1.4 TSI vs. 1.5 TSI

[ms10]

Not entirely sure if this review exactly relates to the new 1.5 TSI, worth a read though:

They missed the bit about the kangaroo feature.

Interesting all right -  you are also right that it is about  the new 1.5. There have already been some changes due to WLTP since it was written though.

 

They may have now tinkered with the Miller cycle mentioned in the article. The current WLTP version (under certification) uses the new "Budack" version of the Miller cycle ( Here's How Volkswagen's New 'Budack Cycle' Engine Works )

 

The review seems to be for the 1.5 before fitting of the Gasoline Particulate Filter (I'm guessing on that one simply because there is no mention of the GPF that they are now getting for Euro 6d compliance/WLTP).

(PA)Skoda’s range-topping SUV is another VW Group machine hit by the switch to WLTP rules, albeit in minor fashion. The previously-available 1.4-litre TFSI engine has been dropped from its lineup, however it has been immediately replaced with a 1.5-litre unit.

You have a really funny definition of 'breaking news'. 

 

This whole topic is about the switch from the 1.4 to the 1.5, and it was started in March! And I think it was pretty much known that the switch would happen from December last year, when the Karoq launched with the new 1.5 instead of the 1.4.

VWD,

Hardly 'latest news' that the 1.4 TSI's were being discontinued then there were 1.5TSI EVO's and then they would need a GPF.

[silver1011]

I've just read that all petrol's with a GPF will utilise AdBlue from week 22, 2019, including the 1.5 TSI .

If true then evidently, with the ecu cheat switch set to off/intermediate, VAG have failed to meet RDE NOx requirements.

 

It will be a pain in the backside, invest in breakdown/recovery companies.....

 

[Ootohere]

Silver1011, where did you hear this about AdBlue and TSI's.

AdBlue is a product designed to combat the emissions from diesel engines, isn't it...? I don't understand how you could simply start using the same stuff with petrol engines.

[xman]

Adblue is used to reduce NOx in an exhaust using SCR (selective catalytic reduction). Can be used anywhere where NOx is a problem including petrol engines.

Lots of discussion on the web. This communication from Skoda UK started it all off...

 

http://www.skoda.co.uk/models/octavia/pricing-and-specs

 

If you select a higher spec model, which opens up the option to select the 2.0 TSI 190PS DSG you will notice it says "AdBlue - YES"...

 

 

 

However! Someone spoke to Skoda UK and they confirmed it was a mistake, and that it would be corrected. No surprise there.

 

But then someone who claims to work for a Skoda main dealer in the UK said they'd just received a 'bulletin' from Skoda UK to say AdBlue was to be phased in for all petrol engines fitted with a GPF from week 22, 2019.

 

This is of course the internet, so take everything I'm saying here with a pinch of salt. It is all hearsay.

[Ootohere]

OK.

Just wondered because when i read that someone heard something i expect they were hearing it and not reading it.

[silver1011]

Corrected...

First I’ve heard about addblue with a petrol engine. Up to now it’s been the filters don’t need it.

[DaveMiller]

Well, filters deal with particulates and adblue deals with (gaseous) oxides of nitrogen: different things. Diesels produce more of both than petrols do (though petrols are worse on CO2) so were first in with particulate filters and adblue.

 

Now that the emissions regs are getting very difficult to meet, we’re seeing filters coming in for petrols, and I suppose that (given appropriate chemistry in the catalytic convertor) there’s a use for adblue there, too.  The adblue never gets into the fuel; it’s injected into the hot exhaust system, where it can deal with some of the NOx.

Nevercome on here, so I've never seen it mentioned elsewhere. Thought it might come as news to folks looking at new ones.

[VWD]

Add to above, pleased to report that shot missed messenger vital parts and messenger is recovering. However messenger feels that in future it might be better not to add any news in case others have not seen it.

[silver1011]

Has there been any further communication around the addition of AdBlue to GPF-equipped petrol engines from week 22 2019 (27th May 2019)?

 

Or was / is it indeed an internet myth?
