This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The following research thesis focuses on methods of controlling nitrogen oxides (NO_x) and particulate matter (PM) emissions emitted from a low temperature diesel exhaust. This involves studying the influence of hydrogen (H2) on various aftertreatment devices such as hydrocarbon selective catalytic reduction (HC-SCR) over silver-alumina (Ag-Al2O3) catalysts for lean NO_x reduction, platinum diesel oxidation catalysts (DOC) for nitrogen dioxide (NO2) production and passive regeneration methods for the diesel particulate filter (DPF). H2 was implemented on-board either through diesel exhaust gas fuel reforming or via the simulation of ammonia (NH3) dissociation. Both methods showed to be very effective in enhancing the activity of a silver HC-SCR catalyst for the reduction of NO_x with conversions reaching 90% with the aid of an upstream DPF. A combined DOC and catalysed DPF (cDPF) configuration proved promising for passive regeneration in the presence of reformed exhaust gas recirculation (REGR). The addition of H2 over the DOC led to an improved catalyst light-off temperature and increased rate of oxidation for NO2 production. Implementing filtered EGR (FEGR) removes the hydrocarbon (HC) and soot recirculation penalty, thus minimising particulate growth which results in a significantly reduced engine-out soot emission during exhaust gas recirculation (EGR) and hence, an improved NO_x/soot ratio. Introducing fuel components which enhance the cetane number and oxygenate the diesel fuel allow better control of the NO_x/soot trade-off with improved soot oxidation properties.

Available in PDF, EPUB and Kindle. Book excerpt: The use of diesel-powered equipment in underground mining operations provides many benefits to the industry. It also presents many challenges to the health and safety of workers as it is a significant source of submicrometer aerosols and noxious gases. This book was developed to assist the coal and metal/nonmetal underground mining industries in their efforts to reduce the exposure of workers to aerosols and gases from diesel-powered equipment. It includes information collected by researchers at the National Institute for Occupational Safety and Health/Office of Mine Safety and Health Research (NIOSH/OMSHR). Prior to the production of this text, the knowledge on this complex issue was fragmented. The goal of this volume is to make the information available in one easy-to-use reference. The book includes comprehensive, mine-specific programs for use by mechanics, mine ventilation engineers, industrial hygienists, mine managers, union health and safety representatives, and personnel responsible for the acquisition of diesel vehicles, engines, exhaust aftertreatment systems, fuels, and lubricants. The description of methods to reduce exposure to diesel aerosols includes curtailment of diesel particulate matter and gaseous emissions at their source, and controlling airborne pollutants with ventilation and personal protective equipment. This information should also help researchers in industry, government, and academia to identify areas that need to be addressed in future research and development efforts.

Download or read book Membrane-Based Air Composition Control for Light-Duty Diesel Vehicles: A Benefit and Cost Assessment written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the methodologies and results of a study conducted by Argonne National Laboratory (Argonne) to assess the benefits and costs of several membrane-based technologies. The technologies evaluated will be used in automotive emissions-control and performance-enhancement systems incorporated into light-duty diesel vehicle engines. Such engines are among the technologies that are being considered to power vehicles developed under the government-industry Partnership for a New Generation of Vehicles (PNGV). Emissions of nitrogen oxides (NO[sub x]) from diesel engines have long been considered a barrier to use of diesels in urban areas. Recently, particulate matter (PM) emissions have also become an area of increased concern because of new regulations regarding emissions of particulate matter measuring 2.5 micrometers or less (PM[sub 2.5]). Particulates are of special concern for diesel engines in the PNGV program; the program has a research goal of 0.01 gram per mile (g/mi) of particulate matter emissions under the Federal Test Procedure (FTP) cycle. This extremely low level (one-fourth the level of the Tier II standard) could threaten the viability of using diesel engines as stand-alone powerplants or in hybrid-electric vehicles. The techniques analyzed in this study can reduce NO[sub x] and particulate emissions and even increase the power density of the diesel engines used in light-duty diesel vehicles.

Download or read book Report to Congress written by U. S. Environmental Agency and published by CreateSpace. This book was released on 2015-01-06 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing emissions from diesel engines is one of the most important public health challenges facing the country. Despite EPA's stringent diesel engine and fuel standards taking effect over the next decade, the 20 million engines already in use will continue to emit large amounts of nitrogen oxides (NOX) and particulate matter (PM)-both of which will contribute to serious public health problems for years to come. Fortunately, a variety of cost-effective technologies can dramatically reduce harmful emissions, save fuel, and help our nation meet its clean air and sustainability goals. To meet these challenges, the U.S. Environmental Protection Agency (EPA) established the National Clean Diesel Campaign (NCDC). NCDC consists of both regulatory programs to address new engines and innovative nonregulatory programs to address the millions of diesel engines already in use. EPA standards apply to new diesel engines, and because these engines can last a long time, solutions are needed to reduce harmful emissions from the existing fleet. These innovative approaches promote a variety of emission reduction strategies such as retrofitting, repairing, replacing, and repowering engines; reducing idling; and switching to cleaner fuels. Through a dynamic network of Regional Collaboratives, whose development EPA initiated, environmental groups, industry, and government were inspired and motivated-despite their sometimes conflicting perspectives-to unite behind a common goal. NCDC mobilized diverse and unusual partners with historic differences to work together, creating broad support based on the urgency of the public health problem and bringing new technologies into use years earlier than would otherwise have occurred.

Book Synopsis Lowering USAF Diesel Engine NOx Emissions With Utilizing B20 Biodiesel Fuel by :
Download or read book Lowering USAF Diesel Engine NOx Emissions With Utilizing B20 Biodiesel Fuel written by and published by . This book was released on 2005 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Air Force can utilize B20 biodiesel fuel to partially meet EPAct requirements for alternative fuel use, and to lower criteria pollutants except for NOx. Relatively minor production component changes, and selected minor operating condition changes can alter engine out NOx emissions with biodiesel fuels in a 6.5L HMMWV engine. For a nonroad ISO 8178 test cycle, weighted average Smoke/PM emissions can be similar to DF-2 levels at the condition that gives equivalent NOx emissions with B20 biodiesel fuel. In other words, Smoke/PM emissions with B20 biodiesel can be traded-off for improved NOx emissions. For the 6.5L HMMWV engine tested the composite control strategy did not severely impact emissions or fuel consumption when the engine operated on JP-8 fuel.

Book Synopsis Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles by : National Research Council
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.
