  • Apparatus and method for mat protection of non-thermal plasma reactor
    Patent number: 7078000
    Abstract: A non-thermal plasma reactor is provided. The non-thermal plasma reactor includes a plasma-generating substrate, a housing and a mat. The plasma-generating substrate has one or more flow paths for an exhaust gas. The housing has an inlet and an outlet. The mat retains the plasma-generating substrate in the housing such that the one or more flow paths are in fluid communication with the inlet and the outlet. A voltage is supplied to the plasma-generating substrate to generate a plasma field. An electrically insulating layer is disposed between the plasma-generating substrate and the housing for preventing an arc of electricity from the plasma-generating substrate and/or the voltage to the housing.
    Type: Grant
    Filed: June 14, 2001
    Date of Patent: July 18, 2006
    Assignee: Delphi Technologies, Inc.
    Inventors: Michael R. Foster, Robert X. Li, David E. Nelson
  • Apparatus and method for retention of non-thermal plasma reactor
    Patent number: 6893617
    Abstract: A non-thermal plasma reactor is provided. The reactor includes a plasma-generating substrate, a housing, a voltage supplied to the plasma-generating substrate, and a retention material. The plasma-generating substrate has one or more flow paths for an exhaust gas. The plasma-generating substrate includes at least one weak area and at least one strong area. The housing has an inlet opening and an outlet opening. The voltage is supplied to the plasma-generating substrate for generating a plasma field. The retention material retains the plasma-generating substrate in the housing such that the one or more flow paths are in fluid communication with the inlet opening and the outlet opening. The retention material is configured to provide a higher retention force to the at least one strong area and a lower retention force to the at least one weak area.
