Opis:
In the current discussions on the future of the automotive industry, two extreme opinions clash: electromobility or vehicles with conventional drive but powered by alternative fuels. The article discusses the issue related to modeling the energy efficiency factors of a combustion engine operating on three types of fuels (Diesel 100%, Biofuel 100%, and Hemp Oil 100%) as well as an electric drive powered by energy from a coal power plant. Analytical research was conducted based on the external characteristics of the engine's performance. The external characteristic of the Fiat Panda 1.3 JTD combustion engine was obtained on the Automex dynamometer. The engine operated on three fuels: Diesel 100%, Biofuel 100% (rapeseed), and Biofuel 100% (hemp oil). The Nissan Leaf vehicle manufacturer provided the external characteristics of the electric engine. The calculation results showed that the combustion engine consumes less energy at lower speeds than the electric one. At higher speeds, the consumption rates are at a similar level. The recipients of the research are both the demand side – that is, vehicle users, as well as future manufacturers and government institutions responsible for shaping and developing future mobility in the field of individual transport.
W toczących się obecnie dyskusjach na temat przyszłości motoryzacji ścierają się dwie skrajne opinie: elektromobilność lub pojazdy z konwencjonalnym napędem, ale zasilane paliwami alternatywnymi. W artykule omówiono zagadnienie związane z modelowaniem współczynników efektywności energetycznej silnika spalinowego zasilanego trzema rodzajami paliw (olej napędowy 100%, biopaliwo 100% i olej konopny 100%) oraz napędu elektrycznego zasilanego energią z elektrowni węglowej. Badania analityczne przeprowadzono w oparciu o zewnętrzną charakterystykę pracy silnika. Charakterystykę zewnętrzną silnika spalinowego Fiat Panda 1.3 JTD uzyskano na hamowni Automex. Silnik pracował na trzech paliwach: olej napędowy 100%, biopaliwo 100% (rzepak) oraz biopaliwo 100% (olej konopny). Zewnętrzna charakterystyka silnika elektrycznego została dostarczona przez producenta pojazdu Nissan Leaf. Wyniki obliczeń wykazały, że przy niższych prędkościach silnik spalinowy zużywa mniej energii niż silnik elektryczny. Przy wyższych prędkościach wskaźniki zużycia są na podobnym poziomie. Odbiorcami badań jest zarówno strona popytowa - czyli użytkownicy pojazdów, jak i przyszli producenci oraz instytucje rządowe odpowiedzialne za kształtowanie i rozwój przyszłej mobilności w zakresie transportu indywidualnego.

Opis:
The study is devoted to the possibility of increasing the efficiency of the working process in dual-fuel combustion chambers of gas turbine engines for FPSO vessels. For the first time, it is proposed to use the advantages of plasma‒chemical intensification of the combustion of hydrocarbon fuels in the dual-fuel combustion chambers, which can simultaneously operate on gaseous and liquid fuels. A design scheme of a combustion chamber with a plasma‒chemical element is proposed. A continuous type mathematical model of a combustion chamber with a plasma‒chemical element has been developed, which is based on the solution of a system of differential equations describing the processes of chemical reactions in a turbulent system, taking into consideration the initiating effect of the products of plasma‒chemical reactions on the processes of flame propagation. A modified six-stage kinetic scheme of hydrocarbon oxidation was used to simultaneously predict the combustion characteristics of the gaseous and liquid fuels, taking into account the decrease in the activation energy of carbon monoxide oxidation reactions when the products of the plasma‒chemical element are added. The results reveal that the addition of plasma‒chemical products significantly reduces CO emissions in the outlet section of the flame tube (from 25‒28 ppm to 3.9‒4.6 ppm), while the emission of nitrogen oxides remains practically unchanged for the studied combustion chamber. Further research directions are proposed to enhance the working process efficiency of a dual-fuel combustion chamber for gas turbine engines as part of the power plant of FSPO vessels.

Opis:
The paper presents a new concept of the turbine engine in the area of pressure gain combustion (PGE). The engine works according to Humphrey’s cycle. Minor modification in construction has allowed power generation of 500 kW, 700 kW, 1000 kW, and 1800 kW. The concept successfully resolved the challenges related to the temporary opening and closing of the combustion chamber. The presented valve timing system has ensured effective gas flow and what stands behind it, an effective process of conversion of a high-pressure gas impulse into mechanical energy. Rotating combustion chambers enabled the application of an effective sealing system. The concept characterizes simple construction and potentially low power-to-weight coefficient. The CFD numerical analysis of the presented engine concept showed very promising effective efficiency and low specific fuel consumption.

