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.
