TL;DR: A good correlation was found between the PM index and PM mass and number emissions for all vehicle/fuel combinations with the total aromatics group being a significant contributor to the total PM index followed by naphthalenes and indenes.
Journal ArticleDOI
Regulated, greenhouse gas, and particulate emissions from lean-burn and stoichiometric natural gas heavy-duty vehicles on different fuel compositions
Georgios Karavalakis,Georgios Karavalakis,Maryam Hajbabaei,Yu Jiang,Yu Jiang,Jiacheng Yang,Jiacheng Yang,Kent C. Johnson,Kent C. Johnson,David R. Cocker,David R. Cocker,Thomas D. Durbin,Thomas D. Durbin +12 more
TL;DR: In this article, the gaseous and particulate matter (PM) emissions from three heavy-duty natural gas vehicles, including a lean-burn bus with an oxidation catalyst and two stoichiometric Class 8 trucks with three-way catalysts were evaluated.
Journal ArticleDOI
Impact of natural gas fuel composition on criteria, toxic, and particle emissions from transit buses equipped with lean burn and stoichiometric engines
TL;DR: In this article, the impacts of varying natural gas composition on the exhaust emissions from different technology transit buses were investigated on a chassis dynamometer over the CBD (Central Business District) cycle on six different gas blends each.
Journal ArticleDOI
The effect of natural gas composition on the regulated emissions, gaseous toxic pollutants, and ultrafine particle number emissions from a refuse hauler vehicle
Georgios Karavalakis,Maryam Hajbabaei,Thomas D. Durbin,Kent C. Johnson,Zhongqing Zheng,Wayne Miller +5 more
TL;DR: In this article, the authors investigated the impact of varying natural gas composition on exhaust emissions from a waste hauler equipped with a 2002 Cummins 8.3L, C Gas Plus, lean burn, spark ignited natural gas engine and an oxidation catalyst while operated on the William H. Martin Refuse Truck Cycle on a chassis dynamometer.
Journal ArticleDOI
Evaluation of the impacts of biodiesel and second generation biofuels on NO(x) emissions for CARB diesel fuels.
Maryam Hajbabaei,Kent C. Johnson,Robert Okamoto,Alexander Mitchell,Marcie Pullman,Thomas D. Durbin +5 more
TL;DR: It appears that the impact of biodiesel on nitrogen oxides emissions might be a more important consideration when blended with CARB diesel or similar fuels, and that some form of NO(x) mitigation might be needed for biodiesel blends with such fuels.
