In contrast, these components made up only about 10–20% of the coarse fraction between 2.5 and 10 µm. The coarse fraction was dominated by aluminium, silicon, sulfur, potassium calcium and iron, which made up 40–50% of its mass.

How The Diesel Particulate Filter (DPF) Works? …

Diesel Particulate Filter consists of silicon carbide. It can filter about 99% of solid particulate matter from the exhaust of a diesel engine. The soot particles or the carbon particles deposited on the filter channels are oxidized into carbon dioxide (CO 2 ) at exhaust temperatures above 600 o C.
