Weight is a key criterion for the selection of motorsport components. With the new, ultra-light matrix, it is possible to reduce the overall weight of HJS PE catalysts by a further 50%. The thickness of the catalyst casing can be reduced from 1.5 mm to 0.5 mm by use of the new three-dimensional bionic structure. In combination with the previously used perforated foil (PE), there is a significant weight reduction of over 50% compared with competing products.
The smaller difference in thermal capacity of the steel foil matrix and the casing is another advantage of ultra-light catalysts. This doubles the durability under the extremely high thermal shock loads commonly experienced in motorsport.