Opis:
Currently, the world is facing problems regarding environmental pollution due to the combustion of fossil fuels. Generally, the combustion of fossil fuels takes place in the Internal Combustion engine for power or electricity generation. The combustion of fossil fuels emits greenhouse gases that lead to the greenhouse effect. The main symptom of the greenhouse effect is increased earth surface temperature. Also, the resources of fossil fuels are depleting rapidly and can take thousands of years to reproduce, so the time has come to go for lesser polluting renewable fuels. In this research, Bio-CNG is considered as an alternative fuel to conventional fuel, i.e. Diesel. The performance test on four-stroke IC Engines working on Bio-CNG and Diesel fuel is conducted simultaneously. The performance parameters such as Brake Power, Indicated Power, Thermal Efficiencies, Mechanical, Volumetric efficiency for both fuels are compared. Along with the performance, the emission is also recorded and compared. The results have shown that Bio-CNG has slightly less performance ability for similar engines working on Diesel fuel. Yet, this study also shows that Bio-CNG possesses the ability to replace the conventional fuel with some engine and exhaust system modifications. The higher calorific value (47000 kJ/kg) and lower or negligible carbon emission make it the best sustainable fuel substitute to conventional fuel, i.e. Diesel.

Opis:
Air pollution has a serious impact on the health of human beings and is a major cause of death worldwide every year. Out of the many sources of air pollution, the smoke generated from household combustion devices is very dangerous due to the incomplete combustion of fuel. Women from rural areas suffer a lot due to this harmful smoke. Diseases like cancer, throat, and lung infection occur in adults and children due to inhalation of this smoke. The traditional chulha used by rural women is operated by using cow dung, straw, and wood, and the air is blown manually by using small metallic pipes. This paper presents the design and development of an innovative stove to maximize flame temperature and minimize air pollution to overcome the health-related issues of rural women. A smokeless stove is presented, in which wood, straw, and cow dung are taken as primary fuel, and superheated steam as a secondary oxidizer for its operation. In this stove, a forced draft is created by the provision of a small fan, which is operated by solar power thus eliminating the need of creating a forced draft manually by the cook which makes this innovative stove superior to the traditional chulha. Owing to the provision of superheated steam, the flame temperature as well as the burning efficiency increases. The cooking time is reduced due to higher flame temperature as compared to the liquefied petroleum gas stove. The main objective of this work is to minimize air pollution and provide a smoke-free environment to the people using such devices as this innovative stove offers complete combustion of fuel. The flame temperature of the designed stove ranges from 595°C to 700°C and its thermal efficiency is 10–17% higher than that of the traditional chulha. The design of this stove is unique, and its maintenance cost is also much less.

The main objective of this study was to design a journal bearing, such that it can withstand the forces that arise in context to increasing the length of the shaft in an automotive turbocharger. The work will also provide information on how the design changes affect the overall performance of the bearing. The design changes include the thickness of the oil film, the number of grooves, the dimension of the grooves, the number of inlets and outlets, the dimension of the babbitt and mainly the length of the journal bearing. The simulation models were created using CATIA V5 and the analysis is done using ANSYS 19.2. The flow is considered to be laminar and is calculated using Reynold’s Equation. The new concept gave insight on how the design considerations affect the pressure distribution and the pressure developed. From the results, it was interpreted that the new design can withstand the four times the pressure while distributing the pressure over twice the original design.

Opis:
One group of plants commonly used for solids combustion are grate furnaces. These furnaces come in numerous design solutions, dedicated to fuels with different properties and plants with different capacities. The use of grate furnaces presents the as-yet unresolved challenge of how to ensure the most favourable air distribution along the length of the grate. The paper proposes a design solution to ensure proper air distribution along the length of the grate. An additional advantage of the proposed solution is the intensification of heat exchange in the furnace, enabling the boiler's circulating medium to be heated more efficiently. Both of the advantages allow an increase in the energy efficiency of the plant and therefore contribute to a reduction in the amount of fuel burned and CO2 emissions.

Opis:
The paper presents a concept of a new turbine engine with the use of rotating isochoric combustion chambers. In contrast to previously analyzed authors’ engine concepts, here rotating combustion chambers were used as a valve timing system. As a result, several practical challenges could be overcome. An effective ceramic sealing system could be applied to the rotating combustion chambers. It can assure full tightness regardless of thermal conditions and related deformations. The segment sealing elements working with ceramic counter-surface can work as self-alignment because of the centrifugal force acting on them. The isochoric combustion process, gas expansion, and moment generation were analyzed using the CFD tool (computational fluid dynamics). The investigated engine concept is characterized by big energy efficiency and simple construction. Finally, further improvements in engine performance are discussed.

