"How it works:
Old software used fuel injection only during power stroke, which makes a lot of power and maximises use of fuel in efficient way, but exhausted gases are not fully burned.
In modified software car inject fuel during exhaust stroke in order to burn off soot and make cathalitic converter more efficient, but at cost.
Injecting fuel during exhaust stoke works agains piston and slows it down, so engine makes less power, and also consumes more fuel.
They did market research, and found that people would not refil their urea tanks, and urea injection system is expensive.
If these cars had urea system (like add blue Mercs) fuel consumption would be low and they would not have polution problem."
"NOx је уопштена форма за моно-азотне оксиде(NO и NO2). Ови оксиди настају приликом процеса сагоревања, нарочито приликом процеса сагоревања на високим температурама."
U prevodu: Manje goriva - veca temperatura - vise NOx i obrnuto. Sto su promenili u opozivu za EA189 motore.
