A vehicle having one or more small vehicle-mounted electricity generating wind turbines located within an area of wind recirculation. The electricity generated is used to recharge vehicle batteries, partially power an auxiliary electric propulsion motor, or supply vehicle parasitic loads.

A fluid inlet grille () with aerodynamic grille bars () formed by leading grille bars () and trailing grille bars () separated by gaps (). Each of the novel aerodynamic grille bars of the fluid inlet grille is constructed in such a manner that along a majority of its length its transverse cross section has a maximum width greater than its trailing edge width.

The invention is a splash and spray suppressor for a wheeled motor vehicle, especially for trucks. The splash and spray suppressor includes a wheel panel nested within the fender. Apertures in the wheel panel allow water droplets to flow into the gap between the wheel panel and the fender. Droplets then flow within the gap toward an opening from where the droplets are drained from the splash and spray suppressor.

A vehicle cooling system for a mobile vehicle consists of three essential parts. These are a compressed air reservoir, a heat exchanger and a duct connecting the reservoir and the heat exchanger. On demand, the compressed air will be released to the duct and will expand (as the end connected to the reservoir is expected to be lower in cross-sectional area compared to the end connected to the face of the heat exchanger). This expansion will lead to the reduction in air temperature. This helps in increasing the heat rejection capacity of the cooling system. The colder air passes through the heat exchanger and carries away the heat. This air exits from the other end of the heat exchanger into the environment. A fan is optional to operate behind the heat exchanger to help draw the air though it. The compressed air may originate in the vehicle air system for operating air brakes found on medium and heavy-duty trucks or the compressed air may originate from a separate air compressor. The system may be located in various locations on the vehicle due to the lack of reliance on ram air caused from vehicle movement.

Heating, ventilation and air conditioning systems for busses achieve improved air distribution by the use of ducts to distribute the air throughout the passenger compartment. The ducts have a varying cross sectional area so that the impedance to air flow appears constant at all points along the duct. The quantity of air distributed from each of a plurality of vents is substantially even is effectively equalized.

A tractor-trailer system uses aerodynamic principles to use crosswind to its advantage. The system has a curvilinear duct by having a attaching a convex body on the trailer front and a concave body on the back of the cab. When a cross wind enters the gap, it creates a negative pressure (compare to ambient) on the convex surface (trailer front) and a positive pressure on concave surface (back of the cab). Both of these pressures will help reduce the drag. Further having the crosswind flow smoothly can lead to less turbulence intensity in the gap, which can help in improving handling qualities of the system. There is a similar situation both for drag as well as handling qualities can be given for the air traveling in vertical direction (even at zero cross wind).
