Automobile Catalytic Converters


Book Description

The use of catalytic converters for the purification of automotive exhaust gases is a relatively new technology which was brought into existence by social pressures for the preservation of acceptable environmental conditions. The majority of catalytic practitioners have been able to watch the growth of this technology from its inception to its current state of sophistication. Automotive catalytic converter technology is now in a mature state, and this chapter from Vol. 5 Catalysis: Science and Technology by Dr. K. C. Taylor provides a review which covers both the process chemistry and the most important converter design factors. Contents 1. Introduction. . . . . . . . . . . . . . 2.

Performance Exhaust Systems


Book Description

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.




Chemistry 2e


Book Description

Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition.




Social Murder


Book Description

“Ronni’s mind fell completely silent. She stopped being aware of the room around her, there was only the hateful figure of a bully and an abuser ahead of her, all else was a blur.” You’re in a strange city. Your friend is missing. Could you find the courage to do what is necessary? Would you even know where to start? These are the questions faced by law graduate Ronni Wong when her friend Jenny disappears after a date with a man she met online. Finding evidence suggesting that Jenny’s internet lover hides the darkest of secrets, Ronni is forced to embark on a journey through social media to discover the identity of a kidnapper, and then a dangerous race against time through the streets of Metro Manila to save her friend’s life. The clock is ticking, can Ronni make it in time? Join Ronni as her investigation into one disappearance leads her into mortal danger. Social Murder will keep you on the edge of your seat, and at the same time challenge you to think about how you use social media. Are you safe online?




Taking Stock of Industrial Ecology


Book Description

How can we design more sustainable industrial and urban systems that reduce environmental impacts while supporting a high quality of life for everyone? What progress has been made towards reducing resource use and waste, and what are the prospects for more resilient, material-efficient economies? What are the environmental and social impacts of global supply chains and how can they be measured and improved? Such questions are at the heart of the emerging discipline of industrial ecology, covered in Taking Stock of Industrial Ecology. Leading authors, researchers and practitioners review how far industrial ecology has developed and current issues and concerns, with illustrations of what the industrial ecology paradigm has achieved in public policy, corporate strategy and industrial practice. It provides an introduction for students coming to industrial ecology and for professionals who wish to understand what industrial ecology can offer, a reference for researchers and practitioners and a source of case studies for teachers.

Moving Violations


Book Description

The first comprehensive history of auto regulation in the United States. Regulation has shaped the evolution of the automobile from the beginning. In Moving Violations, Lee Vinsel shows that, contrary to popular opinion, these restrictions have not hindered technological change. Rather, by drawing together communities of scientific and technical experts, auto regulations have actually fostered innovation. Vinsel tracks the history of American auto regulation from the era of horseless carriages and the first, faltering efforts to establish speed limits in cities to recent experiments with self-driving cars. He examines how the government has tried to address car-related problems, from accidents to air pollution, and demonstrates that automotive safety, emissions, and fuel economy have all improved massively over time. Touching on fuel economy standards, the rise of traffic laws, the birth of drivers' education classes, and the science of distraction, he also describes how the government's changing activities have reshaped the automobile and its drivers, as well as the country's entire system of roadways and supporting technologies, including traffic lights and gas pumps. Moving Violations examines how policymakers, elected officials, consumer advocates, environmentalists, and other interested parties wrestled to control the negative aspects of American car culture while attempting to preserve what they saw as its positive contributions to society. Written in a clear, approachable, and jargon-free voice, Moving Violations will appeal to makers and analysts of policy, historians of science, technology, business, and the environment, and any readers interested in the history of cars and government.
