In various sectors of the economy, including district heating systems in cities and settlements, steam turbine and gas turbine thermal power plants are mainly used. Their operation is based on cogeneration, which is the conversion of chemical fuel energy into electrical and thermal energy. At the same time, a significant part of the heat supply sources are still represented by heating boilers, which consume electricity for their own needs. In the gas industry, diesel engines are used as the drive for gas pumping plants. One of the factors hindering the organization of combined production of electric and thermal energy in heating boilers is the lack of production in Russia of gas-piston power plants with a capacity of more than 500 kW. The use of imported equipment for these purposes is usually not economically and technologically justified. According to the order of the Ministry of Industry and Trade of Russia dated 16.04.2019 No. 1327, the share of imports of gas piston and gas turbine units is planned to be reduced from 70% in 1918 to 25% in 2024. One of the promising directions of creating gas piston installations in Russia is justified: reproduction on a modern technological basis of two-stroke engines produced in the USSR of GD100 series gas piston engines that are still working at a number of facilities. The Russian government is considering converting mainline and shunting locomotives of railway transport to gas-powered fuel. One of the ways of increasing the efficiency of two-stroke engines is shown-in-cylinder mixing of gas with air with pre-chamber-flare spark ignition.
