초록
As regulations on exhaust gas emitted from all industrial fields are being strengthened, technologies for reducing harmful gases, such as nitrogen oxides (NOx) and particulate matter (PM), emitted from high-efficiency diesel engines used as various power sources, are being developed and applied. Post-treatment technologies, such as selective catalytic reduction (SCR), and diesel particle filter (DPF) are generally applied, but they are not easy to implement in agriculture and fishery sectors and others due to system modification and considerable cost. Therefore, in this study, we confirmed the applicability of diesel emulsion fuel, which does not require a separate additional system, and could simultaneously reduce NOx and PM by identifying combustion and exhaust character-istics, based on exhaust gas recirculation (EGR) application in a commercial diesel engine. Compared to diesel oil (DO), the NOx emission from diesel-water emulsion (DWE) was lesser by 15.9% under the condition without EGR, and by 22.3% under the condition with EGR; and the smoke emission from DWE was lesser by 62.1% under the condition without EGR, and by 73.0% under the condi-tion with EGR.
Abstract
As regulations on exhaust gas emitted from all industrial fields are being strengthened, technologies for reducing harmful gases, such as nitrogen oxides (NOx) and particulate matter (PM), emitted from high-efficiency diesel engines used as various power sources, are being developed and applied.

Therefore, in this study, we confirmed the applicability of diesel emulsion fuel, which does not require a separate additional system, and could simultaneously reduce NOx and PM by identifying combustion and exhaust character-istics, based on exhaust gas recirculation (EGR) application in a commercial diesel engine.
