Thread: Diesel Particulate Filter for Disc 4 HSE SDV6

There are 8000 people living per square KM in sydney.
and workshops,wharehouses and other industries locations that may require paticulate fiters on vehicles and some stationary engines.

cant rember what the LPG emisions are when used in confined locations but a diesel would be better for a street broom or generator.

the trucks we have need to be parked for about 15 minutes in neutral-if you touch the clutch etc it will delay the burn.

we had a discusion about this..a cat grader has been unhappy for some time-it was incorrectly fitted with a safety exhaust pipe that blocked and pressure fed exhaust into the air cleaner.with the correct pipe fitted the computor was having kittens to the dude fixed it.

the discusion was why does our new machinery not have to comply.on the engine it shows it passes american off road emision specs.
not a number i recognise like sae or dot.

Nothing new about it...

I knew about it not long after I joined up the first time when it was identified as a carcenogenic. That was back in the late 90's it was revisited in the mid 90's after Diesel Cats came in and diesel exhaust was downgraded.

DPF has been around now for about 3 years and if my suspicions are right its going to result in the diesel exuast of EURO 5 vehicles being listed as "mostly harmless" and I'm going to have to go sit through another ass load of testings so I'm covered by Comcare for my employers negligence in exposing me to a deadly carcinogenic ( along side asbestos, paint, radiation, noise, vibration but sadly not idiots)

I like to fit it all into the catagory of

"give me enough data points and selective flexability and I'll prove anything you want"

stone age people died from black lung as did women 80 yrs ago from tending cooking fires.

my dads now 10yrs older than my grandfathers in his late 70's-a heavy smoker in dusty chicken sheds farming and logging- had skin cancer since he was 30yr.

his health issue is blood pressure and stress .

properganda at this moment is partculates at a smaller size that need study with regaudes health risks.

its like if you keep study of things then you find something--------

I'm concerned about the health implications and would like to know if its possible to order a DPF from the dealers to have it supplied and installed?

Can anyone shed some light on this?

Yes.

In the light of the Forum comments, pick the nearest one or more...

* Land Rover did not design it to have one, in Australia.
* Your research before purchase was non-existant.
* Your research before purchase was not competent.
* A DPR was not mandatory at date of manufacture. (Did you change to CFLs when they first became available, or when you had no choice ?)
* Other......

Certain regulatory authorities will need to approve such a modification/addition to comply with 'roadworthiness' and safety.

If you do have a non-standard DPF fitted, understand that you may be liable for any adverse event(s) caused by said DPF fitment. - Any hurt, injury, fire etc that can be shown to be associated with it in possible way or degree....


You will need to consult your insurance company.

My car runs clean, and has never even the slightest puff of fume behind it. The exhaust has a very different smell to diesels I'm used to, quite innocuous.

I've had mine 2.5 years and I've had two regens (as in warning light comes on) and yet I drove in heavy traffic every single working day. The only reason I got a regen was the fact that I travelled through an area with miles of roadworks and there had been a prange. Everytime I felt I should turn off the engine, the traffic would inch a few feet forward (plus it was very hot outside). I was standing still or moving at less than 5kph for well over an hour. I doubt most owners would ever have their car regenarate, if driven in normal to heavy traffic.

When the car did regen....I assume it did it when the car was rolling at a decend rate of knots, as this is the owner manuals recommended way of cleaning the filter and getting rid of the warning light. At a guess, I'd say the car doesn't regen when the light comes on, only after you meet the regen parameter...but as I said, I'm guessing there. Maybe it's only at a certain high level of blockage that the light comes on and the car is constantly doing minor regens.....dunno.

As far as the actual regen activity is concerned, to get the light to go out.......you don't notice a thing.....no smoke, no noise, no obvious loss of performance. If it wasn't for the light on the dash, you wouldn't know anything had occured. On both occasions the light went out within minutes of normal driving.....not 20 or 30.

What's other D4 owner's experiences, are they the same as mine?

Cheers,

Kev.

I don't have any D4 DPF experience, but I do with some Audi/VW diesels.

The burn you are experiencing above isn't the standard regen. It sounds more like a necessary burn to clear a mostly blocked filter on a low speed vehicle.
The VAG DPF's periodically burn clean during normal open-road driving based on a distance/time setting buried deep in the ECU, this is imperceptible to the driver unless you have the instantaneous fuel economy readout up.
At steady road speed the fuel consumption will increase by about 2 litres/100km for a few km as the engine retards injection timing and does post-injection to fire flames down the exhaust and into the DPF to burn it clean.

They do this with no lights, no extra noises etc. But if you pull over when it's started you will apparently feel the extra exhaust heat and even smell it.

If a DPF gets too far blocked, it won't burn clean and has to be replaced. If it gets poisoned it'll block up and need replaced. Eventually the filter and it's sensors will need replaced anyway. Timeframes seem to vary but two audis here which are 3-4 years old have had sensors replaced each but the filters still going okay.

Thanks mate,

That's the sort of info I was looking for.

How long does the standard regen normally take....seconds, minutes?

Cheers,

Kev.
