So-called clean-diesel technology is meeting U.S. limits for nitrogen oxide emissions by a substantial margin, according to the nonprofit Coordinating Research Council Inc.
CRC's new study was conducted in cooperation with the Health Effects Institute, a nonprofit group funded primarily by the U.S. Environmental Protection Agency.
The report finds that clean diesels built after 2009 cut exhaust NOx more than 60% compared with previous-generation engines from 2007. A previously reported portion of the analysis found a 99% drop in particulate emissions since 2004.
The aim of the continuing five-year study is to measure the effectiveness of clean diesels and look for "unintended emissions" caused by the technology.
CRC says more than 11% of commercial trucks and buses currently on American roads are equipped with 2010 or newer clean-diesel systems. In January, heavy-duty diesel vehicles must meet new federal fuel economy and carbon dioxide standards.
