Abstract: Drag reducing systems for tractor-trailer combination vehicles are provided. In one aspect, a drag reducing assembly generally includes a stowable mud flap rotatably coupled to a mounting bracket and a linkage. The linkage is configured to transition the mud flap between a first, deployed position, to a second, stowed position. The mud flap is generally positioned adjacent a wheel and tire of the vehicle, downstream of airflow. In the first position, the mud flap may be deployed at an angle of about 90° to the ground. In the second position, the mud flap may be stowed at an angle of about 90° from the first position.

Abstract: A diffuser is configured for use on a vehicle having an engine and an exhaust pipe. The diffuser includes a conduit with a first end configured to receive exhaust gases from the engine. A diffusion fitting is coupled to a second end of the conduit to receive exhaust gases discharged from the conduit. The diffusion fitting has an outer wall that includes a curved surface. The curved surface is configured to guide the exhaust gases discharged from the conduit about an axis so that exhaust gases exit a first side of the diffusion fitting rotating about the axis.

Abstract: Aerodynamically configured trailers are provided with a downwardly slanted top surface section positioned at the rear of the trailer. In use, the rearward cant or slope reduces the low-pressure region that trails the end of the trailer, thereby reducing pressure drag. Aerodynamically configured trailers are also provided that maintain standard cargo capacity in a first configuration, and can convert to a reduced cargo capacity in a second configuration. In some examples, a rear roll-up door of one or more configurations is provided to facilitate loading/unloading, etc.

Abstract: Systems and methods are disclosed that utilize exhausted gases from an internal combustion engine (e.g., piston engine, rotary engine, turbine engine, etc.) of a vehicle for reducing the aerodynamic drag thereon. In some disclosed examples, the systems and methods utilize a generated gas flow from, for example, electric fans, engine driven or pneumatically/hydraulically driven pumps, etc., for reducing aerodynamic drag. The generated gas flows in several disclosed examples are directed in a generally opposing direction of (i.e., against) prevailing cross winds.
