“…According to the regulations of the Russian Federation with an indirect method of static measurements and an indirect method of measurements based on hydrostatic principle, the error of sensors to measure diesel fuel should be no more than 0.65 %. According to literature analysis, sensors with similar accuracy can be attributed to sensors described in the works of the [14,15], such as KRAL Volumeter sensors. According to the information provided in the [14] sensors, with a sensor error of 0.5%, the error of the entire automated accounting system can reach more than 10%.…”

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.

“…In this type of test, the real operating conditions of the vehicles are simulated in standardized tests. It has been shown, however [7,8,14,15,17], that the test cycles used in type approval do not reflect the real conditions of the engine's actual operation. This is mainly due to the wide variety and diversity among machines and vehicles classified under the NRMM (Non-Road Mobile Machinery) group.…”

The article concerns the research on the emission of pollutants of a rail-road tractor in two stationary research tests. The purpose of the tests was to carry out control tests of pollutant emissions and their analysis. The object used during the works was approved in accordance with the Stage V standard, which requires measurements of emissivity both in stationary, dynamic and real conditions. Despite the requirement to test engines installed on a vehicle during their normal duty cycle with PEMS, the emission limits measured in this test have not yet been defined. Therefore, the work below focuses on the stationary test cycle. The measurements were carried out in accordance with the combustion engine operating points described in the approval test, and then compared with the modernized NRSC test. It contains modified measuring points and rotational speeds of the crankshaft, adopted on the basis of the most common operating parameters of agricultural tractor combustion engines in real operating conditions. The measurements were performed with the use of a mobile dynamometer and devices for measuring emissions of harmful exhaust gas compounds and recording on-board data. In the test, the vehicle drive system worked at fixed operating points, with defined values of crankshaft rotational speed and load. Based on the recorded data on the concentrations of pollutants in the exhaust gases, the specific emission of the object was determined. In the final stage of the work, these data were used to perform a comparative analysis with the emission limits contained in the standard.

“…In terms of mass passenger transport a direct comparison between rail passenger vehicles (motor coach or tram) and buses should be considered. Especially since the most modern urban bus solutions to improve their fuel economy and ecological indicators [3] have been the direct result of increasing the reliance of RDE testing for road vehicles belonging to the public transport sector [4,5]. A direct comparison would serve as a guideline for municipalities in choosing between the investments in different public transport technologies.…”

The article discusses the results of applying real driving emissions (RDE) testing methods in measuring the exhaust emissions of a passenger rail vehicle. Portable Emissions Measuring Systems (PEMS) were used to measure the exhaust emissions from a motor coach in real operation, performed on a test track for selected drive cycle parameters. The road emission values of exhaust components have been calculated and compared to road vehicles and road exhaust emission limits based on the legal norms. The assessment was concluded with a comparison of the environmental cost, in terms of exhaust emissions, of transporting passengers using the tested rail vehicle relative to alternative road transport, based on measurements in real operating conditions.
