Effective regeneration of DPFs

Fuel Borne Catalysts (FBCs) reduce the temperature at which soot burns.

The FBC is added to diesel fuel either by additising bulk fuel or by use of an on-board reservoir that adds it to the vehicle fuel tank or the fuel lines.

The FBC is burnt with the fuel in the engine and is carried into the DPF along with the particulate matter (PM) where it catalyses the reaction of soot with oxygen in the exhaust gas. The FBC lowers the temperature at which the reaction occurs from over 600°C to around 350°C depending on engine emissions.

Performance	Fuel Borne Catalyst DPFs	Catalysed DPFs
Fast and effective DPF regeneration	Regeneration is fast and complete	Slower regeneration
Tolerance of high levels of fuel sulphur	Tolerant of high levels of fuel sulphur	Sensitive to high levels of fuel sulphur
Independence of engine NOx/PM ratio limits	Regeneration is independent of engine NOx/PM ratios	Regeneration is limited to certain engine NOx/PM ratios
No increase in NO2 emissions	Do not produce additional NO2 emissions	May produce additional NO2 emissions
