error proof mounting system for exhaust treatment device

摘要

patent summary: "error-proof mounting system for exhaust treatment device". The present invention relates to an exhaust treatment system comprising an exhaust treatment device for treating exhaust emitted from an internal combustion engine. The exhaust treatment system includes a housing adapted to support the first and second spaced portions of the exhaust treatment system. the emission treatment device interconnects the first and second portions and is in the exhaust receiving from the first portion and provides a treated exhaust to the second portion. a first support is fixed to the frame and includes one of a protrusion and a receptacle. a second bracket is adapted to be attached to the emission treatment device and includes the other of a protrusion and the receptacle. the protrusion is positioned within the receptacle when the emission treatment device is properly positioned. the protrusion interferes with one of the second bracket and the emission treatment device to prevent mounting when the emission treatment device is improperly positioned.
