天然气/柴油双燃料发动机燃烧与排放特性的试验研究

Hybrid Fule Engine Combustion and Emission Charater

在单缸喷式柴油机上进行的柴油 -LPG双燃料发动机燃烧和排放试验结果表明 ,双燃料发动机没有出现功率损失的现象 ,热效率在高负荷时有一定改善 ;着火滞燃期比纯柴油长 ,燃烧持续期缩短 ;同时 ,双燃料发动机能降低N0 X 和微粒排放。

It is shown that no power loss exists in power ability of hybrid fuel engine. A certain improvement of heat efficiency is obtained under the condition of high load, and 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, and direct fuel injection diesel engine. It is shown by emission test that the hybrid fuel engine can provide an effective way to reduce NOX and fine-grained emission.
