Particulate filter

Basically if black smoke is being kicked out it doesn't have a DPF, meaning it either wasn't manufactured with one or the owner has removed it!

The reason for your lack of black soot/smoke/plume is answered in the same sentence with your description of your driving.
Your point implying that having black smoke means you don't have a DPF is to put it politely, not correct.

So in actual reality it is not as per your post "spit all the soot" (hence my post), the only ones allowed to be released are the ones you see (which will be getting to a smaller size owing to tighter restrictions in Euro standards), the ones above this via the process of regeneration will be changed into CO2.

And here is lovely picture to make it easier...



Additionally this means the emissions even from a car during regeneration of a car with DPF are not the same as a car without a DPF.

Furthermore to add to your post the reasons for the particulate release the same can be said for petrols with direct injection, the CO2 output is lower, efficiency higher everything higher bar one issue they release particulates which according to the WHO following various studies (which also implies the EU now with it's stance on filtering particulates) has seen particulates (mainly from diesels) put into one of the highest categories of carcinogen.

I never said it was an amazing invention merely not a "stupid development" either, which would seek to imply that it was and is not entirely perfect (nor was the catalytic converter originally), but in so doing with having it in place it has the benefit of removing the potential dangers particulates pose (especially of the smaller kind) in damaging human health.



Ever thought people might not know what a DPF is? Additionally if you actually think about it the term soot filter is a perfect term as it implies it captures and then "filters" the soot that would be otherwise released into the atmosphere. It neither implies or expressly tells you about what is actually exiting the exhaust.

There is too much to go at and dismantle in all the above and there are elements that are so ridiculous, any retort by me will fall on deaf ears.
So I'll leave you to happily have your posh sieve replaced every 75k miles and I'll have a party using the money I save by being DPF free.

Oh really even though I replied to all of yours? Clearly you are the one that does not understand them or is simply unwilling to try and understand them with generic wide sweeping statements.

Elements that are so ridiculous how come on?

Who said I even have a diesel? Your assumptions about me are very wrong.
In fact I don't even own a Volvo personally now. I have never owned a DPF equipped diesel, but can see the advantage they bring about.

Anyhow clearly any understanding anyone put in front of you about the DPF and the issues particulates can cause to human health will fall on death ears nor do you appear to care about the future world any younger relatives or even children you have live in.

Ninja, your lengthy response to all of my points did nothing to change my opinion and I doubt anything I say will change yours, so I'll save my keyboard from a pointless task and happily agree to disagree.
I enjoyed the debate though

[Ninja59]

What was there to even debate about you made wide sweeping inaccurate statements about how a DPF works.

Very few of my posts actually highlighted my actual opinion on the DPF itself beyond that it does some reasonable good for human health.

[cheshired5]

Yeah, I'm just hearing noise now.
You're not related to my ex wife are you?
Sheesh. Enough already.

[meddyliol]

Thanks for all of your informative answers. I didn't give thanks before because I forgot where I had posted it. Sorry.

I missed this little gem from your edited comment.
It seems you're not so against sweeping statements as to refrain from using them yourself.
I'm all for having a difference of opinion on automotive technology but to suggest that I don't care for my children's future or that of wider society simply simply because I don't like a car part is the ramblings of an idiot.
You don't even have a DPF yourself!
Or does caring for the environment only extend to just agreeing with the principals of DPF's not actually putting your money where your mouth is and using one?
You sir are a hypocrite and a prize tool.
Quite an achievement.

I thought you were not going to reply?

No not the ramblings of an idiot in fact quite true if you hate the DPF who's defined purpose is to remove particulates it implies exactly that, so to then take personal attacks is totally uncalled for.

I did not have a DPF on my diesel as it was BEFORE the WHO and EU had made their decisions on particulates BEING carcinogens, and also in a period when Volvo kept changing specifications. And as my current car is petrol and not direct injection it is furthermore irrelevant on particulates and DPF.

As I stated :

"In fact I don't even own a Volvo personally now. I have never owned a DPF equipped diesel, but can see the advantage they bring about."

This seeks to imply that I would have no issues with owning a DPF equipped car, the fact I have never owned one personally does not mean I would not take issue with it, which I would not (which you would or your posts would imply you would) neither would it be to say I don't have a DPF equipped vehicle in my family (which I do).

Additionally, I think you should remove some of those personal attacks as at no point did I actually deny I would own a DPF equipped diesel under the correct conditions, I currently drive a petrol as it is is more suitable for the miles I do (generally short trips unsuitable for a DPF vehicle and not enough miles to justify the extra cost of diesel fuel) and the type of vehicle I want to drive (and no I will just state this again my current car is a petrol).

I did sort of warn you above with a question that I did not own a diesel personally currently....

[cheshired5]

I'm removing nothing.
