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。
关键词： 喷油轨压;;预喷油量;;预喷与主喷间隔
Abstract: 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.
Keywords: Injection Pressure of Common
Rail;Mass of Pilot Injection;Interval between Pilot Injection and Mail
Injection
