摘要: This work reports on experiments carried out a real passenger vehicle in large wind tunnel to investigate the effects of car inclination underhood cooling. The vehicle’s is instrumented by thermocouples that measure temperatures many components during different functioning modes. Measurements are for three thermal points at speeds 90, 110 and 130 km/h. In these engine was operation front wheels positioned test facility with power-absorption-controlled rollers. Three inclinations investigated: flat, uphill downhill. results show inclination, even if very small, can have significant cooling must be taken into consideration numerical simulations controlled experimental tests. It shown down-hill up-hill increase components, air zones parameters underhood, higher effect inclination. Temperature increases constant-speed driving phase than soak phase.
