Combustion and Emissions Characteristics of GTL Fueled Diesel Engines

Abstract

GTL fuels have many advantages as an alternative cleaner diesel fuel. Higher Cetane number and the absence of Poly-Aromatic Hydrocarbon content, which are the principal properties of GTL fuels, have a potential to reduce HC and PM emissions. Further the absence of sulfur content will result not only in the PM emission reduction, but also in the deterioration restraint of aftertreatment catalyst activities. In this study, the effects of GTL fuels on combustion and emissions characteristics of the latest diesel engines were evaluated. In addition to these tests, a single-cylinder engine with optical access was used for the combustion analysis.
