Download or read book Air Pollution from Motor Vehicles written by Asif Faiz and published by World Bank Publications. This book was released on 1996-01-01 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1966 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of automobile exhaust as a source of atmospheric pollutants has been recognized for several years. With the control of stationary sources in geographic areas such as Los Angeles County, the automobile has become the major uncontrolled source of air pollution. The three major pollutants emitted by automobiles are unburned hydrocarbons, carbon monoxide, and oxides of nitrogen. Seventy percent of the emissions are from the exhaust. Maximum emission standards of 275 ppm hydrocarbons as n-hexane and 1.5 mole percent carbon monoxide in automotive exhaust have been enacted in California. Control measures for the oxides of nitrogen may possibly be effective for 1970 model vehicles. Exhaust control devices for hydrocarbon and carbon monoxide emissions submitted to the California Motor Vehicle Pollution Control Board for approval have included catalytic converters, direct-flame afterburners, engine modification systems, and secondary air injection at the exhaust port systems. Three of the automobile manufactures may use the fourth system which involves introduction of secondary air into the engine exhaust ports to promote flameless oxidation of hydrocarbons and carbon monoxide to carbon dioxide and water. Since this control system introduces air to the high temperature exhaust gases at the exhaust port, the question arises whether oxides of nitrogen might be formed. This would be detrimental from the outlook that oxides of nitrogen must be controlled. The purpose of this work was to determine the effects on the emissions of oxides of nitrogen from a gasoline engine by the installation and operation of an exhaust port secondary air injection system. The engine under test, given to Oregon State University by the Ford Motor Company, was installed in a vehicle and operated on a chassis dynamometer. Measurements of oxides of nitrogen emissions with and without the air injection system in operation were made both during steady state and transient conditions. For transient measurements, the vehicle was operated on the California seven-mode test cycle. Oxides of nitrogen samples were taken by a progressive grab sampling technique and analyzed with an absorption spectrophotom eter built at Oregon State University. Further measurements included unburned hydrocarbon, carbon monoxide, and carbon dioxide analyses with commercial non-dispersive infrared analyzers and total carbon measurement with a commercial hydrogen flame ionization analyzer. These analyses were made for the purpose of determining air dilution factors and correlating data with other work being done in the field. The results of the investigation are summarized as follows: 1) The addition of secondary air at the exhaust ports in creased the oxides of nitrogen emissions during acceleration for both rich and lean mixture operation. As high as 40 percent in crease occurred during operation with the rich carburetor. Appreciable increase also occurred during high speed steady state cruise conditions with the rich carburetor. Weighted average concentrations of NO[subscript x] for operation on the California cycle were not determined. 2) The grab sampling and spectrophotometric analysis methods for the oxides of nitrogen worked well during the testing. However, the time required to take a grab sample, three seconds, was too long to obtain instantaneous analysis. Sampling probes should be located closer to the engine to avoid mixing of exhaust from separate modes in the exhaust pipe prior to analysis. 3) Temperatures in the exhaust manifold were not markedly changed by the injection of secondary air into the exhaust ports. However, temperatures were 50 to 100° F higher at the end of the tailpipe due to increased exhaust mass flow rate. 4) The vehicle with the air system installed met California standards for operation with the rich carburetor, but emitted a higher concentration of unburned hydrocarbons than the standard during operation with the lean carburetor.

Download or read book Automotive Emissions Regulations and Exhaust Aftertreatment Systems written by John Kasab and published by SAE International. This book was released on 2020-08-31 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to present a fundamental development of the science and engineering underlying the design of exhaust aftertreatment systems for automotive internal combustion engines. No pre-requisite knowledge of the field is required: our objective is to acquaint the reader, whom we expect to be new to the field of emissions control, with the underlying principles, control methods, common problems, and fuel effects on catalytic exhaust aftertreatment devices. We do this in hope that they can better understand the previous and current generations of emissions control, and improve upon them. This book is designed for the engineer, researcher, designer, student, or any combination of those, who is concerned with the control of automotive exhaust emissions. It includes discussion of theory and fundamentals applicable to hardware development.
