Engine Combustion, performance and emission characteristics of gas to liquid (GTL) fuels and its blends with diesel and bio-diesel

摘要

Crude oil price hikes, energy security concerns and environmental drivers have turned the focusudon alternative fuels. Gas to liquid (GTL) diesel is regarded as a promising alternative dieseludfuel, considering the adeptness to use directly as a diesel fuel or in blends with petroleumderiveduddiesel or bio-diesel. GTL fuel derived from Fischer-Tropsch synthesis is of distinctlyuddifferent characteristics than fossil diesel fuel due to its paraffinic nature, virtually zero sulfur,udlow aromatic contents and very high cetane number. GTL fuel is referred to as a “clean fuel”udfor its inherent ability to reduce engine exhaust emission even with blends of diesel and Biodiesel.ududThis paper illustrates feasibility of GTL fuel in context of comparative fuel properties withudconventional diesel and bio-diesels. This review also describes the technical attributes of GTLudand its blends with diesel and bio-diesel focusing their impact on engine performance andudemission characteristics on the basis of the previous research works. It can introduce anudefficacious guideline to devise several blends of alternative fuels, further development ofudengine performance and to constrain exhaust emission to cope with the relentless efforts toudmanufacture efficient and environment friendly powertrains.
