In this study, an engine room thermal flow analysis of the UTV(Utility Terrain Vehicle), which mainly operated on unpaved roads, was performed. The purpose of this study was to investigate the heat load transmitted to the driver through the passenger seat as a result of the heat generated from the engine. Analysis conditions included the air inhaled into the engine room set in three cases, 50 oC, 70 oC, and 90 oC, as harsh environments during a hot summer were considered. Moreover, the inflow speed of the inhaled air was determined in three cases, 50 km/h, 60 km/h, and 70 km/h, depending on the performance of the vehicle. Under these conditions, the heated air at the upper part of the engine compartment did not cool well because the air inlet area was located below the center of the engine room. |
