Characterization of Toxicologically Relevant Compounds From Diesel Emissions: Phase II

A light-duty diesel engine fitted with a common-rail fuel injection system was calibrated on several alternative type test fuels to achieve low engine-out oxides of nitrogen (NOx) exhaust emissions. In conjunction with the Low NOx operating conditions, a Diesel Oxidation Catalyst and a catalyzed Diesel Particulate Filter were sized for the engine and exhaust species characterized. The exhaust was…
