Diesel Particle Filter system
The particle filter of this system are coated with a catalytic layer. The maximum allowed quantity of sulphur in fuel will depend on the selected catalytic coating. This coating ensures that the caught particulates oxidise at a lower temperature with oxygen. Without this coating, particulates would, after all, only combust at approximately 600 °C. The type of catalytic coating is aligned with the engine type, load profile and the required hydrocarbon reduction by our engineers
The temperature of the exhaust gases is usually insufficient to post-burn the particulates in the filters completely because generators are often loaded relatively low. This is the reason why the DPF-EB has electrical regeneration.
