Download or read book On Road and In Laboratory Testing to Demonstrate Effects of ULSD B20 and B99 on a Retrofit Urea SCR Aftertreatment System written by and published by . This book was released on 2010 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions changes for a 2005 International tractor operating on low-sulfur diesel and biodiesel in Santa Monica were measured to demonstrate performance and impacts of selective catalytic reduction. Results from this testing showed that oxides of nitrogen (NOx) emissions increased by 6% - 12% when the blend was increased from ULSD to B20, by 16% - 35% when the blend was increased from ULSD to B99, and by 26% - 27% when it was increased from B20 to B99. Particulate matter (PM) emissions decreased by 37% - 50% when the blend was increased from ULSD to B20, by 71% - 79% when it was increased from ULSD to B99, and by 60% - 63% when it was increased from B20 to B99. The SCR system reduced NOx emissions by 64%- 87%, and its performance was not affected by the use of biodiesel.

Download or read book Vehicle Fuel Economy written by United States Government Accountability Office and published by Createspace Independent Publishing Platform. This book was released on 2017-09-15 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over national security, environmental stresses, and high fuel prices have raised interest in reducing oil consumption. Through the Corporate Average Fuel Economy (CAFE) program, the National Highway Traffic Safety Administration (NHTSA) requires cars and light trucks to meet certain fuel economy standards. As requested, GAO discusses (1) how CAFE standards are designed to reduce fuel consumption, (2) strengths and weaknesses of the CAFE program and NHTSA's capabilities, and (3) market-based policies that could complement or replace CAFE. To do this work, GAO reviewed recent studies and interviewed leading experts and agency officials.
Download or read book Highway and Urban Environment written by G.M. Morrison and published by Springer Science & Business Media. This book was released on 2007-09-19 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: With half of the world’s population now living in urban areas, and rapid urbanization continuing apace, it is essential that the growth of urban areas is supported by the development of adequate and sustainable infrastructure. This work offers comprehensive coverage of critical issues on the highway and urban environment which are key to understanding sustainability in the world's expanding urban areas.

Available in PDF, EPUB and Kindle. Book excerpt: The 9th Highway and Urban Environment Symposium (9HUES) was held in Madrid, Spain, from 9-11 June 2008. HUES is run by Chalmers University of Technology within the Alliance for Global Sustainability (The AGS). HUES was initiated by Professor Ron Hamilton at Middlesex Polytechnic (now University) in the early 1980s and had the title "Highway Pollution". The initial aim was to measure and assess challenges in highway pollution, with a strong emphasis on urban photochemical smog, ozone formation and particle release. After the first symposium, the emphasis on air pollution issues continued through to Munich in 1989 where diesel particulate issues and the relevance to health through measurements of PM10 emerged. The focus on air quality issues was also strengthened. In parallel, the symposium started to receive an increasing number of scientific contributions from the area of urban run off, indeed to the extent that the title of the symposium was changed to "Highway and Urban Pollution". Since then the importance of science in support of policy became increasingly important as a key aspect of the symposium. 9HUES was held at TRANSyT- Universidad Politécnica de Madrid, Spain to provide a professional and scientific forum on global examples of the science required to support pathways to a positive and sustainable future in the highway and urban environment.
