Abstract

This report describes the laboratory effort toward further evaluating the emissions and fuel economy performance of the advanced emissions control technology engine configuration optimized in Phase II of this project. An additional intent of Phase III was to obtain data toward establishing a linking mechanism between data generated previously using various different operating cycles and test procedures. Project tasks included: examination and overhaul of the engine used during Phase II, nine-mode and transient cycle emissions and fuel consumption evaluations, and recommendations for future work. For the transient cycle evaluations, which included light-duty FTP and experimental CAPE-21 cycles, the engine was installed into an appropriate heavy-duty truck. All transient cycle emissions and fuel consumption evaluations were conducted on a heavy-duty chassis dynamometer and utilized a truck-size constant volume sampler.
