tractors) at a temperature of minus 25 ° C were carried out. The results of 30 timings showed that the average warm-up time of diesel internal combustion engines operated using a promising method does not exceed 21 minutes to a temperature of 50 ° C, which is almost 1.5 times less than the warm-up time of an internal combustion engine running on conventional diesel fuel. The introduction of the developed method at low temperatures will improve the reliability of starting diesel engines, reduce their warm-up time and reduce the time to prepare the engine for loading by up to 40% by enriching the working mixture with a small amount of gasoline that burns in the combustion chamber at a temperature higher than conventional diesel fuel.</jats:p>
