GTL is a liquid state in the normal temperature and pressure. It has high cetane number and other properties of it are comparable with that of diesel fuel. Therefore GTL can be alternative fuel of compression ignition engine. Furthermore, there is little sulfur and aromatic, so clean exhaust emission of diesel engine fueled with GTL can be expected.<br/> In this study, engine performances and exhaust emissions characteristics of compression ignition engine fueled with GTL were investigated by comparison with diesel fuel.<br/> Diesel engine could be operated fueled with GTL without any special modify for the test engine. With the high cetane number of GTL, the ignition lag was shorter. and the combustion started earlier than that of diesel fuel Brake thermal efficiency operated with GTL increased at middle load conditions, because incomplete combustion emission such as CO and THC were lower than that of diesel fuel operation. NOx emission operated with GTL was comparable to diesel fuel. and there was a little decrease at high load. With GTL, soot emission was lower than with diesel fuel at above middle load condition. It seemed to be a reason of soot reduction Ihallhere was little sulphur contained in GTL.<br/>
