Diesel pollutes; shocker!

[albion]

...It makes economic sense to do so so while I make fun of diesel cars, I totally get it.

Yes, it made sense though quite obviously not for long. Things will quickly change.

Next year ?

Why not? A double-decker bus transports what? 80 people on the same space that three single-occupancy cars occupy. A double-decker is way more fuel efficient than 80 single-occupancy private cars, and thus less polluting.

Yes that's true.
I took a bus once, with 80 people who crammed into that bus. I think id rather take my chances in a car!

OK, so you made a good point about buses. We can say the same about trucks. I just wish they were even cleaner though.

Didn't Boris plan to double the congestion charge for diesel, at least before the Sun told its readers to think grime ?

Seems all a bit pathetic considering all the green tax rules were likely mucked up by lobbyists in the car industry.
You pays your money, you takes your chance.

The Telegraph think we will follow Paris, though obviously like Farage and his smokers rights, I suppose we could leave the EU for diesel fume rights too.

 

[albion]

Oh, it seems Boris still plans to charge £20 charge for diesel, just in 2020, over 5 years away !


I quite bet Ken would do it all pretty much today if he was still there.

Old article. IMO annex VI covers air pollution from ships. If you can wade through it, I do it for a living and they seem to make it as complicated as possible to implement. Newer engines are a lot better plus the residual fuel oils being referred to are only allowed to be burned outside special areas - basically in the middle of oceans. Within them (such as North Sea and around Europe) its all ultra low sulphur fuels. There is quite often local national laws layered on top of it as well.
Plus shipping is still a lot more efficient for transport than anything else. As with those big Maersk ships 15,200 containers would be 15,200 trucks being driven from the far east to europe. Thats a lot of road miles.

I work for Clarksons, who do you work for ?

I've already decided my next car will be a dual fuel LNG/Deisel engine

I'm working on the assumption whatever the extra cost to buy initally I'll get back in spades as pure deisel cars wont be permitted in any city in Europe within 10 years and petrol will start to be priced out of the market

 

[TheDoctor]

I don't think it will be. Petrol engines can be dual-fuel, but not diesels, or at least not properly.
A diesel can run with some LNG and some diesel, but not exclusively on LNG like a petrol dual-fuel engine can.

[QUOTE 3418850, member: 9609"]Clearly diesel particulates are a major concern within cities due to the health implications, but what are the concerns / dangers of particles within the countryside and wider enviroment? and in areas with low population densities, is the extra CO2 produced (5-10% more) in filtering out the particulates worth it.[/QUOTE]

Well, most people live in urban areas so it makes sense to design vehicles with that in mind. But with regard to the countryside: concentrations of tropospheric ozone (known to be harmful to the respiratory system) are actually higher than in urban areas. It's a secondary pollutant formed from the action of sunlight on NOx emissions, which primarily are from diesel vehicles.

(the chemistry is actually a lot more complicated than that: http://uk-air.defra.gov.uk/assets/documents/reports/cat05/aeat-env-r-1029.pdf).

Not content with failing to stop noxious diesel emmissions in city driving conditions, it seems some VW cars turnoff the pollutiin control, allowing up to 40 times the safe level.

'VW, the plague carrier' does not sound good.

VW are in serious trouble. It's interesting that they were caught in the US - Californian pollution limits are very strict and it would seem that the testing is better than what we have in the EU. We know that very few cars meet the latest Euro 6 standard: it's time manufacturers were named and shamed.

"The technology to clean up vehicle exhausts is available and costs a few hundred euros."

I fail to see any credibilty in that statement whatsoever. If pollution technology is meant to be in the cars now, there can be little trust for this mk2.

I don't know the science behind it (although I could have an educated guess) I have to wear an anti pollution mask particularly when cycling in London (which is just about every day).
I have suffered a couple of serious bouts of pleurisy and find that if I ride without the mask in a built up and congested area I get very wheezy and short of breath. In the areas of London I cycle in there are usually huge numbers of stationery / crawling buses and taxis (and currently loads of those awful Toyota Prius things).

A couple of weekends ago I got overtaken by 2 diesel cars whilst out in the countryside who both had very heavy right feet to get past me. With just that brief exposure I got very wheezy in seconds and had to stop until it passed. I wasn't wearing the mask as I was riding country lanes and not passing lines of wall to wall traffic.

It showed me how polluting diesels are. It might not be the CO2 but is certainly laden with particulates.

Looks like a Buy opportunity to me.

So VW Group caught being naughty. Again. And to think that many regard this companies products as aspirational.
