Abstract

Due to its properties, natural gas can be used in all transport segments. Compressed natural gas is effective in transport, which is operated in urban locations. This is passenger, light freight transport, utility machinery. The environmental impact of large fleets is higher than personal vehicles due to large annual mileage, so the fleets of trucks operating in the cities (municipal vehicles, buses) are the most significant for the introduction of new innovative solutions in terms of improving the environmental friendliness of vehicles. The problem of collecting municipal waste and its disposal are among the most important utilities. Vehicles for the export of solid household waste on compressed natural gas will reduce harmful emissions into the environment and create less noise compared to diesel counterparts, which is especially true in the morning. We considered the main manufacturers of garbage trucks in Russia. The trend of recent years is an increase in the proportion of rear-loading garbage trucks, which are gradually crowding out the rest. To form a natural gas automobile market, it is necessary to develop a service infrastructure: system of gas stations and fuel delivery, diagnostic and service centers. We also considered the issues of ensuring the required service quality for gas vehicles. One of the factors affecting the reliability of a vehicle is the quality and reliability of its components, assemblies and systems. We analyzed the defects of gas equipment and offered an adjustment of the maintenance process for gas equipment.

Introduction

Urban pollution is a growing concern for the effects on human health. The key factors that affect air pollution from automobile transport include low environmental performance of vehicles produced in the country, low quality of motor fuel, and increase in international and intercity traffic [1]. Natural gas is considered an alternative type of fuel that can best replace conventional fuels in order to reduce their environmental impact. The control of pollutant emissions from vehicles that travel along fixed routes on a daily basis, such as buses and garbage collection vehicles, is very important. The fleet of utility machinery used to restore order in the cities and on the roads is extremely diverse. The utility machinery is designed for year-round maintenance and cleaning of roads, city streets, courtyards from garbage, removal of municipal solid waste to special landfills. The production of this type of equipment and machinery occupies a worthy place in the automotive industry. More than 150 models of garbage trucks are produced in Russia, which differ in the basic chassis, loading and unloading method, mass of transported garbage, garbage compaction coefficient in the body, as well as in the design of the main equipment components and the external design. The share of garbage trucks in the total volume of utility machinery is on average about 35% in Russia. About 2-2.5 thousand new cars are replenished during the year. Garbage trucks are one of the most popular types of utility machinery. They have long become an integral part of the life of large and small cities. The use of compressed natural gas as a motor fuel can significantly reduce the environmental impact of exhaust gases, as well as achieve significant operational savings due to the low cost compared to petroleum types of motor fuel, which is especially important for garbage trucks traveling many kilometers a day. The issues of increasing the production of automotive vehicles operating on natural gas (methane), as well as expanding the gas filling infrastructure in Russia, are discussed at the government level. These steps, as well as rising oil prices, shall significantly increase the demand for gas engine fuel.

Conclusion

In search of environmental benefits, developed countries have been trying to increase the use of alternative fuels in transport for many years. The process of mass introduction of alternative fuels is inevitable, as it is determined by objective reasons for the limited oil reserves in the world and increasing environmental requirements. The greatest prospects, especially in our country, are those alternative types of fuel, the initial basis of which is natural gas. Natural gas garbage trucks are environmentally friendly, economical, and generate less noise. To develop the compressed natural gas automobile market, it is necessary to ensure the development of the infrastructure for refueling and service support of this type of equipment. However, the issue of the uptime of utility vehicles remains important. Improving the quality of warranty service is provided by the improvement of technological processes and by preventing sudden failures.
