摘要:
基于单轴并联式混合动力试验平台，以0号柴油、煤基费托合成柴油(F-T柴油)和聚甲氧基二甲醚(PODE)为基础燃油，研究0号柴油、F-T柴油及F90P10(PODE体积分数为10%)和F80P20(PODE体积分数为20%)4种燃油在不同的起动瞬态变化条件下的燃烧和排放特性，分析F-T柴油/PODE掺混燃料对混合动力柴油机起动特性的影响．结果表明：与0号柴油相比，燃用F-T柴油时起动燃烧首循环的缸内压力、放热率和压力升高率峰值都有所降低，燃烧持续期增大；冷起动工况下，CO、NOx排放峰值在24V原机起动时分别降低42.3%和32.4%，800r/min拖动起动时分别降低50.9%和55.0%，而碳烟峰值略有升高；热起动工况下，CO、NOx和碳烟排放峰值在24V原机起动时分别降低66.4%、64.5%和34.4%，800r/min拖动起动时分别降低57.0%、48.6%和24.8%．与F-T柴油相比，随着PODE体积分数的增大，起动中CO和NOx排放峰值略微增大，但碳烟排放大幅降低，弥补F-T柴油在冷起动时碳烟排放升高的不足．
Abstract:
Based on a single-shaft parallel hybrid diesel engine test platform using 0# diesel，coal-based fischer-tropsch(F-T diesel)and polymethoxymethylene dimethyl ethers(PODE)as the basic fuels，the combustion and emission char-acteristics of the engine fueled with 0# diesel，F-T diesel，F90P10(PODE volume fraction is 10%)and F80P20(PODE volume fraction is 20%)were experimentally studied under different starting transient conditions. The effect of F-T diesel/PODE blended fuel on starting performance of the hybrid-powered diesel engine was ana-lyzed. The results show that when the F-T diesel is used，the peak values of in cylinder pressure，heat release rate and pressure rise rate in the first cycle of start-up are decreased，and the combustion duration is increased. Under the condition of cold start，the peak values of CO and NOx are reduced by 42.3% and 32.4% respectively at orig-inal 24V start condition，and 50.9% and 55.0% respectively at 800r/min starting condition，while the soot peak slightly increases. Under hot start condition，the emission peaks of CO，NOx and soot decrease by 66.4%，64.5% and 34.4% at original 24V start condition，and 57.0%，48.6% and 24.8% at 800r/min start condition，respectively. Compared with F-T diesel，with the increase of PODE ratio，the peak value of CO and NOx emis-sions increases slightly during the start-up process，but the soot emission decreases significantly，which can make up for the deficiency of F-T diesel in the cold start.
