3.6. Exhaust Gas Reduction System
Doosan EPA Tier4 interim compliant engine satisfies industrial exhaust gas related
regulations all over the world by utilizing Doosan core technologies.
3.6.1. Tier 4 interim exhaust gas reduction device
The exhaust gas reduction device is enhanced with the aid of DPF where DOC is
applied and EGR to reduce NOx in the exhaust gas.
z EGR (Exhaust Gas Recirculation System) :
exhaust gas circulating mechanism to
reduce the formation of NOx
.
z DPF (Diesel Particulate Filter) : consist
of Diesel Oxidation Catalyst (DOC) and
DPF itself DOC reduces the amount of
HC and CO through chemical reaction
caused by catalyst when DPF captures
particles in the filter and burn them
again to passively-regenerate energy
and reduce the amount of harmful
exhaust gas
.
