AI Technical Summary

Technical Problem

Existing air filtration systems for internal combustion engines face challenges in efficiently utilizing irregularly shaped packaging spaces while maintaining uniform pleat spacing and filtration performance, leading to inconsistent dust loading and potential engine damage from non-genuine filter elements.

Method used

A filtration system with a pleated filter element featuring arched pleated media blocks that intersect to form a lenticular-shaped interior space, ensuring uniform pleat spacing and preventing the use of non-matching filter elements, while maintaining effective media area and filtration performance.

Benefits of technology

The system optimizes space utilization, ensures uniform pleat spacing for consistent dust loading, reduces the need for additional adhesive material, and prevents the use of non-genuine elements, thereby enhancing engine protection and performance.
