Poka-Yoke Mounting System For An Exhaust Treatment Device

摘要

An exhaust treatment system includes first and second exhaust conduits positioned on opposite ends of an exhaust treatment device. The exhaust treatment device includes a housing having a first outer diameter at a first end and a different second outer diameter at a second end. A clamp includes an inner surface engaging both the first exhaust conduit and the exhaust treatment device when the exhaust treatment device is positioned with its first end adjacent to the first exhaust conduit. The inner surface of the clamp is spaced apart from one of the housing and the exhaust treatment device when the second end of the exhaust treatment device is adjacent the first exhaust conduit.

主权项

1. An exhaust treatment system including first and second spaced apart portions in receipt of exhaust emitted from an internal combustion engine, the exhaust treatment system comprising:
an exhaust treatment device including a housing having a first outer diameter at an open first end of the exhaust treatment device, the housing having a second outer diameter different than the first diameter at an open second end of the exhaust treatment device; a first clamp adapted to couple the exhaust treatment device to the first portion, the first clamp including a stepped inner diameter such that the first clamp engages both the first portion and the exhaust treatment device when the first end of the exhaust treatment device is positioned adjacent to the first portion; and a second clamp coupling the exhaust treatment device to the second portion, wherein the second end of the exhaust treatment device interferes with the first clamp to preclude coupling the first portion to the exhaust treatment device when the second end of the exhaust treatment device is positioned adjacent to the first portion.
