Two-Stroke Engine - Repair and Maintenance

   As two-strokes fire every revolution, they are the most powerful engines for their size known. Highly tuned examples develop nearly two hp per cubic inch of displacement and run happily at 11,000-plus rpm. And with only three basic moving parts, two-strokes are the simplest and least expensive form of internal combustion. Yet, for many owners these little engines are contrivances from hell, cantankerous, difficult to start, and impossible to fix. Drive by a suburban neighborhood on trash collection day and you will find edgers, weed trimmers, and Chinese mini-bikes awaiting pickup at the curbside. The very simplicity of the two-stroke principle makes it unforgiving. Actually, these engines are easy to live with, if you have the background information and the tools to make a few simple diagnostic tests. And once past the fear of getting their hands dirty, most people find that fixing things is rewarding. Certainly it is more rewarding than spending $85 an hour (the current big-city shop rate) for someone else to do the work. Nor can we continue to discard products that no longer function as they should. That phase of American experience is behind us...

Handbook of Small Electric Motors

   The intent of this publication prepared by Wiiliam and Alan Yeadon is to provide necessary and valuable information on the design approaches, operating theory, practical design approaches, and the methods of manufacture for the most common motors that are in use today. The authors We have tried to meet the declared intent of the book by including as much information on small electric motors as possible. Though the universe of motor information is really huge, most of the available information is outdated. Thus, it is apparent that some information have had to be left out. As a result, this book will servse as a complete information source for the design, manufacture and application of small electric motors (less than 10 hp). It provides readers with the comprehensive induction to the basics of such motors and gives detailed coverage of 17+ types of electric motors and drives.

Fitness-for-Service and Integrity of Piping, Vessels, and Tanks

   This book is an exploration of failure in tanks, vessels, and pipes. This is done from an engineer's perspective, which means that it has to be usable to make run-or-repair decisions, to decide whether the component is still "fit for service," or whether it should be repaired or replaced. Fitness-for-service is the understanding of why, when, and how tanks vessels, and pipes fail. The answer is at the crossroads of mechanical design and analysis, metallurgy, welding, corrosion, inspection, and a good grasp of operations. These disciplines have to merge into a succinct and clear answer, preferably a single number: how much longer can the component operate safely. In answering this question, the engineer will have to rely on experience and science, and will have to reach a quantitative answer in the form of time to failure or margin to failure. This book is a modest addition to the many documents that address the interesting question of fitness-for-service. Foremost among publications dealing with the topic is the American Petroleum Institute's Recommended Practice API 579 Fitness for Service, a document which through its elegance, completeness, and practical value remains unmatched. The reader is urged to apply the API practice and other codes and standards referenced in the text, as they are the authoritative references to be used in making fitness-for-service and run-or-repair decisions.

Rudder Propeller and Hull Interaction by RANS

   In ail attempt to increase the safety at sea more attention has been focused on the requirements of the education of the officers sailing the ships and of the maneuverability of the sliips. Tliis has of course increased the interest in the numerical maneuvering simulators, which are a strong tool for investigation of the maneuverability of the ship and for the training of the crew members. Consequently, the increased interest lias resulted in stronger requirements of the quality, accuracy and reliability of the maneuvering models behind the simulators. The simulators are doing well today, but there are still areas where additional knowledge could be useful to improve the models. One of these areas is the interaction between the rudder, propeller and hull, which plays an important role for successful modeling of the maneuvering problem. Today the state of the art in maneuvering simulation covers the full mission simulators based on numerical solution of the equations of motion in conjunction with experimental hydrodynamic data which is mainly determined by means of captive model testing techniques like the planar motion mechanism (PMM). A study of the maneuvering model and the PMM model testing technique applied to the data generation revealed that a comprehensive set of experimental input data was required in order to perform a maneuvering simulation and model the rudder, propeller and hull interaction.

Shaft Grounding Rings - Protecting VFD Driven Motors from Bearing Currents

   When pulse width modulation (PWM) Variable Frequency Drives (VFDs) were developed using insulated gate bipolar transistors (IGBTs), this new technology was used to control electric induction motors in industrial and commercial applications. The advantages were obvious: Torque and motor speed could now be precisely controlled to optimize both process and energy requirements, The potential to save energy by operating motors at only the needed speed while maintaining torque requirements could potentially result in a 20% to 50% energy savings, Processes could be optimized and controlled by computer processing systems to achieve productivity increases or energy savings.

Dual-Fuel Diesel Engines

   The rate of consumption of the energy resources available continues to increase in spite of the significant progress being made to enhance the efficiency of their usage. Contributions to this increase in consumption include the rise in world population, improvements in the average standard of living, and the increase in average life expectancy. It is expected that the combustion of fossil fuels will continue to be the prime source to rely on for energy for some time to come. This will be constrained, however, by the continued depletion of crude petroleum resources of quality, the need for ever-cleaner exhaust emissions, and the rapid progress being made in the development of renewable resources. On the other hand, it is becoming increasingly evident, especially more recently, that the availability of natural gas, as well as other gaseous fuels, is increasing. This has come about mainly as a result of the improvements in the long-range transportation of gas and the increased availability of unconventional sources, such as those of shale gas, biogases, and coal bed-derived gases. Moreover, the increased exploitation of unconventional resources of liquid hydrocarbon fuels, such as tar sands, is bringing with it the potential production of large amounts of gaseous fuel mixtures, albeit of varied quality and having lower heating values than those of the conventional processed pipeline natural gas. On this basis, there are many opportunities to increasingly exploit such gaseous fuel resources while at the same time economizing on the consumption of other nonrenewable type liquid fossil fuel resources. Such approaches would need to develop further new means for the production of power while continuing the overall reduction of exhaust emissions, including those associated with their contribution to global warming.

