摘要
本文对引燃柴油供油提前角和天然气替代柴油率对天然气 /柴油双燃料发动机排放性能的影响进行了试验研究 .结果表明 ,随引燃柴油供油提前角的变更和天然气替代柴油率的变化 ,发动机排放物中 THC、 CO和 NOx有较大变化 .综合考虑发动机的排放性能及动力性等 。
The pilot fuel supply advance angle and the substitution ratio of natural gas to diesel are two important factors influencing the dualfuel(natural gas and diesel) engine emission. Some experiments were carried out to determine the effects of these two factors on the dualfuel engine emission. The results shows that the dualfuel engine emission pollutants including THC, CO and NOx change greatly with the variation of these two factors. Based on the dualfuel engine emission characteristics, dynamic performance, et al. the optimal range of the pilot fuel supply advance angle and the substitution ratio of natural gas to diesel were obtained.
