sounds like it runs a lean map for EPA testing

 

quote ...

The EPA accused VW of installing illegal “defeat device” software that dramatically reduces nitrogen oxide (NOx) emissions

– but only when the cars are undergoing strict emission tests.

 

40 times the nox it is supposed to emit !!!

 

wonder how it's triggered ? bonnet up , or I think they plug in obd11 socket ?

 

are the euro cars the same ?

Pity their 'defeat device' can't be fitted to the mini

Just been on the BBC news.

I'd be surprised if they are the only manufacturer doing this? I presume this is linked to the egr issues my van also had which costs over a grand to fix every time!

This is old news. Companies have been doing it for years. A lot of super car manufacturers (naively German and Italian) do it as it's the only way their cars will pass EU regs.

But here we have VAG recalling 500,000 cars in the US.

Jaguar F type exhausts are another example but my don't they sound great?!

Then they have been naughty!

Only the V8 ;)

There is some explanation of how it works here:

America just seems so odd to me sometimes.

 

Seems like they all want to run carburettors because their scared of injection in their massive 12 litre engines (putting out poor figures!) but go have a hissy fit at this.

Actually, all new cars have electronic FI due to emissions. However, the issue with the diesels is the particulate coming out of the exhaust.
Ironically, most new cars with petrol (gasoline) engines are using direct fuel injection similar to a diesel to improve fuel efficiency. These engines produce more particulate than regular petrol FI and therefore the tailpipes are black like a diesel. If the regulations become much tighter, the direct injection system will have problems like the diesel

They do, its called a massive air leak system, makes the whole range lean.

I think it funny when these big car manufacturers get busted fiddling stuff.
Also, as mentioned, its funny how the yanks are so pedantic when it comes to emissions and pullution but are quite happy to fang around in honking great trucks, ride monster motorcycles and use V8 powered hedge trimmers.

Are NASCAR still running carbs?

 

I know at work we have to COP test our new cars, an emission test with a few different tests depending on the vehicles intended territory.

The top level NASCAR Sprint Cup cars hace FI. The lower levels intended for drivers to develop racing experience, use carbs.
