Snowmobile air box assembly
View Patent ↗The present invention is directed to an air box assembly for a snowmobile. The air box assembly is capable of being positioned frontward of the snowmobile engine, relative to a front end of the snowmobile. In this position, throttle noise being dampened by the air box assembly is further removed from an operator of the snowmobile sitting in an operator position on the snowmobile.
1. A snowmobile, comprising:
an engine having at least two throttle body assemblies with at least two inlet tubes; and
an air silencer positioned in front of the engine relative to a front end of the snowmobile, the air silencer having an air inlet/outlet port in fluid communication with the throttle body assemblies; and
a flexible tube having a first end and a second end, the first end having an inlet aperture secured to the air inlet/outlet port and the second end secured to the throttle body assemblies, the second end having two or more outlet apertures receiving the at least two inlet tubes of the throttle body assemblies.
2. The snowmobile of claim 1 , further comprising an air source in fluid communication with a first portion of the air silencer.
3. The snowmobile of claim 1 wherein the air silencer is configured with multiple internal chambers, the chambers being capable of dampening throttle noise generated by the throttle body assemblies.
4. The snowmobile of claim 1 wherein the air silencer includes a top wall, a bottom wall, and a rear wall, the top wall having an air iniet, the bottom wall securable to a chassis of the snowmobile, and the rear wall having the air inlet/outlet port that is in fluid communication with the throttle body assemblies.
5. The snowmobile of claim 4 , wherein the bottom wall is operable as a nose cone for the snowmobile.
6. The snowmobile of claim 4 , wherein the bottom wall is operable as a bumper for the snowmobile.
