Abstract

A modular snorkel system for an off-road vehicle has a hollow main body that normally is hidden from view behind a fender of the vehicle. The main body terminates at its upper end in an intake mount that projects upwardly from an end of the forward cowl of the vehicle. The other end of the main body is coupled to an end of an air tube that is configured to be routed through the engine bay of the vehicle, again normally hidden from view. The other end of the air tube is coupled through an elbow to the air filter housing of the vehicle. Various intake modules such as a low intake module, a high intake module, an in-line filter module, and others can be mounted to the intake mount of the main body to accommodate different hostile off-road conditions such as water fording and operation in deserts.

First claim

What is claimed is:

1. A snorkel for a vehicle having a front outer fender, a front inner fender, an engine compartment, and an air box within the engine compartment through which intake air is drawn, the snorkel comprising:
an air tube defining an internal passageway and being in fluid communication at one end with the air box with the air tube extending rearwardly within the engine compartment to an opposite end;
a main body defining an internal passageway and being in fluid communication at an outlet end with the opposite end of the air tube, the main body being configured to extend upwardly between the outer front fender and the inner front fender of the vehicle to an upper end so that a major portion of the main body is substantially hidden from view; and
an intake mount coupled to the upper end of the main body to which intake modules can be selectively attached, the intake mount being exposed above the front outer fender of the vehicle.

2. A snorkel as claimed in claim 1 further comprising an intake module attached to the intake mount.

3. A snorkel as claimed in claim 1 wherein the air tube is made of metal.

4. A snorkel as claimed in claim 1 wherein the main body is configured to form a sump at a lower extent, the sump being located below the inlet end of the main body for collecting water that may be injected into the main body and preventing the water from entering the air tube.

5. A snorkel as claimed in claim 1 further comprising a mounting flange on the intake mount for receiving intake modules.

6. A snorkel as claimed in claim 2 wherein the intake module comprises a low intake module.

7. A snorkel as claimed in claim 2 wherein the intake module comprises a high intake module.

8. A snorkel as claimed in claim 2 further comprising a valve coupled to the sump to allow water to be drained from the sump selectively by a user.

9. A snorkel as claimed in claim 6 wherein the low intake module is configured to direct air first upwardly and then downwardly into the intake mount.

10. A snorkel as claimed in claim 7 wherein the high intake module terminates in an inlet substantially at the level of the top of the vehicle.

11. A snorkel as claimed in claim 10 wherein the inlet is a ram scoop.

12. A snorkel as claimed in claim 3 further comprising a heat shield attached to the air tube and being located to shield the air tube from heat of an adjacent engine.

13. A snorkel as claimed in claim 12 wherein the heat shield is located adjacent an exhaust manifold of the engine.

14. A snorkel as claimed in claim 4 further comprising a drain tube coupled to the sump of the main body for draining water collected in the sump.
