Must have a Rotor  :-)) :-)) :-))

Correct, modified to inject 2 stroke oil into the combustion cycle rather than sump oil. Cleaner burn and also means you can use fully synthetic in the engine

It's nothing new, its happened for years in one form or another.

My Suzuki Hayabusa ( Guinness Records, fastest ever road bike) had similar mapped into its ecu. Between 4900 rpm and 5100rpm the ecu automatically leaned out the fuel/air mixture to conform with mot regulations which are read on a bike at a steady 5000rpm. Outside of that range normal service was resumed and missile like acceleration new no bounds.

When I started driving the ecu was my right foot
or wrist depending on the number of road wheels.
The mode of transport was also maintainable with
a decent set of tools a bulb on a bit of wire and if
you were posh a torque wrench.
Ooh nearly forgot the strobe light. :D

Other than the press & the eco warriors.. Does anyone really care ?.  They may not be as low emissions as thought but they are still a lot lower than 10 years ago I would imagine..

Diesel is " THE FUEL OF SATAN " I've endured the stink of it for 50+years in the Engineering industry, if it could be suddenly banned I'd be made up , unfortunately it's part of the 'Cracker Plant' process & cant be side stepped as the various vapours are drawn off at different levels in the tower and distilled . . .
What's worse now is "BIO DIESEL" That's made from anything that can be broken down , used chip /  curry / fish cooking oils and rapeseed oils  , if you think Diesels bad wait 'til you get a lungful of this stuff  %%  ,quite a few of the Heavy Hauliers are using BioDiesel now , one of our Hauliers was BANNED from backing his wagons into the loading bays ,  :police:  not only was the 'aroma' appalling everything seemed to get an oily sheen on it  O0 
Have you noticed the price of a litre of Diesel is now LOWER than Unleaded ? and LPG is slowly going up? HMM . . .

 >:-o I care because I am not getting what it says on the tin,I live in West London and the air quality is pretty poor at times and this is killing a lot of people in big cities,the car manufacturers are saving a fortune by tweeking the engine management units and not spending the money on R&D which will make engines cleaner which I think we all want,the I.C,engine must be getting to the end of of its development and now it is the time for the electric car to take over,when I was a kid we had trams,trolly buses, the railways,coop, UD all used electric motors for loyal deliveries, perhaps we should return to using electric transport......Ray. >:-o

Many motorists are more than happy to remove their diesel particulate filter to improve performance and stop those annoying warning lights. They don't care that this means that all the crud is just blown out of the exhaust instead, only that they hope that removal of the DPF will not be noticed at the next MOT inspection.
Diesels have simply got too complicated with all the bolted on sensors and emissions gadgets, all of which cost an arm and a leg to replace when they go wrong. I have switched back to petrol now. Electric cars will not become practical unles there is a breakthrough in battery technology to give them a range of at least 300 miles on a charge.

This is a great debate and one which many a good point has already been mentioned, one of which really intrests me........ Electric cars, bikes etc..... Colin, I half agree with you, I understand that people want electric cars that do decent distances on a single charge but it's not a breakthrough in battery technology that is preventing this happening it's the opposite!
 
Battery technology is being improved upon all the time. Imagine this, you buy a state of the art electric car, it does 300 km per charge and cost you 15000 pounds to buy. One year later technology has increased that range to 500 km but the new battery is incompatible with your present system, your 12 month old car would be almost worthless as everyone knows that another 12 months down the line there will be a new battery and better range. SO, what needs to be done is some sort of agreement on the battery size or size and shape throughout the industry so that any new technology can be fitted into any old car regardless of make.


When horses got replaced by internal combustion people must have laughed ha but we're do you buy this petrol stuff from? But even with the advances in technology it's still the same petrol you put into a Ferrari as you put into a ford pop!..... Ok give or take but you know what I'm saying. If I buy an electric car today that does 100 km on its present set up I want to know that the same car will be still usable in 10 or 20 years with its latest battery update. It may not be as good as a future car with the same battery (like comparing MPG on an Escort Mk1 with a modern day focus but at least they both run on modern fuels)


If manufacturers can't agree between themselves about battery specs then they will all end up with different size and shape batteries none of which will be transferable and all of which will be soon outdated. Unless you can afford to lose so much money who is going to do it?



