Odour (PM) contributes to the formation of respirable and odour-causing particulate matter.

The DOC (diesel oxidation catalyst) removes the soluble organic fraction (SOF) of the particulate

PM (Soot) – fine particulate matter is responsible for regional haze

A DPF (diesel particulate filter) traps the soot in the filter and the filter is regenerated by NO2 from the catalytic coating.

> 85% PM

Low to moderate

PM, HC and CO

Since the DPF is catalytically coated it will remove all three pollutants

> 85% PM, > 80% HC and > 90% CO

Low to moderate

NOx contributes to the formation of smog and ozone increasing the respirable material that can pass deep into the lungs.

The SCR (Selective Catalytic Reduction) catalyst system includes SCR catalyst in a housing, urea dosing pumps, urea control system and urea storage tanks

> 90% NOx

Moderate to High
