Journal ArticleDOI
The effect of biodiesel and bioethanol blended diesel fuel on nanoparticles and exhaust emissions from CRDI diesel engine
Hwanam Kim,Byungchul Choi +1 more
TL;DR: In this article, the authors studied the characteristics of the particle size distribution, reaction characteristics of nanoparticles on the catalyst, and exhaust emission characteristics when a common rail direct injection (CRDI) diesel engine is run on biofuel-blended diesel fuels.
Journal ArticleDOI
Effect of ethanol-diesel blend fuels on emission and particle size distribution in a common-rail direct injection diesel engine with warm-up catalytic converter.
Hwanam Kim,Byungchul Choi +1 more
TL;DR: In this paper, the exhaust gas from a common-rail direct injection diesel engine was investigated both upstream and downstream warm-up catalytic converters (WCC) and three different types of ultra-low sulfur fuels (ethanol-diesel blend, ethanol-diesels blend with cetane improver and pure diesel) were tested in this study.
Journal ArticleDOI
Effect of diesel fuel blend with n-butanol on the emission of a turbocharged common rail direct injection diesel engine
Byungchul Choi,Xiaolong Jiang,Young Kwon Kim,Gilsung Jung,Chun-Hwan Lee,Inchul Choi,Chi Sung Song +6 more
TL;DR: In this article, the effect of diesel fuel blend with n-butanol on the emission of turbocharged common rail direct injection (CRDI) diesel engine and to compare the results with the neat diesel fuel operation case were investigated.
Journal ArticleDOI
Development of Highly Active Bifunctional Electrocatalyst Using Co3O4 on Carbon Nanotubes for Oxygen Reduction and Oxygen Evolution.
TL;DR: Co3O4/CNTs are promising high-performance and cost-effective bifunctional catalysts for ORR and OER because of their overall superior catalytic activity and stability compared with 20 wt% Pt/C and RuO2, respectively.
Journal ArticleDOI
Au Decorated ZnO hierarchical architectures: Facile synthesis, tunable morphology and enhanced CO detection at room temperature
S. Arunkumar,Tian-Feng Hou,Young-Bae Kim,Byungchul Choi,Su Han Park,Seunghun Jung,Dong-Weon Lee +6 more
TL;DR: In this paper, a highly selective and sensitive gas sensing material was prepared by decorating gold nanoparticles on zinc oxide (ZnO) nanostructure, which exhibited excellent sensitivity (S R ǫ ∼15 toward 50 ppm ) at 35°C with an excellent response (Γ RES ∼8−s) and recovery time.
