Diesel Oxidation Catalyst (DOC)
An oxidizing catalyst positioned in front of the Diesel
Particulate Filter (DPF) step that uses post injection
unburned fuel to actively regenerate the DPF.

Diesel Particulate Filter (DPF)
The Diesel Particulate Filter (DPF) is a device that
captures and combusts PM in the exhaust gas.
Physically captures the PM using a filter which
spontaneously combusts when exhaust gas temperature
is high.
However, while exhaust gas temperature is low PM
does not spontaneously combust the pressure
differential between the inlet and outlet of the DPF is
detected and the PM is combusted using a heat source
generated using DOC to regenerate the filter.

Intake Throttle Valve
The amount of air intake is regulated by the angle of
the throttle valve and the exhaust temperature is
controlled when regenerating the DPF muffler.
