This book was released on 2015-09-28 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.
Download or read book Assessment of Fuel Economy Technologies for Light Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2011-06-03 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various combinations of commercially available technologies could greatly reduce fuel consumption in passenger cars, sport-utility vehicles, minivans, and other light-duty vehicles without compromising vehicle performance or safety. Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle. The book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel. Because fuel consumption data indicate money saved on fuel purchases and reductions in carbon dioxide emissions, the book finds that vehicle stickers should provide consumers with fuel consumption data in addition to fuel economy information.
Download or read book Knocking in Gasoline Engines written by Michael Günther and published by Springer. This book was released on 2017-11-21 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book includes the papers presented at the conference discussing approaches to prevent or reliably control knocking and other irregular combustion events. The majority of today’s highly efficient gasoline engines utilize downsizing. High mean pressures produce increased knocking, which frequently results in a reduction in the compression ratio at high specific powers. Beyond this, the phenomenon of pre-ignition has been linked to the rise in specific power in gasoline engines for many years. Charge-diluted concepts with high compression cause extreme knocking, potentially leading to catastrophic failure. The introduction of RDE legislation this year will further grow the requirements for combustion process development, as residual gas scavenging and enrichment to improve the knock limit will be legally restricted despite no relaxation of the need to reach the main center of heat release as early as possible. New solutions in thermodynamics and control engineering are urgently needed to further increase the efficiency of gasoline engines.

Download or read book Technologies and Approaches to Reducing the Fuel Consumption of Medium and Heavy Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2010-07-30 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

Download or read book Transitions to Alternative Vehicles and Fuels written by National Research Council and published by National Academies Press. This book was released on 2013-04-14 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a century, almost all light-duty vehicles (LDVs) have been powered by internal combustion engines operating on petroleum fuels. Energy security concerns about petroleum imports and the effect of greenhouse gas (GHG) emissions on global climate are driving interest in alternatives. Transitions to Alternative Vehicles and Fuels assesses the potential for reducing petroleum consumption and GHG emissions by 80 percent across the U.S. LDV fleet by 2050, relative to 2005. This report examines the current capability and estimated future performance and costs for each vehicle type and non-petroleum-based fuel technology as options that could significantly contribute to these goals. By analyzing scenarios that combine various fuel and vehicle pathways, the report also identifies barriers to implementation of these technologies and suggests policies to achieve the desired reductions. Several scenarios are promising, but strong, and effective policies such as research and development, subsidies, energy taxes, or regulations will be necessary to overcome barriers, such as cost and consumer choice.

Download or read book Concepts in Turbocharging for Improved Efficiency and Emissions Reduction written by Mehrdad Zangeneh and published by SAE International. This book was released on 2014-09-22 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legislative requirements to reduce CO2 emissions by 2020 have resulted in significant efforts by car manufacturers to explore various methods of pollution abatement. One of the most effective ways found so far is by shortening the cylinder stroke and downsizing the engine. This new engine then needs to be boosted, or turbocharged, to create the full and original load torque. Turbocharging has been and will continue to be a key component to the new technologies that will make a positive difference in the next-generation engines of years to come. Concepts in Turbocharging for Improved Efficiency and Emissions Reduction explores the many ways that turbocharging will deliver concrete results in meeting the new realities of sustainable, green transportation. This collection of very focused technical papers, selected by Mehrdad Zangeneh, PhD., a professor of thermo-fluids at University College in London, provides an assessment of several novel designs intended to improve fuel consumption and cap emissions, while maintaining torque at all speeds. The book is divided into four sections, each addressing the most cutting-edge technologies on the market today: o Two-Stage Turbocharging o Variable Geometry Compressors o Unconventional Compressor Configurations o Electrically Assisted Turbocharging
Download or read book Automotive Exhaust Emissions and Energy Recovery written by Apostolos Pesiridis and published by Nova Science Pub Incorporated. This book was released on 2014-01-01 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns for fuel economy and reduced emissions have turned the attention of automotive internal combustion engine manufacturers to the exhaust system and towards technological system development to account for the significant levels of potential energy that can be recovered. The present volume on Automotive Exhaust Emissions and Energy Recovery for both gasoline and diesel engines is therefore both timely and appropriate. Whereas diesel engines have been predominantly turbocharged, only a relatively small percentage of gasoline engines are similarly equipped, which has led to significant efforts by engine manufacturers in recent years to downsize and down-speed these engines. On the other hand, the relative focus in diesel engine development in terms of emissions and exhaust energy recovery has shifted toward devices other than the turbocharger for enhanced energy recovery and emissions control technologies in order to allow the diesel engines of the future to keep up with the dual-demand for very low emissions and increasing levels of fuel economy. The book focuses on the exhaust system and the technologies and methods used to reduce emissions and increase fuel economy by capitalising on the exhaust gas energy availability (either in the form of gas kinetic energy or as waste heat extracted from the exhaust gas). It is projected that in the short to medium term, advances in exhaust emissions and energy recovery technologies will lead the way in internal combustion engine development and pave the way towards increasing levels of engine hybridisation until fully electric vehicle technology can claim a level of maturity and corresponding market shares to turn the bulk of this focus away from the internal combustion engine. This book is aimed at engine research professionals in the industry and academia, but also towards students of powertrain engineering. The collection of articles in this book reviews the fundamentals of relevance, recent exhaust system technologies, details recent or on-going projects and uncovers future research directions and potentials.

