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
Gasoline Particulate Filters as an Effective Tool to Reduce Particulate and Polycyclic Aromatic Hydrocarbon Emissions from Gasoline Direct Injection (GDI) Vehicles: A Case Study with Two GDI Vehicles
Jiacheng Yang,Jiacheng Yang,Patrick Roth,Patrick Roth,Thomas D. Durbin,Thomas D. Durbin,Kent C. Johnson,Kent C. Johnson,David R. Cocker,David R. Cocker,Akua Asa-Awuku,Akua Asa-Awuku,Rasto Brezny,Michael R. Geller,Georgios Karavalakis,Georgios Karavalakis +15 more
TL;DR: The results showed dramatic reductions in particulate matter (PM) mass, black carbon, and total and solid particle number emissions with the use of GPFs for both vehicles over the LA92 and US06 cycles.
Journal ArticleDOI
Characterizing emission rates of regulated pollutants from model year 2012+ heavy-duty diesel vehicles equipped with DPF and SCR systems.
Yu Jiang,Jiacheng Yang,David R. Cocker,Georgios Karavalakis,Kent C. Johnson,Thomas D. Durbin +5 more
TL;DR: PM, THC, and CO emissions were found to be very low for most of the testing conditions, due to the presence of the DPF/SCR aftertreatment system, and were comparable to background levels in some cases.
Journal ArticleDOI
Impacts of dimethyl carbonate blends on gaseous and particulate emissions from a heavy-duty diesel engine
Jiacheng Yang,Yu Jiang,Georgios Karavalakis,Kent C. Johnson,Sachin Kumar,David R. Cocker,Thomas D. Durbin +6 more
TL;DR: In this paper, Dimethyl carbonate (DMC) is an oxygenate fuel that can be used in petroleum diesel that is been lightly studied, but could provide significant reductions in particulate matter (PM) emissions from internal combustion engines.
Journal ArticleDOI
Impacts of gasoline aromatic and ethanol levels on the emissions from GDI vehicles: Part 1. Influence on regulated and gaseous toxic pollutants
Jiacheng Yang,Jiacheng Yang,Patrick Roth,Patrick Roth,Thomas D. Durbin,Thomas D. Durbin,Georgios Karavalakis,Georgios Karavalakis +7 more
TL;DR: In this paper, the authors investigated the impacts of varying aromatic and ethanol levels on the exhaust emissions of five gasoline direct injection (GDI) vehicles using a test fleet consisting of 2016 to 2017 model year Tier 3 vehicles operated over the LA92 drive cycle.
