The electric vehicle industry - land, water and air - is rapidly rising to become a huge market of over $290 billion by 2024. Some run entirely on harvested energy as with solar lake boats. Others recycle energy as with regenerative braking of cars, buses and military vehicles harvesting kinetic energy. Others use different forms of harvesting either to charge the traction batteries or to drive autonomous devices as we progress to the wireless vehicle. In some cases, harvesting is making completely new forms of electric vehicle possible such as "glider" Autonomous Underwater Vehicles (AUVs) that stay at sea for years and surface to gain electricity from both wave power and sunshine whenever necessary. Indeed, multiple forms of energy harvesting on one vehicle is becoming much more common from cars to superyachts. This report is the first to provide technical and marketing analysis of the rapidly growing market for energy harvesting in electric vehicles - land, water and air - with forecasts.

All electric vehicles have at least one traction motor, so the market for electric vehicle traction motors is one of the largest markets for electric vehicle parts and a primary determinant of the performance and affordability of a given vehicle. Indeed, IDTechEx Research finds that in 2013 44.6 million electric motors will be needed for vehicles, rising to 147.7 million in 2023. Today, the motors that propel electric vehicles on land, through water and in the air are mainly brushless because brushed commutator motors are on the way out. Most of the number and the value of those brushless traction motors lies in permanent magnet synchronous ones, notably Brushless DC "BLDC", a form with trapezoidal waveform, and Permanent Magnet AC "PMAC", a type with a sinusoidal waveform. No matter: they both have excellent performance including simple provision of reverse and regenerative braking. However, that dominance is about to change. The main reason is not those well publicized but elusive in-wheel motors coming in at two to six per vehicle but simply the move to much larger vehicles and therefore motors.

The exhaust and after-treatment market is set for considerable growth. The tightening regulatory environment has led to considerably increased revenues per vehicle and this is set to improve globally as emerging high-growth markets catch up with Europe and Northern America in terms of the level of equipment needed to meet regulations. The costly situation where different national and regional regulation and testing regimes that have required different emissions technologies and systems is being steadily eroded by the harmonization of emissions regulations. Having initially endured the difficult situation of meeting environmental regulations developed across different markets, OEMs and suppliers have found that emerging markets have largely been able to pick their regulation ’off the shelf’. This has meant that those suppliers that have successfully developed technology to meet those regulations enjoy a competitive advantage in the emerging markets. This fourth edition examines the key drivers in this sector including fuel economy and CO2 emissions, noxious emissions and health concerns and platinum group metal trends.

Conventional fossil fuels will constitute the majority of automotive fuels for the foreseeable future but will have to adapt to changes in engine technology. Unconventional transport fuels such as biofuels, gas-to-liquid fuels, compressed natural gas, and liquid petroleum gas will also play a role. Hydrogen might be a viable transport fuel if it overcomes barriers in production, transport, storage, and safety and/or if fuel cells become viable. This book opens by considering these issues and then introduces practical transport fuels. A chapter on engine deposits follows, which is an important practical topic about how fuels affect engines that is not usually considered in other books. The next three chapters discuss auto-ignition phenomena in engines. The auto-ignition resistance of fuels is the most important fuel property since it limits the efficiency of spark ignition engines and determines the performance of compression ignition engines. Moreover, the manufacture of fuels is primarily driven by the need to meet auto-ignition quality demands set by fuel specifications.

This report looks at the market drivers currently affecting the advanced powertrain sector, in particular fuel economy, CO2 emissions, and fuel prices. Furthermore, the report provides detailed analysis of spark-ignition, compression-ignition and combined spark and compression ignition engines technologies. Powertrain has always been perhaps the single most critical aspect of the automotive engineering; the decision taken in the early years of the 20th century to concentrate on internal combustion engines (ICE) rather than electric traction or sterling cycle heat engines has meant that throughout the last century development of ICE was absolutely critical, not only for the competitive aspects of the automotive and commercial vehicle industries, but also in terms of much of the military and civilian aircraft sectors, marine and stationary engines. As one well-known commentator on technology once said, “if as much research and development resource had been devoted to the sterling cycle engine as has been invested in the ICE, we would all be driving around in vehicles powered by external heat engines”.

In the six years since the last edition of this report, the use of pressure charging techniques has expanded dramatically, and the number of applications has continued to grow. What we have seen in recent years is the ascendancy of the turbocharger and its use by almost every major manufacturer, as well as the adoption of new arrangements that combine turbocharger and supercharger technologies to deliver characteristics superior to what either technology could deliver individually. The global demand for turbochargers is rising fast; there are a number of key market drivers fuelling this growth, namely tightening regulation governing emissions and fuel efficiency, the high price of fuel, and the popularity of direct injection petrol and diesel-powered cars. The trend towards engine downsizing for improved fuel efficiency and lower emissions continues to gain pace, leading to increasing demand for turbocharging for petrol engines. The changing regulatory environment is challenging automakers across the globe to create cleaner, more fuel efficient vehicles that are also able to satisfy the performance requirements of demanding consumers.

