Smokey Diesels - why is it...?

The duty cycle of the vehicle is completely irrelevant
Really? I was under the impression that if you did enough short trips even the regen cycle wouldn't work and you'd have to take it to a garage..?

The regen cycle cannot occur if the vehicle never enters a driving mode that support the regen cycle (e.g 10 minutes steady state at normal engine operating temps) - So you are right. The fix is to spend a few minutes on a dual carriageway - much cheaper than a trip to the garage where some unscrupulous person may convince you part with some of your hard earned

I know that some site vehicles like fork lifts and dumpers have a DPF that has cartridges that are removed each night and cleaned off. A DPF on a car that could be removed and cleaned out this way would be pretty handy for people who do short trips obliviously and then have to limp to a garage. £30 instead of £800.

On the honda accord forum there are a couple of threads about taking off DPFs and cleaning them with a high pressure washer. It seems to work. I just made sure my diesel didn't have one when I bought it and keep it well maintained so it doesn't smoke.
Problems DPF's, EGR's, turbo's etc... the savings on fuel petrol vs diesel can soon disappear.
On the Accord forum the "common faults" for petrol has 169 replies at the moment and diesel has 3360 replies!!

Remember diesels generally do more miles and there are more of them around.
The guy who said buy a small petrol basically has it right, by euro6 I should any small to mid cars will generally be petrol. The diesels will be hugely expensive, not good on a light duty cycle and plenty complicated.

Only if you get the problems. I've just done almost 40k trouble free miles. Oh, tell a lie, I had a fault with the airbag wiring the other day.
40k miles cost maybe £4,100 if you assume an average of £1.20/l over the last two ish years. A petrol would have cost maybe £5,300 at 38mpg (a guess for a petrol Passat) and £1.15/l

You are absolutely right - with no problems you are going to save a lot of money on fuel petrol vs diesel. I ran a citroen ZX TD for over 100K with not a single problem and 40k on my current merc without a problem. The issue is that it's more of a risk now with how complex modern diesels can be. If they go wrong you can have some big bills that soon cancel out fuel savings.

My mondeo doesn't produce soot and it is more than worn in now, probably because it's rarely running at low enough revs to collect.
Another example;
Of the Land Rovers at work the TD5's are smokier than the new TDCi, not so much because of the common-rail technology progression or age, but the the heater tecnology progression, the older ones spend a lot more time idleing to get the cab at least as warm as outside, whilst the newer TDCi is warm before we get to the road, straight from start-up.Posted 7 months ago # -

That's a bad idea. Just MTFU and drive the thing, it's better for the engine and will warm up far quicker. Your newer car will have an electric heater in it.

diesels can operate hotter than petrol engines, since they don't pre-detonate like petrols do at high operating temps (pinking, iirc). bigger temp drop for the heat cycle means better inherent efficiency.
Diesels can knock, though direct injection has helped prevent that (by ensuring fuel is only present when combustion is desired, unlike older injection methods).
One of the other reasons D's are more efficient is they don't have a throttle, immidiately offering up a greater efficiency especially around idle and lower revs.

It's mostly the other guys that leave theirs to warm up, we're all nice and cosy in chainsaw trousers in ours.
Do have quite an issue with the inside of the screens frosting over in winter, used de-icer inside once and won't be doing that again, so heat it will be.Posted 7 months ago #
