Another DEF Question

[AH64ID]

Not sure it actually stretches the use. If the injector is dosing at a specific rate and the NOx is not being completely converted, the system will increase the injection rate to get the NOx reduction in range.

I thought the same but didn’t see any notable increase in the rate until the percentage was lower. The lowest I ran was 23.3% and that saw the dosage rate slightly higher, but no higher than the first two tanks of DEF when the truck was new. At my usual 26-28% the dosage was right inline with 32.5%.

Makes sense.
