Microwave regenerated diesel particulate trap

摘要

A self-burncleaning sootfilter for a diesel engine comprises a sootfilter element (2; 32A, 32B) for filtering soot from an exhaust gas of the diesel engine, and a heating system arranged for increasing the temperature in at least a part of the sootfilter (1; 31). The heating system comprises a microwave generator (6; 36) for generating microwaves. The sootfilter element (2; 32A, 32B) is substantially transparent for the microwaves generated by the microwave generator (6; 36) and the microwave radiation can be absorbed by soot. <IMAGE>
