This project develops and verifies models for emissions from heavy-duty diesel engines (e.g. Class 8 trucks and buses). Heavy-duty vehicle modal emission models have not yet been developed to date primarily due to the lack of appropriate second-by-second emissions data. So under a current project sponsored by the U.S. EPA, an emission trailer is being developed at UC Riverside CE-CERT that can be attached to a number of heavy-duty rigs to measure instantaneous emissions (including particulates) in-situ. Using the emissions data, a heavy-duty diesel modal emissions/energy model will be developed and verified. The model will be integrated with PATH's SmartAHS to evaluate numerous automation scenarios that involve passenger cars, buses, and heavy-duty trucks. The model and evaluation results will be completed prior to Demo 2002. The model will be combined with control simulation tools to evaluate ITS scenarios such as adaptive cruise control.
