POKA-YOKE MOUNTING SYSTEM FOR AN EXHAUST TREATMENT DEVICE

摘要

An exhaust treatment system includes an emissions treatment device for treating exhaust emitted from an internal combustion engine. The exhaust treatment system includes a frame adapted to support first and second spaced apart portions of the exhaust treatment system. The emissions treatment device interconnects the first and second portions and is in receipt of exhaust from the first portion and provides treated exhaust to the second portion. A first bracket is fixed to the frame and includes one of a protrusion and a receptacle. A second bracket is adapted to be fixed to the emissions treatment device and includes the other of the protrusion and the receptacle. The protrusion is positioned within the receptacle when the emissions treatment device is properly positioned. The protrusion interferes with one of the second bracket and the emissions treatment device to preclude assembly when the emissions treatment device is improperly positioned.
