  • Product information

    With Departronic, Bosch offers a diesel fuel metering systems for the regeneration of particulate filters especially for heavy commercial vehicles. The system allows the particulate filter to be regenerated thanks to a targeted injection of diesel fuel into the exhaust gas. An expensive coating for the filter or an additional additive tank are not necessary.

    Operation

    Departronic is integrated into the low-pressure fuel circuit. It injects an exact metered quantity of diesel without compressed air support into the exhaust pipe above the oxidation catalytic converter. The exhaust gas temperature therefore increases to 600°C when flowing through the oxidation catalytic converter. At this point, the soot stored in the particulate filter burns off. The flow rate is varied according to the current requirements. The robust and completely maintenance-free system controls the fuel addition as required and independent of the engine injection system.
