| 摘 要： | 在1台电控高压共轨增压发动机上,不改变原机结构,采用甲醇—柴油混合燃烧的方式,进行燃烧排放特性分析。结果表明:在相同转速下,发动机的当量燃油消耗率随负荷的增加而降低;随着甲醇含量增加,发动机的最高燃烧压力、最高燃烧放热率和最高燃烧温度都逐渐升高;中低负荷时,发动机的CO和HC排放随着负荷的升高而减小,燃用混合燃料时较燃用柴油略有升高,且甲醇含量越高升高越多;燃用混合燃料时发动机的NO_x和炭烟排放较燃用柴油时有所降低,且随着负荷的升高而增大。

| Abstract: | On an electronic control high-pressure common rail turbocharging engine,the combustion and emission performance of methanol-diesel blended fuel were analyzed.The results show that the equivalent brake specific fuel consumption(EBSFC) decreases with the increase of load at the same speed.The maximum combustion pressure,the peak heat release rate and the maximum combustion temperature increase with the increase of methanol fraction.At low and medium loads,the CO and HC emission reduce with the increase of load,but are higher than those of diesel and the phenomenon will be strengthened with the increase of methanol fraction.The NO_x and soot emission increase with the increase of load and are lower than those of diesel. |
