Final Summary Report on Project 3310 Marine Diesel Exhaust Emissions (AlternativeFuels)

摘要

This report summarizes the results of a 5-year study to ascertain the magnitudeof emission problems from Coast Guard and commercial vessels; to develop methodology applicable for use on small vessels by using portable emission analyzers, and to examine various potential means of reducing excessive emissions. During this project, the Coast Guard RD Center tested eight vessels (of six types); and the Volpe National Transportation Systems Center tested six Coast Guard vessels (of five types) operating on the West Coast. Of the 14 vessels tested, eight were found to exceed the proposed NOx limits, although some by very small amounts.
