I deliberately turned off a road to go a different way because I was stuck behind an old black cab, the fumes from which were almost choking me. On its own, that cab was probably worse than 50 new diesel cars.

Quite true, which is why I have to have a little sneer at those people suing VAG. None of them bought diesel for solely environmental reasons, I'll bet. I got mine because it gives a level of performance, economy and cheap road tax that is unbeatable. OK, excellent MPG figures are an environmental assistance in that using less fossil fuel cannot be a bad thing, but that was a sideline benefit. I see buses, HGVs and taxis are yet again not the focus of attention. It would be interesting to see just how much (or how little) difference this kind of scheme will make. When I visited that there London village back in August, the place was choked up with old buses, taxis and trucks. Despite asupposed LEZ and emissions charging. "They should be encouraging the use of buses rather than increasing the cost." Yes. Provided they are clean, not the ancient things I tend to see still running around, chucking out clouds of soot.A friend of mine is engineering maestro for a bus company (depot) and tells me tales of how they look after their fleet. For example, the oldest bus they currently have in service on regular routes is 9, and all of them meet Euro6 guidelines either from the factory or retro-fitted.
The exhaust system on a Euro6 Volvo decker is upwards of £11,000!!!
Most of the buses I see in Dundee are hybrids and when you walk past a busy bus stance there's no stench of diesel fumes, even if a couple are pulling away at the time. Having said that the trains up here are archaic. When I go to the car after work I regularly see an old Intercity 125 with 4 carriages and its sitting idling on a spare bit of line. I think it's the Inverness train.

The buses used round here as school buses are ancient. Old enough for me to have gone to school on thrm, in some cases. Hopefully they have replaced older engines are upgraded emissions systems but certainly some are absolutely old and smoky. Presumably the big operators are using ckeaner buses but the small operators won't have the finances to do so?

If the authorities were serious about improving air quality they start to sweep these old clunkers off the road. Anything visibly emitting smoke should be subject to a roadside emissions test. I'd also make it a criminal offense to decat or remove the DPF from vehicles. Anyone "rolling coal" should be subject to a custodial sentence.

I'm curious to know how the exhuats systems on an EU6 bus work, given that DPFs basically just delay the release of HC and NOX into the air. As far as my understanding goes, once the filter becomes full, it will begin a regeneration phase (assuming load, speed and heat parameters are met) which simply burns off the blockage, usually on a long run on open roads. As buses tend not to run on open roads, how does the DPF ever function or function correctly? Assuming it doesn't just enter a general regen state and burn off all the nasty stuff in the city centre anyway?
Literal smoke and mirrors.

It's the difference between active and passive regeneration - the long run will increase the temperature and activate passive regeneration and around town you would get active regeneration by the injection of fuel into the DPF to raise the temperature and start the regeneration. You can also get "Parked Regeneration" where the vehicle will start to idle at higher revs to raise the temp and start the regeneration process. It's not the case that DPFs simply delay the release of soot and other particles, they actively oxidise them. Buses will often have a forced, static regeneration back at the depot. I'm assuming it's something Blakey gets Butler to do when he parks up for the night.

I look forward to my ban from city centres under Bob's scheme, means I don't have to deal with city folk.

😂 The Land Rover rolls coal if you give it too much throttle before the turbo spools up, but that is often the case with old school mechanical diesels.
Being a responsible, environmentally sensitive soul, I don't do this of course. (Not least because it would mean excessive EGT)

I'll just quit work now and become a dolescum bum.
No diesel = no job.

Politicians simply cannot deal with complex issues. It is beyond them, as they want policy to be by area. Whereas all policy decisions have multi-area effects.
And that they seem quite able to accept completely different solutions to similar problems. If we do not have enough houses, then we must build houses as cheaply as possible (regardless of the fact that houses cause CO2 in building and running, but hey that's a different policy). But if we do not have enough roads and gridlock causes pollution, the solution is to try and force / price people off the road.

In a sort of related story from next year the Scottish National Portrait Gallery aren't going to host the BP Portrait Award exhibition because of who sponsors it (BP, in case you missed it . www.bbc.co.uk/news/50374910This despite, as you can read in the story, the sponsorship allowing free access to visitors many of whom are new but that's overshadowed by the BP sponsorship becoming a problem. So, as the gallery (and all the people around it - directors, artists, grandees of the art world) you want to encourage people to visit your attraction to view the artworks and, perhaps, spend some money in your shop. You want these people to come from far and wide but you won't allow sponsorship from an oil company that's currently trying to diversify itself because, guess what, it can see how public perception is moving. Just how do you, as an art insider, think all these people get to your precious museum and how exactly do you think that is enabled? Same thing for the over-priced coffee you sell in your cafe and, no doubt, a lot of the bland tat you sell in your on-site shop. Is it all made of renewable resources that are hand crafted locally and brought to your museum by people on foot? If these people were half as clever as they think they are they'd be fucking dangerous

I'm off to Bristol to buy myself a beautiful Diesel powered car. I wonder what I'd get for a packet of Starburst (family bag) and a gallon of super unleaded?

Newcastle City Council is repeating its consultation on air quality and the implementation of a ban on non Euro 6 diesels and older petrol vehicles in the city centre and routes through it - the previous proposals were unanimously rejected. The interesting thing this time is that they are saying their modelling shows that if they just bring the ban in on taxis, buses and trucks they can meet the Government targets on air quality without bringing in these measures against private cars - pretty much what we've always suspected, that private cars are not the problem.
