Diesel Particles burn off systems causing the odd tractor fire?

[Spanner_Man]

Is this on all their stage v tractors?

Unsure of the smaller farmall/T5 models but certainly Maxxum/T6 upwards

 

[Pilatus]

Ours was blown down that morning

Hope that tells the sceptics of this thread something

There are lots of reasons why things fail. Some days our luck runs better vegan others.

Absolutely correct. The system should only need to regen maybe 3 or 4 times between engine services and not for overly long. The dealer should also carry out a forced regen before every engine oil change to ensure working regens are kept to a minimum. Engine oil life is effected due to the diesel for the regen being injected at the bottom of the exhaust stroke

If this is correct why have they extended the oil change intervals on thd larger stage v tractors?

I suspect this is down to newer and better synthetic oils and bigger filters these days. You could probably run the best modern oils for several years in an old tractor with no EGR or regen. Maybe just swap the filter halfway through.

There's no if involved, this is how it it is. The oil hasn't changed, just the filtration. It's a sales gimmick keeps your cost of ownership per hour down. Every manufacturer extending service intervals so one can't be left behind. They rely on you the owner to read the manuals and your dealer too know what they are doing

Like vw and 30,000 mile oil changes. All it means is your running dirty oil with more crap in it round your engine for longer periods but the manufacturer say its ok.
Very similar to grease, oil is cheaper than steel.

The fumes given off these tractor fires will be much more damaging to the environment than the exhaust particulates which were saved by the dpf filters that started the fire

Is that a scientific fact?
Which fumes are these? In what quantity?

What is the total particulates saved in UK vs fumes from burnt tractors?

Advertised cost of ownership.

Well was kind of a light hearted observation really!
Burning tyres/plastic diesel tanks, diesel/lubricating oil & grease , hydraulic hoses Aircon gas paint etc all cause the nasty black smoke & fumes which are released into the atmosphere! Then the machine needs to be replaced prematurely with replacement, which is another unnecessary carbon footprint, so has the dpf filter really done any good? I think they definitely improved air quality in inner city's on cars vans wagons etc. Although they have also been the cause of many many road going diesel engine runaways resulting ultimately inevitable costly blowups, again causing the carbon footprint of building a replacement engine, +pollution of oil when the conrod fires through the side of the block! Making you wonder do they have a place in the often dusty combustible agricultural environment, where fire is an obvious risk working in the conditions an agricultural machine was originally designed to work in before DPfs were enforced onto manufacturers by the governing bodies! Is it an economical balance between the two I wouldn't know, time will perhaps tell

When we ran a fleet of 828 fendts we never allowed anyone to do a regen in the shed, always parked outdoors for the process.
Never had any fires but very easy to see how this could start one.
Exhaust manifold and turbine housing were cherry red during the regen cycle.

Thats alot of post injection

I remember hearing when DPFs were first introduced about the option to remove them for cleaning off the machine. That might have been more for machines working in especially hazardous environments though, such as mining combustible materials.

Changing the fuel injection timing to super heat the exhaust seemed like a bodge to me, but probably cheaper for manufacturers to build than having a separate burner at the DPF.

It is. 7th injector is by far the best option, as JD now do.

I know it’s not ag but my 335d BMW nearly torched itself last week.
DPF blocked up, then heated up and cracked a hole in itself, it was glowing red when I lifted bonnet.
BMW want £2400 for a new DPF, it’s getting a £160 straight pipe instead.

Darkside developments are especially good for software

It’ll be getting a slight remap to adjust to the freer flow but no more than 350bhp.
More interested in economy at the moment tbh and it’s bad enough going around damp roundabouts as it is.

Well you'll need the regen strategies turning off obviously.

Good point thanks

DPFs are bull anyway. Collect the large soot particles and then burn them to make them smaller. I can't for the life of me see how this is a win for the environment.
