Nitrous oxide in diesel aftertreatment systems including DOC, DPF and urea‐SCR

Autor: Chong-Pyo Cho, Youngdug Pyo, Jinyoung Jang, Youngmin Woo, Youngjin Shin, Ahyun Ko, Gangchul Kim, Yongjin Jung

Publikováno v: Fuel. 310:122453

The formation of Nitrous oxide (N2O) over urea-based selective catalytic reduction (SCR) systems was scrutinized using exhaust gases from a 3.4-liter non-road diesel engine. Four catalysts were used for the SCR systems; Cu-zeolite (Cu/Fe = 4), Fe-zeo

Experimental Evaluation of EGR and Fuel Injection Pressure on Combustion, Size-resolved Nano-particle and NOx Emissions Characteristics in an Advanced Light-duty Diesel Engine

Autor: Ahyun Ko, Cha Lee Myung, Jung Won Han, Wonwook Jang, Jung Been You, Dong Young Jin, Simsoo Park, Sungha Baek

Publikováno v: Transactions of the Korean Society of Automotive Engineers. 22:8-15

In order to satisfy stringent future emission regulation in diesel engines, systematic approaches to mitigate the harmful exhaust emissions were developed, such as engine hardware, fuel injection equipment, engine control, and after-treatment system.

Review on characterization of nano-particle emissions and PM morphology from internal combustion engines: Part 1

Autor: Sunwoo Park, Cha Lee Myung, Ahyun Ko

Publikováno v: International Journal of Automotive Technology. 15:203-218

This paper is review of the characterization of exhaust particles from state-of-the-art internal combustion engines. We primarily focus on identifying the physical and chemical properties of nano-particles, i.e., the concentration, size distribution,
