Ballast weights are positioned to then deflect the air out of the enclosure through the opening that is spaced from the grille.
Claims18
A powered vehicle, comprising:
- a power source for powering the vehicle;
- a cooling system for cooling the power source, and having an outlet through which outlet air exits;
- an exhaust muffler coupled with the power source, and having an exterior surface;
- an enclosure within which is contained the power source, cooling system and muffler;
- a grille forming a portion of the enclosure for allowing ambient air to pass into and out of the enclosure;
- a deflector positioned within the enclosure for channeling at least a portion of the outlet air onto the exterior surface of the muffler, a portion of said deflector being positioned between the muffler and the grille for blocking the air that has passed over the exterior surface of the muffler from flowing, through the grille;
- the enclosure defining an opening spaced from the grille, and through which the air that has passed over the muffler exits the enclosure;
- and
- at least one ballast weight positioned adjacent the muffler for deflecting air that has passed over the muffler through the opening in a generally horizontal direction.
