Automation of diesel fuel consumption accounting on a special self-propelled rolling stock of Russian Railways

Abstract

The article provides the results of a study to assess the effectiveness of automation of diesel fuel consumption accounting for a certain type of special self-propelled rolling stock of the company Russian Railways. The main current provisions of the fuel consumption assessment are considered. It is proposed to supplement the provisions on the adjustment of fuel consumption standards by identification methods. The identification method includes monitoring actual values, performance indicators, rolling stock mileage and fuel consumption forecasts. The analysis showed that the efficiency of fuel consumption automation can be as high as 30%. The effect is achieved by fulfilling the forecast fuel consumption standards and eliminating unauthorized fuel overruns.

Indirect Fuel Rationing for a Special Self-Propelled Rolling Stock

“…It is clear that the SSRS database does not have operating mode values H wm , H im , and H trm on trip j, which reduces the reliability of the assessment of the normative level of fuel consumption. Finding the solution to the problem is possible by developing methods of statistical analysis and identification, as proposed in [39,40]. One advantage of these methods is the possibility of using a wider range of factors in addition to B N j , H wm , H im , and H trm ; for example, Run factor, temperature, or environmental performance.…”

“…In these works, it is recommended to search for and exclude multicollinear factors when using correlation analysis (see Table 4). The authors propose to use cluster analysis (see Figure 4) [39,40] to solve this problem. The method of selecting factors in an equation of type (3) should take into account a number of elements, as follows:…”

“…Increased efficiency by 30% has been reported [38]. The development of rationing diesel fuel consumption in railway transport, including SSRS [39,40], expands upon the known materials and publications. This paper discusses ways to improve the quality of standardization of diesel fuel consumption when equipping rolling stock with automated fuel consumption accounting systems, as well as when SSRS is equipped only with standard equipment and there is incomplete data on the operating modes.…”

“…The motivation for improving the rationing of SSRS diesel fuel consumption is to solve the problem of improving fuel efficiency, including by reducing deviations between actual fuel consumption and standard values. In an earlier study [39], the authors presented the results of fuel consumption and rationing for SSRS type MLT-6, which is used in the economy of the track in conditions of equipment with its automation system and sensor equipment for fuel consumption of the KVARTA type.…”

Rationing of fuel consumption based on identification of rolling stock modes

“…The factors that can be used in equation ( 1) include the indicators that are studied in (Abas et al, 2017;Association of American Railroads, 2014;Capuano et al, 2017;Gritsenko et al, 2021;Mitrofanov et al, 2017Mitrofanov et al, , 2020Rymaniak et al, 2019;Tshizanga et al, 2017) A significant advantage of the identification methodology for assessing the fuel consumption rate in comparison with those used in the company "Russian Railways" is the ability to configure the operator of the relationship A for a specific type of SSPS, for a specific type of work performed, for work areas. To increase the adequacy of the identified operator A, it is possible to use both linear and nonlinear types of operators.…”
