Liquid e.g. diesel fuel, vaporizer for being fixed to structure i.e. particle filter, of exhaust line of diesel engine motor vehicle, has envelope connection unit with indexing unit to block envelope relative to base at position around axis

摘要

The vaporizer has an annular base connection unit for connecting an annular base (17) to a structure i.e. particle filter, of an exhaust line. A hollow envelope connection unit (33) connects a hollow envelope (21) to the base. The base connection unit has an indexing unit to block the base with respect to the structure at a preset angular position around a determined main axis (X). The unit (33) has another indexing unit to block the envelope with respect to the base at another preset angular position around the axis, where the latter indexing unit includes a thread (77) and a tapping (75).
