| 摘 要： | 对在单缸直喷式柴油机上进行的柴油——LPG双燃料发动机燃烧和排放特性研究表明，双燃料发动机动力性没有出现功率损失的现象，热效率在高负荷时有一定的改善；着火滞燃期比纯柴油长，燃烧持续期缩短。排放试验表明，双燃料发动机为降低NOx和微粒排放提供一种有效途径。

Test and Study on
Combustion and Emission Character of Hybrid Diesel-LPG Fuel Used in Direct Fuel Injection
Diesel Engine |

| Abstract: | It is shown that no power loss is existed in power ability of hybrid fuel engine, a certain improvement of heat efficiency is obtained under the condition of high load, the flaming hysteresis time is longer than that of diesel fuel used solely and the duration of flaming is shorter, by studying on combustion and emission character of hybrid diesel - LPG fuel used in a single cylinder, direct fuel injection diesel engine. It is shown by emission test that the hybrid fuel engine can provide an effective way to reduce NO x and fine - grained emissions. |
