....according to the inventor of the common rail system, Fiats EVP of Powertrain research and technology development. He admitted that the EU wanted low consumption and CO2 so gave the engine designers time to work on other emissions and produce diesel engines with high levels of NOx etc.
Euro V in 2009 and VI in 2104 will require a drastic reduction in particulates (75%). Diesels are already 50% more costly to build than petrol and these standards will make them more expensive still.
It will be cheaper to modify petrol engines to achieve the Euro standards and also give similar torque, better emissions and only a 10% shortfall in consumption compared to diesels.
So basically to achieve the std, diesels will be much more expensive with minimal advantages.
2009 are the timescales for the new petrol engines. The complexity with these petrol engines will be in the software not the hardware.
Personally I have never been a fan of diesels because I always thought that they were stinking cancer causing lumps of environmental trouble (well more so than petrol anyway), so this is excellent news.

I have a Mkiv golf V5 auto engine code AGZ which is suffering from poor idling and hesitation.
I took it to a garage and it kicked up a number of faults - throttle body short to ground, mixture problems, and ecu defect. I was told to change the throttle body and that would cure it all.
After changing the throttle body, the fault was not rectified so i took it to another garage to get the codes cleared, and now the ecu reads no codes however.. the car is still juddering and shaking a lot while stationary and also while taking off.
There is a smell of burning oil from the exhaust and also a lot of fluid (not sure what) is dripping from the exhaust.
I am no car expert but just wish to get down to the bottom of this.
Any help appreciated! Read more
I had problems with my 2001 V5 on idling and misfiring - it was the coil packs on top of the spark plugs - They are renowned for failure on 99 - 02 VAG Vehicles and VW will honour them under warranty as i had them all changed FOC - The car smelt bad as fuel was being pushed thru the exhaust and cat - Hope that helps
Has anyone bettered 71MPG on a Mondeo diesel?
Firstly I have managed to get 71 miles per gallon out of a Mondeo 2 litre diesel with 130BHP as an experiment! Amazing considering the 37 miles from Worthing to home on A27 includes roundabout on the chichester by pass. I drove at steady 56 - 60 MPH and lifted off accelerator when approaching roundabouts and accelerated very very gently as if pressing against an egg! this was done during 9pm - 10pm. I must stress I dont normally drive like this - would drive me mad!

SWMBO takes our TDCi 130 Mondeo from Wales to Manc and back Mon - Fri and she gets 47 - 51mpg depending on delays. Very rare to get any less. The trip comp always reads over by a couple of mpg.
What do you guys think of the Vauxhall's semi-auto gearbox?
Like the one in the Signum 2.2 dti.
Cheers Read more
I really like the semi auto. I've got the 3.2 Vectra. Around town I only use auto. But on motorways it's usually in semi mode. I haven't mastered a non-harsh kickdown on fully auto, but when you are sitting in a line of fast traffic just waiting for the guy ahead to move over it is much easier to sit in 5th then manually change down than use the kick down. Also useful for on-ramps of motorways.
hi all ,having ignored my own best advice not to buy a french car ive bought the missus a renault clio, !just checked over the usual things but i cannot find the power steering reservoir its certainly not where the handbook shows it to be! any ideas the model is a early 2003 1.2 dynamique ,thanks Read more
thanks for your replies it seems the car does inded have a electric system
The engine management light on our Yaris is permanently on. We've had a diagnostic check done by a local garage, who say that the fault code indicates a lean mixture, but they can't find anything wrong.
Looking at other info, it seems to be reasonably common that the oxygen sensor on the Yaris plays up. Would this cause the 'lean burn' fault code to be displayed, where is the sensor and can I check it - or is this a job for a specialist?
Thanks for any help that you can provide! Read more
A neighbour has had a similar problem with a 1.0 Yaris, the dealer seems to simply clear the fault code though not get to the bottom of the problem, frankly they are finding the dealer a pain. I will mention the oxygen sensor point.
Hi
Rather than look up Google, is the speed limit on the big lorries and coaches 56mph, and if that is so, how can they reach 70+ with speed limiters ?? Are speed lomiters fitted to all coaches and large lorries and do the lorries from Europe have speed limiters as a mandatory item?
Thanks Read more
the thing that gets me and i know i am in the frozen north but as each year goes on you find that the foreign driver has more respect on our roads
when they pass me in my old truck and i flash them its safe to pull in with their drawbar trailers or their extra lond rigids they say thanks, the english registereds on the whole dont
if they pull up and ask for directions in their eu trucks they might not speaka english but they sure know how to say tanka the english dont, i have to say thankyou to them as they go back to their trucks and they turn and give me a glazed look

Didn't go in a tux though. Could only manage a three piecer and a top hat.
I saw the thread about highest mileage cars, but what about highest mileage motorbikes.
Highest I know is the 185,000 miles BMW motorbike in the Ride Magazine this week.
Any other nominations? Read more
If I remember correctly, the MZ racing engines were rotary valved, an entirely different beast to the piston ported engines of the mundane road bikes. BTW, the rotary valve was a Scott invention, dating back to 1912.

Re that huge 2-stroke diesel ship engine - supercharged 2-stroke 'uniflow' diesel engines did enjoy some popularity in commercial vehicles and in locomotives.
Foden offered their FD and FE 2 strokes up until the 70's, though most of their lorries had Gardner engines. Commer used their unusual 3 cylinder opposed-piston TS3 engine while some Bedford TMs had Detroit Diesel 2-stokes.
The famous Deltic diesel loco took its name from the two Napier Deltic 18-cylinder, 36-piston, 3-crankshaft opposed piston supercharged 2-stroke engines - surely one of the most unusual engine designs ever!
The Class 59 and 60 freight locos common today have GM 2-strokes too.
