Abstract
A rear covering part fastened to a tail pipe orifice for a motor vehicle exhaust system. The rear covering part includes a completely bordered passage opening through which the tail pipe orifice penetrates. The rear covering part avoids damage to the exhaust system in the event of an accident-caused deformation. The passage cross-section of the tail pipe orifice (7, 7′), over its entire length (LG), is larger than the exterior cross-section (W3) of the tail pipe (3) of the exhaust system.
Claims20
A rear covering part having a tail pipe orifice fastened thereto for an exhaust system of a motor vehicle, having a bordered passage opening for the tail pipe orifice, the tail pipe orifice comprising:
- an air inlet section including an inlet opening which communicates with a tail pipe of the exhaust system and extends over the tail pipe, said inlet opening situated at a radial distance from said tail pipe,
- an outlet opening situated downstream with respect to the inlet opening,
- a transition section situated between the inlet opening and the outlet opening and tapering in its cross-section, and
- an interior cross-section of the inlet opening which is larger than the exterior cross-section of the tail pipe, and
- wherein a passage cross-section along an entire length of the tail pipe orifice is larger than an exterior cross-section of the tail pipe of the exhaust system.
A tail pipe orifice structure for a motor vehicle exhaust system, comprising:
- an air inlet section including an inlet opening with an interior cross-section larger than an exterior cross-section of a tail pipe of said motor vehicle;
- an outlet opening positioned downstream from said inlet opening;
- a transition section situated between said inlet opening and said outlet opening and having a tapered cross-section;
- wherein a passage cross-section along an entire length of the tail pipe orifice structure is larger than an exterior cross-section of the tail pipe.
