Bachelor thesis of this research is the subject of the effects of aerodynamic shape to save fuel for the employer's trucks. No similar hairstyles, Pong, which is education incurred with an aerodynamic truck accessories available with numerical simulation by a test case is a typical case of 5 off the pickup truck accessory case thaikraba. Case closed wangboriwen seam vagina products. If the front of the car, and extra accessories to the front of the car, and if the surface area of the roof arch car. That results from past research, it is just in theory is not clear. Where the lack of practical results that will be able to prove the validity of the research. Therefore, the main purpose of this doctoral thesis focuses on the subject of design. Create the installation of accessories compatible with the truck to find the rate of fuel consumption of the truck. Every case in which pressure coefficient of resistance test results from a simulation of the accessories installed on the truck in each case will need to have a relationship, and the trend is consistent with the results of the fuel consumption rate for trucks. The concept for such research to be true.Key words: aerodynamic trucks, numerical simulation method
