Abstract

Innovations and trends in the field of power plants of hybrid cars were covered in the article. The essence of the car's power plant was analyzed. The special transmission of hybrid cars was described. The modes of operation of the power plant in a hybrid car were outlined. Modern technologies of power plants of cars were given. The issue of increasing the efficiency of propulsion system of cars, increasing fuel efficiency and reducing toxic gas emissions in modern automotive industry was considered. It was emphasized that the practical use of combined power plants allows to significantly reduce the cost of transporting goods and passengers by vehicle, as well as to improve energy and environmental characteristics. The main modes of operation of the power plant in a hybrid car were listed by the authors, in particular: electric mode, hybrid mode, charge mode. Trends in the development of electric cars, which use electric propulsion systems instead of internal combustion engines, have been outlined. The trend of recent years in the development of electric cars included: an increase in the range of travel, fast charging and improvement of power electronic systems. The modern development of hybrid cars was analyzed in the article, in particular: Plug-in hybrid cars, use of a 48-volt network, an improvement of control modes in hybrid cars and energy recovery systems. Special attention was paid to changes in driving modes of hybrid cars. In general, the technologies of power plants of cars are developing rapidly, are aimed at reducing fuel consumption. A combination of internal combustion and electric motors in hybrid cars makes it possible to achieve an optimal balance between fuel efficiency and environmental friendliness, and ensures convenience and performance when driving on the road.
