A study of tire pressure and tray volume affected to fuel consumption
MetadataShow full item record
The aim of this project is to study the fuel consumption from the effect of tire pressure and tray volume. In order to tire pressure is consist of 2 conditions by: Road test and Roller test Bench. Their test is classified by 3 cases: standard tire pressure, lower standard tire pressure and upper standard tire pressure. Furthermore, the lower and upper standard tire pressure was compared with standard tire pressure. In case of seal and unseal of the tray volume was test with 2 postulates by Road test and water tunnel (model). The results of experiment with 3 cases of tire pressure found that the lower standard tire pressure (25/37 psi) given to the maximum fuel consumption when compare with standard tire pressure 4.6%. While the minimum fuel consumption is upper standard tire pressure (33/45 psi) or 1.29%. Furthermore, the trend of those conditions was in the same direction. For the result of test in term of seal and unseal of the tray volume discovered to the fuel consumption in case of seal is lower than unseal of the tray volume 1.63%. And the result of test of the water tunnel has been the same direction with the Road test.
