EXHAUST GAS SAMPLING APPARATUS

The present invention is provided with a control device that sets a split flow ratio that is a ratio of the flow rate of the diluted exhaust gas to be sampled through a diluted exhaust gas sampling flow path to a flow rate of a diluted exhaust gas flowing through a CVS, wherein the control device us...

Beschreibung
Zusammenfassung:	The present invention is provided with a control device that sets a split flow ratio that is a ratio of the flow rate of the diluted exhaust gas to be sampled through a diluted exhaust gas sampling flow path to a flow rate of a diluted exhaust gas flowing through a CVS, wherein the control device uses the flow rate (QCVS) of the diluted exhaust gas flowing through the CVS or a value (TCVS or PCVS) related to the flow rate (QCVS) of the diluted exhaust gas to set the split flow ratio (Qsamp/QCVS) so as to make a flow velocity (Vfilter) of the diluted exhaust gas flowing into an analytical device equal to a predetermined value.
