Improving Aerodynamics Of 18 Wheeler Roof Fairing

The truck tractor aerodynamics include an number of modifications such as roof fairings side extender and side tank fairings aerodynamic front bumper and mirrors.

Improving aerodynamics of 18 wheeler roof fairing. Base models that use a mid roof design lose about 10 fuel economy when hauling dry vans or reefers due to the drag on the exposed portion of the. Aerodynamic drag works against the vehicle s propulsion at any speed above 0 mph or kmph. This is because heavy trucks burn a lot of diesel as they push up against air resistance. The trailer aerodynamic options include side skirts or fairings wheel covers and boat tails at the back of the trailer.

The initial aerodynamics of a vehicle are established by the truck manufacturer with their base model. Improving the aerodynamics of tractor trailers has become a big issue in recent years. When an 18 wheeler travels on the highway more than 50 of its fuel use goes toward reducing aerodynamic drag. However older vehicles are modifiable manufacturers produce aftermarket accessories that improve 18 wheeler aerodynamics.

Full chassis fairings with rubber skirts from the quarter fender to the front of the tandem axle with rubber closeouts under the sides of the cab and sleeper. Such as antennas bumper valances roof fairings and chassis configurations. Equipping older trucks with cab and roof extenders also known as fairings can help to improve aerodynamics by preventing air from moving into the space between the cab and the trailer. Peterbilt s model 579 epiq package offers a complete aerodynamic configuration including 18 in.

Modern sleeper cabs are designed to help improve aerodynamics but older trucks with their blocky frames are less than aerodynamic. Aerodynamic 18 wheelers will save.