Modelling and Observation of Exhaust Gas Concentrations for Diesel Engine Control

   In spite of the economic crisis of transport sectors such as the aerospace or naval, the automotive sector is facing a really challenging time. The trends in this sector during the past years had been focused on minimizing the pollutants, namely NOs, CO, HC or PM. However, the efforts in the next years are moving towards the C02 reduction, and thus minimizing the fuel consumption without worsening the pollutants. In the case of gasoline engines, the emissions problem is relatively solved since years by the three-way catalyst but for diesel, the use of different after-treatment systems as well as new combustion systems and control improvements are necessary. At the same time, the introduction of new fuel types and the development of the electric or hybrid vehicles introduce indeed new possibilities to the engineers. The diesel engine requires a renewal of the number of information sources available in order to monitor and control all the variables that affect the correct performance of this complex system. A good example is the on-board diagnostics algorithms necessary to monitor the NOx emissions, required for the urea dosing of the selective catalyst reduction systems or useful for the development of direct NOs control. Within this framework, this book intends to give solutions to real problems on the topic of the online estimation of the exhaust engine variables in diesel engines. The reader will find a number of methods and algorithms that cover the main possibilities for inferring the exhaust variables on-board...

Pumping Machinery Theory and Practice

   The consumption of energy taking place in pumping systems accounts for approximately twenty per cent of the world's electrical energy demand. Moreover, the operational cost of pumping machinery tar outweighs their capital cost. Accordingly, engineers strive for optimum equipment performance for achieving economic operation, and a thorough understanding of the components and operating principles of these machines will provide an opportunity to dramatically reduce energy, as well as operational and maintenance costs. Reducing energy consumption will also complement the current thrust towards protecting our environment. This book is intended to be a basic reference on theoretical foundation and applications of various types of pumping machinery. In view of the great importance of pumps and compressors in almost every engineering system, this book presents the fundamental concepts underlying the flow processes taking place in these machines and the transformation of mechanical energy into fluid power. Special emphasis is given to basic theoretical formulation and design considerations of pumps and compressors in addition to improving problem-solving skills. This is achieved through the presentation of solved examples of applied nature using analytical means and/or basic engineering practices. The book consists of ten chapters covering two main themes: the first smoothly introduces the essential terminology, basic principles, design considerations, and operational-type problems in pumping machinery. This part is supported by a good number of worked examples plus problems at the end of each chapter for the benefit of senior undergraduate students and junior engineers. This is considered a key feature of this book because other books in this area rarely provide enough worked problems and exercises. The second theme focuses on advanced topic such as two-phase flow pumping systems targeting practicing field engineers and introductory research scientists.

Compressed Air Operations Manual

   The purpose of this book is to provide a basic understanding of the compressed air systems, equipment, and technologies that are available on the market today. You might have many years of experience with a specific compression system, but the catalogs and sales literature just aren't providing you with the information you need. Maybe you've just been assigned the compression system as part of your responsibilities and you have no experience whatsoever with this type of equipment. Oftentimes, the compressors are the bastard child of a company's capital equipment and no one in particular is responsible for them. If you head up the company's maintenance department, the compressors probably fall under your responsibilities. You may be a salesman who works with pneumatic-powered equipment and, from time to time, are asked to comment on your customer's compression systems. In any case, this book will give you the baseline information that will allow you to make well-informed decisions about specifying, expanding, or assessing a compression system. Like many technical people, I felt that I had a clear conceptual understanding of air compression, I mean, what's to know? You suck in some air, you smash it into a tank. Simple! I even built an air compressor from an old auto AC pump and a piece of pipe when I was in high school.юю

Fire Pump Handbook

   NFPA 25 was introduced in 1992 to promote these activities and certain sections specifically pertain to fire pumps. NFPA recognizes that an installation standard such as NFPA 20 or maintenance document such as NFPA 25 must be suitable for enforcement and, as a result, must be concise and without explanatory text. Additionally, it must be acknowledged that such standards cannot be written to cover every situation that could be encountered. Therefore, NFPA 20 and NFPA 25 must be applied with judgment, the application of good sense, and an awareness of the rationale for the requirements. To assist in this task, NFPA, in partnership with the NFSA, has developed the Fire Pump Handbook. The present publication is intended to provide users of NFPA 20 and applicable portions of NFPA 25 with background information on certain requirements. The book also contains some suggestions on how certain provisions of the standards can be implemented effectively. The contents of the handbook are intended to provide users of NFPA 20 and NFPA 25 with a better understanding and appreciation of the documents. However, the reader is cautioned to look upon the commentary and other supporting information as views of the editors and contributing authors. Only the contents of NFPA 20 and NFPA 25 are considered the official position of NFPA.

The Coen & Hamworthy Combustion Handbook

   The last Coen & Hamivorthy Combustion Handbook was written by Arthur H. Light in 1920.' In the late 1980s, Coen authorized the publication of a new combustion handbook at the request of its customers, but day-to-day work never allowed time for the book. The origins of this book started during a business trip. In early 2000, one of the editors (Steve) was on a trip to visit a major Coen customer with a young Coen application engineer. During dinner, the engineer told Steve a story of a number of engineers debating the units of molecular weight for hours. It was at this moment that Steve decided a unique kind of book was needed that did not exist for combustion engineers. The book needed to be all inclusive and cover the very basics in building block form up to more complex combustion topics for everyone involved in combustion systems to use. This book is designed for all engineers and professionals involved in the field of industrial and utility combustion systems. It is roughly divided into two parts, consisting of a total of 17 chapters, sequentially covering relevant and important combustion engineering basics and then specific computations and applications. Each chapter is roughly organized from simple to more complex, thus allowing the reader to absorb as much as they may need before moving on to the next chapter. Practical examples are also included.
