摘要： A particulate matter concentration measuring apparatus is configured to measure a concentration of particulate matter in exhaust gas flowing through an exhaust line of a diesel engine. The apparatus includes an exhaust gas extraction line diverging from the exhaust line and having a flow passage cross-sectional area smaller than a flow passage cross-sectional area of the exhaust line. A particulate matter detection filter has a cell wall and is provided in the exhaust gas extraction line. A flow velocity of the exhaust gas passing through the cell wall is more than or equal to approximately 0.02 m/s and less than or equal to approximately 2.0 m/s. A differential pressure sensing part is configured to sense a differential pressure generated between an inlet and an outlet of the particulate matter detection filter.

The detection filter is installed in an exhaust passage connected to an internal combustion engine and is configured to detect particulate matter contained in an exhaust gas passing through the exhaust passage. The differential pressure detecting unit is configured to detect a pressure difference between an upstream side and a downstream side of the detection filter. The on-off valve is installed on the upstream side of the detection filter in the exhaust passage and is configured to control a flow of the exhaust gas toward the detection filter. The valve control unit is configured to control the on-off valve to be opened and closed.