Book excerpt: This book presents the papers from the latest international conference, following on from the highly successful previous conferences in this series held regularly since 1978. Papers cover all current and novel aspects of turbocharging systems design for boosting solutions for engine downsizing. The focus of the papers is on the application of turbocharger and other pressure charging devices to spark ignition (SI) and compression ignition (CI) engines in the passenger car and commercial vehicles. Novel boosting solutions for diesel engines operating in the industrial and marine market sectors are also included.The current emission legislations and environmental trends for reducing CO2 and fuel consumption are the major market forces in the transport (land and marine) and industry sectors. In these market sectors the internal combustion engine is the key product where downsizing is the driver for development for both SI and CI engines in the passenger car and commercial vehicle applications. The more stringent future market forces and environmental considerations mean more stringent engine downsizing, thus, novel systems are required to provide boosting solutions including hybrid, electric-motor and exhaust waste energy recovery systems for high efficiency, response, reliability, durability and compactness etc. For large engines the big challenge is to enhance the high specific power and efficiency whilst reducing emission levels (Nox and Sox) with variable quality fuels. This will require turbocharging systems for very high boost pressure, efficiency and a high degree of system flexibility. - Presents papers from all the latest international conference - Papers cover all aspects of the turbocharging systems design for boosting solutions for engine downsizing - The focus of the papers is on the application of turbocharger and other pressure charging devices to spark ignition (SI) and compression ignition (CI) engines in the passenger car and commercial vehicles
Download or read book Turbochargers and Turbocharging written by Evangelos G. Giakoumis and published by Nova Science Publishers. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercharging has long been established as the most successful means to maximise power output from a specific engine size. Through supercharging, the inlet air density is increased, usually by means of a compressor, and by doing so the amount of air trapped in the cylinders is increased accordingly. As a result, efficient burning of a proportionately higher amount of fuel is enabled. By far, the most successful version of supercharging is turbocharging. Here, the expansion in a turbine of the exhaust gases leaving the cylinders supplies the power needed to drive the compressor. At the moment, practically all diesel engines are turbocharged, with a continuously increasing penetration in the highly competitive market of SI-powered vehicles. The current book on turbochargers and turbocharging, comprising fifteen chapters, gathers important and novel research on many modern aspects of turbocharging for all kinds of gasoline and diesel-powered engine applications (automotive, truck, marine and aircraft). For example, characterisation of the value proposition of turbocharged vehicles, marine engines turbo-compounding, fundamental issues of turbocharger lag and its relation with engine-out PM emissions, variable geometric compressors, automotive two-stage turbocharging, and dynamic operation of turbochargers including VGT and surging effects are amongst the topics analysed. Review papers form a very important part of the book, namely the discussion and in-depth analysis of various automotive boosting systems, turbocharger reduced-order modeling, heat transfer and pulsating flows in turbomachinery, mathematical models for turbocharged engines, and turbomachine-based engine throttling. A considerable portion of the book (seven chapters) deals with control-oriented modeling techniques relating to the turbocharger and/or the whole engine power-plant. Such models have proven valuable during the design of both turbochargers and turbocharged engines, and are described and discussed in detail for a variety of automotive and aircraft applications. The book is written for post-graduate students, engineers and researchers in the field of internal combustion engines (diesel and SI) and turbochargers.
