摘　　要：研究了增压直喷柴油机燃用柴油-GTL柴油混合燃料的性能和排放特性。在未对原机作任何调整和改动下,研究了不同混合比柴油-GTL柴油的混合燃料对功率、油耗、烟度和NOx排放的影响。结果表明:柴油机燃用GTL柴油后功率和油耗有所下降,其变化程度与燃料之间的掺比有关,但燃料G50的动力性最好,优于常规柴油,经济性与燃料G100相当。随着GTL柴油掺混比的增加,柴油机烟度和NOx排放呈大幅下降趋势。柴油机燃用GTL柴油时,可适用更高的EGR率。The performance and emission characteristics were investigated when a TDI （turbocharged direct-injected） diesel engine was fueled with the blend of diesel fuel and GTL （gas to liquids） fuel. The influence of the blend fuel with different blending ratio on power, fuel consumption, smoke and NOx emission was investigated without any engine modification. The results show that the power and fuel consumption are reduced when the engine is fueled with GTL fuel, the lowering degree of the power and fuel consumption relates to the fuel blending ratio, but the power characteristic of G50 fuel is better than that of the traditional diesel fuel and the fuel economy of G50 is similar to G100. With the rise of the blending ratio of GTL fuel, the smoke and NOx emission tend towards significant reduction. The EGR rate of the engine can be enlarged when GTL diesel fuel is used as alternative fuel.
