Optimization design of air filter housing structure based on computational fluid dynamics

Abstract

The amount of intake resistance of the air filter has a significant impact on engine performance. This article proposes a structural optimization plan to address the issue of excessive intake resistance in an engine air filter. Based on computational fluid dynamics, simulation analysis was conducted on the pressure and velocity fields inside the air filter before and after optimization. The analysis results showed that the velocity uniformity of the air flow inside the optimized air filter was improved, and the intake resistance was significantly reduced. The physical inspection and inspection of the optimized air filter trial sample showed that the intake resistance was lower than the standard allowable value, and all performance indicators met the requirements, proving the effectiveness of the optimization plan.
