CDTi idling burner

Diesel particulate filter as idling burner
Unique Actifilter DB is an integrated diesel particulate filter system and silencer that reduces > 96% of particulate matter (PM) from diesel exhaust gas. The filtered particles (soot) are stored in the ceramic filter. If a preset backpressure or a preset operating time, usually 8 - 10 hours, is reached, the driver receives a signal in the cab that regeneration is necessary. The driver drives the vehicle to a place suitable for regeneration (e.g. outdoors). The regeneration is started at idling speed of the engine by pressing a button on the control and display unit. The regeneration process takes place fully automatically by means of integrated diesel burner that is supplied by the return line of the engine. Depending on the size of the filter and the amount of accumulated soot, regeneration takes 20 minutes. The system works independently of the operating conditions and the exhaust gas temperature. The combustion is controlled accurately.
