Book Description
Contributions by Surhid Gautam and Lit-Mian Chan. This book presents a state-of-the art review of vehicle emission standards and regulations and provides a synthesis of worldwide experience with vehicle emission control technologies and their applications in both industrial and developing countries. Topics covered include: * The two principal international systems of vehicle emission standards: those of North America and Europe * Test procedures used to verify compliance with emissions standards and to estimate actual emissions * Engine and aftertreatment technologies that have been developed to enable new vehicles to comply with emission standards, as well as the cost and other impacts of these technologies * An evaluation of measures for controlling emissions from in-use vehicles * The role of fuels in reducing vehicle emissions, the benefits that could be gained by reformulating conventional gasoline and diesel fuels, the potential benefits of alternative cleaner fuels, and the prospects for using hydrogen and electric power to run motor vehicles with ultra-low or zero emissions. This book is the first in a series of publications on vehicle-related pollution and control measures prepared by the World Bank in collaboration with the United Nations Environment Programme to underpin the Bank's overall objective of promoting transport that is environmentally sustainable and least damaging to human health and welfare.

ISBN: 3319159283
Category : Science
Languages : en
Pages : 146
Book Description
This book focuses on particulate matter emissions produced by vehicles with combustion engines. It describes the physicochemical properties of the particulate matter, the mechanisms of its formation and its environmental impacts (including those on human beings). It discusses methods for measuring particulate mass and number, including the state-of-the-art in Portable Emission Measurement System (PEMS) equipment for measuring the exhaust emissions of both light and heavy-duty vehicles and buses under actual operating conditions. The book presents the authors’ latest investigations into the relations between particulate emission (mass and number) and engine operating parameters, as well as their new findings obtained through road tests performed on various types of vehicles, including those using diesel particulate filter regeneration. The book, which addresses the needs of academics and professionals alike, also discusses relevant European regulations on particulate emissions and highlights selected methods aimed at the reduction of particulate emissions from automobiles.

New Trends in Emission Control in the European Union

ISBN: 3319027050
Category : Technology & Engineering
Languages : en
Pages : 175
Book Description
This book discusses recent changes in the European legislation for exhaust emissions from motor vehicles. It starts with a comprehensive explanation of both the structure and range of applicability of new regulations, such as Euro 5 and Euro 6 for light-duty vehicles and Euro VI for heavy-duty vehicles. Then it introduces the most important issues in in-service conformity and conformity of production for vehicles, describing the latest procedures for performing exhaust emissions tests under both bench and operating conditions. Subsequently, it reports on portable emission measurement systems (PEMS) and their application for assessing the emissions of gaseous and particulate matter alike, under actual operating conditions and in all transport modes. Lastly, the book presents selected findings from exhaust emissions research on engines for a variety of transport vehicles, such as light-duty and heavy-duty vehicles, as well as non-road vehicles, which include farm tractors, groundwork and forest machinery, diesel locomotives, high-rail vehicles, combat vehicles and special-purpose vehicles. This work offers a valuable reference guide for researchers and professionals dealing with environmental regulations and vehicle manufacturing in the European Union.

Book Description
The purpose of this study is to investigate the effect of filter face temperature on the measured primary particulate matter (PM) from light-duty gasoline vehicles (LDGVs). In 2009, seventeen in-use LDGVs with model years of 2001 through 2009 and odometer readings of 12,000 to 502,000 miles were tested on a chassis dynamometer following the Federal Test Procedure (FTP) specified in the Code of Federal Regulation (CFR) for emissions sampling and measurement. During the testing, summer-time and winter-time California phase 3 reformulated gasoline (CaRFG) were used in the test vehicles. The FTP test cycle included a cold-start test and a hot-start test; gaseous and particulate mass emissions were collected by sampling bags and filters, respectively, at the transient phase of the cold-start test, stabilized phase of the cold-start test and transient phase of the hot-start test. Tailpipe particulate emissions were collected on Teflon filters, which were maintained at the CFR-specified standard temperature for FTP test cycle (i.e. CFR temperature) of 47±5°C, and alternatively, at an ambient cell temperature of 22±5°C (i.e. cell temperature). The average particulate mass and gaseous emission rates of the test vehicles were then determined according to the CFR-specified calculation procedures. The average particulate mass emission rate at the CFR and cell filter face temperature were 1.3±0.3 and 1.9±0.4 mg/mi, respectively. The average gaseous emission rate of hydrocarbon (HC), carbon monoxide (CO), and nitrogen oxides (NOx) for the tested LDGVs were 0.08 mg/mi, 1.47 mg/mi, and 0.13 mg/mi, respectively. Statistical hypothesis testing methods, such as the sign test, were used to establish whether there is an association between filter face temperature and measured particulate mass emission from the test vehicles. Based on the test data, the result of the hypotheses testing indicates that the particulate mass emissions sampled at a lower filter face temperature (i.e. cell temperature) were not significantly greater than those sampled at a higher filter face temperature (i.e. CFR temperature), at a 0.05 level of significance.
