Abstract

AbstractThis study focuses on developing an innovative device for isolating and managing exhaust gases from diesel locomotive engines, specifically aiming to reduce environmental impact and enhance operational safety. The study used experimental analysis, validated results using Cochrane and Fisher criteria, and conducted empirical data analysis. Study utilized an experimental stand with a 1.9-liter Volkswagen diesel engine, ZIL-130 compressor, custom exhaust gas storage system with tanks, thermometers, pressure gauges, and control valves. The study developed a mathematical model analysing input parameters and system outputs, achieving 95% accuracy, proving its reliability in representing exhaust gas dynamics of TEM2 diesel locomotives.

Abstract

This research investigates the imperative issue of fuel consumption and emissions in diesel locomotives during idle states, with a particular focus on the deployment of Auxiliary Power Units (APUs) in the neutral position (R-H). Diesel locomotives often exhibit a substantial fuel consumption rate, ranging from 23 to 25 litres per hour, during idling. This paper aims to elucidate the intricacies of optimising fuel consumption while concurrently addressing emission concerns without disrupting essential locomotive functions. In the quest for improved fuel efficiency and reduced emissions in locomotive operations, the utilisation of APUs in the neutral position (R-H) emerges as a pivotal point of investigation. APUs, which are auxiliary engines connected to the primary locomotive engine, play a significant role in achieving these objectives. The study delves into the health status and functionality of APUs during the locomotive's neutral state, examining their impact on fuel consumption and emissions. A comprehensive understanding of this aspect is crucial for developing effective strategies to enhance locomotive performance while curbing environmental impact. It is crucial to recognise that locomotives serve essential functions even when idling, such as supplying compressed air to maintain brake pipe integrity, powering the locomotive control system, and ensuring the charging of batteries. Consequently, locomotive operators often refrain from shutting down the primary diesel engine to conserve fuel. This research, through a meticulous analysis of APUs in the neutral position, endeavours to strike a balance between fuel conservation and the preservation of critical locomotive functions. By exploring the intricacies of APU utilisation, this study contributes to the ongoing efforts aimed at achieving sustainability and improved fuel economy within the railway industry.

Abstract

Introduction. Replacing the material of monometallic motor-axial bearings currently manufactured from bronze to aluminium alloy is advisable to improve traffic safety due to the higher reliability and efficiency of such bearings.Materials and methods. This article studies the materials of monometallic motor-axial bearings, bronze and the proposed complex aluminium-tin alloys. Mechanical properties are determined by standard methods: tensile strength, relative elongation (ductility), Brinell hardness, impact strength. Antifriction properties (abradability, score resistance, wear resistance of the antifriction alloy and the steel associated with it, the heating temperature of the steel surface and the coefficient of friction) were determined according to the methods of the Railway Research Institute approved by JSC Russian Railways on the SMTs-2 friction machine. Bronze and three grades of aluminium alloys were tested with M-14V2 diesel oil, and bronze, B16 babbitt and one grade of aluminium alloy were tested with axial oil.Results. This research shows the possibility of replacing bronze with complex-alloyed aluminium alloys both in terms of economic indicators and antifriction properties. A comparison of mechanical properties is carried out, in most of which aluminium alloys are found superior or not inferior to bronze. The exception is ductility, in terms of which bronze surpasses the proposed alloys.Discussion and conclusion. According to the complex of service characteristics obtained in laboratory studies, it seems expedient to replace bronze with complex aluminium antifriction alloy. The final decision on such a replacement could be made after bench and operational tests of motor-axial bearings on diesel locomotives.

Subjects
locomotive diesel engine, air supply system, supercharging units, turbocharger, registered supercharging system, graph-analytical computation, Railroad engineering and operation, TF1-1620
Abstract

Introduction. The diesel air supply system is designed to increase the air supply to the piston part of the engine, which increases its power. The system includes a supercharging unit (turbocharger) and an aftercooler. As their connection with the piston part is gas-air, this limits the range of feasible operation of the diesel engine. In recent years, the development of the air supply system, which is contributed to the improvement of the fuel efficiency of the diesel engine, is aimed at increasing the turbocharger efficiency and expanding its feasible operation range. The article proposes a new way of improving the fuel efficiency of diesel locomotives: control of two supercharging units (registered supercharging) by successively switching on each for diesel operation in each of the two power modes — below and above average power.Materials and methods. A diagram of the diesel engine air supply with a registered supercharging system is given, and a method for graph-analytical computation of the combined operation of supercharging units with the piston part of the engine is given.Results. The authors substantiated and selected ways of increasing the fuel efficiency of diesel locomotives in operation by improving the characteristics of the air supply system at modes below average power. The calculation and experimental method gave an estimate of the increase in the fuel efficiency of a 2TE25K diesel locomotive equipped with a diesel engine with a registered supercharging system, compared with a standard 21-26DG diesel generator.Discussion and conclusion. The practice of creating, researching and implementing registered supercharging systems at JSC Kolomensky Zavod and abroad shows that, despite the complexity of the design, such systems give a significant increase in the efficiency of the propulsion system in operation. It is recommended to check the characteristics of a diesel locomotive with the proposed registered air supply system on a bench diesel generator, followed by an operational check on a diesel locomotive.
