  • Particulate matter detection system
    Patent number: 11300532
    Abstract: A particulate matter detection system detects a particulate matter in exhaust gas. The particulate matter detection system includes: a particulate matter detection sensor in which at least one detection portion is provided, the at least one detection portion including at least one pair of multiple electrodes and a deposition surface which is interposed between the pair of electrodes and which the particulate matter is deposited on; a capacitor connected to the at least one detection portion in series; a power supply configured to apply a direct voltage to a series body including the at least one detection portion and the capacitor; and a voltage measurement portion configured to measure a voltage of the capacitor.
    Type: Grant

  • Porous honeycomb filter
    Patent number: 10870077
    Abstract: Provided is a porous honeycomb filter comprising a porous first cell wall that permits exhaust gas to permeate, a second cell wall that permits exhaust gas to permeate than the first cell wall, and a cell that is surrounded by the first cell wall and the second cell wall to form an extending gas flow passage. The second cell wall has a smaller porosity than the first cell wall.
