在4100QBZL直列增压中冷型柴油机上燃用F-T柴油，对比分析了F-T柴油与0#柴油的燃烧与振动特性。结果表明：燃用F-T柴油后，缸内压力略低于0#柴油，压力升高率有较大程度的降低。低负荷下燃烧始点有较大提前，高负荷下稍有推后。 F-T柴油放热平缓，预混燃烧放热峰值降低，扩散燃烧放热峰值有所升高。在不同工况下F-T柴油缸盖振动加速度信号的幅值均低于0#柴油。振动加速度在200~8000 Hz范围内都有较大的幅值，高频成分的能量较0#柴油少。

An experiment was undertaken on 4100QBZL turbocharged diesel engine to compare the combustion and vibration characteristics of diesel engine fueled with Fischer-Tropsch (F-T) diesel fuel and 0# diesel fuel. The result show that:when fueling with Fischer-Tropsch(F-T) diesel fuel, the cylinder pressure is slightly lower than 0# diesel oil, and the rate of pressure rise decreases greatly. Under low load the ignition timing advances, while under high load delays. F-T diesel fuel has smooth heat liberation, lower peak value of premixed burning rate and higher peak value of diffusion burning rate than 0# diesel fuel. In different cases, the vibration acceleration amplitude of cylinder head is less and mainly concentrated range 200Hz from 8000 Hz. High frequency energy is less than 0# diesel fuel.
