Book Description
More than 1/4 of cars & 1/3 of light trucks on U.S. roadways have one or more tires underinflated 8 pounds per square inch (PSI) or more below the level recommended by the vehicle manufacturer. A decrease in tire pressure can be caused by poor maint., driving habits, punctures, road conditions, & the quality of material used in tire construction. Under normal driving conditions, air-filled tires can lose from 1 to 2 psi per month as air permeates through the tires. The following questions are addressed: What is the impact of tire underinflation on safety & fuel economy, & what actions has the fed. gov¿t. taken to promote proper tire inflation?; & What technologies are currently available to reduce underinflation & what are their implications for safety & fuel economy? Illus.

Book Description
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.
