I was reading my buddy's owners manual on a newer ram diesel, from the last few years. It says it burns more fuel in order to keep emissions lower. It actually says that in the manual.
That's why the newest Rams and pretty much every other manufacturer have gone to the urea injection systems. The whole lets burn more fuel to reduce emissions never really made much sense.
Imagine, if you will. A world where everyone's concerns, priorities, needs, wants and financial state are not the same as yours…
Uuhhhg. Really Dave? Maybe head on over to Europe bro.
You post wreaks of NA entitlement.
Isn't this a thread themed towards our desire for NA manufacturers to bring us efficient mid size diesels?

Explain the SCR system please
They plug up.

urea just goes after the NOx gasses in the exhaust
the whole "burn more to emit less" is for particulates where they run a DPF filter that eventually gets full and needs a regen, they use diesel to burn off the particulates that the filter catches during a regen cycle, that's where the whole "it burns more fuel to make less emissions" comes from
its pretty much job security for mechanics.
Ha Ha! Made you look.

And the fuel that is oxidized during a regen doesn't amount to much and is only injected during a service or autoregen. Passive regens use exhaust heat only to activate the catalyst.
The big question is,when it comes to after treatment,what would you prefer,20 bucks a gallon for DEF or 5 bucks a gallon for diesel(and no extra tank or pump)?

US DOE estimates savings of one and a half million barrels of oil a day if a third of all their automobiles were running diesel.

So essentially my comment that the OEM's are using extra fuel to clean up the emissions was bang on. Yes it is in small amounts but you are still burning extra hydrocarbons to pass the sniffer test.
IMHO the DPF system is very flawed. And the manufacturers are proving this by moving towards urea. Which has another whole set of issues, of course.

Yeah, this thread is full of babies. Who gives a crap about UREA, it'll be gone soon.
yep, butthen we'll have to burn more deezil!!!
btw, it isnt actually burned in the doc/dpf,rather it's oxidized

8 mpg of fucking awesome!!!!!
