디젤연료 첨가제가 기관성능에 미치는 영향

Studies were performed with two commonly used additive metals. cerium and iron. with a conventional diesel fuel in order to investigate fuel additive effects on extaust emissions and combustion characteristics. Measurements were made on a single cylinder direct injection engine and included total particulate mass. NO_x. HC and cylinder gas pressure. The cerium and iron based additive reduced the particulate emissions and hydrocarbon by 23~35% and 14%. respectively. Both additives were found tohave the least effect on cylinder gas pressure.
