Download or read book Methods for Monitoring and Diagnosing the Efficiency of Catalytic Converters written by M. Sideris and published by Elsevier. This book was released on 1998-06-19 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic evolution of catalytic converters in the last thirty years was a result of a need worldwide to reduce pollution created by the exhaust gases of internal combustion engines. Environmental concerns have led American, Japanese and European Union (EU) legislation to pose continuously stricter emission limits for petrol engines in the last decades. The catalytic converter has become the most important means of exhaust treatment to achieve the desired emission limits. The international legislation has also created a need for a regular assessment of the efficiency of the catalytic converter in order to detect a deterioration of its conversion efficiency as soon as this deterioration takes place. The assessment of conversion efficiency of a catalytic converter can take place during normal driving of a vehicle (on-board diagnosis or OBD) or in a workshop by specialized technicians. The most important methods nowadays are the OBD methods. The evolution of methods concerned with OBD and non-OBD monitoring and diagnosing of efficiency of catalytic converters of internal combustion engines is described based on patents and published patent applications. Non-patent references are also used. The basic principles of modern catalytic converters are described in an extensive Introduction, where the importance of monitoring and diagnosing the efficiency of catalytic converters is demonstrated. The book is divided into four parts. The first part describes methods involving the use of oxygen or air/fuel exhaust gas sensors to determine the oxygen storage capacity of a catalytic converter. The second part describes methods involving the use of temperature sensors to determine the exothermic reaction capacity of a catalytic converter. The third part describes all other methods existing in patent literature that monitor and diagnose the efficiency of catalytic converters. The great majority of the methods of the third part involves exhaust gas concentration measurements. The fourth part comprises a general discussion of all methods described. In the beginning of each part, a short introduction is given to explain the problem that the methods attempt to solve. The methods in each part are presented in chronological order per patent applicant. This helps to evaluate how the patent applicant has improved his methods over time. A patent number index with information about the patent applicants, inventors, priorities and patent-families, an inventor index, a company index and a subject index can be found at the end of the book.

Download or read book Performance Exhaust Systems written by Mike Mavrigian and published by CarTech Inc. This book was released on 2014-08-15 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: To extract maximum performance, an engine needs an efficient, well-designed, and properly tuned exhaust system. In fact, the exhaust system's design, components, and materials have a large impact on the overall performance of the engine. Engine builders and car owners need to carefully consider the exhaust layout, select the parts, and fabricate the exhaust system that delivers the best performance for car and particular application. Master engine builder and award-winning writer Mike Mavrigian explains exhaust system principles, function, and components in clear and concise language. He then details how to design, fabricate, and fit exhaust systems to classic street cars as well as for special and racing applications. Air/exhaust-gas flow dynamics and exhaust system design are explained. Cam duration and overlap are also analyzed to determine how an engine breathes in air/fuel, as the exhaust must efficiently manage this burned mixture. Pipe bending is a science as well as art and you’re shown how to effectively crush and mandrel bend exhaust pipe to fit your header/manifold and chassis combination. Header tube diameter and length is taken into account, as well as the most efficient catalytic converters and resonators for achieving your performance goals. In addition, Mavrigian covers the special exhaust system requirements for supercharged and turbocharged systems. When building a high-performance engine, you need a high-performance exhaust system that’s tuned and fitted to that engine so you can realize maximum performance. This comprehensive book is your guide to achieving ultimate exhaust system performance. It shows you how to fabricate a system for custom applications and to fit the correct prefabricated system to your car. No other book on the market is solely dedicated to fabricating and fitting an exhaust system in high-performance applications.
Download or read book Materials Aspects in Automotive Catalytic Converters written by Hans Bode and published by Wiley-VCH. This book was released on 2002-06-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: MACC 2001 is the successor meeting of the first international conference on Materials Aspects in Automotive Catalytic Converters, MACC '97, and concentrates on the high-temperature mechanical and oxidation behaviour of both metal-supported and ceramic-supported automotive catalysts. The metal-supported catalyst is based on a ferritic steel with 5-8% aluminium, 17-22% chromium and small additions of reactive elements. More than 20,000,000 units were produced in 1999. The ceramic-supported catalytic converter is based on corderite. The production rate of ceramic-supported catalysts is much higher. Both materials have specific advantages and disadvantages which determine the application for a given car model. In addition to these two basic groups of catalytic carriers, the scope of the conference also refers to coating aspects, since the influence of the coating composition is becoming more and more important. The car and car-supplying industries report on their future requirements with respect to performance and service life. Maintaining good performance is mandatory particularly in the view of thinner supports and higher temperatures. Service life predictions, based on modelling and simulation techniques, will depend on reliable materials' data. This volume will therefore be invaluable to all scientists and engineers involved in the design and development of automotive catalysts.
