Filtration Challenges and Conical Filter Development for Engine Air Induction Systems 950941

Today's automotive Air Induction Systems (AIS) are designed to deliver overall superior filtration performances because of increased engine protection requirements. In addition it must also meet packaging requirements, higher flow rates, lower system restriction, serviceability and induction noise. Studies have shown that the size and concentration levels of dust ingested need to be controlled to reduce engine wear. Major air filtration technologies currently available and used on AIS are also presented. Criteria for filter selection have also been discussed based on field data. Engineering and design parameters are also briefly discussed for developing robust engine air induction filters.Development of a new conical filter element is presented for the Ford ‘Conical AIS’ including performance data. This development also includes process/manufacturing and engineering specifications for the new conical program. This conical filter is currently being used on the new 94 Mustangs with additional applications on passenger cars and light trucks in the future.