I would love to buy a new electric car tomorrow but come 12months when the new batteries double the range and I can't sell mine for even half the price, or after 3 years it would be like being stuck with a 3 year old Ford Focus that does 8 mpg when the new one does 70.


So what do we think, battery size and shape agreements throughout the industry, or guaranteed buy back price on used vehicles by vendors?


Not a rant just a criticism of how things are being handled by manufacturers with modern technology.  U2

Colin in no means am I having a pop at what you have said BUT ......Our Audi recently had a particulate filter problem at 70000 miles...had a quote off audi to replace said exhaust piece      1480 and they wanted it  for 2 days ........So we had the filter removed and a total remap of the Ecu cost 400 Done in Half a day........Joke is not only the company I used and Audi would have had to remove the said exhaust and replace it.

MMMMM odd isnt it  the last 2 Mot emmisions were compared to the one carried out yesterday and the Emissions are LOWER than the previous 2 ad an actual power increase of 28 BHP and the MPG has actually gone up by 6MPG.

The thing is by removing the DPF the engine is now running far more efficient and so will not be giving so much pollutions into the atmosphere.

The std Mot test to check if a DPF is fitted is purely visual they can not fail it if the box has bee rewelded up...ad as long as it passes the stationary test of reving up to 2500rpm and not going higher without dipping the clutch the it is a Pass..........

I must admit I was rather sceptical about this process till I had it done but it works

Biggest thing this weekend that made me chuckle was whilst working doing a road closure  was when a chap stopped me and asked where the nearest Audi dealer was as he has this .....in his own words..I got bleep bleep bleep particulate filter thingy or something up on my dash and I got NO POWER....... So being the kind person I am told him what to do .....drive at 2k constant down the road on his way home to Manchester and it would clear.
Thing is this particular Audi was only 6 days old and had covered 1500 miles....WOULDT like to be the salesman in his local dealership o Monday morning as he was taking it back for his money back !!!!!!!!!!!!!!

This to me really summed up the old PARTICULATE FILTER SAGA

Stavros, my brother told me the same thing, drive at constant Revs for 10 mins and something heats up and 'burns' the filter clean. I don't know where all the burnt bits go but it works, I set my cruise control on the way to work and clear it. I have been told that if you change the revs the 10 minute timer resets and you have to start again? You can hear it start on some cars apparently but who knows, owners, garage mechanics, lying manufacturers?...........

Constant RPM for 10 minutes  {-).......in a laboratory?...or in a lavatory?  :embarrassed:

I could get my new $15.00 Chinese quartz strain gauge hooked up to a few linkages & pulleys then add 1/2 a house brick as the mass applied in the fulcrum to the vehicles accelerator.......

Could also use my new $12.00 Chinese digital laser tachometer  to monitor the preceding's  :o..........& just to make sure my testing was valid.....I could monitor the engine temperature with my new $13.00 Chinese digital laser pyrometer ........ :kiss:....

We have a beautiful new [mega expensive] multi franchise motor vehicle sales showroom in Wollongong....yes VW, Audi, Jaguar, Skoda, Ford & Land Rover

I could get all of my test gear in the back of my 2006 [petrol] Mitsubishi Lancer VRX wagon & set up a $10.00 signage offering "cut price 10 minute constant RPM test runs" .....just around the corner from the car shop.......might be a real $$$$$$ spinner......Derek  %)

Thing is with these DPF's if they get above 40% full of soot they will not clear.....another way of cleaing them up is to remove the DPF ad immerse it in a bath of brick cleaner and it will remove the soot but it is only a temp cure it will block up time ad time again........when I asked the Audi Garage how much GTEE they would give ie Milage...NONE was the ans.....Marvelous you spend 1400 and no gtee of how long it would last.....400 was a no brainer no more hassle

I can certainly understand why people have their DPFs removed, it is way cheaper as Dave says and it does work. However it does make emissions worse overall because there is no filter for the soot despite the engine running more efficiently. Also there was a recent report in one of the papers that the authorities are well aware of the practice and that the MOT is likely to be tightened up in the next year or so to check the level of particulate emissions as well as for NO2.
The main reason that the filter doesn't clear or 'regenerate' is that the engine doesn't get hot enough if the car is mainly used for shortish runs,. It needs a blast down the motorway for 20 minutes or so at least once a week to keep the DPF clear and not everyone does that. The DPF is an engineering 'kludge' and it is the customer who is literally paying the price.

