OT: "Adblue"

Because diesel is still a useful energy source for many people. Superior efficiency to most petrol engines and cheaper to run (even taking into account AdBlu cost). The future is EVs but it?ll be a while before they become affordable for most folk and the charging network improves enough to prevent range anxiety.

Post diesel-gate when many manufacturers were forced to admit that without AdBlu, their engines couldn?t meet the latest emission limit.

Not impossible but 5 years ago the chances are it didn?t have an AdBlu system.

Pass. I?m sure Wiki will tell you.

Yup. My latest car has it. It's mixed with the exhaust to convert the NOx to something harmless.

Mine lasts 5000-6000 miles. Not a faff. Takes 5 minutes to put in, a couple of times a year for me.

They do. Cheaper to buy it from Costco in 5l containers (or more).

It's cheap. Cheap enough to be fairly negligible compares to the seesawing cost of diesel itself. Still generally cheaper than petrol for me. About a pound a litre, in smaller quantities.

It's not trouble. It's cleaner and easier than (say) topping up the oil, and no more bother than the windscreen washer bottle.

New requirement to reduce pollution. There are other ways but fuel consumption suffers.

It's a registered trade name, but can be used by any if the product meets standards. No idea where the 'blue' bit comes from. It seems to spill over into related products - my car has an EcoBlue engine.

My 2018 diesel Kuga did not have that but have noticed the recent Kuga diesel models have this facility.

Ive just bought 20 litres for £14.50 delivered. Our Yeti has done over

Has it still got the dieselgate firmware? :-P

VW diesel busses use it. I'm not sure but does it not stop nox or something by injecting it into the hot exhaust? Brian

Nope, piss is about 2% Urea (and lots of other stuff) and 95% water.

There was a letter in one of the papers about this, sent to that papers consumer expert. The writer filled his/her fuel tank up from the Ad Blue pump (!), and then had to call out the AA/RAC (whatever), but moved the car to the side of the forecourt, thereby sucking AdBlue through the fuel system.

IN Glasgow that might work for petrol and diesel cars :-)

Annoyingly, some of the HGVs that are allowed into Central London have been fitted with cheat devices to avoid spending lots of money on AdBlue. It is perfectly legal to sell the devices too !.

What if you avoid drinking for a couple of days so it comes out really concentrated?

Not all vehicles which meet the latest, E6, emissions specs use it.

That's stunningly lame attempt at humour and shows zero understanding of the situation. It was trying to avoid the cost of fitting SCR and other emissions gear that caused the cheating software to be used. There'd be no f****ng point cheating if you had SCR fitted.

Well, the joke's on you dickbrain, there was a version of diselgate firmware that only used the AdBlue once it recognised it was under test conditions. And Yetis are on the list of models fitted with the EA189 diesel engine.

you tell him ...tee hee

No, that is in fact not really the case.

There is a complex relationship between NOx, fuel economy and Adblue type systems

So much NOx was being generated by super lean burning that ad blue wouldn't have lasted more than a few miles.

Unlikely.

The fuel required to move a typical vehicle across a forecourt would come from what was still in the pump, filter, fuel lines etc.

It is unlikely any Adblue even got near much that couldn?t be flushed or typically was a service part (filter etc).

But diesels always run super lean unless they're working hard.

Andy

I've never noticed an AdBlue pump in a petrol station. I still remember those distinctive red trigger-dispensers for Redex, though!
