San Diego's Achates Power, a startup developing a radical new design for a diesel-powered truck engine, is blowing its own air horn today about its progress in demonstrating significant improvements in the efficiency and performance of its engine. Through a series of tests that began just over a year ago, Achates says its prototype has shown improved fuel efficiency, while also meeting the new EPA 10 emission standards for heavy trucks, which seek a seven to 20 percent reduction in greenhouse gas emissions by 2018.
