High-Temp SCR

The reasons to develope improved V-SCR for high-temperature applications

The SCR chemistry need to be durable for high-temp applications, too. Of-road full-load drivings. Need to be applicable for the usage together with DPF (Euro5 and beyond). Cu-zeolite limitations (NrO formation, sulphur sensitivity, NO, sensitivity)

> lncrease of pressure leads toimproved spray quality

> Energy for atomizationfrom air pressure

> Typically high air consumption

> Energy for atomizationmainly from air pressure

> Low air consumption

> No contact between AdBlue and
