Mazda diesels are infamous for problems with the diesel emissions systems leading to on some occasions huge repair costs.

Even Toyota have had problems with their Yaris diesels so what chance does any other manufacturer stand?

But I imagine late Mazda petrols and other makes will be fitted with a petrol particulate filter and issues will soon be surfacing or already have?

Hardly surprising, they stopped selling them in 2016 thus the newest is 7 years old.

If it worries you don't buy a car fitted with one.

Possibly, I’ll certainly be avoiding anything with any sort of particulate filter for as long as possible. They’ve utterly ruined the previous reputation for durability the diesel engine generally had.

But something had to be done to stop then chucking out cacogenic particulates. Think of the future generations.

According to a What Car article, VAG, Merc and Ford were early adapters but,

"The technology has been introduced to most new petrol models since 2018 to meet EU6c requirements"

Reading the article, it does seem PPF's are way less troublesome than DPF's though.

I am, we use SWMBO’s electric Nissan Leaf for the bulk of our driving. I’ll probably inherit it when she upgrades, assuming it proves reliable.

The engineering solutions fitted to cars to achieve the clean air that we all wish for seem deeply flawed or impossible to achieve without introducing massive maintenance costs that the second or third owner is likely to inherit once out of warranty.

Being in the parts trade I'm pretty sure I've never been asked for a ppf?

Sold plenty of dpf's however along with gallons of snake oil claiming to clean them, all down to people buying a diesel when there use pattern is clearly wrong.

Fundamentally the Mazda 2.2 isn't a bad engine when it's made to work long and hard.

This doesn't appear to make much sense, Future generations arent going to be significantly impacted by current carcinogenic particle emissions, apart from possibly having prematurely dead grandparents, an ambiguous effect.

Acquired cancer is not known to be generally inherited, though I suppose there might be exceptions involving mutations in germ cells.

(I'd have to look that up, but any such effect from carcinogenic particle inhalation would likely be too tiny to detect.)

Future generations are likely to be severely impacted by CO2 emissions, in which context the diesel does better than the petrol engine, and might be severely impacted by large scale adoption of nuclear power as part of an electric economy.

This doesn't appear to make much sense,

Its simple. If we had continued to pollute our cites etc with particulates from ICE vehicles the health of our future generations would have been affected. And its not just cancers we are talking about, particulates cause respiratory problems as well. Whilst the introduction of particulate filters has gone some way to helping it only a partial solution.

I agree that before DPF's diesels had a better reputation but the 2 diesels with DPF's that we owned and did not cover more than 8,000 miles a year in and used in mixed conditions simply got on with regens which we learned to recognise happening. To avoid causing the DPF's issues we avoided (where possible) stopping driving before the regen had completed and in the almost 6 years we had the BMW and the 5 years we had the Kia we never had a single DPF related issue.

Most DPF issues were caused by the ignorance of the owners and/or salesmen not making owners aware that a diesel was not appropriate for their use.

Motoring Which describes the Mazda CX5 Diesel as a Best Buy with mention of the good diesel engine.

Similarly the Ford Eco Tech and the Peugeot Pure tech reviews get no warning about impending doom in the motoring press.

Its only forums like HJ who live in the real world !

If "future generations" refers to generations as yet unborn (and it does) then current particulate emissions can have no effect on them.

Simple as that.

So its not necessary or appropriate, in this context, to "Think of the future generations".

It IS appropriate to "Think of the current generations", which includes current children.

This doesn't apply to CO2 emissions which have long term effects.

If "future generations" refers to generations as yet unborn (and it does) then current particulate emissions can have no effect on them.

It can if the parents of those currently unborn die prematurely due to pollution.

Try telling them it has not affected them when they are at their parents funeral.

You two can bat this back and forth without reaching a conclusion. It is probably a toss-up, similar to the question of whether smoking 40 a day for 50 years will kill someone before the age of 85.

Exhaust particulates are washed out of the air quite quickly by rain, so the present hot dry spell will not be helping the atmosphere. But CO2 sticks around a lot longer - it has been growing steadily for many decades.

No,

It isn't a "toss up"

To oversimplify slightly, Its simple

I am right

Skidpan is wrong.

Simple as that.

The Demonising of Diesel and the miserable failure of climate mitigation shows quite clearly where our priorities lie, not with "future generations" but very firmly with our own short term interests.

And that is probably how things will remain. It's part of the human condition to cater for the short term first (after all, the long-term predictions may be wrong). And if anything, the present culture of worshipping the rights of the individual will not help ?

Except when the long term predictions become the short term realities, as seems to be happening currently.

But then its a bit late

I mentioned that this was an ambiguous effect in the context of premature death of grandparents,. I didn't feel it necessary to spell out where the ambiguity lay, .or that the same applies to parents.

The support burden on future generations (individually or as society as a whole) of an ageing population is a repetitively expressed concern, indeed almost a cliche of our times, but, unlike the CO2 burden we are currently offloading on them, there are no proposed solutions I'm aware of.

Unfortunately I wont be able to turn up to funerals to be thanked for running Skywing The Slayer for so long, because Chinese air pollution (or something else) will have done for me by then.

Have to point out that I never said anything about a "toss up", read the previous post and you will see that was Andrew-T.

So you edilthgow are wrong.

Thought I was replying to AT.

I also thought quoting the post I was replying to made this very clear

But apparently I was wrong.

It happens.
