MEASURING DEVICE FOR PARTICULATE AMOUNT, MEASURING METHOD OF PARTICULATE AMOUNT, AND EXHAUST EMISSION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a measuring device of a particulate amount, a measuring method of the particulate amount, and an exhaust emission control device capable of accurately estimating the particulate amount collected by a diesel particulate filter.

SOLUTION: The measuring device of the particulate amount is mounted between an internal combustion engine and the diesel particulate filter for purifying exhaust gas discharged from the internal combustion engine, and measures the content of the particulates contained in the exhaust gas. The measuring device comprises an inlet section for introducing a part of exhaust gas as a sample gas, a filter for inspection for adsorbing the particulates in the sample gas, and a pressure sensor for measuring the pressure difference in front of and after the filter for inspection.
