Abstract
A new particulate trap system has been developed. It features both a cross flow type ceramic filter and reverse cleaning regeneration.
The filter is made up of thin plate elements of modified cordierite. Each plate has a row of some two dozen open-end, oval-sectioned channels.
A periodic reverse jet cleaning by compressed air injection blows the particulate off the filter wall and drops it into the vessel bottom. It is burned by an electric heater.
The trap efficiency of this system is above 95%. The durability has been confirmed by a 1000-hour test. Its efficiency will meet EPA 1994 standards with present diesel engines.
