## Abstract

Embodiments of the present disclosure describe a snow vehicle, comprising an engine mounted on a frame, a drive track, a drive train operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track, and exhaust system. The exhaust system is positioned within an interior of the frame of the vehicle.

## Claims

### Claim 1

A snow vehicle, comprising:
an engine, mounted on a frame comprising a tube chassis;
a drive track;
a drive train, operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track;
an exhaust system comprising a muffler in contact with the exhaust system connected to the engine and positioned within an interior of the tube chassis;
wherein the drive train includes a continuously variable transmission (CVT) positioned within a CVT housing.

### Claim 2 (depends on 1)

The snow vehicle of claim 1, wherein the CVT housing includes an air handling system for cooling the CVT.

### Claim 3 (depends on 2)

The snow vehicle of claim 2, wherein the air handling system comprises an intake and an exit port.

### Claim 4 (depends on 1)

The snow vehicle of claim 1, further comprising an air intake system, in contact with the engine.

### Claim 5 (depends on 4)

The snow vehicle of claim 4, wherein the air intake system is rear facing.

### Claim 6 (depends on 4)

The snow vehicle of claim 4, wherein the air intake system is positioned on top of the engine and in contact with the frame.

### Claim 7 (depends on 1)

The snow vehicle of claim 1, further comprising an engine cooling system.

### Claim 8 (depends on 7)

The snow vehicle of claim 7, further comprising a heat exchanger positioned above the drive track.

### Claim 9 (depends on 7)

The snow vehicle of claim 7, further comprising a shroud, positioned above the engine cooling system.

### Claim 10

A snow vehicle, comprising:
an engine, mounted on a frame;
a drive track;
a drive train, operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track; and
an engine air intake system, positioned above the engine and integrated with the frame;
wherein the air intake system encloses a portion of the frame.

### Claim 11 (depends on 10)

The snow vehicle of claim 10, further comprising a muffler in contact with the exhaust system.

### Claim 12 (depends on 11)

The snow vehicle of claim 11, wherein the muffler is positioned within an interior of the frame.

### Claim 13 (depends on 10)

The snow vehicle of claim 10, further comprising an exhaust system positioned within an interior of the frame.

### Claim 14 (depends on 10)

The snow vehicle of claim 10, wherein the air intake system is rear facing.

### Claim 15 (depends on 10)

The snow vehicle of claim 10, wherein the air intake system is positioned on top of the engine.

### Claim 16 (depends on 10)

The snow vehicle of claim 10, further comprising an engine cooling system.

### Claim 17 (depends on 16)

The snow vehicle of claim 16, further comprising a heat exchanger positioned above the drive track.

### Claim 18

A snow vehicle, comprising:
an engine, mounted on a frame comprising a tube chassis;
a drive track;
a drive train, operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track;
an engine air intake system, positioned above the engine, wherein the tube chassis extends through the air intake system; and
an exhaust system, positioned within an interior of the tube chassis;
wherein the engine air intake system includes a rearwardly facing air intake port; and
wherein the drive train includes a CVT.

### Claim 19 (depends on 18)

The snow vehicle of claim 18, wherein the tube chassis extends through the engine air intake system.
