Today, most motor fuels are made from non-renewable sources of petroleum origin. In connection with the environmental problems associated with the use of traditional motor fuels in motor vehicle engines, many countries are implementing strict requirements for the greening of motor vehicles.At the same time, vehicles with diesel engines are quite attractive in terms of consumption of alternative motor fuels. One of the ways to increase the environmental safety of vehicles with diesel engines is the complete or partial replacement of diesel fuel with alternative fuels. In this regard, research and development in the field of energy resource use in road transport has been significantly intensified, and new programs are being developed to expand the use of alternative fuels. The main focus of the researchers on improving environmental safety is the complete or partial replacement of diesel fuel with alternative fuels, which can be of petroleum or non-petroleum origin. Such fuels can be: liquefied petroleum gas, compressed natural gas and associated gases, diesel biofuel, alcohols and ethers, as well as hydrogen, etc.The article examines the problem of alternative types of fuel and the use of new energy sources in the search for more ecologically clean, cheap and less scarce fuel. To solve this problem, it is necessary to perform an analysis and determine the possibilities of increasing the environmental safety of motor vehicles with diesel engines when using different alternative fuels.The analysis carried out in the work showed that the considered fuels are promising with the proper organization of the work process of motor vehicle diesel engines. However, in a number of cases, for example, when using hydrogen, alcohols, it is necessary to significantly change the design of the engine, which requires significant costs. The use of alternative, more environmentally friendly motor fuels, such as compressed natural gas, diesel biofuel of vegetable or animal origin, etc., will allow to significantly expand the fuel base of motor vehicle diesels and does not require a significant change in their design.In further research, an important task is to develop a methodology for evaluating the use of alternative fuels, which will combine a complex of functional and mathematical models to determine the energy efficiency and environmental safety of vehicles with diesel engines when using alternative fuels both in their pure form and in the form of mixed fuels.

The paper considers problems of import substitution of parts for wheels and motors units for freight and shunting diesel locomotives with 1050 and 1250 mm wheels and it also considers a task of modernization of technically outdated assemblies. In result of the analysis the authors revealed that it is necessary to: 1) develop a new assembly of motor support bearings with the use of domestic parts; 2) create a new design of an electric traction motor suspension for the substitution of a spring suspension that has wearable parts; 3) organize a search for solutions for perspective diesel locomotives that are intended to operate on the Eastern polygon. For diesel locomotives with 1050 mm wheels the authors propose designs of a frame support traction drive equipped with flat rubber-metal elements and a traction drive with rigid support of an electric traction motor on wheel centres by the use of domestic bearings. Instead of the spring suspension the authors recommend to use suspensions with flat rubber elements and spherical rubber-metal mounting, which will provide interoperability of bogies with modified and unmodified electric traction motors. For perspective diesel locomotives with 1250 mm wheels the authors propose designs of two-axle bogies equipped with high-torque commutator motors and a traction drive with a frame support suspension of a traction motor and an axial gearbox.

Abstract The American Petroleum Institute method for determination of diesel-range total petroleum hydrocarbon (TPH) by gas-liquid chromatography with flame ionization detection was modified to allow simultaneous determination of motor oil. Motor oil elutes as a broad hump of unresolved alkanes and can be distinguished readily from diesel fuel and other fuel oils by its profile. The boiling point ranges for No. 2 diesel fuel and motor oil are C10– C21 and C21–C38, respectively, and these ranges define TPHs in diesel fuel (TPH-D) and motor oil (TPH- M). By this convention, less than 6% of No. 2 diesel is characterized as TPH-M, and less than 9% of motor oil is quantitated as TPH-D. Inlet discrimination was observed when motor oil was injected with a splitless injector. Accurate motor oil quantitation with splitless sample introduction requires calibration with the product or triacontane, which has a similar response factor. Detector response to motor oil (and other petroleum products) and a homologous series of n-alkanes was nearly constant when on-column injection was used. Instrument detection limit for motor oil was about 0.5 μg (split- less injection, total area under the curve), and the widest linear range (up to 100 μg) was obtained by subtracting the solvent chromatogram. Procedures for isolation of motor oil from oil-in-water (O/W) and water-in-oil (W/0) emulsions are described. Method detection limits for diesel fuel and motor oil in purified water were 0.041 and 1.5 mg/L, respectively.

