The Advanced Petroleum-Based Fuels Program Evaluation of EC-Diesel and Diesel Particulate Filters in Southern California Vehicle Fleets
The EC-Diesel and particulate filter combination greatly reduced the particulate matter, hydrocarbon, and carbon monoxide emissions of all vehicles tested in the program to date. Particulate matter reductions greater than 98% were achieved. For several vehicles tested, the PM and HC emissions were less than background levels. Based on preliminary statistical analysis, there is 95%+ confidence that EC-D and particulate filters reduced emissions from three different types of vehicles. A fuel consumption penalty was not detectable using the current test procedures and chassis dynamometer laboratory. Test vehicles equipped with the CRT and DPX particulate filters and fueled with EC-Diesel fuel have operated reliably during the program start-up period.

The advanced tangentially fired combustion techniques for the reduction of nitrogen oxides (NOx) emissions from coal-fired boilers demonstration project: A DOE assessment
This document serves as a DOE post-project assessment of a project in Round 2 of the Department of Energy's Clean Coal Technology (CCT) Program: ``Advanced Tangentially Fired Combustion Techniques for the Reduction of Nitrogen Oxides (NO{sub x}) Emissions From Coal-Fired Boilers Demonstration Project''. In September 1990, Southern Company Services entered into an agreement to conduct the study, with Gulf Power Company providing the 180 megawatt electric (MWe) host site and ABB C-E Services Inc. providing the technology to be demonstrated. This project was undertaken to evaluate the nitrogen oxides (NO{sub x}) reduction potential of several variations of the Low NO{sub x} Concentric Firing System (LNCFS{trademark}) when applied to tangentially fired (T-fired) boilers. The project consisted of replacing the existing coal and air nozzles with new nozzles and adding overfire air. Three versions of the LNCFS system were tested: Level 1 consisted of new coal nozzles and close-coupled overfire air; Level 2 used the same burners but separated the overfire air; and Level 3 used both close-coupled and separated overfire air. The performance objectives were as follows: (1) to determine the short-term and long-term NO{sub x} emissions reduction capabilities and impact on unit performance of the low-NO{sub x} combustion technologies of …

[Aerial photograph of the Texas Motor Speedway Dirt Track]
Aerial photograph of the Texas Motor Speedway Dirt Track at the Southern Bleacher Classic held at night. The track is oval shaped with a large swath of dirt at its center surrounded by a road lined by a short white wall. Outside this wall is a line of stands around the left side of the track and a row of parked trucks along the right side of the track. According to the label on the photograph's back, a crowd of 20,400 fills the stands. Light on tall poles stand around the inner and outer areas of the track. To the left and outside of the track are two large buildings that sit alongside some of the stands that face the track. The rest of the photo is dark and dotted with yellow, orange, and red balls of light.

[Aerial view of NASCAR Winston Cup drivers racing]
Aerial photograph of NASCAR Winston Cup drivers racing before the DIRECTV 500 race held at Texas Motor Speedway on April 2, 2000. The bottom third of the photo is filled by cozens of stands packed with people watching the race below them, only a tall fence lien separating the onlookers from the road. The middle third of the photo is occupied by the racing circuit, its roads wrapping around large patches of grass with logos like that of DIRECTV, Albertsons, and Sprint painted onto the grass. The cars of the race all speed along the part of the circuit closest to the stands of people watching the vehicles. The top third of the photo is filled with parked vehicles including large trucks and cars, plus a lien of tents that sit in front of the far side of the racing circuit. According to the label on the back of the photo, Dale Earnhardt Jr. won the race, making it his first Winston Cup victory.
