VW caught by the Yanks for breaking emission laws

Lead has also been linked to violet crime, mainly via brain damage to the young

Forbes Welcome

Now, who did more damage to the environment than any other individual, invented leaded fuel and fluorocarbons i believe. (No its not the CEO of VW :wasntme: )

Are we off topic yet :D

It was Castrol R Racing Motor Oil, it smelled fantastic & I remember it well from watching races at Brands Hatch & Lydden Hill back in the 60's.

And if you'd gone to Mt Coot-tha Hill Climb, a couple of weeks back, you'd have smelt it there too. :cool:

Glad to advise my Gardner 6LX engines meet all original emissions specs 100%.

There's a niche market, fragrant engine oils, hate to think what was spewing out.

Fuel economy might improve, but emssions results would breach the latest American rules. In other words, the cars were poisoning the atmosphere and people.

That's mostly wrong, the problem is that these vehicles burn too little fuel to keep the catalytic converter hot and functioning. They are supposed to do this by reducing oxygen with exhaust gas recirculation. Therefore the vehicles EGT is higher, power is down and economy is poorer than in the cheating VWs. The catalytic converter is supposed to break down the nitrous oxides and carbon monoxide into nitrogen and CO2 and this requires the heat from rich mixtures in the exhaust stream.

Castrol R30, a castor oil in with the fuel was a winner also. Shame it had so much lint in it which meant everything had to be rebuilt after each event.

The Defender should also be given credit for it's longevity, given that, as I once read, more emissions are caused in the production of a vehicle than it will produce in it's life time.(On average).

Nitric / Nitrous oxides, collectively known as NOx which are affected mostly by combustion temperatures within the combustion chamber.
The EGR lowers the combustion temps by introducing an inert atmosphere into the combustion chamber (ie exhaust gases) to reduce NOx.

That's the long and the short of it at least... plenty more reading is out there if you need the full version.

Thanks Mitch. It's time I did the Science. Nitrous Oxide isn't scary though. There must be something more evil lurking at the tail pipe.
Cheers, Billy.

NOx are the components which cause smog and acid rain. Which have various environmental concerns.

I used to run that in my Ducati and Moto Guzzi. Loved it. Gun oil is nice too.

So VW fudged the test and going by the response of joe public you'd swear they've been clubbing baby seals.I find it strange that an American 6.0ltre V8 petrol,sorry,gasoline engine that burns 20ltres per 100 can pass yet a 2.0ltre T/D that uses 5-6 fails?,I also find it funny how joe public again has been lighting up the interweb voicing their anger over the death of all those baby seals from VW's death traps all the while haul trucks pump pollution straight into the sky 24/7 supplying power stations with coal so they can get busy on their keyboards voicing their disgust at the deaths of all those baby seals from some poor bastard who just wants to get home from work.Personally I think the world would be better off if we all drove Prius's and followed the Paleo diet,and didn't breast feed or vaccinate our kids,I know thats bad because some celebrity person said so.
