Abstract:
1. A mounting device connecting an injector onto an exhaust system of an internal combustion engine comprising a thermally conductive tubular support body in which the injector is retained, the mounting device herein being adapted to be coupled to a connection tube extending outwardly from a lower end of an exhaust conduit of the exhaust system; an upper portion of the support body thermally coupled to an upper portion of a nose of the injector so that a high heat exchange by conduction occurs between the upper portion of the nose and the upper portion of the support body; a lower portion of the support body thermally insulated from a lower portion of the nose so that a reduced heat exchange occurs by conduction between the lower portion of the nose and the lower portion of the support body; a tubular conductive element comprised of a thermally conductive material, arranged within the upper portion of the support body to maintain the upper portion of the nose thermally coupled to the support body; a tubular insulating element, made of a thermally insulating material, arranged within the lower portion of the support body to maintain the lower portion of the nose thermally insulated from the support body; and a first insulating ring comprised of a thermally insulating material interposed between the tubular insulating element and the tubular conductive element.
