SYMBOL AND ABBREVIATION
Explanation
DPF is a filter which removes particulate matter (PM)
including the toxic substance of exhaust gas of the diesel
engine. Exhaust particulate removal equipment.
DPD is an exhaust emission control system, a type of DPF,
which cleans up particulate matter (PM) of diesel engine
exhaust gas. DPD is a ceramic filter which traps and filters
PM of exhaust gas. DPD burns up accumulated PM when PM
increases and regenerates the filter.
Oxidation catalyst for the diesel engine. Diesel oxidation
catalyst oxidizes unburnt fuel and raises exhaust
temperature.
Filter. The filter traps, burns, and remove particulate matter
(PM) by using high-temperature-exhaust gas with diesel
oxidation catalyst. Catalyst is applied onto the filter. This
advances PM burning.
Particulate matter.
The EGR control re-circulates a part of exhaust gas in the
intake manifold and combines it with intake-air. Therefore,
combustion temperature is lowered and generation of oxide
of nitrogen (NOx) is controlled.
