对近期所研制的QN-1型全流消光式烟度计有效光路的测定进行了较为详细的叙述。通过试验方法确定了QN-1型消光式烟度计的有效光路。从试验结果分析,QN-1型消光式烟度计的有效光路定为15.88较为合理,汽油机的清新空气扫气压力为0.15MPa以下。通过ZDC-20kWNF125发动机台架重复试验看出,所得结果基本一致。
The recent development of the QN-1 full-flow extinction smoke meter to measure the effective optical path are described in more detail. The effective optical path of QN-1 extinction smoke meter was confirmed by the test method. From the test results, QN-1 extinction smoke meter effective optical path is set at 15.88 is more reasonable, gasoline engine clean air purge pressure of 0.15MPa or less. Through ZDC-20kWNF125 engine bench repeated test shows that the results are basically the same.
