This book was released on 2003 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenge for truck engine product engineering is not only to fulfill increasingly stringent emission requirements, but also to improve the engine's economical viability in its role as the backbone of our global economy. While societal impact and therefore emission limit values are to be reduced in big steps, continuous improvement is not enough but technological quantum leaps are necessary. The introduction and refinement of electronic control of all major engine systems has already been a quantum leap forward. Maximizing the benefits of these technologies to customers and society requires full use of parameter optimization and other enabling technologies. The next big step forward will be widespread use of exhaust aftertreatment on all transportation related diesel engines. While exhaust gas aftertreatment has been successfully established on gasoline (Otto cycle) engines, the introduction of exhaust aftertreatment especially for heavy-duty diesel engines will be much mo re demanding. Implementing exhaust gas aftertreatment into commercial vehicle applications is a challenging task but the emission requirements to be met starting in Europe, the USA and Japan in the 2005-2007 timeframe require this step. The engine industry will be able to implement the new technology if all stakeholders support the necessary decisions. One decision has already been taken: the reduction of sulfur in diesel fuel being comparable with the elimination of lead in gasoline as a prerequisite for the three-way catalyst. Now we have the chance to optimize ecology and economy of the Diesel engine simultaneously by taking the decision to provide an additional infrastructure for a NOx reduction agent needed for the introduction of the Selective Catalytic Reduction (SCR) technology that is already implemented in the electric power generation industry. This requires some effort, but the resulting societal benefits, fuel economy and vehicle life cycle costs are significantly better when compared to other competitive technologies. After long discussions this decision for SCR has been made in Europe and is supported by all truck and engine manufacturers. The necessary logistic support will be in place when it will be needed commercially in 2005. For the US the decision has to be taken this year in order to have the infrastructure available in 2007. It will enable the global engine industry to focus their R & D resources in one direction not only for 2007, but for the years beyond 2010 with the best benefit for the environment, the customers and the industry.

This book was released on 2008-10-19 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21st Century Truck Partnership (21CTP), a cooperative research and development partnership formed by four federal agencies with 15 industrial partners, was launched in the year 2000 with high hopes that it would dramatically advance the technologies used in trucks and buses, yielding a cleaner, safer, more efficient generation of vehicles. Review of the 21st Century Truck Partnership critically examines and comments on the overall adequacy and balance of the 21CTP. The book reviews how well the program has accomplished its goals, evaluates progress in the program, and makes recommendations to improve the likelihood of the Partnership meeting its goals. Key recommendations of the book include that the 21CTP should be continued, but the future program should be revised and better balanced. A clearer goal setting strategy should be developed, and the goals should be clearly stated in measurable engineering terms and reviewed periodically so as to be based on the available funds.

Download or read book Engines and Fuels for Future Transport written by Gautam Kalghatgi and published by Springer Nature. This book was released on 2021-12-13 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on clean transport and mobility essential to the modern world. It discusses internal combustion engines (ICEs) and alternatives like battery electric vehicles (BEVs) which are growing fast. Alternatives to ICEs start from a very low base and face formidable environmental, material availability, and economic challenges to unlimited and rapid growth. Hence ICEs will continue to be the main power source for transport for decades to come and have to be continuously improved to improve transport sustainability. The book highlights the need to assess proposed changes in the existing transport system on a life cycle basis. The volume includes chapters discussing the challenges faced by ICEs as well as chapters on novel fuels and fuel/ engine interactions which help in this quest to improve the efficiency of ICE and reduce exhaust pollutants. This book will be of interest to those in academia and industry alike.

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.

