A high level of NO2 generated on the DOC ensures in combination with a sufficient NOx/soot ratio a good passive soot oxidation on the DPF in normal operation conditions. This CRT effect (continuous regenerated trap) ensures long regeneration intervals for the DPF which saves fuel.
Excellent THC light-off characteristics support and offer flexibility in designing active DPF regeneration strategies through external measures like HC dosing. The PGM loading and the Pt:Pd ratio can be modulated based on DPF regeneration strategies and requirements.
A high NO2 formation at temperature of 200 – 250°C is also helpful for the DeNOx function of any possible SCR system positioned after the DPF in the ATS.
The catalyst coating can be done on metallic as well as ceramic based substrates.
