Book Synopsis Emission Reduction with an Alternative Diesel Combustion Process by : Marvin Sascha Wahl
Download or read book Emission Reduction with an Alternative Diesel Combustion Process written by Marvin Sascha Wahl and published by Springer Nature. This book was released on 2023-07-29 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marvin Sascha Wahl presents the possibilities for optimising diesel engine combustion. In the advanced process of partially premixed diesel combustion, nitrogen oxide and soot emissions can be minimised at the same time. A new feature is the possibility of applying this strategy up to 2000 revolutions and 10 bar indicated mean pressure. In this work, various effective parameters are also compared and correlated with each other. A final comparison with conventional diesel combustion shows the advantages and disadvantages and evaluates them.
Book Synopsis A Simulative Approach to Predict Energy Consumption of Future Powertrain Configurations for the Year 2040 by : Tobias Stoll
Download or read book A Simulative Approach to Predict Energy Consumption of Future Powertrain Configurations for the Year 2040 written by Tobias Stoll and published by Springer Nature. This book was released on 2023-07-29 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the simulative prediction of efficiency and CO2-emissions of future powertrain systems for the year 2040. For this purpose, a suitable simulation environment is first created. This is followed by a technology extrapolation of all relevant powertrain systems, for example: combustion engines, electric drives, fuel cells as well as all relevant additional components. These components are then used to build 57 vehicle variants for the simulation. Finally, extensive simulations of the vehicle variants are carried out, evaluated and compared. Comprehensive tables of results are available for all simulated vehicle variants. The evaluations are of interest to anyone concerned with energy consumption and CO2-emissions of future vehicles.
Book Synopsis Analysis of Injection Processes in an Innovative 3D-CFD Tool for the Simulation of Internal Combustion Engines by : Marlene Wentsch
Download or read book Analysis of Injection Processes in an Innovative 3D-CFD Tool for the Simulation of Internal Combustion Engines written by Marlene Wentsch and published by Springer. This book was released on 2018-05-16 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the large number of influencing parameters and interactions, the fuel injection and therewith fuel propagation and distribution are among the most complex processes in an internal combustion engine. For this reason, injection is usually the subject to highly detailed numerical modeling, which leads to unacceptably high computing times in the 3D-CFD simulation of a full engine domain. Marlene Wentsch presents a critical analysis, optimization and extension of injection modeling in an innovative, fast response 3D-CFD tool that is exclusively dedicated to the virtual development of internal combustion engines. About the Author Marlene Wentsch works as research associate in the field of 3D-CFD simulations of injection processes at the Institute of Internal Combustion Engines and Automotive Engineering (IVK), University of Stuttgart, Germany.
Book Synopsis Modeling of Real Fuels and Knock Occurrence for an Effective 3D-CFD Virtual Engine Development by : Francesco Cupo
Download or read book Modeling of Real Fuels and Knock Occurrence for an Effective 3D-CFD Virtual Engine Development written by Francesco Cupo and published by Springer Nature. This book was released on 2020-09-14 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: To drastically reduce the emission of greenhouse gases, the development of future internal combustion engines will be strictly linked to the development of CO2 neutral fuels (e.g. biofuels and e-fuels). This evolution implies an increase in development complexity, which needs the support of engine 3D-CFD simulations. Francesco Cupo presents approaches to accurately describe fuel characteristics and knock occurrence in SI engines, thus improving the current simulation capability in investigating alternative fuels and innovative combustion processes. The developed models are successfully used to investigate the influence of ethanol-based fuels and water injection strategies on knock occurrence and to conduct a virtual fuel design for and engine operating with the innovative SACI combustion strategy.
Book Synopsis An Innovative 3D-CFD-Approach towards Virtual Development of Internal Combustion Engines by : Marco Chiodi
Download or read book An Innovative 3D-CFD-Approach towards Virtual Development of Internal Combustion Engines written by Marco Chiodi and published by Springer Science & Business Media. This book was released on 2011-03-07 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the engine development process, simulation and predictive programs have continuously gained in reliance. Due to the complexity of future internal combustion engines the application of simulation programs towards a reliable “virtual engine development” is a need that represents one of the greatest challenges. Marco Chiodi presents an innovative 3D-CFD-tool, exclusively dedicated and optimized for the simulation of internal combustion engines. Thanks to improved or newly developed 3D-CFD-models for the description of engine processes, this tool ensures an efficient and reliable calculation also by using coarse 3D-CFD-meshes. Based on this approach the CPU-time can be reduced up to a factor 100 in comparison to traditional 3D-CFD-simulations. In addition an integrated and automatic “evaluation tool” establishes a comprehensive analysis of the relevant engine parameters. Due to the capability of a reliable “virtual development” of full-engines, this fast response 3D-CFD-tool makes a major contribution to the engine development process. Südwestmetall-Förderpreis 2010

Book Synopsis AN EXPERIMENTAL STUDY ON THE IMPACT OF WATER INJECTION ON THE PERFORMANCE AND EMISSIONS OF A NATURAL GAS - DIESEL PILOT ENGINE by :
Download or read book AN EXPERIMENTAL STUDY ON THE IMPACT OF WATER INJECTION ON THE PERFORMANCE AND EMISSIONS OF A NATURAL GAS - DIESEL PILOT ENGINE written by and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Natural gas has been gaining popularity as an alternative fuel due to its high availability, low CO2 emissions, and low cost. In this experimental study, water injection's impact on medium and heavy-duty engine operation fueled by natural gas and pilot diesel injection for ignition was studied under stochiometric operation for use with a three-way catalytic converter to meet criteria emissions for off-road power generation. To retain high efficiencies, a high compression ratio of 17.3:1 was used. Maintaining stoichiometric operation with a high compression ratio leads to combustion knock, pre-ignition, and high NOx formation. Conventionally, cooled EGR can be used to reduce NOx, but results in increased soot and does not eliminate combustion knock and pre-ignition. As an alternative to EGR this work utilized port injected water to provide on demand charge cooling, successfully reducing both NOx and soot while enabling high-load operation. A combination of both high and low speeds and loads were tested to study the impact of water injection on the emissions and performance of the natural gas, diesel-pilot engine. Additionally, water injections impact on diesel only operation was tested to provide comparison metrics and aid in a better understanding of the mechanisms at work when injecting water in an internal combustion engine. At full load, 16.8 bar BMEP, it was found that a water to fuel ratio of 0.5:1 was sufficient to enabling the knock free operation without significant increase in combustion duration or instability where operating at this load without water resulted in pre-ignition. Increasing the water to fuel ratio to 1:1 enabled a 21 bar BMEP load. At 12.5 bar BMEP, the NOx emission was reduced from 13.5 g/kwh to 7.2 g/kwh with a water to fuel mass ratio of 1.5:1. In addition to solving the high NOx and pre-ignition problem, a water to fuel ratio of 2.5:1 at 16.8 bar BMEP also decreased the soot content in the exhaust by a factor of 3.5 with only a small penalty in efficiency, decreasing break thermal efficiency from 41 to 40%.
