  • Mounting device for an injector in an exhaust system of an internal combustion engine
    Patent number: 8261537
    Abstract: A mounting device for an injector in an exhaust system of an internal combustion engine; the mounting device is provided with a tubular support body, which is made of a thermally conductive material, houses the injector therein, and is adapted to be coupled to a connection tube laterally extending outwards from an exhaust conduit of the exhaust system at a lower end thereof; an upper portion of the support body is thermally coupled to an upper portion of a nose of the injector so that a high thermal exchange occurs by conduction between the upper portion of the nose of the injector and the upper portion of the support body; and a lower portion of the support body is thermally insulated from a lower portion of the nose of the injector so that a reduced thermal exchange occurs by conduction between the upper portion of the nose of the injector and the upper portion of the support body.
