Book excerpt: What is the purpose of idling? The scale of idling can be small, as when parents idle their vehicles while waiting for their children outside of school, or it can be large, as when ocean liners are in port. In many cases, the primary purpose for idling is to control the temperature of a passenger or freight compartment. Large line-haul trucks idle overnight to keep fuel and the engine warm, for the resting driver's comfort, to mask out noises and smells, and for safety. In addition, all classes of trucks idle during the workday at ports and terminals, busy delivery sites, border crossings, and other work sites. They may be idling to enable slow movement in a queue (creep idling) or to provide other services. Bus drivers also idle their vehicles while they wait for passengers and to warm up in the morning. Even locomotive engines are idled so they start, for hotel load, to keep the battery charged, to keep the toilet water from freezing, and for air brakes, or because the operator idles out of habit. Although this document focuses on long-haul trucks, much of the information applies to other vehicles as well. The impacts of idling are substantial, with as much as 6 billion gallons of fuel burned unnecessarily each year in the United States at a cost of over $20 billion. The extra hours of engine operation also cost the owners money for more frequent maintenance and overhauls. In addition, idling vehicles emit particulates (PM10), nitrogen dioxide (NO2), carbon monoxide (CO), and carbon dioxide (CO2). These emissions, along with noise from idling vehicles, have led to many local and state restrictions on idling. Two main factors have combined to create a surge of interest in idling reduction (IR): (1) Increasing restrictions on idling for heavy vehicles and (2) The price of diesel fuel. Because stakeholders focus their efforts on improving different factors (air quality, fuel economy, noise level), they do not necessarily agree on the most advantageous technological alternatives to implement. In addition, although many equipment manufacturers have tried to educate customers and government agencies, they often provide conflicting claims about the comparative merits of different devices. This makes it difficult for truck owners to choose the right equipment for their needs. In this study, we present the first comparison of IR technologies with each other and with idling on the basis of both costs and full fuel-cycle emissions, for different locations, fuel prices, and idling patterns. The preferences described are for the technologies that reduce total emissions the most and cost truck owners the least. We also discuss how regulatory issues and legislation affect IR, what financial incentives help to promote IR, and how outreach and education approaches can be adopted to reduce the need to idle. Finally, we offer a prediction of how future research and development (R & D), regulations, and citizen involvement can help to improve fuel economy and clean the air.

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.
Download or read book Emission Control and Fuel Economy written by John H Johnson and published by SAE International. This book was released on 2005-06-27 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emission and fuel economy regulations and standards are compelling manufacturers to build ultra-low emission vehicles. As a result, engineers must develop spark-ignition engines with integrated emission control systems that use reformulated low-sulfur fuel. Emission Control and Fuel Economy for Port and Direct Injected SI Engines is a collection of SAE technical papers that covers the fundamentals of gasoline direct injection (DI) engine emissions and fuel economy, design variable effects on HC emissions, and advanced emission control technology and modeling approaches. All papers contained in this book were selected by an accomplished expert as the best in the field; reprinted in their entirety, they present a pathway to integrated emission control systems that meet 2004-2009 EPA standards for light-duty vehicles.

Download or read book Making Cars More Fuel Efficient written by European Conference of Ministers of Transport and published by ECMT/OECD. This book was released on 2005 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies show that cars use significantly more fuel per km than suggested by official certification test ratings, and some argue that this gap is growing as a percentage of the tested value. This has raised concerns that national fuel efficiency and carbon dioxide emissions reduction goals will not be met, and that consumers will lose faith in reported fuel economy figures. This publication analyses the fuel efficiency gap and examines technologies available that could reduce that gap and improve fuel economy, as well as considering policy options for encouraging uptake of these technologies by vehicle manufacturers and, in some cases, by consumers themselves.
