Characterization Of Real-World Particle Number Emissions During Re-Ignition Events From A 2010 Light-Duty Hybrid-Electric Vehicle, Matthew Beach Conger
Characterization Of Real-World Particle Number Emissions During Re-Ignition Events From A 2010 Light-Duty Hybrid-Electric Vehicle, Matthew Beach Conger
Graduate College Dissertations and Theses
Despite the increasing popularity of hybrid-electric vehicles (HEVs), few studies have quantified their real-world particle emissions from internal combustion engine (ICE) re-ignition events (RIEVs). RIEVs have been known to occur under unstable combustion conditions which frequently result in particle number emission rates (PNERs) that exceed stabilized engine operation. Tailpipe total PN (5 to 560 nm diameter) emission rates (#/s) from a conventional vehicle (CV) and hybrid electric vehicle (HEV) 2010 Toyota Camry were quantified on a 50 km (32 mi) route over a variety of roadways in Chittenden County, Vermont using the Total On-board Tailpipe Emissions Measurement System (TOTEMS).
