嵩上げして測定する排ガス濃度の測定装置。 An exhaust gas introduction pipe is connected via a first valve to the upstream side of a dilution tunnel through which dilution gas flows at a constant flow rate, a gas sampling pipe is opened on the downstream side, and the gas sampling pipe is connected via a second valve. In the exhaust gas concentration measuring device connected to the gas sampling device, a supply pipe supplies a standard gas with a known concentration, which is the same component as the component to be measured in the exhaust gas, to the upstream side of the dilution tunnel through a third valve. and a bypass pipe for sending the standard gas to the gas sampling device via a fourth valve, and by alternately supplying the standard gas to the dilution tunnel and the bypass pipe, An exhaust gas concentration measuring device that measures components by bulking them up with standard gas.
