Optimal Design of Off-Road Utility Terrain Vehicle Air Filter Intake

The air filters applied in utility terrain vehicles (UTVs), which are usually driven on dust-prone unpaved roads, employ a two-stage cleaner that increases the lifespan of filter element by using pre-cleaner stage intake housing to centrifugally separate any dust particles contained before sending cleaned primary filter. Thus, maximizing centrifugation capacity properly modifying geometry passage is important ensure engine performance and lifespan. was therefore optimized this study terms inclination angle location computational flow analysis maximize centrifugal removal particles. resulting overall efficiency per pressure drop were then used as objective functions particle according speed. method demonstrated for optimizing can be improve prolong UTV engines.
