摘要
本文通过对特定发动机试验所得结果的定性及定量探讨,论述验证了发动机四个标定参数:喷油轨压、喷油起始点、预喷油量、预喷与主喷间隔,在低功率段下,对燃烧噪声以及机外测得的声功率噪声的影响。
Experiments are conducted on diesel engines for qualitative and quantitative discussion about the influence of calibration parameters on acoustic of diesel engines.Effects of four injection parameters that include injection pressure of the common rail,injection time,the mass of pilot injection,and the intervals between the pilot injection and the main injection on combustion acoustic and sound power of engine surface noise are analyzed and verified.
