Product Description
Continuous Passive Regeneration DOC+CDPF Catalyst
This advanced catalyst system effectively removes CO, THC, NO2, and NOx emissions through continuous passive regeneration technology. The CDPF utilizes the high oxidizability of NO2 for efficient particulate matter oxidation while optimizing SCR system performance.
Technology Overview
The system leverages NO2's exceptional oxidation properties for continuous passive regeneration. By maintaining an ideal NO:NO2 ratio of 1:1, it enhances both CDPF and downstream SCR performance. The catalyst design ensures optimal NO2 concentration management across different precious metal formulations.
