Petrol doesn't?

Look at who did the study and what they found in the past. Looking at who does and pays for the study can tell what the motivations for the study are.

I'd rather read the study and their modelling methods for the numbers rather than a news article before running to either defend it or grabbing the pitch fork. But the numbers reported seem rather high, almost alarming (headline grabbing maybe) high. Thus I'm wondering about the stats involved.


Oh, as an aside, why does nobody get worries about dihydrogen monoxide? It's the major component of acid rain! See how facts can be played around with to grab headlines

What's going to happen when most people live to 120.Surely a slice of ham supposedly being worse than smoking was a factor in those deaths also.

Cigarettes are fine again so.

i do wonder how long it will be until we have legal action against the car manufacturers the same way people had against the tobacco industry.. there's a lot of parallels.

I wonder what next year's outrage will be.

Seems to be primarily focused on fine particulates and ground-level ozone. Seems reasonable, that stuff is dangerous. The good news is that as manufacturers turbo the living shit out of small petrol engines and deploy more and more GDI in the quest for ever more efficiency, they'll produce as much of this stuff as diesels ever did and maybe more.

It appears that the (direct injection) petrol engine DPFs don't suffer from the issues diesel DPFs as it's easier to burn off the unburnt petrol particles in DPF. It's the same reason why petrol engines stay cleaner internally compared to their diesel cousins.

Some direct injection turbo petrols have shockingly bad pm 2.5 emissions at cold start and full load.

Right.

Yes, I believe so.

PPFs are located right next to the manifold, so they don't have the issues diesels used to suffer from if they're not driven out of town often enough, etc. To be fair DPF problems are far less frequent than they used to be, too.

Plus you have problems with GDI engines with the cylinder intake valves getting coated in carbon and causing issues at quite low mileages.

Nox emissions are probably the worst for cause of premature death.

R.O.R

So, diesel accounted for 47% of the premature deaths attributed to vehicle exhaust emissions.

Ergo, Diesel is less halmful than other fuels used for the propulsion of vehicles.

Lies, damn lies and statistics.

Can you advise which petrol engines have Diesel Particle Filters?

At an educated guess I'd say he knows full well. And it's particulate, not particle.

Yeah, it was a brain fart from me. I hope it wasn't too traumatic experience for you Mr Salter.

So which petrols actually have GPFs (or whatever the official name is) and wonder when will they actually became mandatory. Some early research at least claims the unburnt particles from petrol are even smaller than the diesel equivalent and so travel further in the body.

Ford, Volkswagen and Hyundai have been at it for a while, anyway. I don't know what the plan is regarding making GPFs mandatory, but word on the street is that they're necessary to keep petrol cars Euro-6 compliant in the real world.

I'll give you half a point for Particle, so:

Jim Salter: 0.5
The Internet: 0

Jaysus, that's being kind...in my defence, Android auto correct made particulate become particle so I will blame technology ...

It's kinda like the Audi owners who own the diesel RS4's - great cars they are
