 DPFiS
– Fuel Additive System
This system uses air to burn the carbon in the filter.
An additive is dosed into the fuel and passes through
the engine to be deposited on the filter. This additive
reduces the temperature at which the carbon will react
with the air.
Johnson Matthey offers an automatic dosing system
(the DOSY 200) for the additive. The additive is held
in an on-board reservoir. At each start-up, the system
determines whether fuel has been added to the tank
and, if so, how much. It then calculates how much
additive is needed and meters the exact quantity into
the tank.
| Advantages: |
passive device which requires no maintenance
between normal services,
can run with higher sulphur fuel. |
| Conditions: |
>380°C catalyst temperature for at least
50% operating time. |
The DPFiS uses the EOLYS™ additive from Rhodia.
