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.

Book excerpt: The photos in this edition are black and white. Dyno Testing and Tuning is the first book to explain the proper testing procedures that everyone should use to get accurate and useful results from either an engine or chassis dyno. Authors Harold Bettes and Bill Hancock, recognized experts in the performance and racing industry, apply their wealth of knowledge and experience to deliver the definitive work on dynamometers and dyno testing. This book will be useful to anyone who wants to squeeze more power out of their car or engine, but should also be required reading for performance shop owners and dyno operators. The book explains how a dyno works, describes what kinds of data a dyno test can produce, and then shows you how to plan a test session that will give you the results you're looking for. You'll learn what to look for in a dyno facility, how to conduct a dyno test and ensure the accuracy and repeatability of your test, and how to troubleshoot any problems that arise. Sample forms and checklists round out what is sure to be an indispensable book for anyone who wants to make the most of their dyno testing.

Book excerpt: Currently Pennsylvania State University is only one of two academic institutions in the United States to have a certified heavy engine emissions test stand co-located with a heavy-duty vehicle chassis dynamometer. The goals of this thesis build upon this unique capability. First an engine stand is being built to allow the chassis dynamometer to also function as an engine dynamometer for heavy duty vehicles. This benefits not only university research, but also assists industry sponsors interested in testing their engines for performance, fuel economy, particulate formation, and chemical emissions. Through the use of telemetry, this project deploys the capability to capture data from a live vehicle on Penn State's test track and simultaneously load that data on to the engine on the tow-away chassis dynamometer being tested to simulate realistic driving conditions. This also provides more realistic testing situations, as typical engine dynamometer fuel economy tests run pre-programmed cycles on the engine to match federally mandated testing and thus miss effects of congestion, traffic light timing, weather-related driving changes, etc. Finally, the system was designed to be towed to remote sites, which enables easy use by student clubs, industry research, or even as demonstrations for classrooms.
Download or read book Interlaboratory Correlation of Chassis Dynamometer Test Results written by R. R. M. Johnston and published by . This book was released on 1985 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The testing of passenger car fuel consumption and exhaust emissions is carried out on chassis dynamometers of various makes and specifications. Correlation of results from difference installations may be carried out at regular intervals using a specially prepared vehicle containing a stable engine (for exhaust emissions), torque transducers, a fuel flow meter and an electronic data acquisition system. However, basic problems, such as establishing a consistent relationship between wheel speed of the test vehicle and the surface speed of the idler roller have received little attention. The present paper discusses these and other problems encountered in an interlaboratory correlation round involving more than 100 drive cycle tests in nine different chassis dynamometer laboratories throughout Australia. A method is presented of setting the tyre rolling circumference of the instrumented test car, which largely eliminates the wheel speed anomaly. In addition, a data analysis procedure, which separates absorbed power into components of friction, drag and inertia, has been used for diagnosing dynamometer and fuel consumption differences.