Abstract Under the low load conditions, the motor drives the compressor to increase the intake of the engine, and under the high load conditions, the motor recovers the excess exhaust energy, which greatly improves the performance of the diesel engine in all aspects. In this paper, the one-dimensional simulation prediction model of TBD620V16 diesel engine is established and checked. On this basis, the external electric auxiliary turbocharging system of motor is established. The influence of motor power on the performance of diesel engine under different working conditions is studied by simulation, and the control strategy is put forward according to the influence of power and economy of diesel engine under low load. Based on this control strategy, the improvement effect of power performance and economy under low load conditions is studied. The results show that there is an optimal motor power in each load condition to make the comprehensive thermal efficiency of diesel engine reach the maximum value. Under low load condition, with the increase of diesel engine speed, the pressure ratio of electrically assisted turbocharged diesel engine is higher and the fuel consumption is lower. When the diesel engine is accelerated from 25% to 30% load condition, the supercharged pressure of electrically assisted turbocharged diesel engine is stabilized for about 3s, and the supercharged pressure is higher when it is stable, and BSFC is significantly lower than that of traditional turbocharged diesel engine.

The article considers methods for studying torsional vibrations of the wheel-motor block of a diesel locomotive UZTE16M. The diesel locomotives in question were modernized at the structural enterprise “O’ztemiryo’lmashta’mir” (Machine building and repair in Uzbekistan Railways company) under the joint-stock company “O’zbekiston temir yo’llari” (Uzbekistan railways). The authors of the article developed a dynamic model for the analysis of torsional vibrational movements that occur in the traction transmissions of the UZTE16M diesel locomotive, taking into account the geometric dimensions of the electric traction motors of the main locomotives and the degree of their wear. Based on the model of the wheel-motor block of mainline locomotives, differential equations of the torsional-vibrational motion of traction gears are obtained in the form of Lagrange equations of the 2nd kind. The results of numerical studies of the amplitudes of torsional vibrations of the wheel-motor block of the UzTE16M locomotive at different frequencies are presented. All calculations were performed in the MATHCAD 15 environment.

Testo completoAbstract (sommario):
One of the assumptions made during the modernization process of diesel shunting locomotives is the replacement of a diesel traction motor with a DC generator with an electric asynchronous traction motor. The article aimed to develop a method of selecting energy-efficient parameters of an asynchronous electric traction motor for diesel shunting locomotives, which will ensure that its operating energy efficiency will be as high as possible. The method was verified on the example of a locomotive series ChME3 (ЧMЭ3, ČME3, ČKD S200). It has been found that using a traction asynchronous electric drive on a ChME3 locomotive, its efficiency increases in comparison with DC electric motors by 3–5% under the long-term operation modes and by 7–10% during locomotive operation with traction at the adhesion limit. Using a new traction gearbox with a higher gear ratio expands the speed range in which the asynchronous traction drive operates with a high-efficiency factor. It is effective to use a traction asynchronous electric drive to modernize ChME3 diesel locomotives in case of their use under the modes requiring the implementation of maximum traction forces at low speeds. A further increase in the efficiency of the traction asynchronous electric drive is possible based on the optimal design of the wheel-motor unit and the asynchronous traction electric drive.

The issue of updating the locomotive fleet of industrial enterprises by modernizing outdated diesel locomotives with hydraulic power transmission was considered. The analysis of existing modernizations shows the possibility of using traction electric drive while preserving the original group drive of wheel pairs. This approach is used by manufacturers when updating outdated and creating new diesel locomotives and traction modules for rolling stock. A possible option is the use of single-motor carts. Previous studies on the choice of the type of wheel pairs drive were analyzed and it was established that the use of a group drive of wheel pairs provides the possibility of realizing high traction forces without additional devices, and the drive itself has a lower cost. This determines the expediency of using a group drive of wheel pairs when modernizing diesel locomotives with hydraulic power transmission. To realize these advantages, it is necessary to use a traction electric drive based on electromechanical alternating current converters. This approach was implemented by Mykolaiv Locomotive Repair Plant LLC during the modernization of TGM6 diesel locomotives. The diesel locomotive is intended for shunting and hauling operations, as a result of which it was assumed during the design that the traction force when moving is equal to 320 kN, the continuous traction force is 300 kN, and the maximum speed is 50 km/h. The power plant consists of a modern Cummins diesel engine and a synchronous generator. A frequency-controlled asynchronous traction electric motor is used to drive the wheel pairs. Power and control of the electric motor is carried out using a voltage inverter. Diesel locomotives use a controlled electric drive of cooling motor-fans, and semiconductor converters are used to power auxiliary systems. The locomotive and its systems are controlled by a microprocessor control system. The application of the traction electric drive based on the asynchronous electric motor provided the estimated efficiency of the diesel locomotive and the efficiency of the diesel power at the nominal power and the estimated speed of the long-term mode, equal to 6 km/h, are 0.312 relative units and 0.69 relative units, respectively. The analysis of ways to improve the traction electric drive to reduce the consumption of fuel and energy resources was carried out. It was determined that the use of a power plant with energy storage and the use of two traction electric motors for the group drive of wheel pairs may be expedient

