The egr cooler is designed to cool normal exhaust gas temperature but it's unlikely going to be able to reduce the highly raised EGT to the same level at regen. The regen process doesn't spew out soot as it's burnt so it 'spews' out the product of that combustion process and anyway emissions from diesel engines (particulates and NOX) are almost solely a problem in urban environments as far as air quality is concerned due to the traffic density and proximity to more people so you are right it doesn't matter so much in the countryside. 2012 TDV8 Vogue (L322) |

This explains quite a bit

Hahaha, that doesn't explain anything, it's a theory from 1983 and a patent of some snake-oil from 2011 - neither of which are in current use.

It simply explains the basic chemical process inside a DPF for regeneration and is the same basic science I remember being taught way back at school. If that was ‘theory’ and snake oil can you update me with the current science for carbon combustion / DPF regeneration i.e what does it now produce (sorry ‘spew’) if it’s not CO2 and at what temperature does this happen? 2012 TDV8 Vogue (L322) |

But it clearly says 600C in your article as well!! 2018 SE SDV8 4.4 Byron Blue |

Yes 600 deg c is the temp you need to burn carbon cleanly as referenced by many articles. My comment you are quoting was in reference to Phoenix who seems to think it’s out dated or snake oil ( hint - the meaning is in th that followed)

Your thoughts being that driving gently to not stress the drivetrain on a 150k mile car is bad ? Or is it the more frequent oil changes? Or avoiding short urban trips and only putting on motorway miles ? - or have I missed something? 2012 TDV8 Vogue (L322) |

Surely the parts of the drivetrain are designed for such use. If they break then mend them.

And if I wanted to prolong it's life and not have to spend money on or worry about replacing drivetrain parts ? Also the L322 feels just right wafting gently along. I'm not talking about driving like a slow road nuisance either as it gets up to speed very briskly without needing the 2nd turbo. Surly this is the very essence of the L322 - effortlessness progress in any situation 2012 TDV8 Vogue (L322) |
