Naphtha as a Fuel for Internal Combustion Engines
Autor: Wonah Park
Publikováno v: International Journal of Automotive Technology. 22:1119-1133
Naphtha is a product obtained in the gasoline boiling range from different refinery components. Because naphtha is a less processed product of a refinery, its well-to-tank CO2 is lower than that of conventional gasoline or diesel. In addition, naphth

Performance of Naphtha in Compression Ignition Modes Using Multicomponent Surrogate Fuel Model
Autor: Yongrae Kim, Gyubaek Cho, Cheolwoong Park, Wonah Park
Publikováno v: International Journal of Automotive Technology. 21:843-853
Gasoline compression ignition (GCI) engines have been considered a promising technology for achieving diesel-like efficiency with less NOx and soot emissions than diesel engines. In recent research, naphtha has emerged as a suitable fuel for GCI owin

The effect of oxygenated fuel properties on diesel spray combustion and soot formation
Autor: Eric Kurtz, Wonah Park, Seunghyun Park, Rolf D. Reitz
Publikováno v: Combustion and Flame. 180:276-283
Diesel engines have advantages due to their potential for high fuel conversion efficiency. However, it is necessary to reduce pollutant emissions, particularly NOx and soot to meet emission mandates. Many studies have shown that oxygenated fuel addit
