Knocking in Gasoline Engines
The book includes the papers presented at the conference discussing approaches to prevent or reliably control knocking and other irregular combustion events. The majority of today’s highly efficient gasoline engines utilize downsizing. High mean pressures produce increased knocking, which frequently results in a reduction in the compression ratio at high specific powers. Beyond this, the phenomenon of pre-ignition has been linked to the rise in specific power in gasoline engines for many years. Charge-diluted concepts with high compression cause extreme knocking, potentially leading to catastrophic failure. The introduction of RDE legislation this year will further grow the requirements for combustion process development, as residual gas scavenging and enrichment to improve the knock limit will be legally restricted despite no relaxation of the need to reach the main center of heat release as early as possible. New solutions in thermodynamics and control engineering are urgently needed to further increase the efficiency of gasoline engines.
International Conference on Ignition Systems for Gasoline Engines – International Conference on Knocking in Gasoline Engines
For decades, scientists and engineers have been working to increase the efficiency of internal combustion engines. For spark-ignition engines, two technical questions in particular are always in focus: 1. How can the air/fuel mixture be optimally ignited under all possible conditions? 2. How can undesirable but recurrent early and self-ignitions in the air/fuel mixture be avoided? Against the background of the considerable efficiency increases currently being sought in the context of developments and the introduction of new fuels, such as hydrogen, methanol, ammonia and other hydrogen derivatives as well as biofuels, these questions are more in the focus than ever. In order to provide a perfect exchange platform for the community of combustion process and system developers from research and development, IAV has organized this combined conference, chaired by Marc Sens. The proceedings presented here represent the collection of all the topics presented at the event and are thus intended to serve as an inspiration and pool of ideas for all interested parties.
6th International Conference on Ignition Systems for SI Engines – 7th International Conference on Knocking in SI Engines
In addition to the indisputably necessary electrification of the transport sector, which is currently being ramped up, internal combustion engines will still be urgently needed in the future. Otherwise, the demand for mobility in the on-road, off-road and non-road sectors cannot be met. There is no doubt that these internal combustion engines will have to be improved regarding efficiency plus lower emissions and nowadays more and more important upgraded for zero and low carbon fuels. Even though Spark Ignition (SI) engines have been around for more than a century, there is still a lot of room for improvement, particularly in terms of power density, ignition, combustion control, and preventing uncontrolled combustion. To offer all interested developers an inspiring exchange platform for the latest developments, IAV established two exciting conferences more than two decades ago, which are now held under the heading "Two Conferences - One Goal". This volume brings together the contributions to this conference.
Internal Combustion Engine Handbook
More than 120 authors from science and industry have documented this essential resource for students, practitioners, and professionals. Comprehensively covering the development of the internal combustion engine (ICE), the information presented captures expert knowledge and serves as an essential resource that illustrates the latest level of knowledge about engine development. Particular attention is paid toward the most up-to-date theory and practice addressing thermodynamic principles, engine components, fuels, and emissions. Details and data cover classification and characteristics of reciprocating engines, along with fundamentals about diesel and spark ignition internal combustion engines...
La connaissance de l'Islam dans l'Occident médiéval
This volume, the second in the series of Marie-Thérèse d’Alverny’s selected articles to be published by Variorum, gathers the majority of her studies on the understanding of Islam in the West from the early Middle Ages until the mid-13th century; some related works will be included in a further selection. In the 12th century, as she shows, a serious effort was for the first time made to learn something of the reality behind the fabulous and scurrilous stories about Muhammad and Islam. A collection of translations from Arabic, including the Koran, was commissioned in 1140 by Peter the Venerable of Cluny, and d’Alverny found the manuscript in which his secretary wrote these out. This discovery led her to explore other translations into Latin of the Koran and other Islamic texts, to identify the work of the translators Hermann of Carinthia, Robert of Ketton and Mark of Toledo, and to depict the milieu in which this work was possible.
The Palgrave Handbook of History and Social Studies Education
This Handbook presents an international collection of essays examining history education past and present. Framing recent curriculum reforms in Canada and in the United States in light of a century-long debate between the relationship between theory and practice, this collection contextualizes the debate by exploring the evolution of history and social studies education within their state or national contexts. With contributions ranging from Canada, Finland, New Zealand, Sweden, the Netherlands, the Republic of South Africa, the United Kingdom, and the United States, chapters illuminate the ways in which curriculum theorists and academic researchers are working with curriculum developers and educators to translate and refine notions of historical thinking or inquiry as well as pedagogical practice.
