DPF burn

[Tom D]

Is that not where the problem with JLR Ingenium engine arose? The vehicle would automatically start ramping up for a DPF burn. The user might then switch off the engine and the extra fuel would seep down the bores and dilute the oil.
I like the idea of a warning before any form of process begins.

My understanding is that the extra fuel is injected directly into the DPF itself not into the cylinders, so I dont know how this could happen. Unless the LR was a different design?

That fan running with the vehicle stopped is certainly a feature with diesel VWs and some BMWs with dpf
The IG is much louder than those though.

There are 2 options, either an additional injector into the dpf or just increasing the fuel in the normal injectors.
The latter can dilute the engine oil with diesel, so not the best idea.

Mine seems to do it less these days. (2 years / 20,000 miles.)

Also my observation. 29.000km.

Anyone have diesel buyer's regret?

Hell no! You learn to recognize the very early signs of a DPF cycle starting and can adjust your driving to accommodate it, plus it seems to do it less often as the car gets older and the KMs rise (or maybe I have just got used to it?)

Lower stress longer life engine, goes further per refill, save at the pump, gain on resale. Diesel & lockers the way to go in Oz.

If you are injecting extra fuel through the injectors how do you prevent unwanted acceleration? Isn’t that just the same thing as pressing the loud pedal? Surely that wouldn’t be safe?

Diesel is only an advantage for towing or long distance touring, the added maintenance and complexity makes them inappropriate for short trips and just local driving
I never drive my diesel less than a 20km trip, and I mean never and every now and then drive it like you stole it to clean it out but the Italian tune also applies to petrol and all engines benefit from a good work out

Agreed. I have a 3500kg trailer but only use it with the Ineos once a month or so on average - not really enough to make diesel a no-brainer.

I haven’t driven a petrol one, I’m not sure how they differ in character / performance - can anyone comment?

Fair question.

Throughout the reservation period and virtually up to contract deposit I was going to break from diesel and go to petrol. Diesel seemed to be at the end of development and on the way out, in some markets at least. But then I did my analysis of fuel cost, range, etc. and for my use case (towing and touring) diesel still came out of top. Plus there's the extra 100nm of torque even with IA's gentlemanly tune. So I stayed with diesel and have been a happy hovercraft owner since.

Great idea

Anyone have diesel buyer's regret?

No, I've always had a diesel for the last 5 decades after my vroom vroom teens/ early twenties. I now makes sure my wife has a vroom vroom car when I need to revisit my youth.

I’ve done about 3000 miles in the petrol. It’s ok, i wouldn’t not have one. I just prefer the diesel. The petrol is a bit quicker off the mark but you have to rev it to notice the difference. The diesel has better torque and you do feel that especially when towing. The diesel will hold higher gears better. The diesel just suits my driving style better. And its better on fuel.

My understanding is that the extra fuel is injected at the end of compression stroke/start of the exhaust stroke so the fuel is passed unburned to the DPF.

Google Italian tuneup and modern engines

Anyone figured out how to do a delete? Lots of Duramax and Powerstroke owners here in the States do a delete, eliminating the regen and the need for DEF and get increased HP and torque.

 

[Tom D]

Adblue delete is pretty straightforward, not sure about DPF. The old DPF’s were just filters. The new ones have a lot of sensors which would all require re-programming.

I was recently watching a video for the car trade and apparently old diesels is the new electric for torque hungry heavy vehicles. Diesels are apparently going up in value!! Don’t need to rev the nuts out of it and hence why the economy is slightly better.
