ABSTRACT |
The present work concerns an experimental study of the aerodynamic drag on a simplified vehicle body in relation to the underhood architecture, especially the engine block and cooling module positions. To proceed, measurements are carried out in wind tunnel for different geometric configurations. The simplified body includes a real cooling module and a simplified engine block. The measured coefficients concern the aerodynamic drag, the cooling drag and the lift in relation. It was shown that the aerodynamic drag can be reduced up to 1.4 % when the spacing in the vehicle length between the engine block and cooling module is well regulated. According to the results obtained, it was noticed that new configurations could reduce the fuel consumption by up to 0.177 L/100 kms. |
