1. FUNCTION OF DIESEL PARTICULATE FILTER
(DPF)
The Diesel Particulate Filter (hereinafter referred to as the
"DPF") is a filter to capture fine particles (soot and ash) contained in
the exhaust gas of a diesel engine.
The ash content is mainly metallic additives contained in burnt
lubricating oil.
The filter has a honeycomb structure with adjacent cell holes
alternately closed.
In addition, by alternately closing the inlet side and the outlet
side of the exhaust gas, the thin ceramics wall is used as a filter.
As shown in the figure, fine particles in the exhaust gas are
captured when they pass through this thin wall, and the exhaust gas
is discharged as clean gas.
