The prospects of use of alternative types of fuel in road transport

Abstract

The article is devoted to the analysis of possibilities of using alternative types of fuel in transport. Gas engine fuels are considered as potential energy carriers for diesel engines. Since the constructions of vehicles, using gas and traditional types of fuel, have some differences, the most important are the issues of ensuring trouble-free operation: the reliability of design, the development of petrol station chain, and the corporate service system. One of the ways of solving the problem of forecasting the need to expand the network of gas-filling stations for natural gas vehicles (NGV)is presented in the work. It is implemented in the form of program module that allows taking into account the prospects for expansion of the natural gas vehicles park, as well as the risks, which may arise in the process of realization of the long-term strategies for the development of this direction. The issues of ensuring the operational reliability of NGV are considered. The developed methods are aimed at improving the corporate service system of PJSC "KAMAZ". Fundamental defects of gasengines and failures distribution, depending on the operational kilometers, arising in the warranty period of operation, are analyzed in the work.

Natural Gas Utility Machinery Technologies

“…The design feature of KAMAZ gas engines (820.73, 820.74, 820.60, 820.61) is the presence of turbocharger, charge air cooler, electronic control and exhaust gas aftertreatment system. The operational experience of KAMAZ vehicles shows that the main failures in gas engines during the warranty period occur in the first 8,000 km of run [1], therefore it is necessary to investigate the causes of failures. The service life of the garbage truck can be up to 10-15 years.…”

“…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.…”
