Abstract
It is now well established that car inclination influences component temperatures in the car underhood compartment [1, 2]. This study presents an analysis of these effects by measurement of the heat flux that enters or leaves the underhood components. We report underhood thermal measurements carried out in wind-tunnel S4 of Saint-Cyr l'Ecole on a passenger vehicle. The underhood compartment is instrumented with 40 surface and air thermocouples and 20 fluxmeters of normal gradients. Three configurations of car positions are investigated: the flat, the up-hill and the down-hill inclinations. Measurements are can-led out for three different car thermal functioning points.
