New Developments of Ceramic Foam as a Diesel Particulate Filter

Diesel Particulate Filters for both passenger cars and heavy duty vehicles were manufactured using ceramic foam. A new design - the Z-filter family - allows for canning in a conventional manner.

Performance of the new ceramic foam design types was determined employing stationary and dynamic test stand measurements, as well as road testing. Particulate collection efficiency and backpressure can be tailored for a broad range of applications. Z-filters exhibit the already known favourable regeneration properties of ceramic foam.