O estudo de fontes alternativas de energia ao óleo diesel mineral, como o biodiesel, com origem renovável, é importante para o meio-ambiente e diversificação da matriz energética. Neste estudo foram levantados o consumo específico de combustível, o valor calórico do combustível e a eficiência do conjunto motor gerador da marca BRANCO em função de cargas resistivas, sob as seguintes proporções volumétricas entre o óleo diesel mineral com biodiesel: 0% (B0), 20% (B20), 40% (B40), 60% (B60) e 100% de biodiesel (B100). Para o ensaio utilizou-se motor de 7,36 kW, com gerador elétrico acoplado de 5,5 kW. As cargas utilizadas, 0,5 kW; 1,0 kW; 1,5 kW e 2,0 kW foram elevadas até 5,0 kW, oriundas de um dinamômetro de cargas resistentes. Assim, o desempenho do conjunto para cargas abaixo de 1,5 kW mostrou-se menor, pelo maior consumo específico de combustível (CEC), e redução na eficiência do conjunto motor gerador para a faixa de potência. Para as proporções de biodiesel B40, B60 e B100 os resultados descreveram redução no valor calórico e aumento do CEC. Portanto, realizando comparação das proporções de biodiesel com o óleo diesel, a proporção B20 substitui parcialmente o óleo diesel, sem perdas significativas do desempenho do motor gerador.

DISTÂNCIA DA REDE ELÉTRICA QUE VIABILIZA O USO DE MOTORES DIESEL EM ÁREAS IRRIGADAS DO BRASIL Rodrigo Otávio Câmara Monteiro; Priscylla Ferraz; Rubens Duarte Coelho; Ronaldo Antônio do SantosEscola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, Piracicaba, SP rocamara@esalq.usp.br 1 RESUMO Na maioria das regiões do país, a energia elétrica aparece como a alternativa, economicamente mais viável, no acionamento de bombas em áreas irrigadas, o que justifica seu uso por aproximadamente 70% dos irrigantes. No entanto, em determinadas situações, não se dispõe, nas proximidades, de rede elétrica, o que passa a viabilizar o uso de motores diesel. Este trabalho, portanto, propôs a análise dos custos horários de bombeamento com a operação de motores diesel e elétricos nas 5 regiões do Brasil. Considerou-se as composições tarifárias verde, azul e convencional, período de irrigação de 2, 4, 6 e 8 meses por ano e operação no horário de ponta e fora de ponta. Para essa avaliação, foi considerado um motor diesel e elétrico, de potência comercial de 50 cv. O ponto de equilíbrio entre motor elétrico e diesel foi determinado pela distância da rede de energia elétrica até o local de consumo. A viabilidade de utilização dos motores diesel em relação ao acionamento de motores elétricos foi encontrada a partir de distâncias da rede de transmissão elétrica de1,32 a8,71 km, sendo a primeira a condição mais atrativa, encontrada na região Sudeste, com 2 meses/ano de irrigação, na tarifa convencional.

VIABILITY OF DIESEL MOTOR USE IN IRRIGATED AREAS OF BRAZIL DUE TO DISTANCE FROM ELECTRIC POWER LINES 2 ABSTRACT In most agricultural areas ofBrazil, electric power seems to be the most feasible economic alternate methods for the functioning of pumps in irrigated areas, therefore 70% of irrigation systems use it. However, the viability of electric power lines is restricted to only one part of rural areas, making it necessary the implementation of diesel engines as a source of electrical power for water management. The aim of this study was to investigate the viability of the use of electric energy and diesel motors. For this study, an electric motor and a diesel one, both of 50HP potency, were evaluated, taking into consideration the following variables: tax composition, areas of the country and number of operation hours per year. The viability of the diesel engine use in relation to implantation of electric motors was determined from distances that ranged from1.32 kmup to8.71 kmbetween the consumption place and the electric power lines. The most favorable condition is the one found in the southeast of the country: 2 irrigation months/year.KEYWORDS: Electric energy, irrigation, pump costs

