Thread: WoW: supermini class diesel cars produce more NOx than a 40 tonne truck!

I don't understand what this has to do with World of Warcraft.

Actually it's "Women on Wheels"! Who else would drive a supermini diesel car?

WoW predates WoW by a least three decade years

crazy uh.
Makes a mockery of the talk in that other thread that the limits are set too low and that car makers are passing the test so therefore all okay...

If a truck can meet emission levels in real world driving then why are the limits set too low?

I see bad juju for whizzbox diesos in Europe

Always wondered about the emissions from Mechano-Hogs... And those Travellers Tundra Mammoths! Phew.

For The Horde!

I suspect that the test conditions do not even come close to the real world, and that trucks and buses do better than small cars because the engines operate close o maximum power most of the time, whereas a car engine rarely operates at more than about 10% of maximum power.

Given the new revelations, I wonder if the EU will amend (up) it's supposed emissions reductions and admit it's programmes have been less than successful? (or at least much less successful)

John,
my reading brings the conclusion that trucks meet the 80mg/km limit solely due to urea injection.
small cars blow through this, especially in stop start when they are as you are saying are running low engine loading.

BUT if a truck can meet 80mg/km surely the car makers with 1/10 the volume of fuel being burnt can too!

I guess though there would be customer resistance to refuelling your exhaust tank!
And the extra 10L of urea would blow out a whack of the small cars load carrying capacity!

interesting times

It certainly shows that manufacturers have been avoiding the rules on emissions once their vehicles are out in the real world. I guess there will have to be random testing of vehicles in real-world driving before they are approved for sale.
