Design and Development of Tunable Exhaust Muffler for Race Car

2016-02-01
2016-28-0188
The Exhaust Noise is one of the major noise pollutants. It is well-known that for higher noise reduction, the engine has to bear high back pressure. For a race car, back-pressure plays a major role in engine's performance characteristics. For a given condition of engine rpm & load, conventional muffler has a fixed value of back-pressure and noise attenuation. Better acceleration requires low back-pressure, but the exhaust noise should also be less than the required (Norm) value (110 dBA). This contradicting condition is achieved here by using a ‘Butterfly Valve’ in this novel exhaust muffler. The butterfly valve assumes 2 positions i.e. fully open & fully closed. When the valve is fully closed, the noise reduction will be higher, but the back-pressure will also shoot up. When open, noise reduction will be less and so the back-pressure. So, when better performance is required, the valve is opened and back-pressure is reduced. The muffler is designed for a 4 cylinder 600 cc engine.

Relational Analysis, Guidelines for Estimating the High- and Low-Temperature Properties of Metals

2011-11-01
Relational analysis, defined as quantitative analysis of the relationships of high- and low-temperature properties in relation to their room-temperature values, provides a useful technique for estimating the properties of similar metals and alloys for which limited or no data are available. This book demonstrates how to use relational analysis methodology to extrapolate and estimate properties of metallic alloys at high temperatures from lower temperature data, and for estimating the properties of alloys for which scant property data exists. Data tables and graphs are presented for a wide range of aluminum alloys. Also shown, is how to apply relational analysis to other alloy systems including steels, magnesium alloys, and titanium alloys.

Tyre Recycling

2004-01-01
This is an expert overview on the topic of tire recycling. It summarizes current practices and the factors that have contributed to their growth and efficacy as viable, economically and environmentally sound methods of dealing with post-consumer tires. There are around 1 billion tires produced each year across the globe. It is estimated that for every tire sold another joins the waste stream. This publication explores innovative alternatives available to simply disposing of tires. In fact, waste tire products have many desirable properties in key application areas from thermoplastic elastomers to road surfaces. The primary area of study of this report is the EU, but reports from the US have also been cited. Statistics are incorporated from the EU markets, which illustrate changes in the industry since the inception of the European Tire Recycling Association a decade ago.

Solving Engineering Problems in Dynamics

2014-01-01
Solving Engineering Problems in Dynamics helps practicing engineers successfully analyze real mechanical systems by presenting comprehensive methods for analyzing the motion of engineering systems and their components. This analysis covers three basic phases: 1) composing the differential equation of motion; 2) solving the differential equation of motion; and 3) analyzing the solution. Although a formal engineering education provides the fundamental skills for completing these phases, many engineers nonetheless would benefit by gaining further insight in using these fundamentals to solve real-life engineering problems. This book thus describes in step-by-step order the methods related to each of these phases.

Technology for a Quieter America

2010-01-01
Exposure to noise at home, at work, while traveling, and during leisure activities is a fact of life for all Americans. As the population of the United States and, indeed, the world increases and developing countries become more industrialized, problems of noise are likely to become more pervasive and lower the quality of life for everyone. Efforts to manage noise exposures, to design quieter buildings, products, equipment, and transportation vehicles, and to provide a regulatory environment that facilitates adequate, cost-effective, sustainable noise controls require our immediate attention. This book, written for the engineering community; the public; government at the federal, state, and local levels; private industry; labor unions; and nonprofit organizations, looks at the most commonly identified sources of noise, how they are characterized, and efforts that have been made to reduce noise emissions and experiences.
