1. OVERVIEW
The DOC (Diesel Oxidation Catalyst) generates CO2 and H2O which are harmless through the
oxidation process of CO and HC. And the DPF (Diesel Particulate Filter) collects PM (Particle
Matter) and is regenerated to reduce the quantity of particulates, HC and CO. But there is a
limitation in reducing the emission of exhaust gas for each system, so the CDPF which combines
these two system is applied.
