Bear in mind, Diesel Engines and Diesel Fuel are not synonymous.
Diesel engines can be operated on many different fuels, diesel fuel being one.
We have ferries here with 4 x 15.000 hp engines running on LNG.
Methinks diesel engines has a future, also in cars, despite the ongoing hysteric witch hunt.
I will be trading in my 170 hp (211 hp chipped ), VAG diesel for a 190 hp (to be chipped) same make soon. And no, never seen any smoke in 60.000 kms, with or without chip, and with 50% of cars on the roads here being diesels, not many of them smoke either. As for all the myths regarding particulate filters, nah, I can't be arsed to comment.
Per

Just a PS, my fuel consumption has been on, or slightly below what is claimed by the manufacturer, measured with and without chip as I can turn it on/off by remote. I consider speed limits loose guidelines in case anyone wonders.

Don't Breathe Here: Tackling air pollution from vehicles

In this report T&E analyses the reasons for and solutions to air pollution caused by diesel machines and cars the worst of which, an Audi, emitted 22 times the allowed EU limit. In fact, every major car manufacturer is selling diesel cars that fail to meet EU air pollution limits on the road in Europe, according to data obtained by T&E..............

Diesel particulate filter (DPF)

This technology involves a wall flow filter which will physically trap the solid particulate matter in the exhaust gas, including the solid carbon fraction and fine particles. The particulate reduction rates of DPFs are high, reportedly at least 90-95%........The filter has to undergo a regular regeneration process to remove the accumulated particles........

The DPF must be integrated into the engine control system to ensure reliable regeneration. Regeneration events are nevertheless excluded from the measurement of the emissions in a PEMS and laboratory test. Some evidence shows that the number of particulates emitted during a regeneration is multiplied by a factor of 2 to 10^19.

Those emission are reported nowhere during the type approval process, demonstrating an obvious loophole in the current system that needs to be addressed...........

I fly a pair of diesels which run very nicely on Jet A1. They're slightly modded versions of the Mercedes A Class car engine.

I'm told, by two of the engineers from the modifying factory, that they will actually run on home heating fuel or even petrol. Not certified or wise, but she'll run with that stuff.

I get a little over 175 Kts TAS at 13 US gph (total, not per side) at normal weights. Try that in a Baron, a Seneca or a C310! And all that is with "jet" fuel which is a fraction of the price of old-fashioned petrol.

An added bonus is that I get a deep discount on landing fees at airports such as Zurich because the documented emissions are so low. Of course I presume that there's no monkey business in the ECU firmware.

The banks (rightly) got screwed for mis-selling services. Wonder if VAG can be done for mis-selling cars? I suspect there will be lots of owners out there who have suddenly become environment concious (me included)

I think it would be sad to see the end of the diesel engine in every-day cars considering the levels of improvement that have occurred in the last decade.

As someone who has travelled to Athens every year for the last 20 years I have seen the gradual improvement in air quality of that city. All this is attributed mostly (and to some extent the GFC) to recent advances in diesel engines. And I don't think Athens is the only city to have benefitted from this.

But just as much as I hate Athens, I also hate diesel engines, but that's just me.

Anything for a few dollars more.
You've been happily driving around in your VAG product, but suddenly you feel entitled to a new car or a fistful of dollars.
Rrright.

Yes, I'm perfectly happy with the Yeti, and expect to replace it with a new one next year. Unlike you Per I've rarely managed to get mine below 7L/100k. But as Tesco's say, every little helps, must be the greedy capitalist side of my nature showing through
I suspect this is an industry wide fiddle, wonder where the next shoe will fall

Open acess to the code is the solution to avoid pressures. Patents need to be published.
Patents always are published - that's part of the deal.

Or are you saying that unpatented code is the problem?

I believe that, after several 'cheats', Formula One adopted a standardised ECU.

Let's face it: Diesels are dirty and the only way to make them seem 'clean' is to cheat...

I really shouldn't laugh. I have shares in VW.

For the many folks here crying "US protectionism!!", I have a few questions:
1. Does the big emissions scandal apply to VW's gasoline (petrol) powered cars or to its diesel powered cars?
2. How big is the diesel car market in the USA?
3. Given the answers to the above, does "US protectionism" really make any sense?

KenV,


Calm down, dear.

It's not about the US.

Thread drift

What do people think about 'chipping' your car?

SOPS...."What do people think about 'chipping' your car?" In new road works I slow down to avoid any gravel hitting the body work.