Available in PDF, EPUB and Kindle. Book excerpt: TRB Special Report 227 - New Trucks for Greater Productivity and Less Road Wear: An Evaluation of the Turner Proposal evaluates the approach to regulation of the size and weight of trucks using U.S. roads known as the Turner Proposal. This approach had its origin in a proposal put forth in a 1984 address to AASHTO by former Federal Highway Administrator Francis C. Turner. The approach evaluated by the committee differs in an important respect from Turner's original concept: in the committee's approach, use of the new trucks would be voluntary; that is, truck operators would be offered the choice of continuing with existing equipment and weight rules or adopting the new trucks with the new weight regulations. The committee designed a package of changes in size and weight limits, safety restrictions, and procedures regarding bridge deficiencies, routing, and enforcement that would be a practical regulatory scheme for implementing the Turner concept. The committee recommends that every state, with careful assessment of the risks and uncertainties, consider this proposal as a supplement to current size and weight regulations. If Turner trucks were adopted in all states according to the recommended rules, they would reduce the cost of shipping freight and would not degrade safety. The total cost of maintaining the road system would be reduced, although pavement wear savings would be partially offset by higher bridge costs. The committee that carried out this study identified two truck configurations outside the weight and length limits established by federal law that would offer greater productivity without increasing infrastructure or safety costs. These vehicles formed the basis for the configurations recommended in a later (2002) TRB report, Special Report 267: Regulation of Weights, lengths, and Widths of Commercial Motor Vehicles.

Book excerpt: As a diesel, liberty, and self-reliance enthusiast, Mark A. Billy wanted the family and load hauling capabilities of a full sized truck without the horrible fuel economy or the excessive price. As an engineer, he understood the efficiency and torque that turbodiesel engines provide. He knew that his goals were achievable if the right decisions were made. So, he decided to build a practical hauler for his family that wouldn't break the bank. He started with an unusual host for an efficiency project: a large, heavy, brick-shaped 1999 Suburban. He integrated a 3.9 liter Isuzu turbodiesel engine and a five-speed manual transmission into this vehicle, creating a cavernous family conveyance that cruises at highway speeds while achieving 26 mpg. The Suburban retains functional four wheel drive, cruise control, and air conditioning. Because a mechanically-injected engine and a manual transmission were used, the drivetrain of the vehicle is EMP-proof. With a 40 gallon fuel tank, the vehicle can achieve a range of over 1000 miles without refueling. This book describes the author's decision-making process as he chose, modified, and installed the components in his conversion process. He shares a number of lessons he learned the hard way, in the hopes that sharing his experience will make it easier for others to pursue similar projects.

This book was released on 2005 with total page 1709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cummins Inc., in partnership with the Department of Energy, has developed technology for a new highly efficient, very low emission, diesel engine for light trucks and sport utility vehicles. This work began in April 1997, and started with very aggressive goals for vehicles in the 5751 to 8500 pound GCW weight class. The primary program goals were as follows: (1) EMISSIONS -- NOx = 0.50 g/mi; PM = 0.05 g/mi; CO = 2.8 g/mi; and NMHC = 0.07 g/mi. California decided to issue new and even tougher LEV II light truck regulations late in 1999. EPA also issued its lower Tier 2 regulations late in 2000. The net result was that the targets for this diesel engine project were lowered, and these goals were eventually modified by the publication of Federal Tier 2 emission standards early in 2000 to the following: NOx = 0.07 g/mi; and PM = 0.01 g/mi. (2) FUEL ECONOMY -- The fuel economy goal was 50 percent MPG improvement (combined city/highway) over the 1997 gasoline powered light truck or sport utility vehicle in the vehicle class for which this diesel engine is being designed to replace. The goal for fuel economy remained at 50 percent MPG improvement, even with the emissions goal revisions. (3) COOPERATIVE DEVELOPMENT -- Regular design reviews of the engine program will be conducted with a vehicle manufacturer to insure that the concepts and design specifics are commercially feasible. (DaimlerChrysler has provided Cummins with this design review input.) Cummins has essentially completed a demonstration of proof-of-principle for a diesel engine platform using advanced combustion and fuel system technologies. Cummins reported very early progress in this project, evidence that new diesel engine technology had been developed that demonstrated the feasibility of the above emissions goals. Emissions levels of NOx = 0.4 g/mi and PM = 0.06 g/mi were demonstrated for a 5250 lb. test weight vehicle with passive aftertreatment only. These results were achieved using the full chassis dynamometer FTP-75 test procedure that allowed compliance with the Tier 2 Interim Bin 10 Standards and would apply to vehicles in MY2004 through MY2007 timeframe. In further technology development with active aftertreatment management, Cummins has been able to report that the emissions goals for the Tier 2 Bin 5 standards were met on an engine running the full FTP-75 test procedure. The fuel economy on the chassis tests was measured at over 59 percent MPG improvement over the gasoline engines that are offered in typical SUVs and light trucks. The above demonstration used only in-cylinder fueling for management of the aftertreatment system.
