UH’s Diesel Vehicle Research and Testing Facility, initiated in advance of the Bush administration’s Clean Air Nonroad Diesel Rule signed by the EPA in May, will be unveiled to the public during a ribbon-cutting ceremony with Houston Mayor Bill White at 3 p.m., Monday, June 28. In an effort to improve the region’s air quality, the City of Houston is providing $3.8 million to the University of Houston to test new technologies that will help reduce emissions from the city’s diesel fleet of 2,800 vehicles. The focus of the five-year project, headed by UH’s Department of Chemical Engineering, is to conduct diesel testing and data analysis, emission research and technology development. Cash and in-kind contributions from the university bring the total project cost to nearly $5 million.
