- 4. A motor vehicle as claimed in claim 2 wherein said air exhaust duct comprises a right duct portion operatively connected to a left duct portion.
- 5. An air duct system for a power unit including an engine having a crankshaft and a fan operatively connected to said crankshaft and a radiator, said air duct system interposed between the radiator and the engine and comprising an air exhaust duct for guiding warm air away from the engine without coming into contact therewith, the warm air emanating from the vicinity of the radiator, said air exhaust duct adapted to enclosure at least a portion of an engine exhaust manifold within said duct.
- 6. The air duct system duct according to claim 5, further including a fan shroud formed integrally with the air exhaust duct.
- 7. The air duct system according to claim 5 wherein said air exhaust duct has at least one outlet port facing radially outwardly of a horizontal plane.
- 8. The air duct system according to claim 5 wherein said air exhaust duct comprises a right duct portion operatively connected to a left duct portion.
- 9. The air duct system according to claim 5 further including an engine enclosure.
- 10. A motor vehicle as claimed in claim 1 wherein the air exhaust duct at least partially surrounds the engine.
- 11. The air duct system according to claim 5 wherein said air exhaust duct is adapted to at least partially surround the engine.
- 12. A motor vehicle as claimed in claim 1 wherein said air exhaust duct extends between a rear portion of the engine and a front wall of an engine enclosure.
- 13. A motor vehicle as claimed in claim 12 wherein said air exhaust duct communicates with apertures formed in said front wall of said engine enclosure.
- 14. A motor vehicle as claimed in claim 12 wherein said air exhaust duct is operatively connected to a duct portion associated with said front wall portion of said engine enclosure.
- 15. The air duct system according to claim 5 wherein said air exhaust duct is adapted to extend between a rear portion of the engine and a front wall of an engine enclosure.
- 16. The air duct system according to claim 15 wherein said air exhaust duct is adapted to communicate with apertures formed in the front wall of said engine enclosure.
- 17. The air duct system according to claim 15 wherein said air exhaust duct is operatively connected to a duct portion adapted to be associated with a front wall portion of an engine
- 18. A motor vehicle as claimed in claim 1 wherein at least a portion of an engine exhaust manifold is enclosed within said air exhaust duct.
- 19. A an air duct system for a power unit including an engine having a crankshaft and a fan operatively connected to said crankshaft and a radiator, said air duct system interposed between the radiator and the engine and comprising an air exhaust duct for guiding warm air away from the engine without coming in contact therewith, the warm air emanating from the vicinity of the radiator, said air exhaust duct adapted to enclosure an engine exhaust muffler within said duct.
- 20. The air duct system duct according to claim 19, further including a fan shroud formed integrally with the air exhaust duct.
- 21. The air duct system according to claim 19 wherein said air exhaust duct has at least one outlet port facing radially outwardly of a horizontal plane.
- 22. The air duct system according to claim 19 wherein said air exhaust duct comprises a right duct portion operatively connected to a left duct portion.
- 23. The air duct system according to claim 19 further including an engine enclosure.
- 24. The air duct system according to claim 19 wherein said air exhaust duct is adapted to at least partially surround the engine.
- 25. The air duct system according to claim 19 wherein said air exhaust duct is adapted to extend between a rear portion of the engine and a front wall of an engine enclosure.
- 26. The air duct system according to claim 25 wherein said air exhaust duct is adapted to communicate with apertures formed in the front wall of said engine enclosure.
- 27. The air duct system according to claim 25 wherein said air exhaust duct is operatively connected to a duct portion adapted to be associated with a front wall portion of an engine enclosure.
