Something has gone wrong somewhere anyhow. 25 times the CO2 (CO2, not NOx) emission limit is too high and needs to be investigated further. It could be a measurement error at DUH, on purpose or not, but it needs to be investigated by the official organs.Phil wrote:I'm a little skeptical with the independent tests. Different testing circumstances will lead to different results. Maybe that Espace is producing 25 higher NOx under circumstances not tested? I think the key point in all of this is, is a defeat device being used? - which is what makes this this whole thing a huge big scandal.
It's a little like 0-60mph times. Manufacturers will often claim numbers that are rarely achieved in the real world. Well, some manufacturers perhaps give out more realistic numbers than others. I.e.; Lotus seems to test their cars in a vacuum or in a giant tunnel with a giant propeller generating god knows how much tail wind and perhaps a sling shot system used on aircraft carriers to give jets a shorter take-off range to achieve their acceleration figures. Test it in the real world on aggressive tarmac and summery temperatures and you're hard put to get close to them. How different can it be with these emission tests that test a very predictable, repeatable circumstance?
Wouldnt that mean 25 times bigger fuel consumption?turbof1 wrote: Something has gone wrong somewhere anyhow. 25 times the CO2 (CO2, not NOx) emission limit is too high and needs to be investigated further.

I didnt know that a catalytic cnverter reduces co2 emissions.turbof1 wrote:Very inprobable. The cars run a catalytic converter to reduce the amount of CO2. It simply means that the amount of CO2 exiting the exhaust pipe comes closer to the amount of CO2 produced by combustion.
No worries . I'm no expert. I think co2 is directly related to fuel consumption and nox has something to do with temperature.turbof1 wrote:I was assuming it did this. Looking at information I could be very wrong about it .

3 companies doing that doesn't mean all companies!SiLo wrote:The list is slowly building up then. I'm currently working for Ford and have had people that work in engine development tell me that we don't do anything like this. I don't believe them and am waiting for most car companies to get caught with their pants around their ankles.
The irony that there is a big climate push going on at the moment regarding CO2 emissions as well...