Is there any advantage to having a diesel if all you do is short runs?

None really as the engine never fully warms up and you don't see the mpg benefit until it does. It just costs a lot more to buy and is likely to land you with expensive bills. Diesels are most suited to those who rack up motorway mileage. If you do under 10k per year then a petrol is a no brainer.

No advantage at all Dave....joke is ours didnt do short journies ok yes some days it does fair comment but on the whole it does dual carrigeway and motor way miles as well......the fact of the matter is simple really as Colin has put it ....these so called soot filters are a sheer money making racket to keep the greenies happy.
But does it......all it does is to cause more problems..Why...simple really....you now need specialist chemicals to clean the exhausts up so the metal can be recycled .....more enviromental issues.
Borris Johnson with his darned immision free zones etc have a lot to ans for....next thing we will be back to a horse and cart.....Oh NO  we cant as the green idiots would soon be up in arms about all the horse dung......so we would need a horse particulate filter and lord above if one happened to block up !!!!!!!!

Dave..........where is my protective suit in case the last statement arrives lol

Horses that pull tourist carriages are usually fitted with both nose and backside bags but at least the contents of the latter can be productively used as fertiliser - very organic!
DPFs are poor engineering solutions. Eventually we will have either electric or hydrogen and the cars will drive themselves! The idea of standard battery sizes is a very good one although you would probably need several standard sizes to fit different vehicle sizes.

Thanks, chaps. Looks like my having to buy a petrol Verso instead of the 2.2 diesel which I really wanted was a lucky break. I doubt if either of us will be looking for another car - certainly not in the immediate future - but as/when/if we do there's little chance it would be a diesel and no chance it would be a VW. I've always been told they're unhappy about going past filling stations!

Ah ha Colin fair comment BUT I this day of HSE madness I can soon see a Major flaw as some spotty  nose do gooder will get up on his or her High horse....excuse the pun and turn around and say that Horse manure is a Hazadours waste material and needs a specialist to dispose of the manure as it is Hazardous to the person handling it and to the enviroment.
 The WORLD Is going MAD.

Yet again the topic of Batt powered cars...MMMM lets see....more electricity will need to be produced to charge said vehicle..MORE pollution due to the fact of the power stations having to work harder....more eviromental Issuse.
When the batts on the car end their life...more specialst de pollution will be required...More effect on the environment

Thing is Colin I agree...Heck thats a first !!!!!! Something has to be done,...Biggest joke of all this is a friend of mine works in a main dealer who have these dual cars....Petrol and electric and the biggest complaint of the owners is the rate of degrigation of the tyres....far less Miles /tyre compared to a std petrol or even diesel due to the sheer weight of the car......Hence why they have a short duration......a NO win situation...FIX one problem and low and behold another surfaces.

Hydrogen cars and gas powered same scenario really...whe it goes wrong in come the specialists to get rid of the contaminated parts...more effect on up above....a no win knock on effect

I organised an electric car motor show last year - it was very interesting.

Some dealers were very helpful and supplied cars and staff to demo (BMW, Renault, Mitsubishi & Nissan) - some dealers just supplied cars (Vauxhall/GM) - some dealers couldn't be bothered (most notably VW) even though they had electric demonstrators at their dealership - other dealers were interested but had no demonstrators (Toyota - they only have customer's cars) and other manufacturers wanted to attend but their only demonstrators were elswhere (Tesla)
Other's advertised electric cars but admitted they cannot sell them (Audi)
Most interesting was Citroen & Honda who denied they made electric cars!

I've done a lot of research into the tech and it seems that most of the scare stories are false (old wive's tails) just like when catalytic converters were introduced.
Most of the advances in the last few years are from the software looking after the braking/charging/power delivery - not the battery capacity.
Also, there is a trick that can rejuvinate the batteries back to 95% capacity when their performance starts to drop off after about 8 years driving. This will be part of the dealer service protocol.

The electric cars with the range-extenders (BMW i3 & Chevy Volt) have unlimited range - they just switch to petrol or diesel when the battery is used up which recharges the battery on the move - the fossil fuel motor is not normally connected to the wheels (although the Volt has a very complicated system that can allow the engine to connect to the wheels).

The Hybrids just drop back to fossil fuels when their batteries run down.

For 90% of drivers, an electric car would be more than adequate.
