연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

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.

The exhaust treatment system of claim 1, wherein the emissions treatment device includes a diesel particulate filter. 3. The exhaust treatment system of claim 1, further including another protrusion fixed to the first bracket, the another protrusion interfering with the emissions treatment device when the upstream and downstream orientation of the emissions treatment device is reversed. 4. The exhaust treatment system of claim 3, wherein the protrusion and the another protrusion each include seats defining a cradle to temporarily support the emissions treatment device during installation. 5. The exhaust treatment system of claim 1, wherein the first bracket is elongated, coupled to the frame at opposite ends and extends parallel to the emissions treatment device. 6. The exhaust treatment system of claim 5, wherein the protrusion transversely extends relative to a direction of exhaust flow. 7. The exhaust treatment system of claim 6, wherein the receptacle includes a circumferentially extending slot. 8. The exhaust treatment system of claim 7, wherein the protrusion includes a planar blade sized to be received within the slot. 9. The exhaust treatment system of claim 8, wherein the frame includes first and second radially extending flanges adapted to be fixed to the first and second portions, respectively. 10. An exhaust treatment system comprising: first, second and third emissions treatment devices positioned in series fluid communication, the second emissions treatment device being removable from between the first and third emissions treatment devices;a first bracket coupled to one of the first and third emissions treatment devices and including a protrusion; anda second bracket permanently fixed to the second emissions treatment device and including a receptacle, wherein the protrusion is positioned within the receptacle when the second emissions treatment device is properly positioned and wherein the protrusion interferes with one of the second bracket and the second emissions treatment device to preclude assembly when the second emissions treatment device is improperly positioned. 11. The exhaust treatment system of claim 10, further including another protrusion fixed to the first bracket, the another protrusion interfering with the second emissions treatment device when the upstream and downstream orientation of the second emissions treatment device is reversed. 12. The exhaust treatment system of claim 11, wherein the protrusion and the another protrusion each include seats defining a cradle to temporarily support the second emissions treatment device during installation. 13. The exhaust treatment system of claim 11, wherein the protrusion transversely extends relative to a direction of exhaust flow. 14.
