For advanced diesel engines to achieve high fuel economy and ultra low emissions in the 21st century, an integrated NOx and particulate matter emissions control system is required. This book contains 45 landmark SAE papers on the topic of measurement and control of diesel nitrogen oxide emissions, focusing on these subjects: Measurement techniques; Fundamentals of NOx formation in the engine; Exhaust gas recirculation (EGR); Aftertreatment controls; Fuel injection variables that lower NOx emissions; Fuel effects on NOx and particulate emissions. Diesel Nitrogen Oxide Emissions: Landmark Research 1995-2001 contains the latest research and development findings that will guide engineers to low nitrogen oxide emissions in future engines.
