Definitions
- a module commonly referred to as a diesel oxidation catalyst (DOC) may be installed at the front end of the DPF, and when the diesel engine exhaust gas passes through the DOC, the DPF is mounted at the same time while oxidizing HC (hydrocarbon) and CO. It can oxidize NO2 which can lower regenerative combustion temperature.
- DOC diesel oxidation catalyst
- LNT module is defined as a module for reducing nitrogen oxide in two steps.