Opis:
In this study, the mechanical losses of a single-cylinder spark-ignited Robin EY15 engine were experimentally determined and analysed by the indicated method. The effects of the load and speed on the mechanical loss balance were also analysed. The tests were conducted on a test bench equipped with a DC motor generator at speeds between 1500 and 4800 min-1 and three load levels of 25, 50, and 100%. The results showed that the mechanical efficiency ranges between 22.5% and 83.2% for the tested engine and the evaluated operation points, attaining the highest efficiency under the full load and 2100 min-1. However, at this load level, the efficiency is reduced to 29% with the increase in the rotation speed. Concurrently, the pumping losses contribute up to 58.7% of the total losses, which indicates that their contribution is even higher than the sum of the other components under low load conditions. However, as the load increases, this contribution decreases to 18% for lower rotation regimes. In addition, the experimental results of the total mechanical losses were compared with some numerical correlations found in the literature. Finally, some empirical correlations were proposed for the mechanical efficiency calculation of the tested engine.

Recent climate changes stimulate the search and introduction of solutions for the reduction of the anthropogenic effect upon the environment. Transition to the oxy-fuel combustion power cycles is an advanced method of CO2 emission reduction. In these energy units, the main fuel is natural gas but the cycles may also work on syngas produced by the solid fuel gasification process. This paper discloses a new highly efficient oxy-fuel combustion power cycle with coal gasification, which utilizes the syngas heat in two additional nitrogen gas turbine units. The cycle mathematics simulation and optimization result with the energy unit net efficiency of 40.43%. Parametric studies of the cycle show influence of the parameters upon the energy unit net efficiency. Change of the cycle fuel from natural gas to coal is followed by a nearly twice increase of the carbon dioxide emission from 4.63 to 9.92 gmCO2/kWh.

The paper presents optimization of the drive system in terms of adapting it to the characteristics of another engine. Powertrain parameters in a vehicle with an internal combustion engine were selected based on the following criteria: fuel consumption, engine dynamics, and emission standards for harmful substances. A light-duty passenger vehicle with gross vehicle weight rating (GVWR) of 3.5 tons was modified by replacing a spark-ignition engine with a diesel engine. The gear ratio in the powertrain had to be modified accordingly to optimize the engine’s performance, enhance engine dynamics, minimize fuel consumption and toxic emissions. The optimization of selected parameters of the vehicle driveline was performed based on the requirements of the standard NEDC and WLTC cycles.

Opis:
In the future, the simultaneous reduction of pollutant and CO2 emissions will require significantly enhanced powertrain functionalities that cannot only be adequately represented by the ICE (internal combustion engine) alone. Both automated transmissions and especially powertrain electrification can help to meet efficiently those extended requirements. The extended functionalities are no longer applied exclusively with the ICE itself ("Fully Flexible Internal Combustion Engine"), but distributed across the entire powertrain ("Fully Flexible Powertrain"). In addition, the powertrain will be fully networked with the vehicle environment and thus will utilize all data that are useful for emission and consumption-optimized operation of the ICE. Combustion engine and electrification often complement each other in a synergetic way. This makes it extremely sensible for the combustion engine to evolve in future from a "single fighter" to a "team player". If one compares the requirements of such an ICE with the definition of Industry 4.0, then there are extensive correspondences. Thus, it seems quite opportune to call such a fully networked combustion engine designed to meet future needs as “Internal Combustion Engine 4.0 (ICE 4.0)”. This even more so, as such a name can also be derived from the history: e.g. ICE 1.0 describes the combustion engines of the first mass-produced vehicles, ICE 2.0 the combustion engines emission-optimized since the 1960s and ICE 3.0 the highly optimized "Fully Flexible Combustion Engine", which currently offers a high torque and performance potential combined with low fuel consumption and pollutant emissions. In addition to further improvements in fuel consumption, the "Combustion Engine 4.0" offers such a low level of pollutant emissions that can best be described as "Zero Impact Emission". This means that such future ICE´s will no longer have a negative impact on the imission situation in urban areas. With the e-fuels topic, the ICE also has the potential to become both CO2- and pollutant-neutral in the medium and long term. This means that the ICE - also in passenger cars - will continue to be an essential and necessary cornerstone for future powertrain portfolios for the next decades.
