    • An SOF measuring system (2) that can continuously measure SOF and a soot measuring system (3) that can continuously measure soot are connected with an exhaust gas line, the soot measuring system (3) comprises a diluter (4) that selectively dilutes either one of the exhaust gas and standard gas whose hydrocarbon concentration is known with diluent gas and extrudes it, a dilution ratio adjusting device (7) that can adjust a dilution ratio of the diluter (4), and a soot detector that continuously detects soot in the exhaust gas or the standard gas diluted by the diluter (4), and the SOF measuring system (2) can be connected with the diluter (4) so that an exhaust gas analyzer (1) can measure the hydrocarbon concentration in the standard gas diluted by the diluter (4).
    • 连续测量SOF的SOF测量系统(2)和连续测量烟灰的烟灰测量系统(3)与排气管线连接,烟灰测量系统(3)包括稀释器(4),其选择性地稀释 其中碳氢化合物浓度已知为稀释气体并将其排出的排气和标准气体之一,可调节稀释器(4)的稀释比率的稀释比率调节装置(7)以及连续检测碳烟的碳烟检测器 由稀释器(4)稀释的废气或标准气体以及SOF测量系统(2)可与稀释器(4)连接,使得废气分析仪(1)可测量标准气体 稀释液(4)稀释。
