9.8.1 Outline of diesel oxidation catalyst
(DOC)
The DOC energizes
temperature.
9.8.2 Structure of diesel oxidation catalyst
(DOC)
The DOC is constructed with a single core and has an

(1) Diesel oxidation catalyst
(DOC)
9.8.3 Function of diesel oxidation catalyst
(DOC)
During regeneration of the diesel particulate filter
(DPF), the DOC places the post injection fuel into
contact with the core thereof and raises the exhaust
03-CR-E4,03-CR-TE4BG
increase in exhaust gas
(2) Exhaust gas flow
(3) Open end structure
gas temperature to a temperature where regeneration
is feasible.
