Definitions of system components and operation
 The following terms will define the system components and functional descriptions.
System component Description
Diesel Oxidation Catalyst
(DOC)
This is a catalytic converter that designed specifically for diesel
engines to reduce the emission element such as
hydrocarbons(HC), carbon monoxide(CO), and to do
exothermic reaction for DPF regeneration.
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.
(8) DPF switch
 The regeneration process is the process of
burning and cleaning the soot accumulated in
the DPF while driving.
 This switch is used to select the Regeneration
mode or Inhibited regeneration mode .
- Regeneration mode: If the soot is loaded over
the designated level and the engine is warmed
up enough, the DPF regeneration will be
processed automatically by ECU.
For more
information, see page 3-17, 18 in this manual.
- Inhibited regeneration mode: The
regeneration mode is disabled manually until
operator inputs the signal for exiting this mode.
For more information, see page 3-19 in this
manual.
 And, this switch is used to process the
regeneration manually.
For the detail operating
methods, see page 3-18 in this manual.
