Ford Motor Co. and the EPA are expected to reveal this week an agreement on development and possible commercialization of a new kind of diesel-powered engine, according to a Jan. 24 report in Automotive News. An agency official said last week that an announcement is planned for Friday, Jan. 28, at the EPA's emissions laboratory in Ann Arbor, Mich. No details were available, but EPA officials said last year they were negotiating with a major automaker to use diesel technology that agency engineers have been developing. The engineers say the diesel produces lower oxides of nitrogen emissions without costly, power-sapping aftermarket devices, the report said.