Os atuais elevados preços do barril de petróleo no mercado internacional, a possibilidade de geração de postos de trabalho e renda com a conseqüente fixação do homem no campo, as excelentes e variadas condições climáticas e os tipos de relevo fazem com que o Brasil, com suas extensas áreas agricultáveis, destaque-se no cenário mundial em relação à sua grande potencialidade de geração de combustíveis alternativos. A situação ambiental faz com que o ser humano trabalhe no desenvolvimento de alternativas energéticas, destacando-se aquelas oriundas de fontes renováveis e biodegradáveis de caráter eminentemente sustentável. Assim, objetivou-se com este trabalho avaliar o desempenho de um motor ciclo diesel, funcionando em momentos distintos com diesel mineral e misturas deste com biodiesel nas proporções equivalentes a B2 (98% de diesel mineral e 2% de biodiesel), B5 (95% de diesel mineral e 5% de biodiesel), B20 (80% de diesel mineral e 20% de biodiesel) e B100 (100% de biodiesel). Para a realização dos ensaios, foi utilizado um motor ciclo diesel de um trator VALMET 85 id, de 58,2kW (78 cv), de acordo com metodologia estabelecida pela norma NBR 5484 da ABNT (1985) que se refere ao ensaio dinamométrico de motores de ciclo Otto e Diesel. Concluiu-se que a potência do motor ao se utilizar biodiesel foi inferior àquela quando se utilizou diesel mineral. Observou-se que, em algumas rotações, as misturas B5 e B20 apresentaram potência igual ou até superior, em algumas situações, àquela quando se utilizou diesel mineral. A melhor eficiência térmica do motor foi verificada na rotação de 540 rpm da TDP equivalente a 1720 rpm do motor.

The development experience of foreign and domestic specialists of converting diesel engines into monogas with spark ignition was studied. Disadvantages and advantages of use as motor gas fuel for diesel engines are analyzed. Ways of converting diesel units of the oil and gas industry to liquefied and compressed gas fuels according to various schemes are formulated.. Modelling of the energy efficiency of diesel units of the oil and gas industry during the conversion of diesel drives to the use of alternative fuels was performed. It has been found that when converting diesel engines of power drives of the oil and gas industry to gas motor fuel, it is possible to ensure torque, fuel consumption, and power indicators that are practically identical to the similar indicators of diesel engines before their conversion to gas. It has been established that when converting diesel units of the oil and gas industry to gas motor fuel, when converting diesel engines to a propane-butane mixture, in comparison with natural gas, it will be possible to provide better fuel, power, and environmental characteristics. It is proved that the simulation results are in good agreement with the practical results already obtained on automobile and technological transport. Key words: alternative fuel, diesel engine, drilling rig, gas refurbishment, energy efficiency.

As the energy crisis and environmental pollution continue to be a gradual threat, the energy saving of transmission systems has become the focus of railway vehicle research and design. Due to their high-power density and efficiency features, permanent magnet synchronous motors (PMSM) have been gradually applied in railway vehicles. To improve the efficiency of the transmission system of diesel railway vehicles, it is a good option to use PMSM as both a generator and traction motor to construct a full permanent magnet transmission system (FPMTS). Due to the application of the new FPMTS, some of the original control strategies for diesel railway vehicle transmission systems are no longer applicable. Therefore, it is necessary to adjust and improve the control strategies to meet the needs of FPMTS. We studied several key issues that affect the reliability and comfort of the vehicles. As such, this paper introduced the FPMTS control strategy, including the coordinated control strategy of the diesel and the traction motor, the two degrees of freedom (2DOF) decoupling current regulator, the maximum torque control of the standardized unit current, the wheel slip protection control, and the fault protection strategy. The experiment was carried out on the test platform and the test run of the diesel shunting locomotive equipped with the FPMTS. The results showed that the control strategy described in this paper met the operation characteristics of the FPMTS and that the control performance was superior. The study of FPMTS lays the foundation for the subsequent application of permanent magnet motors in high-powered diesel locomotives and high-speed diesel multi-units.

