The press regularly announce that particulates cause respiratory problems and are killing people by the thousands. Usually by subtle implication, they blame hydrocarbon fuelled car engines. This is all very misleading in itself and forgets particulates from other sources and, for transport, from tyres. These exceed those from engines, especially traditional gasoline engines. Worse still, they go up rapidly with increasing vehicle weight and shear at the road surface. EVs weigh much more than an equivalent gasoline vehicle and have huge torque from zero speed. Yet the green vehicle movement seem to happily brush those particulates under the carpet.

I may be prejudiced as I've spent most of my working life in the oil and gas industry, but facts remain facts. We can agree that climate change is happening and, like many emissions into the atmosphere, isn't something that we want. However, steps to improve the situation should be exactly that, effective ways of improving things, not a means to make cash, a political name, or look good for 5 minutes.

Because they can make money selling more electricity, the fact that there won't be enough in the future doesn't matter at the present. They're arrogant enough to believe they can deal with it when the time comes, if they've even thought about it yet.

It's the same for the health care system, no one is looking for a cure, if they did that, the drug companies wouldn't really be needed after a while, nor would all these hospitals.
You would go to the hospital for a broken arm, nothing more.
You go to the hospital with a disease and it's treated like palliative care, no cure, they only cure the symptoms, but the disease carries on.
Finding a cure for cancer _ please give, that's a bunch of BS ! No one is looking for a cure !

They can't have cheap and even free hydrogen that's too efficient _ no money in it.
Money before humanity, that's the way it is, I've given up on things in that respect, and unfortunately, our planet is already gone past the point of no return from that way of thinking.

I know all about the problems with direct injection, one of which are the injectors getting all sooted up with carbon from combustion.
I still say that all that mess should not be there, at least to that extent just because the injector isn't cleaning things off.
The inlet valves on my Bentley sure don't look like that.
It's not fuel injected, but it has lots of vacuum to pull any oil past the guides.
With everything up to spec and with new stem seals in place, there isn't the mess I see in your photo.
I would say that engine has too much oil getting past the guides, and at least it needs the stem seals replaced, or maybe it doesn't have any, does it ?

Perhaps the car gets driven very hard and I could see that happening, but still, it's pretty bad.
This was a monitored test vehicle in normal service. As launched prior to the VAG group LP injector fix. Your Bentley is not DI & enjoys a fuel wash of the entire inlet system beyond the Carb. If run on decent gas it has a cleaning additive in it. If not Techron then likely at least the Lubrizol system. They are not all equal. Our additive division Oronite designed Techron. BP worked with labs to design theirs etc. Many of the others just buy in the Lubrizol additive which does a reasonable job.
