Abstract

In recent years, Ukraine and the world have seen a steady increase in the use of compressed natural gas (LNG) in cars. The main reason for such attention to gaseous motor fuel is its low cost compared to gasoline and diesel fuel. This is also facilitated by the extensive network of autogas filling compressor stations (CNG stations) ofUkrtransgaz, which today is about 150 stations and is constantly growing. Today, the network of CNG stations in the country is used by 35,000 cars, which allows Ukraine to rank seventh in the world in terms of the number of cars running on LNG. The use of methane-based natural gas as an alternative fuel in Ukraine has long begun. Road transport is actively switching to this gas. Currently, the country is conducting a powerful advertising campaign to convert cars from conventional fuel to natural gas. The economic benefits of such a transition are obvious. Natural gas turned out to be almost twice cheaper than propane, which is much cheaper than gasoline. Unlike gasoline and diesel fuel, natural gas does not contain toxic impurities and additives, has a wide range of ignition. Exhaust gases from natural gas engines contain a small amount of normalized harmful emissions. LNG, including biogas, burns more slowly than gasoline, reducing the load on the cylinder-piston group, the engine runs "softer" and quieter. In total, these factors provide double (and more) savings in operating costs, extend the life of the engine by 30-40%, oil and spark plugs - twice, and as a result significantly reduce repair costs. Optimization of the working process of the engine running on gas (increasing the degree of compression of the engine to 10-11; installation of a modern ignition system with modified, optimized for gas fuel characteristics at maximum and variable engine speeds) allows to ensure maximum engine power while maintaining efficiency and environmental parameters. high modern level.
