Rm2s 5th Gear August 5, 2014 Share August 5, 2014 Interesting situation developing in the UK. http://www.theguardian.com/world/2014/jul/29/diesel-drivers-may-face-higher-costs-pollution-battle Diesel vehicles produce high levels of fine particles, like soot, that can cause respiratory problems in children and susceptible adults. The number of diesel vehicles on UK roads has been steadily rising – by 2012, half of new vehicles sold were diesel – in part because of the favourable tax situation and partly because they are cheaper to run. Diesel cars were once thought by some to be more environmentally-friendly than petrol models, because they produce less carbon dioxide, but concerns have been raised in recent years over their air pollution impact. ↡ Advertisement 2 Link to post Share on other sites More sharing options...

Ake109 6th Gear August 5, 2014 Share August 5, 2014 diesel ,are better for every thing most of the modern car don't produce any smoke only the old one ,why not to use diesel Not all emissions can be seen. Besides smoke, diesel emits more fine particulates (not always visible to eye) compared to petrol engines. 1 Link to post Share on other sites More sharing options...

alphard96 6th Gear August 6, 2014 Share August 6, 2014 My neighbour has a new diesel facelifted E class avantgarde, admire the nice front LED lights, super bright and white. However, surprise that the engine produce a weird whining sound (not like the usual taxi clutter but quite obvious), especially when idling.....so every morning, will know if my neighbour has left for work. So diesel contribute to noise pollution. 1 Link to post Share on other sites More sharing options...

Ake109 6th Gear August 6, 2014 Share August 6, 2014 (edited) think is those old euro 2 models garmen should mandate all euro 2 truckers to surrender their vehicle and forced to buy euro 6 trucks You know whats the story behind the Euro 2 saga? Back in around 2006, the Govt decided that all new commercial vehicles registered MUST be Euro 4 compliant. They totally ignored the industry feedback that as a small RHD market, there are not enough manufacturers out there to supply us with RHD commercial vehicles at such an early date. But as usual the scholars ignored the feedback and plowed right ahead. Guess what? Near ZERO new commercial diesels were registered due to lack of supply. Commercial Vechicle COE drop to near zero = PQP become near zero = many renewed their smoky old Euro 2 commercial vehicles for 10 MORE YEARS on a near zero COE. That's why we still have such a lot of smoky old trucks on the roads. Brilliant backfire that did not make it to the news. I thought Euro 5 or 6 the particular will be trap by the particles filter? Yes, if you have a well maintained DPF and if you top up the Ad-Blue tank. Unfortunately, the average commercial diesel vehicle here, ahem, is unlikely to be well taken care of. Manufacturers get their ratings based on paper stats when vehicle is new. How it pollutes after a few years of abuse, doesn't get credited to them.

I would also take advantage if I could. The leopard ah? I think they have a button can push and diesel gets injected directly into the exhaust to create smokescreen.

Baal Supersonic August 6, 2014 Share August 6, 2014 http://www.theaa.com/motoring_advice/fuels-and-environment/diesel-particulate-filters.htmlDiesel particulate filters DPFs reduce diesel soot emissions by 80% but they're not suitable for everyone DPFs reduce diesel soot emissions by 80% but they're not suitable for everyone The exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems – AA patrols are regularly called to cars with the particulate filter warning light on indicating a partial blockage of the filter.Even if your driving isn't mainly urban/stop-start, changes to driving style may be required to keep these systems working properly. If you're buying a new car and plan to use it mainly for town-based, stop/start driving it would be wise to avoid a diesel car fitted with a Diesel Particulate Filter (DPF) because of the possible hassle of incomplete 'DPF regeneration'. dpf warning light How do they work?Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust. As with any filter they have to be emptied regularly to maintain performance. For a DPF this process is called 'regeneration' – the collected soot is burnt off at high temperature to leave only a tiny ash residue. Regeneration is either passive or active Passive regenerationPassive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don't get this sort of use car manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process. Active regenerationWhen the soot loading in the filter reaches a set limit (about 45%) the ECU will initiate post combustion fuel injection to increase the exhaust temperature and trigger regeneration.If the journey is a bit stop/start or you take your foot off the accelerator while the regeneration is in progress, it may not complete and the warning light will come on to show that the filter is partially blocked. It should be possible to start a complete regeneration and clear the warning light by driving for 10 minutes or so at speeds greater than 40mph. If the regeneration is unsuccessful the extra fuel injected will not burn and will drain into the sump. Oil quality will deteriorate as a result of this and the level will rise. It is important that you check that the oil level does not increase above the maximum level on the dipstick as diesel engines can run on excess engine oil – often to the point of destruction. If you ignore the warning light and keep driving in a relatively slow, stop/start pattern, soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will have to take the car to a dealer for regeneration. Expensive repairsIf you continue to ignore warnings and soot loading keeps increasing then the car won’t run properly and the most likely outcome will be that you will have to get a new DPF costing at least £1000. The ash residue which remains after successful regeneration cannot be removed and will eventually fill the filter. DPFs are designed to last about 75,000 miles, but many, operating correctly, are achieving more than this. DPF additivesThe most commonly fitted type of DPF has an integrated oxidising catalytic converter and is located very close to the engine where exhaust gases will still be hot. This heat means that passive regeneration is more likely to be successful. Some models, across a wide range of manufacturers, use a different type of DPF which relies on a fuel additive to lower the ignition temperature of the soot particles. The additive is stored in a separate tank next to the fuel tank and is automatically mixed with the fuel whenever you fill up. Only very small quantities are used so a litre of additive should treat around 2800 litres of fuel – enough to cover 25,000 miles at 40mpg. It lasts about 70000 miles and is replenished during a service – at extra cost. You will have to pay to get the additive tank refilled at some time in the car's life – expect to pay between £150 and £200 including fluid and labour Don't be tempted to ignore a warning light showing that the additive tanks need refilling. It's absolutely essential this tank is refilled as without it regeneration is unlikely to be successful and a new DPF may be needed – at significant cost. Fuel consumption can increase as a result of failed regenerations too. Check the handbookIf you buy a car with a DPF it’s important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life. In most cases there is only a relatively short time between the dpf being partially blocked and becoming so blocked that it requires manual regeneration. AA experienceWe're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways. On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases. DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed. There's no evidence in AA breakdown data that the problem's going away – newer car models seem just as likely to suffer DPF problems if not driven 'correctly' as those built when DPF's were introduced. Removal is not a legal optionIt is suggested from time to time that the answer to failed DPF regeneration is get the DPF removed from the exhaust system rather than pay to get it repaired/renewed. Indeed there are companies advertising just such a service including reprogramming of the engine management software, but is it legal? DPFs are fitted to meet European emissions regulations designed to reduce vehicle emissions of particulate matter (soot) associated with respiratory disease and cancer. According to the Department for Transport, it is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3)) to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use. InsuranceYou must notify your insurer if the vehicle is modified but such a modification could in turn invalidate any insurance cover because it makes the vehicle illegal for road use. MOTFrom February 2014 the inspection of the exhaust system carried out during the MOT test will include a check for the presence of a DPF. A missing DPF, where one was fitted when the vehicle was built, will result in an MOT failure. With an original equipment DPF removed from the exhaust the car may or may not pass an MOT smoke test - a Euro V (September 2009 diesel) is more likely to fail than one designed to comply with earlier emissions standards.
