Abstract
A vehicle including an airflow system defining an air passageway to facilitate airflow to or from an engine component. The airflow system includes a noise control mechanism, such as an attenuator or a tortuous portion of the air passageway, for reducing or otherwise controlling noise associated with the engine component. Positioning and orientation of various inlets provides additional noise reduction for passengers of the vehicle.
Claims23
A vehicle, comprising:
- a vehicle shell including a vehicle cabin and a vehicle frame, the vehicle shell defining a passenger compartment and an engine compartment, wherein a first pillar of the vehicle shell includes at least one of a vertically extending component of the vehicle frame and a vertically extending portion of the vehicle cabin;
- a first engine component positioned at least partially within the engine compartment;
- two or more ground engaging members operably coupled with the first engine component;
- and
- an airflow system in fluidic communication with the first engine component, wherein the airflow system includes:
- a primary duct defining at least a portion of an air passageway through which air flows towards the first engine component;
- a first duct coupled with the primary duct and defining a portion of the air passageway;
- a first port fluidically connected with the first duct, wherein the first port is positioned outboard of the first pillar, and wherein the first duct extends from the first port toward the primary duct;
- and
- a noise control mechanism extending from the primary duct.

A side-by-side recreational off-highway vehicle having two front wheels and two rear wheels, the vehicle comprising:
- a chassis including:
- a front portion operatively coupled to the front wheels;
- a rear portion operatively coupled to the rear wheels;
- and
- a middle portion defining a vehicle cabin including one or more seats, the middle portion positioned between the front and rear portions of the chassis;
- an engine positioned in the rear portion of the chassis;
- a continuous variable transmission (“CVT”) operably connected to the engine, the CVT comprising a housing (“CVT housing”) including an air inlet (“CVT air inlet”);
- an air intake port positioned outboard of the vehicle cabin, the air intake port being in fluid communication with the CVT air inlet;
- and
- a noise control mechanism in fluid communication with the air intake port and the CVT air inlet, wherein the noise control mechanism comprises at least one attenuator or at least one resonator, and wherein the noise control mechanism is positioned downstream of the air intake port and upstream of the CVT air inlet.