A kinetic energy recover system (KERS) captures the kinetic energy that results when brakes are applied to a moving vehicle. The recovered energy can be stored in a flywheel or battery and used later, to help boost acceleration. KERS helps transfer what was formerly wasted energy into useful energy. In 2009, the Federation Internationale de l’Automobile (FIA) began allowing KERS to be used in Formula One (F1) competition. Still considered experimental, this technology is undergoing development in the racing world but has yet to become mainstream for production vehicles. The Introduction of this book details the theory behind the KERS concept. It describes how kinetic energy can be recovered, and the mechanical and electric systems for storing it. Flybrid systems are highlighted since they are the most popular KERS developed thus far. The KERS of two racing vehicles are profiled: the Dyson Lola LMP1 and Audi R18 e-tron Quattro. Four SAE technical papers follow the preface and focus on the use of KERS technology in F1 racing.

The transmissions sector is no longer primarily driven by cost control and installed capacity, but is emerging as a critical technology that can deliver much needed benefits in a cost-effective fashion compared to other areas of technology. Furthermore, transmission technology is also critical to future powertrain development in terms of its ability to deliver both drivability and emissions-reducing performance. The transmission essentially controls the driving experience that the customer enjoys and makes a significant contribution to the fuel consumption performance of the vehicle. Therefore, as OEMs strive to differentiate their product offering transmission choice and performance have become an essential element of the ‘DNA’ of the vehicle. The fifth edition of this popular report begins by examining transmission development drivers along with transmission development changes. The report goes on to examine transmissions technology, with particular attention to Manual Transmissions (MT), Dual Clutch Automated Manual Transmissions (DCT), Automatic Transmissions, Continuously Variable Transmissions (CVT), Hybrid Transmissions and Electric Vehicle Transmissions.

This compendium is an update to two best-selling editions published by SAE International in 1995 and 2003. Editor Doug Fehan has assembled a collection of technical papers from the SAE archive that will inspire readers to use race engine development as an important tool in the future of transportation. He focuses on several topics that are important to future race engine design: electrification, materials and processes, and improved technology. Today’s electric hybrid vehicles and kinetic energy recovery systems embody what inventors envisioned in the early 1900s. First employed in trams and trains of that era, the technology was almost forgotten until racers resurrected their version in 2009 F-1 racing. The automotive industry has long admired the aircraft industry’s use of lightweight metals, advanced finishing processes, and composites. The use of these materials and processes has helped reduce overall mass and, in turn, improved speed, performance, and reliability of race engines. Their initial high cost was a limiting factor for integrating them into mass-produced vehicles.

While the basic working principle and the mechanical construction of automatic transmissions has not changed significantly, increased requirements for performance, fuel economy, and drivability, as well as the increasing number of gears has made it more challenging to design the systems that control modern automatic transmissions. New types of transmissions—continuously variable transmissions (CVT), dual clutch transmissions (DCT), and hybrid powertrains—have presented added challenges. Gear shifting in today’s automatic transmissions is a dynamic process that involves synchronized torque transfer from one clutch to another, smooth engine speed change, engine torque management, and minimization of output torque disturbance. Dynamic analysis helps to understand gear shifting mechanics and supports creation of the best design for gear shift control systems in passenger cars, trucks, buses, and commercial vehicles. Based on the authors’ graduate-level teaching material, this well-illustrated book relays how the fundamental principles of hydraulics and control systems are applied to today’s automatic transmissions.

Hydrogen, energy vector for the future? Or, on the contrary, limited to its current applications in the field of chemistry and refining for decades to come, possibly even until the end of the century? There is much controversy over this issue and two sides to the argument. Advocates of the hydrogen civilization consider that, following a technological revolution hydrogen will play a universal role alongside electricity as a substitute for fossil fuels, especially (but not only) in transport, leading to radical elimination of CO2 emissions. For the skeptics, and even outspoken opponents, hydrogen will remain restricted to its current applications due to the insoluble problems inherent to its generalized use, especially in transport. This book highlights the increasing and inevitable role of "energy" hydrogen – as opposed to chemical hydrogen – in the key sectors of transport and "clean" electricity production. The first section is dedicated to current applications of energy hydrogen or those within reach in the not too distant future.

The increasing concern about CO2 emissions and energy prices has led to new CO2 emission and fuel economy legislation being introduced in world regions served by the automotive industry. In response, automotive manufacturers and Tier-1 suppliers are developing a new generation of internal combustion (IC) engines with ultra-low emissions and high fuel efficiency. To further this development, a better understanding is needed of the combustion and pollutant formation processes in IC engines. As efficiency and emission abatement processes have reached points of diminishing returns, there is more of a need to make measurements inside the combustion chamber, where the combustion and pollutant formation processes take place. However, there is currently no good overview of how to make these measurements. Based on the author’s previous SAE book, Engine Combustion Instrumentation and Diagnostics, this book focuses on laser-based optical techniques for combustion flows and in-cylinder measurements.

Engine failures result from a complex set of conditions, effects, and situations. To understand why engines fail and remedy those failures, one must understand how engine components are designed and manufactured, how they function, and how they interact with other engine components. To this end, this book examines how engine components are designed and how they function, along with their physical and technical properties. Translated from a popular German reference work, this English edition sheds light on determining engine failure and remedies. The authors present a selection of engine failures, investigate and evaluate why they failed, and provide guidance on how to prevent such failures. A large range of possible engine failures is presented in a comprehensive, readily understandable manner, free of manufacturer bias. The scope of engines covered includes general-purpose engines found in heavy commercial vehicles, railway locomotives and vehicles, electrical generators, prime movers, and marine engines.
