Download or read book Numerical and Experimental Investigation of Water Introduction Into DI Diesel Engine Combustion written by Peter Eckert and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Im vorliegenden Band 3/2008 berichtet Herr Eckert uber die Ergebnisse aus Untersuchungen zur Partikel- und Stickoxidminimierung bei Dieselmotoren durch Wassereinbringung. Das primare Ziel ist dabei die innermotorische Reduzierung der thermischen Stickoxidbildung. Es sind unterschiedliche Methoden der wassereinbringung in den dieselmotorischen Verbrennungsprozess moglich; beispielsweise die Einspritzung von Wasser in das Ansaugsystem, eine direkte Einspritzung von Wasser in den Brennraum sowie die Wassereinbringung mit Diesel- Wasser Emulsionen. Diese Massnahmen sind unter anderem bei dieselmotoren, die zumindest teilweise mit Schwerol betrieben werden, besonders interessant, da dort klassische Methoden zur Schadstoffreduktion, wie z.B. Abgasruckfuhrung oder Abgasnachbehandlung, nur mit erheblichem Aufwand eingesetzt werden konnen.
Book Synopsis Experimental Investigation of Transient RCCI Combustion in a Light Duty Diesel Engine by :

Available in PDF, EPUB and Kindle. Book excerpt: Low Temperature Combustion (LTC) is currently being researched as a way to reduce problematic emissions (i.e., NOx and PM) from compression-ignition engines while maintaining high fuel efficiency. One of the primary types of LTC is Premixed Compression Ignition (PCI), with some examples of PCI being homogeneous charge compression ignition (HCCI), premixed charge compression ignition (PCCI), reactivity controlled compression ignition (RCCI) and partially premixed combustion (PPC). These LTC strategies use early fuel injections to allow sufficient time for air/fuel mixing before combustion. By increasing the amount of air/fuel premixing, NOx and PM emissions can be lowered due to the reduced local and global equivalence ratios. The lean nature of PCI also maintains high thermal efficiency due to the reduced heat transfer losses from the reduced peak combustion temperatures. However, too much air/fuel premixing can lead to rapid energy release rates, limiting the operation space for PCI. To combat this problem, the combustion strategy of interest for the study, RCCI, uses fuel reactivity gradients to increase combustion duration (i.e., reduce the energy release rate) and phasing control, thereby increasing the engine operating space for PCI operation. Previous tests [1-7] have shown promising results for petroleum-based fuels with RCCI. Recent work at Oak Ridge National Laboratory (ORNL) has shown how blends of biofuels with petroleum fuels can improve RCCI combustion performance [8,9] The work sets out to examine biofuel performance over a wide engine operating space both at steady-state and transient operating conditions with RCCI combustion. It is hoped to demonstrate the capability and effects of using bio-derived fuels in place of conventional petroleum-derived fuels for advanced combustion strategies under real-world operating conditions. In RCCI operation, blends of biodiesel and ethanol fuels will be investigated to examine the fuel effects on the combustion event.
Book Synopsis Development of a Partially Premixed Combustion Model for a Diesel Engine Using Multiple Injection Strategies by : Rene Thygesen
Download or read book Development of a Partially Premixed Combustion Model for a Diesel Engine Using Multiple Injection Strategies written by Rene Thygesen and published by Logos Verlag Berlin GmbH. This book was released on 2012 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to fulfil future emissions legislations, new combustion systems are to be investigated. One way of improving exhaust emissions is the application of multiple injection strategies and conventional or partially premixed combustion conditions to a Diesel engine. The application of numerical techniques as CFD supports and improves the quality of engine developments. Unfortunately, current spray and combustion models are not accurate enough to simulate multiple injection systems, being in this way a topic of research. The goal of this study was the development of a novel simulation method for the investigation of Diesel engines operated with multiple injection strategies and different combustion modes. The first part of this work focused in improving the spray modelling. The inform ation of 3D CFD simulations of the injector nozzle was introduced in the spray simulation as boundary conditions developing coupling subroutines for this issue. The atomisation modelling was also improved using validated presumed droplet size distributions. Moreover, to avoid the simulation of the injector nozzle for every investigated operating point, a novel interpolating tool was developed in order to create spray boundary conditions based on few 3D CFD simulations of the nozzle under certain initial and boundary conditions. The second part of this thesis dealt with the combustion modelling of Diesel engines. For this issue, a laminar flamelet approach called Representative Interactive Flamelet model (RIF) was selected and implemented. Afterwards, an extended combustion model based on RIF was developed in order to take into account multiple injection strategies. Finally, this new model was validated with a wide range of operating points: applying multiple injection strategies under conventional and partially premixed combustion conditions.

Download or read book Lean Combustion written by Derek Dunn-Rankin and published by Academic Press. This book was released on 2011-07-28 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion under sufficiently fuel-lean conditions can have the desirable attributes of high efficiency and low emissions, this being particularly important in light of recent and rapid increases in the cost of fossil fuels and concerns over the links between combustion and global climate change. Lean Combustion is an eminently authoritative, reference work on the latest advances in lean combustion technology and systems. It will offer engineers working on combustion equipment and systems both the fundamentals and the latest developments in more efficient fuel usage and in much-sought-after reductions of undesirable emissions, while still achieving desired power output and performance. This volume brings together research and design of lean combustion systems across the technology spectrum in order to explore the state-of-the-art in lean combustion and its role in meeting current and future demands on combustion systems. Readers will learn about advances in the understanding of ultra lean fuel mixtures and how new types of burners and approaches to managing heat flow can reduce problems often found with lean combustion such as slow, difficult ignition and frequent flame extinction. The book will also offer abundant references and examples of recent real-world applications. Covers all major recent developments in lean combustion science and technology, with new applications in both traditional combustion schemes as well as such novel uses as highly preheated and hydrogen-fueled systems Offers techniques for overcoming difficult ignition problems and flame extinction with lean fuel mixtures Covers new developments in lean combustion using high levels of pre-heat and heat re-circulating burners, as well as the active control of lean combustion instabilities

Download or read book An Experimental Investigation of Diesel-ignited Gasoline and Diesel-ignited Methane Dual Fuel Concepts in a Single Cylinder Research Engine written by Umang Dwivedi and published by . This book was released on 2013 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel-ignited gasoline and diesel-ignited methane dual fuel combustion experiments were performed in a single-cylinder research engine (SCRE), outfitted with a common-rail diesel injection system and a stand-alone engine controller. Gasoline was injected in the intake port using a port-fuel injector, whereas methane was fumigated into the intake manifold. The engine was operated at a constant speed of 1500 rev/min, a constant load of 5.2 bar IMEP, and a constant gasoline/methane energy substitution of 80%. Parameters such as diesel injection timing (SOI), diesel injection pressure, and boost pressure were varied to quantify their impact on engine performance and engineout ISNOx, ISHC, ISCO, and smoke emissions. The change in combustion process from heterogeneous combustion to HCCI like combustion was also observed.