In actual diesel engine work cycle is part of the heat input that occurs at constant volume and partly at constant pressure. Therefore, in the calculation of the design of the modern diesel motor cycle, a limited pressure air cycle (combined cycle) is used. The purpose of this study is to analyze the performance of the diesel engine in the PLTD Tenau-Kupang and to find out the deviations or losses that occur in the diesel motor work cycle. From the results of the research in the form of an analysis of calculations at 600 rpm engine speed, it can be concluded that the basic factors of the performance of an engine include the average effective pressure (MEP), piston speed, ratio of stroke length and cylinder diameter, number of cylinders, and calculations for power. The resulting motor is close to the actual motor power.

At the end of the 20s of the last century, automotive diesels made their debut on the markets of European countries. In the USSR, the Scientific Automobile Engine Institute in 1929 began to test tractors running on oil, and research their engines. (Research purpose) The research purpose is in searching for the key points that influenced the creation of the first automobile-type diesels by the Scientific Automotive Institute, the choice of the type and characteristics of these engines; identifying the factors that influenced the implementation of these structures in metal. (Materials and methods) The first directive decisions on automotive dieselmotors appeared in the USSR in 1929; they were set out in the resolution of the Central Committee of the CPSU (b) of July 29, 1929. "On the state of defense of the USSR". NATI-1-60 diesel and its NATI 2-40 version for the automotive industry has been developed by the Research Automobile and Motor Institute. The NATI-1-60 diesel had a power of 60 horsepower at 1600 rpm; NATI-2-40 diesel was designed for wheeled tractors of the “International” type, had a power of 40 horsepower at 1400 rpm. (Results and discussion) The production of prototype engines was complicated by the lack of production facilities at NATI, and the production of prototypes at the Institute's plant was not carried out. The government did not allocate currency for the purchase of imported equipment. (Conclusions) The Automobile and Motor Research Institute, not being able to produce its own diesel engines, tried to do this through broad cooperation between domestic enterprises. However, the construction of the first diesels faced the reluctance of the giant factories to produce them, despite the guidelines. This caused a delay in the dieselefication of the country's automotive engine industry at the initial stage.

Produksi minyak dunia diperkirakan telah mencapai puncaknya pada tahun 2000, ini berarti bahwa eksplorasi minyak bumi sudah maksimal dan selanjutnya akan mengalami penurunan. Ini akan menyebabkan dalam kurun waktu 20 tahun produksi minyak dunia akan kembali seperti pada tahun 1980-an(OPEC ,2009). Di lain pihak ketergantungan terhadap minyak bumi pada waktu yang sama akan terus meningkat akibat pertambahan penduduk dan kegiatan industri dan pembangunan. Akibat dari hal ini adalah harga energi yang semakin tinggi dan pasokan minyak yang menurun. Hal ini dapat dirasakan dari naiknya harga minyak mentah dan dicabutnya subsidi harga bahan bakar minyak oleh pemerintah Indonesia. Pada penelitian ini peneliti tertarik pada minyak solar dari oli bekas(Diesel – Like Fuel) di gunakan sebagai bahan bakar pada motor diesel dengan menggunakan Multi Swirl Combustion System (MSCS) Piston Chamber. Penelitian ini dilakukakan untuk mengetahui unjuk kerja dari motor diesel Multi Swirl Combustion System (MSCS) Piston Chamber saat menggunakan bahan bakar solar dari daur ulang minyak pelumas bekas(Diesel – Like Fuel) dan minyak solar(Pertamina Dex) sebagai pembanding.

Testo completoAbstract (sommario):
Due to the increase in the cost of diesel fuel, much attention is paid to the use of alternative types of fuel on diesel locomotives. Variants of using fuel obtained from coal, plants, gas fields and hydrogen are considered. Natural gas is the cheapest and most accessible today. The use of specially designed gas-piston engines on diesel locomotives, operating when the gas-air mixture is ignited from an external source, is the most attractive option. However, this approach has certain disadvantages:• it is necessary to create a new engine, since the modernization of existing engines requires serious structural changes;• gas piston engine operates essentially according to the Otto cycle and has lower efficiency and power indicators as compared to a diesel engine;• when modernizing existing diesel locomotives, switching to the Otto cycle excludes the possibility of using diesel fuel.Conversion of diesel locomotives to gas fuel must be carried out using the gas-diesel cycle. This approach is most acceptable for the modernization of diesel locomotives of the existing fleet, since it preserves the thermal performance of the engine and makes it possible to transfer diesel locomotives back to operation on diesel fuel. The main obstacle to the transfer of diesel locomotives to the gas-diesel cycle is the low degree of replacement of diesel fuel with gas. This circumstance is determined by the significant difficulties in ensuring the operation of the engine in the gas-diesel cycle at low loads and idling. It is necessary to ensure a stable supply of ignition fuel in these modes and guaranteed ignition of the gas-air mixture from it. The solution to this problem is ensured by maintaining a given stoichiometric ratio in the gas-air mixture and a temperature sufficient to ignite the ignition portion of the fuel.The main way to regulate the stoichiometric ratio is to reduce the amount of air entering the cylinders by throttling it at the engine inlet. This article discusses the methodology for calculating the performance of the engine when throttling the air inlet.

