摘要
介绍了柴油机负荷烟度试验ELR的测试规程,分析了Bessel算法在ELR试验中的作用及其设计流程。利用MATLAB软件开发了适于ELR试验的Bessel滤波器,将其应用于发动机台架试验的实测值,得到ELR试验的最终排放烟度。
The testing regulation of diesel ELR （ European Load Response Test） is introduced and the function and design of Bessel arithmetic in ELR were analyzed. Bessel filter fit for ELR was developed by MATLAB and applied to the measured data of engine bed test. At last the emission smoke of ELR was calculated.
