Abstract
The purpose of this device is to reduce the fuel consumption of heavy trucks by improving airflow to the rear of the trailer and reduce suction drag. Rather than restrict airflow to the side of the vehicle, diffusers streamline its aerodynamic profile and allow air to flow smoothly beneath. A large airfoil extending forward from the ICC bumper promotes stable airflow to the aft of the vehicle, reducing turbulence by keeping airflow at a consistent height. Fairings fitted to other structures such as the bumper uprights further shape and stabilize airflow.
Claims25
A bumper diffuser for a freight vehicle having a rear impact guard, wherein the bumper diffuser comprises:
- an airfoil having
- an upper surface defining an upper airflow volume above said rear impact guard
- a lower surface defining a lower airflow volume below said rear impact guard,
- a leading edge defining a foremost extent of the airfoil,
- wherein the airfoil forms a forward extension of said rear impact guard,
- wherein the airfoil is generally horizontal when used with said freight vehicle.
