Just saw this on BBC's newsite:

No comment from me - just for info.

 

 

Of particular note:

 

"A Department of Transport statement said all MOT garages would be notified on 26 October they risk losing the authorisation to perform MoT tests if they offer to remove the filters."

 

Finally the clampdown on places offering deletes is starting.

such a shame  :| 

VOSA / DfT can not be bothered to get proper test for pollutants from Diesels,

and they are that bothered about Euro 5 emission vehicles that owners can be wasting money on with Regenerations happening and DPF Cleaning and replacement, when all they did was go in to a Showroom and buy a car, because they thought they would be Economic

and the UK Government had a Scrappage Scheme,

many of these vehicles with DPF are not fit for purpose, City Cars and short distance commuters..

 

Vehicles owned by Local Authorities Councils, Government Agencies etc should be tested first and the Government should be replacing these.

Then stop the HMRC allowing Business users that can just splash the cash to buy the Fuel Burners that are supposed to be Green with low emissions.

 

The UK System of testing & the EU Type Approval System is all pretty much a con.

The UK & EU Governments play at being 'Green' Supporters.

It will not stop non MOT authorised garages from removing them. That cannot be made illegal.

 

You have to ask if so effective at removing soot would those with them removed not fail emissions anyway?

 

Busses are one of the dirtiest vehicles you can follow, if you can see through the smoke that is!

Don't know where you are from but our fleet all run on Adblue and 60% of the fleet is euro 5 standard. There is no argument really to how much emissions busses put out due to the capacity of passengers that they carry. A Enviro400 (Euro5) Alexander Dennis can carry 80 passengers comfortably, you would need 16 cars (5 seaters) to carry the equivalent amount of passangers and even if they where 1ltr eco friendly cars that would mean 16ltrs of engine (16 1ltr cars) to carry the same amount of passengers around as one 4.5 ltr bus putting out half if not a quarter of the emissions of the equivalent amount of cars.

 

 

Adblue

AdBlue is essential for the cleansing and reduction of harmful emissions and is injected into the exhaust gasses before they enter the atmosphere.  It is stored safely within a separate tank on the vehicle, and is specifically measured and applied by spraying into the exhaust manifold, reacting with the gasses within it, creating the cleansing and catalytic effect. AdBlue consumption is typically around 3% – 5% of the diesel consumption for a typical vehicle, dependent of loading weight and other relative factors.

AdBlue is for reducing NOx, not particulates.

the adblue was mentioned in reply to *dirty vehicles*  emissions. 

You need to come to York.

 

All the open-topped double decker toursit buses that circle the city all day every day are terrible. The smoke they emit is more than visible. It renders the back of the bus invisible!

 

Then there are all the school buses, I don't think I've seen one school bus or coach under 15 years old. Again they all smoke like chimney's.

 

First York's fleet are mainly Wright busses and range from 2001 to 2009, not sure if they are any cleaner but they don't look it when sat on tick-over, a nice blue haze floating over the footpath.

 

I'd rather take my chances with 30x DPF'less Octavia's than one of the tourist buses.

Not quite - the last time I did some calculations on air quality emmissions using the Design Manual for Roads and Bridges Volume 11 data (Air quality Chapter) I calculated that a bus would need to be carrying around 26 passengers to break even in emissions terms against the same number of single passenger cars using a typical vehicle within the UK fleet for the same distance journey (taking into account speeds and stopping etc.).  Have more than 27 passengers on the bus and you get fewer emmissions than 27 cars, have 25 passengers on the bus and you get more pollution than 25 cars.

 

Now that was some time ago and things will have moved on (the UK bus fleet is getting better all the time (in certain places) but so is the UK cart fleet.

 

However, consider how full your average bus is off-peak (about 5 passengers if your lucky round here) and buses become more polluting than single passenger cars would be.  the only reason to use them in that case is because they are making the trip regardless of how many passengers are on board (it could be zero so how environmentally freindly is that).

 

To my mind the future for environmentally friendly public transport is to use it to deal with peak demand during peak hours (when it stacks up environmentally) and use lighter, cheaper, smaller capacity and less polluting vehicles at other times.  All in conjunction with a wholesale switch to better fuels (for example the bin wagions round here run on gas...   and gas powered bus trials have been undertaken in Norwich etc.

 

Oh and I  forgot to say - if you have Euro 5 buses in Liverpool you are WAAAY ahead of most of the country which is still operating on Euro 2 or 3 public transport vehicles.

Need to offer a DPF removal and cleaning service.... Noting - serious face - to the customer, that the car would not be road leagl.... strictly, until it's refitted.

