Book excerpt: Engine knock is, as is known, preceded by normal burning of the first part of the charge, and only the part burned last (residual charge), knocks. The aim of the present measurements was, first, to reexamine the combustion form in this residual charge, because of the absence of uniform and frequently contradictory results in the very extensive literature on the subject. On top of that, an attempt was to be made to gain a deeper insight into the mechanism accompanying the combustion process, by means of the electrical test equipment perfected in recent years.

Download or read book Knocking in Gasoline Engines written by Michael Günther and published by Springer. This book was released on 2017-11-21 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book International Conference on Ignition Systems for Gasoline Engines International Conference on Knocking in Gasoline Engines written by Marc Sens and published by expert verlag GmbH. This book was released on 2022-10-17 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Innovation and the Development of Flight written by Roger D. Launius and published by Texas A&M University Press. This book was released on 1999 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perhaps no technological development in the century has more fundamentally transformed human life than the airplane and its support apparatus. The nature of flight, and the activities that it has engendered throughout the world, makes the development of aviation technology an important area of investigation. Why did aeronautical technology take the shape it did? Which individuals and organizations were involved in driving it? What factors influenced particular choices of technologies to be used? More importantly, how has innovation affected this technology? Innovation and the Development of Flight, a first strike at the "new aviation history," represents a significant transformation of the field by relating the subject to larger issues of society, politics, and culture, taking a more sophisticated view of the technology that few historians have previously attempted. This volume moves beyond a focus on the artifact to emphasize the broader role of the airplane and, more importantly, the entire technological system. This suggests that many unanswered questions are present in the development of modern aviation and that inquisitive historians seek to know the relationships of technological systems to the human mind. Some of the subjects discussed are early aeronautical innovation and government patronage; the evolution of relationships among airports, cities, and industry; the relationship of engine development to the entire aviation industry; the Department of Commerce's influence on light plane development; pressure in the Air Force for the development of jet engines; and lessons of the National Aerospace Plane Program. Aviation historians and historians of technology will find Innovation and the Development of Flight a valuable examination of aeronautical innovation providing foundations for continued explorations of this field.

Download or read book A Phenomenological Knock Model for the Development of Future Engine Concepts written by Alexander Fandakov and published by Springer. This book was released on 2018-12-28 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of 0D/1D knock models available today are known for their poor accuracy and the great effort needed for their calibration. Alexander Fandakov presents a novel, extensively validated phenomenological knock model for the development of future engine concepts within a 0D/1D simulation environment that has one engine-specific calibration parameter. Benchmarks against the models commonly used in the automotive industry reveal the huge gain in knock boundary prediction accuracy achieved with the approach proposed in this work. Thus, the new knock model contributes substantially to the efficient design of spark ignition engines employing technologies such as full-load exhaust gas recirculation, water injection, variable compression ratio or lean combustion. About the Author Alexander Fandakov holds a PhD in automotive powertrain engineering from the Institute of Internal Combustion Engines and Automotive Engineering (IVK) at the University of Stuttgart, Germany. Currently, he is working as an advanced powertrain development engineer in the automotive industry.
Download or read book Thermodynamics and Heat Powered Cycles written by Chih Wu and published by Nova Publishers. This book was released on 2007 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the rapid advances in computer technology, intelligent computer software and multimedia have become essential parts of engineering education. Software integration with various media such as graphics, sound, video and animation is providing efficient tools for teaching and learning. A modern textbook should contain both the basic theory and principles, along with an updated pedagogy. Often traditional engineering thermodynamics courses are devoted only to analysis, with the expectation that students will be introduced later to relevant design considerations and concepts. Cycle analysis is logically and traditionally the focus of applied thermodynamics. Type and quantity are constrained, however, by the computational efforts required. The ability for students to approach realistic complexity is limited. Even analyses based upon grossly simplified cycle models can be computationally taxing, with limited educational benefits. Computerised look-up tables reduce computational labour somewhat, but modelling cycles with many interactive loops can lie well outside the limits of student and faculty time budgets. The need for more design content in thermodynamics books is well documented by industry and educational oversight bodies such as ABET (Accreditation Board for Engineering and Technology). Today, thermodynamic systems and cycles are fertile ground for engineering design. For example, niches exist for innovative power generation systems due to deregulation, co-generation, unstable fuel costs and concern for global warming. Professor Kenneth Forbus of the computer science and education department at Northwestern University has developed ideal intelligent computer software for thermodynamic students called CyclePad. CyclePad is a cognitive engineering software. It creates a virtual laboratory where students can efficiently learn the concepts of thermodynamics, and allows systems to be analyzed and designed in a simulated, interactive computer aided design environment. The software guides students through a design process and is able to provide explanations for results and to coach students in improving designs. Like a professor or senior engineer, CyclePad knows the laws of thermodynamics and how to apply them. If the user makes an error in design, the program is able to remind the user of essential principles or design steps that may have been overlooked. If more help is needed, the program can provide a documented, case study that recounts how engineers have resolved similar problems in real life situations. CyclePad eliminates the tedium of learning to apply thermodynamics, and relates what the user sees on the computer screen to the design of actual systems. This integrated, engineering textbook is the result of fourteen semesters of CyclePad usage and evaluation of a course designed to exploit the power of the software, and to chart a path that truly integrates the computer with education. The primary aim is to give students a thorough grounding in both the theory and practice of thermodynamics. The coverage is compact without sacrificing necessary theoretical rigor. Emphasis throughout is on the applications of the theory to actual processes and power cycles. This book will help educators in their effort to enhance education through the effective use of intelligent computer software and computer assisted course work.
