Abstract

An exhaust system for a vehicle including a deep snow exhaust outlet defined by a driveline structural member of the vehicle. If the vehicle includes a turbo charger and an exhaust silencer, the turbocharger and the exhaust silencer are coupled together without exhaust piping therebetween.

Claims (28)

1. An exhaust system for a vehicle comprising:

a turbocharger assembly; and

an exhaust silencer, the turbocharger assembly and the exhaust silencer are coupled together without exhaust piping therebetween;

wherein the turbocharger assembly is fully supported by the exhaust silencer.

2. The exhaust system of claim 1 , wherein the turbocharger assembly includes a turbine housing with a turbocharger turbine therein, the turbine housing is connected to the silencer without intermediary exhaust piping therebetween.

3. The exhaust system of claim 1 , wherein the turbocharger assembly and the exhaust silencer are directly coupled together.

4. The exhaust system of claim 1 , wherein the vehicle includes at least one snow ski.

5. The exhaust system of claim 1 , wherein engine exhaust exiting the turbocharger assembly flows directly into the exhaust silencer without flowing through intermediary piping.

6. The exhaust system of claim 1 , further comprising an adaptor flange connecting the turbocharger assembly and the exhaust silencer together.

7. The exhaust system of claim 6 , wherein the adaptor flange is bolted to a turbine housing of the turbocharger assembly and to the exhaust silencer.

8. The exhaust system of claim 1 , further comprising a v-band clamp directly connecting the turbocharger assembly and the exhaust silencer together.

9. The exhaust system of claim 8 , wherein the v-band clamp is part of the exhaust silencer and a turbine housing of the turbocharger assembly is clamped to the v-band clamp.

10. The exhaust system of claim 8 , wherein the v-band clamp is part of a turbine housing of the turbocharger assembly and the exhaust silencer is clamped to the v-band clamp.

11. The exhaust system of claim 1 , wherein the vehicle is a snowmobile, the exhaust system further comprising a deep snow exhaust outlet defined by a driveline structural member of the snowmobile, a belt drive or chain drive assembly for propelling the snowmobile is mounted to the driveline structural member.

12. The exhaust system of claim 11 , further comprising an exhaust conduit extending from the exhaust silencer to the deep snow exhaust outlet.

13. The exhaust system of claim 11 , wherein:

the deep snow exhaust outlet is entirely defined by the driveline structural member; and

the driveline structural member is a single cast plate, a stamped plate, or a forged plate entirely defining the deep snow exhaust outlet.

14. An exhaust system for a vehicle having at least one snow ski comprising:

a deep snow exhaust outlet defined by a driveline structural member of the vehicle;

a belt drive or chain drive assembly for propelling the vehicle is mounted to the driveline structural member;

a turbocharger assembly; and

an exhaust silencer coupled to the turbocharger assembly without intermediary exhaust piping therebetween;

wherein the turbocharger assembly is fully supported by the exhaust silencer.

15. The exhaust system of claim 14 , wherein the driveline structural member is a single cast plate, a stamped plate, or a forged plate entirely defining the deep snow exhaust outlet.

16. The exhaust system of claim 14 , wherein the deep snow exhaust outlet is inside a belt of the belt drive assembly.

17. The exhaust system of claim 14 , wherein the deep snow exhaust outlet is forward of a foot-well of the vehicle.

18. The exhaust system of claim 14 , further comprising an exhaust conduit extending from the exhaust silencer to the deep snow exhaust outlet.
