V A G, Ducati And Sceptic Tank Lawsuits

Discussion in 'Ducati General Discussion' started by johnv, Sep 22, 2015.

  1. nitrous oxides are formed (bearing in mind it's been ten years since i have been on an engine management coarse) when oxygen and nitrogen combine through heat and pressure in the combustion chamber. in the past and still do. they use an Exhaust Gas Re circulation valve (EGR) to reduce the levels of oxygen in the combustion chamber the amount of EGR used depends on temp and engine load. fiat/alfa if i mind right where developing a new system that didnt require an egr valve (could be well out here) by messing with injection duration timing.but don't quote me on that.
     

  2. And the Audi A1, Seat Leon and Ibiza.............All the same engines and basic chassis...........

    (Could also be Porsche if it was diesel..........)

    ..........anyway, it looks as though it affects all Europe VWs as well.......

    So I guess we will find out that the petrol engine tests have been fiddled.......

    In fact I bet the fiddling applies to all diesel car manufacturers, not just VW based ones.

  3. Germany WW2 and Germany 2015...............

    Trainloads of people; registration; ghettoes; and gas emissions.

    You couldn't make it up really.........

  4. All 1.4 and 2.0 Diesel engines. Ouch.
     
  5. BMW shares have dropped now......

    .......makes you wonder what will come out about them......
     
  6. They road tested a BMW (and some other cars) alongside a VW and the BMW was accurate.
     
  7. Looking forward to a fire sale of cheap VWs soon!
     
  8. I can just picture it... The day after this all comes out, you crash you 14 plate Golf TDi and it's a write off. Well sir, trade in value is £2,750 as of yesterday. Sorry [emoji31]

  10. Find it hard to believe that BMW don't do exactly the same and very probably all the others too.
     
  11. The way the rules are written and the cars tested, its all about governments extracting more tax from you, me and the manufacturer.

    Obviously this year the US government and States have a bigger short fall than ever before so have to find new ways of fleecing money from companies.
     
  12. one mans efficient engine is another mans inefficient one. The green lobby wants less emmissions per litre, I want more bhp - ft/lbs per litre.
     
  13. Land Rover starter kits?????
     
  14. Your a farmer, your wife works for the tax office. Are your kids dreaming of being traffic wardens when they grow up? [emoji6]

  15. Adblue is a PITA,commonly known as ,"pig-piss",by my drivers,but has to be used for HGV's using SCR technology to bring down emissions
    Only Scania and MAN went down the EGR,(no Adblue required), route to achieve Euro 5 (?),but I understand they have had to use SCR and EGR to achieve Euro 6.
    The "defeat"/VW thing is not recent news,was discovered in 2006!
    Cycle beating
    See also: Volkswagen emissions violation
    For the emission standards to deliver real emission reductions it is crucial to use a test cycle that reflects real-world driving style. It was discovered that engine manufacturers would engage in what was called 'cycle beating' (cheating) to optimise apparent emission performance only during the emissions test cycle, while emissions from typical driving conditions were deliberately left much higher than promised or tested, undermining the standards and public health. In one particular instance, research in diesel car emissions by two German technology institutes found that zero 'real' NOx reductions in public health risk had been achieved despite 13 years of stricter standards (2006 report).[19]

    An independent study in 2014 used portable emission measurement systems to measure NOx emissions during real world driving from fifteen Euro 6 compliant diesel passenger cars. The results showed that NOx emissions were on average as much as 7 times higher than the Euro 6 limit. However, some of the vehicles did show reduced emissions, suggesting that real world NOx emission control is possible.[20]

    In 2015, the Volkswagen common-rail TDI diesel engine emissions controversy involved revelations that Volkswagen AG had deliberately falsified emission reports by programming engine management unit firmware to detect test conditions, and change emissions controls when under test. The cars thus passed the test, but in real world conditions, emitted up to 40 times more NOx emissions than allowed by law.[21] An independent report in September 2015 warned that this extended to "every major car manufacturer",[22] with BMW, and Opel named alongside Volkswagen and its sister company Audi as "the worst culprits",[22] and that approximately 90% of diesel cars "breach emissions regulations".[22] Overlooking the direct responsibility of the companies involved, the authors blamed the violations on a number of factors, including "unrealistic test conditions, a lack of transparency and a number of loopholes in testing protocols".[22]

  16. Threads merged :)
     
  17. @Lightning_650 Here's a question about the use of AdBlue (i.e. Urea solution). As you rightly say, some diesel engine manufacturers specify a system which involves the injection of Urea into the exhaust stream which enables nitrogen oxides to be reduced or eliminated. The vehicle has to carry a tank of liquid Urea, which has to be topped up frequently; if the Urea runs out, the system no longer works and the NOx emissions increase dramatically.

    The question is: Do operators really maintain the supply of liquid Urea, as they are supposed to? Or do many of them quietly drop it in practice, leading to higher NOx emissions? Not while the vehicle is being tested, of course.

  18. Strueth. No wonder the entire industry is bricking it.
    People might even decide not to change cars every couple of years and find out that they actually last a couple of decades and hundreds of thousands of miles. They will be saving a fortune and helping the planet. Cue millions out of work.
    Oh well. Swings and roundabouts, eh?

  19. I think you want to take what a "motor industry spokesman" says on Radio 4 in the morning with a large salt cellar. In fact, just about everyone they invite on that programme talks completely PR-mediated bollocks on any subject.

    Ze clever thing about the VW scam was that the software recognised when the car was being tested, and then changed the engine characteristics. So it didn't matter a damn if the car was randomly tested. If they could do it in the US, they could do it in the EU. In fact, if they had developed the mindset that it was OK to do it in the US, you would expect them to do it in the EU too. And if they had invented the wheeze for diesel, why not for petrol? After all, programming some software is a lot easier and cheaper than implementing tricky engineering solutions.

    And if VW had the wheeze, why not the rest of VAG? And indeed, why just VW?
    I suspect the world's car-buying public (lorries too, maybe) has been lied to on a massive scale.

    It's just not the same, at all, as fitting your stock pipe for the MOT and putting the Termis back on afterwards. The subterfuge is the same, but the scale and corporate implication is several orders of magnitude greater.
