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.

摘要： A particulate matter concentration measuring apparatus configured to measure concentration of particulate matter in exhaust gas passing through an exhaust line includes an exhaust gas collecting line branched from the exhaust line, a particulate matter detection filter provided in the exhaust gas collecting line, a differential pressure sensor configured to sense differential pressure between an inlet and an outlet of the particulate matter detection filter, a passage wall disposed so that the exhaust gas flows to a downstream side of the particulate matter detection filter, an inlet side passage through which the exhaust gas flows into the particulate matter detection filter in the passage wall, and an outlet side passage through which the exhaust gas flows out from the particulate matter detection filter. The outlet side passage has an outlet side cross-sectional area approximately 1.0 times or more larger than an inlet side cross-sectional area of the inlet side passage.

摘要： A sensor for an exhaust gas purifying apparatus includes an examining filter and a holding member. The examining filter is provided in a secondary exhaust line diverging from a primary exhaust line of an internal combustion engine. The holding member holds the examining filter on the secondary exhaust line. The holding member holds an approximately 10% to approximately 50% part by area of a peripheral portion of the examining filter so as to cover the part from a peripheral side of the examining filter.

摘要： A particulate matter concentration measuring apparatus configured to measure a particulate matter concentration in exhaust gas includes an exhaust gas extraction line that is branched from an exhaust line and has a flow passage cross-sectional area smaller than that of the exhaust line, a particulate matter detection filter provided in the exhaust gas extraction line and configured to catch particulate matter, a heating unit configured to heat the caught particulate matter, and a differential pressure detection unit configured to detect a differential pressure generated between an inlet and an outlet of the particulate matter detection filter. The heating unit is configured to apply about 50% or more of a calorific value for heating the particulate matter to an area making up about 30% of the particulate matter detection filter on an upstream side of an exhaust gas flow.
