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.
Book Synopsis Modeling Health Effects of Particulate Matter Emissions from Heavy Duty Diesel Trucks Involved in High Volume Hydraulic Fracturing with BenMAP-CE by : Katelijn Van Munster
Download or read book Modeling Health Effects of Particulate Matter Emissions from Heavy Duty Diesel Trucks Involved in High Volume Hydraulic Fracturing with BenMAP-CE written by Katelijn Van Munster and published by . This book was released on 2018 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The use of high volume hydraulic fracturing (HVHF) has grown substantially in the past decade, and with it the number of heavy duty diesel trucks (HDDTs) used to transport HVHF materials and wastes. This research is a pilot study for the third phase of a three-phase project to determine the potential negative health effects caused by these HDDTs. This pilot study developed the methodology of modeling health effects, subsequent costs, and their spatial distribution with the Environmental Protection Agency’s Environmental Benefits Mapping and Analysis Program – Community Edition (BenMAP-CE), using data from previous phases of the project and focusing on the effects of fine particulate matter (PM2.5) emissions in and around Pittsburgh, PA. Health endpoints modeled include adult mortality, infant mortality, respiratory hospital admissions, and cardiovascular hospital admissions. Other emissions datasets modeled for comparison are: the Pennsylvania HDDT fleet of 2008, the Pennsylvania HDDT fleet upgraded to model year 2007 emissions regulations, and ambient PM2.5 pollution. PM2.5 emissions from HVHF HDDTs have a low impact compared to the other emissions datasets and caused less than 1 incidence for each health endpoint per 1 million people in the respective age groups. These findings are likely suppressed due to data estimation and averaging in this and previous phases. However, the HVHF HDDTs impact different communities than typical HDDT traffic due to different routes and the more rural nature of HVHF activity. This model also showed that emissions regulations can have a large positive impact on reducing health impacts. This thesis successfully developed methodology involving BenMAP-CE as a modeling tool, which can be used in future studies to help quantify the health impacts of emissions from HVHF-related activity."--Abstract.

Book Synopsis Modeling and Analysis of Particulate Matter Deposition and Regeneration in a Diesel Particulate Filter by : Mengting Yu
Download or read book Modeling and Analysis of Particulate Matter Deposition and Regeneration in a Diesel Particulate Filter written by Mengting Yu and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engines are widely used because of their high efficiency and low “greenhouse gas” emission. The particulate matter (PM) emitted by a diesel engine is collected and then burned in a diesel particulate filter (DPF). Analysis and modeling works have been done in this research to provide insight on optimization of the DPF design and operating conditions to achieve low pressure drop across the filter to decrease fuel consumption and low peak temperature during regeneration to avoid filter melting, cracking, and/or catalyst deactivation. Limiting models of the 1-D two-channel DPF model are analyzed. Analytical predictions and physical insight on the filtration velocity, pressure drop, heat transfer, light-off and regeneration in a DPF are obtained. The hydraulic analysis enables an efficient optimization of the DPF that lead to a more uniform PM deposition profile and a decrease of the pressure drop. The heat transfer, light-off and regeneration analysis enable estimations of the DPF heat-up time, the speed and width of the temperature front, the light-off temperature and time, and the peak regeneration temperature. New DPF regeneration procedures are proposed to limit the maximum local temperature rise. In various cases a DPF is connected by a wide-angled cone (diffuser) to the engine exhaust pipe. A 2-D axisymmetric PM deposition and regeneration model is developed to investigate the impact of the inlet cone on the deposition rate and the regeneration temperature as well as on the transient inlet velocity distribution among the various DPF channels. The highest regeneration temperature and thermal stress when using an inlet cone may be quite higher than when it is absent. A major technological challenge in the regeneration of the ceramic cordierite filter is that a sudden decrease of the engine load, referred to as Drop to Idle (DTI), may create a transient temperature peak much higher than under either the initial or final stationary feed conditions. This excessive transient temperature rise may cause local melting or cracking of the ceramic filter. Suggestions on how to limit the peak temperature rise following a DTI are provided through numerous simulations of the 1-D and 2-D DPF regeneration models.

Book Synopsis Hidden Costs of Energy by : National Research Council
Download or read book Hidden Costs of Energy written by National Research Council and published by National Academies Press. This book was released on 2010-05-26 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the many benefits of energy, most of which are reflected in energy market prices, the production, distribution, and use of energy causes negative effects. Many of these negative effects are not reflected in energy market prices. When market failures like this occur, there may be a case for government interventions in the form of regulations, taxes, fees, tradable permits, or other instruments that will motivate recognition of these external or hidden costs. The Hidden Costs of Energy defines and evaluates key external costs and benefits that are associated with the production, distribution, and use of energy, but are not reflected in market prices. The damage estimates presented are substantial and reflect damages from air pollution associated with electricity generation, motor vehicle transportation, and heat generation. The book also considers other effects not quantified in dollar amounts, such as damages from climate change, effects of some air pollutants such as mercury, and risks to national security. While not a comprehensive guide to policy, this analysis indicates that major initiatives to further reduce other emissions, improve energy efficiency, or shift to a cleaner electricity generating mix could substantially reduce the damages of external effects. A first step in minimizing the adverse consequences of new energy technologies is to better understand these external effects and damages. The Hidden Costs of Energy will therefore be a vital informational tool for government policy makers, scientists, and economists in even the earliest stages of research and development on energy technologies.
