VW: small group of engineers did it

Business Week ran a pretty thorough article on the VW fiasco. When the TDI was originally conceived, a urea tank was in the system (urea was considered necessary to hit the Nox regulations). The midway thru the development there was a management shake up and the new top brass didn't want the urea tank, period. Engineers scrambled and apparently could NOT solve the riddle...hence the cheating.
What I cannot understand is, with all the university professors in the US (and world) no one challenged VW with its no urea system until it was accidentally found by UWV under contract with CARB. Talk about sleeping on the job.

Was listening to a new blurp on one of the news channels in the last few days that VW is claiming that the emissions screwup only affected 36,000 vehicles, not nearly the amount that had been previously reported.

There are more than one engine with pollution problem, 2L diesel(11 million vehicles worldwide) and 80,000 vehicles with higher CO2 than allowed. Of those 80,000 vehicles VW is now saying only 36,000 is actually emit more CO2.

Actually, the initial volume was 800,000 gasoline vehicles violated CO2 emission, not 80,000.

I still recall Subaru and Honda not being able to achieve diesel offerings for US standards and skipping offering.
Whatever the actual, measured emissions are when not running in 'cheat mode', they still emit less than the V8 that the American market is so fond of, and in turn they emit FAR less than the 'coal rollers' that are becoming more prevalent.
Contrast tailpipe emissions with the environmental impact of white phosphorous and it starts to become clear that this whole fiasco is a money maker and column-inch filler.
More specifically, of course the engineers did it! Theyre the ones who draw the blueprints. Wether or not the final 'decision-makers' allow it to market or not is an entirely more pertinent issue.

Are you talking about CO2 or NOx? Cause the NOx emissions are FAR over standards.....might you be a bit biased, being from the UK????

Absolute nonsense. My sig car is actually a ULEV, excellent emissions profile and clean as a whistle.
Tell us again how you prefer a road draft tube to a PCV system...

Those engineers have their hind sides covered.
I hear their Christmas present is going to be a one way train ticket to Siberia.

A small group of Volkswagen engineers began working as early as 2005 on emissions cheating software after they were unable to find a technical solution to U.S. emissions controls as the automaker pushed into the North American market, executives said Thursday.

External auditors have already gone through 102 terabytes of data, which he said was the equivalent of 50 million books.

"so fond of" implies popularity, not exclusivity. Further, I didn't name you specifically so you can be pleased as punch with your tailpipe emissions.
My road-draft tube now sees artificial road draft from a vacuum pump. It is > a PCV system because of greater volumetric efficiency, increased intake cleanliness, increased knock resistance and a more constant intake temperature.
Any faults in that particular logic?

I know the EPA's problem with VW diesel is the NOX limit, but at doesn't change the fact that you can take any measurable component of the exhaust stream from a 2.0 diesel Golf, and compare it to the tailpipe emissions of a Cummins (or other popular and widespread NA diesel) powered vehicle, and the Golf will put out less of the component you are measuring. Simply as a product of swept volume - a 6.2 IDI or a Cummins or a Detroit will put out more than the Golf.
Then the LS series of engines, at three times the capacity the % may be lower but the overall volume is higher.

Can anyone explain to me how NOX is a more valid concern than white phosphorous?
So are the emissions measured as grams per mile or parts per million?

Seriously, that is the best VW can come up with is rogue engineers?
How lame.
