本文通过试验和模拟研究了丙醇异构体富集对天然气TFR发动机性能的影响。结果表明，正丙醇富集的TFR气瓶重整效果最好，异丙醇次之，天然气最差。缺火对正丙醇重整效果的影响最大，对异丙醇重整效果的影响较小，对天然气重整效果的影响最小。根据动力学分析，H2的生成速率取决于H、O、OH和HO2的生成速率。与异丙醇和甲烷相比，正丙醇在燃烧初期具有最快的H、O、OH和HO2自由基产生速率。对普通气缸的性能分析表明，正丙醇加浓的普通气缸的燃油消耗量最低。
This paper investigates the effects of propanol isomers enrichment on natural gas TFR engine via experiment and simulation. The results indicate that the reforming effect of TFR cylinder with n-propanol enrichment is the best, followed by that with iso-propanol, and with that of the natural gas being the worst. The impact of negative effect due to lack of fire was the most significant on the reforming effects with n-propanol enrichment, less on those with iso-propanol, and the least on those with natural gas. According to the kinetics analysis, the rate of H2formation depends on the rates of H, O, OH, and HO2formation. The n-propanol had the fastest production rate for H, O, OH, and HO2 radicals in the early stage of combustion, compared with iso-propanol and methane. The performance analysis of the normal cylinder shows that n-propanol enriched normal cylinders produced the lowest fuel consumption.
