System component Description
Diesel Oxidation Catalyst
(DOC)
This is a catalytic converter that designed specifically for diesel
engines and equipment to reduce the emission element
such as hydrocarbons(HC), carbon monoxide(CO) and
unburned fuel.
Diesel Particulate Filter (DPF)
This is a filter and an after-processing component that captures
soot in the engine exhaust gas, and to prevent the filter from
clogging, the particulate matter will be automatically burned into
CO
2
at a high temperature by regeneration process.
