Abstract. The article discusses the problem of improving the technical and economic performance of a car. It is shown that increasing the carrying capacity, specific power, and improving speed indicators will contribute to an increase in vehicle productivity. It has been established that modern turbocharged diesel engines differ from mass-produced ones in having a smaller specific mass and size, greater efficiency and service life, a reduced content of toxic substances in the exhaust gases, and a lower crankshaft speed. In addition, it is shown that one of the ways to reduce the curb weight of trucks (road trains) and buses is the use of lighter structural materials, in particular special aluminum alloys, high-strength low-alloy steels and plastics. As a result of the research, it was found that by adding 15% methanol and 7% isobutyl alcohol to gasoline as a stabilizer, it is possible to increase engine power, reduce the content of nitrogen oxides and hydrocarbons in the exhaust gases and reduce fuel consumption. The anti-knock properties of gasoline can be increased by introducing up to 10% water into the cylinders in the form of a water-gasoline emulsion or separately. However, this does not significantly affect gasoline savings. The use of a mixture of gasoline with 15% methanol and 7% isobutyl alcohol (gasoline savings of up to 14 %) should be implemented gradually, starting with the implementation in the middle zones, since the use of this mixture requires changing the carburetor adjustment and installing additional pipelines to eliminate vapor locks. The next stage of implementation is a separate supply system for methanol and gasoline, which provides savings of up to 20 %. Thus, the main ways to improve the technical and economic performance of a car are: dieselization; increased load capacity and reduced weight; improving engine performance; optimization of specific power using combined power plants; use of new types of fuel.
Keywords: car, diesel, performance, performance, dieselization, load capacity, power.
