Abstract
To provide for diesel fuel diversification in the future, it is necessary to clarify the effects of each fuel specification on the combustion and emissions characteristics of a state-of-the-art engine. Fischer-Tropsch synthetic Diesel (FTD) fuels have characteristics of higher Cetane number and very low poly-aromatic hydrocarbon content. In this work, the effect of specific FTD fuel characteristics on diesel combustion and emissions were firstly compared with diesel fuel by means of a multi cylinder engine and a single cylinder transparent engine. From these findings, engine modifications for neat FTD fuel were then studied to improve both emissions and fuel consumption.
