EPA: Engine makers to meet 2007 clean-diesel regs

Engine manufacturers are on target to introduce diesel engines that will meet tough emissions standards in 2007, according to a U.S. Environmental Protection Agency (EPA) report. The EPA met with nearly 30 companies to compile its review of the industry's progress to implement clean-diesel technologies by 2007. Once the 2007 program is fully implemented, 2.6 million tons of smog-causing nitrogen oxide (NOx) emissions will be reduced each year, according to the EPA. The review shows that engine manufacturers will be able to introduce engines using filters that reduce harmful particulate matter emissions by more than 90%. Using ultra-low sulfur diesel fuel, the new engines will reduce NOx emissions by 50% and will substantially contribute to air quality improvement across the country. "EPA's clean-diesel standards are an important reason Americans can expect air quality to continue to improve in the years ahead," said EPA Assistant Administrator Jeff Holmstead.
