Principle of passive regeneration of diesel particulate trap

人气: Article Source: admin Popularity: Issuing time: 2018-03-15 14:39



Passive CRT / CCRT: Passive regeneration refers to a regeneration method that does not require external intervention. It uses a low temperature combustion reaction of NO and soot on the surface of the filter carrier. Compared with active regeneration, passive regeneration requires a lower temperature, which enables continuous regeneration of DPF.

The difference between CRT and CCRT is that CRT has no catalytic coating for DPF, while CCRT's DPF particulate trap carrier is coated with catalyst. During regeneration, the NO produced by the oxidizer can continue to produce NO2 in the particulate trap to oxidize particulate matter, so that the system can more completely remove particulate matter from the filter. In general, this regeneration system is simple to install and requires less maintenance.
