| 摘 要： | 测量了发动机燃烧过程,分析了燃烧过程中出现的压力波动现象。研究表明,随着转速、负荷、供油提前角等参数的变化,柴油机的滞燃期发生了改变,从而影响了滞燃期内产生可燃混合气的量,导致了缸内压力波动。

A Research on the Characteristics of Combustion Pressure Fluctuation in Diesel Engine |
| |
| Abstract: | The combustion characteristics of the diesel engine are measured and the pressure fluctuation in cylinder is analyzed. It is found that the delay period is changed when the engine speed and load and injection timing are changed, which is the fundamentality to the pressure fluctuation in cylinder.To control delay period accurately can reduce combustion pressure oscillation effectively caused by speed and load and injection timing. |
