The purpose of this device is to reduce the fuel consumption of heavy trucks by improving airflow past trailer axles. Rather than restrict airflow to the side of the vehicle, diffusers streamline its aerodynamic profile and allow air to flow smoothly beneath. A series of panels mounted to each axle of a truck and trailer forms a substantially continuous surface from the front to the rear axle, promoting laminar flow to the aft of the vehicle, minimizing the effect of suction drag.
