Denoxtronic supply module

Electronically controlled delivery of diesel exhaust fluid into the exhaust train

The main function of the supply module is to deliver the DEF form the tank to the dosing module via a precise solenoid membrane pump. There are two variants in the portfolio: The value line without pressure sensor and high line variant with pressure sensor. This pump operated only on demand, when DEF should be injected into the exhaust aftertreatment system. The concept has no backflow DEF line into the tank. During Start/Stop operation, the system stays pressurized. This leads to low power consumption and improved CO₂ balance compared to pressure controlled systems with backflow line.