Here in SW Scotland, Stagecoach 52 seaters often travel empty belching out black smoke. One was so bad one one of my journeys stuck behind from Dalmellington to Ayr (12? miles) that I reported it to the company and VOSA.

Everywhere I have driven buses, both smaller towns and larger towns/citys have very few buses running round with 5 people on. Bus companies cant afford to run a bus with that few passengers and the council certainly wont pay for it, even more so with the amount of cuts made. Even through the evening until late most of our buses and the buses I've been to run at a minimum of 50% full, through rush hours they are rammed and pretty close to full most of the time. If you worked it out properly over the whole week, both the quieter trips and the ones with 50/60/70/80 people on, a bus would be far more economical and better for the environment than everyone using cars. I think it's a bit of a flippant comment that some people (not saying you in particular) say how buses run round empty after seeing one service thats quiet or a bus dead running, I think most would be surprised if they spent a day on them. 

 

I'm not denying that some small villages and towns will have light loaded buses but I dont think it's a situation thats is replicated over the majority of the UK. We run a slightly lower frequency during off peek times then up it during rush hours. The Oxford trips I recently done use Enviro 400's all the time but they are fairly busy most of the time anyway. 

 

As for ages of buses, we dont have a particularly new fleet but I think out of all our buses (about 70) 5 are Euro 3, 10 or so are Euro 4 and the rest are Euro 5. It's also worth noting, a fair amount of buses have filters added aftermarket to get in under the LEZ for cities such as London/Oxford, these get dispersed to other depots over the years so while a fair few look old they will still be fairly clean. 

 

Things like school buses and sightseeing buses tend to be older because they dont make a huge amount of money to invest much into them I suspect, in reality they make a tiny part of buses on the road, much like V10 diesels do on the road for cars. 

 

Massively off topic

Which diesel engined buses are fitted with DPF's? Euro 3, 4 or 5?

 

If DPF's are now writing off 8 year old car's and the life of a bus is generally much longer than a car then I bet the operators can't wait to see the DPF warning light frequently appearing as their vehicles begin to age.

 

I can just see it now, the driver shouting over his shoulder as he turns off down the motorway slip road "we're going to be a bit late to town today ladies, I need to give the old girl a blast up the motorway!".

I am sure as demand increases for replacement DPF's the cost will fall, just think how much a catalytic converter was when they first appeared on cars, now they are affordable.

 

 I have a 330d and this has a particulate filter, it is a bit of a worry but I am sure it can either be cleaned or replaced, if it is a grand then it is a grand, still cheaper than buying another car.

I have replaced the thermostats and I know it regions at the minute, estimated life is 120k miles and as are car has done 100k this is not far away.

 Worst case scenario is that it gets deleted and a phone call to a man I know for the necessary MOT, not to mention improved performance from less back pressure

 

 or £700 for a replacement DPF

Some interesting stuff in the BMW thread regarding high back pressure preventing regens and the glowplugs being called into to action to increase temperatures if the thermostat turns faulty. All clever stuff.

 

In my 2002 320d E46 (non DPF) I was able to floor it after a long steady motorway cruise and leave a long black line of soot on the road surface!

I do love it when people say your driving around all day carrying no one haha

 

i was on a quiet route today and payed in £200 thats just tickets and must have bee twice as many passes.

York have just got a load of Optares new all electric buses.

 

Not completely electric though, they still have a small diesel generator for the heating.

 

We have a batch of electric buses, not hybrid. Same model as above but wheel forward and short wheelbase. Thats impressive that they can do a whole day on electric, I can only assume their working day is very short on P&R. Ours do a full 15 mile/1hr route through the town, charge at each end. 

Thats the Wright Commander 2's

 

 

And thats the Enviro 400's

 

 

Some pretty good kit compared to some places around the uk !

I wasn't actually being flippant but basing my comments on my knowledge of bus occupancy surveys that I have had commissioned as part of my work in both Norwich, Doncaster and Sheffield as well as knowledge of such surveys in other cities and towns.

These tend to use bus boarding staff to count occupancy at stops as well as numbers getting on and off the bus so are very good at identifying how many pasengerscare present as that's what they are done for.

And yes you are right that operators will not generally run a loss making service but passenger transport executives and thier successors have often paid for such loss making services so that some form of provision is in place, regardless of passenger numbers. So it does happen.

Very good compared to round here. On the route past my house were lucky to get something newer than a 51 plate and often they are much older so pre 2001 Dennis Tridents or old Volvos
