燃烧分析试验中的数据修正问题

Data correction issues of combustion analysis test

阐述了在实际燃烧分析试验中,通过在柴油机的定时盘上粘贴一个有安全防护措施的铁片,给燃烧分析仪上增加一路脉冲信号来确定静态上止点的方法,以修正实际得到的缸压曲线的曲轴转角,使试验结果更加精准。

In the actual combustion analysis test,the combustion analyzer is added a pulse signal to determine the upper dead center by pasting a protective iron sheet on the engine timing,by which crank angles of the actual cylinder curve are corrected and the test results are more accurate.
