California to ban selling new gas-powered cars by 2035

Yes water injection will reduce both NOx, soot and increase power and fuel milage.
DEF reduces all of the above.

DPF trucks burn much cleaner than the soot-belching trucks. I'd compare it to a carbureted car and EFI with catalytic conversion car. You smell when you're behind an old truck or car.

And no credible evidence was posted to support the mileage and other claims. I wouldn't be surprised if he has his pickup "chipped" to smoke.

DPF trucks are an illusion. They still put out plenty of soot it's just the soot they do make is 1 to 2 nano meter so you can't see it.

My carburetor suburban smells like fire crackers as its set up for lean idle and lean burn.
You can't chip a diesel that isn't computer controlled. Are you really that dumb?

We can only spoon feed you so much, at some point you need to lean how to do your own searches.

"DPF trucks are an illusion"? Yet I'm supposedly dumb because I don't know your truck?

Those water injection links have nothing to do with DPF.

Your personal attacks weaken your arguments and expose your immaturity.

The first computer controlled diesel pickup truck class engine didn't come out till the mid 1990s and "chipping it" wouldn't make them smoke.
The first diesel truck that could be "chipped" to make them smoke didnt come out around 1999 or 2000. So it's not just my truck. It's every truck from that time period plus another decade and then some. So you just don't know anything about diesel engines.

DPF stands for "diesel particulate filter".
You really don't under stand diesel engines beyond "put a chip in them and they smoke". Since you can't seem to understand how water injection and soot tie in together and you can't find it Google searching. I'm pretty sure that 2012 ecomodder thread spelled it all out, I think there were even epa studies linked, if the links haven gone dead, some thermodynamic process theory, entropy discussion, ect.
I'm highly immature are you just now figuring that out?

Sometimes it seems quite pointless how mainstream automakers and suppliers went the DEF route instead of resorting to water injection. Even requiring some alcohol to be added in order to prevent freezing and leading to an easier switch from liquid to vapour phase at the intake charge.

Water injection alone may not have been able to lower the NOx and soot to insanely all but non existent levels the EPA was demanding.
But with the added complexity of DPF and DEF systems they are targeted for removal and deleting.
If the EPA would have gone with something not as offensive to the wallet as water injection there would probably be a lot more trucks rolling around with the emissions systems fully intact.
Main problem with water injection is everything freezes and bursts. The DEF never really fully freezes it turns into a slush mix and as far as I can tell it doesn't bust lines, pumps solenoids and other controls.

Sure it could eventually not be the ultimate answer to the NOx issue, for which using it alongside EGR could fare better. Well, considering how it could decrease the usage of Diesel fuel for a given output as it leads to a more complete burn, a soot decrease could be easily expected under normal circumstances.

Water injection had been used on fighter aircraft which were flown under much more critical temperature and pressure differences, so it doesn't seem too unlikely to become manageable on a car or a truck. Remember it had alcohol added in order to prevent freezing, and most carburettor de-icing fluids used in aviation to this day are based on some alcohol too.

Yeah but with air planes they are running so anti icing systems are active. Plus I thought they used water methanol for the cooling of the water and the alcohol for octain boost of the methanol.

[Piotrsko]

The anti icing systems are rubber boots that inflate to rupture the ice bond so it slides off in the slipstream. It also doesn't work on frost. Preflight deice cleans off the wing so stall speed doesn't go above the calculated balanced takeoff speed before you run out of runway.
