Using a supplemental fuel spray system, the catalytic reduction of NOx from the exhaust of a diesel engine has been demonstrated. The mechanism for NOx reduction will be discussed by reviewing the preliminary work conducted to evaluate the fundamental interaction between NO, oxygen and hydrocarbons using a fixed-bed flow system and IR spectroscopy. Based on this preliminary work, the incorporation of a copper containing catalyst system coupled with a diesel fuel spray system, has been shown to reduce NOx by 30% at exhaust temperatures around 450°C. Using this technology, a total system for the “simultaneous” reduction of both particulates and NOx, based on engine operating conditions, is proposed.