A combustion engine-driven vehicle can be made more fuel efficient over some drive cycles by, for example, introducing electric machines and solutions for electrical energy storage within the vehicle’s driveline architecture. The possible benefits of different hybridization concepts depend on the architecture, i.e., the type of energy storage, and the placement and sizing of the different driveline components. This paper examines a diesel electric plug-in hybrid truck, where the powertrain includes a diesel engine supported with two electric motors, one supporting the crank shaft and one the turbocharger. Numerical optimal control was used to find energy-optimal control strategies during two different accelerations; the trade-off between using electrical energy and diesel fuel was evaluated using a simulation platform. Fixed-gear acceleration was performed to evaluate the contribution from the two electric motors in co-operation, and individual operation. A second acceleration test case from 8 to 80 km/h was performed to evaluate the resulting optimal control behavior when taking gear changes into account. A cost factor was used to relate the cost of diesel fuel to electrical energy. The selection of the cost factor relates to the allowed usage of electrical energy: a high cost factor results in a high amplification from electrical energy input to total system energy savings, whereas a low cost factor results in an increased usage of electrical energy for propulsion. The difference between fixed-gear and full acceleration is mainly the utilization of the electric crank shaft motor. For the mid-range of the cost factors examined, the crank shaft electric motor is used at the end of the fixed-gear acceleration, but the control sequence is not repeated for each gear during the full acceleration. The electric motor supporting the turbocharger is used for higher cost factors than the crank shaft motor, and the amplification from electrical energy input to total energy savings is also the highest.

O biodiesel de sebo bovino é considerado uma alternativa de baixo custo e de grande disponibilidade por ser resíduo da produção agropecuária brasileira, que é uma das maiores do mundo. Raros são os trabalhos que mostram a utilização do biodiesel de sebo bovino em motores diesel. Assim, o objetivo deste trabalho foi verificar o efeito da mistura de biodiesel bovino na proporção de 5% ao óleo diesel comercial no desempenho do motor, possíveis consequências internas no motor e nas características do óleo lubrificante após o uso prolongado em motor diesel. Foram realizados ensaios em bancada dinamométrica utilizando um trator agrícola. O desempenho do motor foi determinado através da tomada de potência (TDP). O motor foi operado por 600h durante as quais foi determinada a potência, o consumo de combustível e analisadas as amostras de óleo lubrificante a cada 100h. Ao final do ensaio, o motor foi aberto e inspecionado. A análise do óleo lubrificante mostrou nível de contaminação crítico a partir das 400h, mas a inspeção visual do motor não detectou nenhum desgaste interno. O motor funcionou normalmente, embora tenha ocorrido tendência de redução na potência e aumento de consumo de combustível ao longo das 600h.

The relevance of the article is due to the need to replace petroleum fuels with motor fuels obtained from alternative raw materials. Hydrogen is considered as a promising alternative fuel. The use of hydrogen as a motor fuel makes it possible to solve the problem of a cardinal reduction in carbon dioxide emissions into the atmosphere. Using the DIESEL-RK software package, computational studies of the effect of hydrogen supply on the working process of the gas-diesel engine D-245 were carried out. The diesel cycle of the engine and its gas-diesel cycle were calculated with hydrogen supplies equal to 5, 10, 20, 40, 60 and 80% (taking into account the difference in the heat of combustion of the studied fuels). The maximum effective efficiency of a diesel engine is achieved when 40% hydrogen is supplied to the combustion chamber. In this case, compared to operation only on petroleum diesel fuel, the effective efficiency of the diesel engine increased by 7%.
