Mounting device for an injector in an exhaust system of an internal combustion engine

Abstract of EP 2105592 (A1) A mounting device (13) for an injector (12) in an exhaust system (1) of an internal combustion engine (2); the mounting device is provided with a tubular support body (14), which is made of a thermally conductive material, houses the injector (12) therein, and is adapted to be coupled to a connection tube (15) laterally extending outwards from an exhaust conduit (3) of the exhaust system (1) at a lower end thereof; an upper portion of the support body (14) is thermally coupled to an upper portion of a nose (18) of the injector (12) so that a high thermal exchange occurs by conduction between the upper portion of the nose (18) of the injector (12) and the upper portion of the support body (14); and a lower portion of the support body (14) is thermally insulated from a lower portion of the nose (18) of the injector (12) so that a reduced thermal exchange occurs by conduction between the upper portion of the nose (18) of the injector (12) and the upper portion of the support body (14).
