Thanks for the link, interesting, I'll work out the maths when I'm a bit more bored. It makes a good point about the number of passengers, 400+ as opposed to maybe just one but I have been on several trans-Atlantic flights that have been half full or less.

Less people on the plane saves a good deal of fuel on take off. At cruising speed at a great height, the plane doesn't burn quite so much per person, as the air is thin, and the plane has to overcome less friction.
Although the fuel burned for person mile in a plane is not as bad as you might expect, the emissions are released in a very damaging part of the atmosphere, high up, so the calculation is not a straightforward one.
They do work on diesel , although I didn’t really look into that side of it, it’s not only just for spark engines.
It is well reported that it will help clean up a Diesel engine.
Don’t ask how I know. But there’s plenty oil in the ground for us pertolheads it will be regulation that takes the ICE down.
As turbo says it will still be needed in other forms.
Hydrogen and HHO are 2 different beasts.HHO burns very efficiently and burns quick. Once set off by diesel burn, off it goes.
Also because HHO is unstable if compressed it works too, so what actually sets it off?
As I have Said before I don’t know. But will one day try.
There are lots of pitfalls and loads of folks will tell you it can’t be done.
I have read loads on both sides, and still believe.
Did you ever think you would carry a phone in your pocket and actually be able to charge it from the sun

Sorry i didn't mean for storage, i meant when it enters the diesel cylinder.
I started writing a reply but I just confused myself with air fuel ratios.
To simplify, you're adding HHO at the intake manifold, this increasing the amount of oxygen drawn into the cylinder while also introducing hydrogen.
That sounds like it should make for a bigger bang but also sounds like you could add more diesel? Diesels run lean normally, to prevent smoking, but if you're increasing the percentage of oxygen then it figures you can increase the diesel without getting smoke?
How fast does hydrogen burn? In comparison to diesel in the cylinder?
Am i just talking utter rhubarb?

Worked for the Hindenburg!
Honestly I was expecting one of the older guard too come in and say that ( as he did before)
I also believe you had to have a man walk in front with a red flag when ICE was first allowed on the road. Because they might be dangerous in some way?
And people still blow up theirs houses because of gas leaks?
A bin bag full of HHO would scare you. But the amounts produced in an HHO cell is going to be more like a poof/bang.
This is why special tanks needed for storage of H2.
Bit like LPG I suppose.

I don't have a house. As it happens, my boat is gas free, everything runs off diesel.
My post was in fact a joke, HHO is probably fairly safe in a road vehicle. However, I would question the cost benefits in a Bowler. You would save much more fuel just by changing driving style. And masses more by getting a more economical vehicle for the road, and using the Bowler when needed.
Firstly you are not talking rhubarb and I don’t know it all about this.
Let me try (as best my knowledge goes)
H2 is pure hydrogen which needs oxygen added to burn, this can be ran as in an LPG system.
HHO is H2 +O so will burn on its own. You are not getting any Oxygen for the diesel side.
HHO will encourage a more complete burn in any engine thus reducing bad things out the back.(smoke?)
It will (so they say) help clean out carbon deposits and so help with the efficiency of the engine.
They also run quieter.
No need to increase the amount of fuel (diesel petrol) In fact some say need to tweek O2 sensors or fuel maps otherwise the ECUs will try and add fuel (as I stated earlier it’s difficult to do with HHO)
Hope that makes sense.

I know that
And would agree the OP might be better with a second car.
It’s not the diesel you have to worry about, it’s all those new fangled solar panels you have on you roof, are sure their safe
New things are good it’s just sometimes, old guard can’t admit (not calling you old by the way)

My brain is quite slow sometimes... But..
If the HHO 'takes care of itself' then you can take it out of the equation. That means what is left is a richer fuel ratio.
I think i just confused myself again. I'm now thinking about completeness of burn before the exhaust valve opens.
I'm also pondering the initial combustion. Diesel in an oxygen rich gas, under compression
There's a reason folks use nitrous and not pure oxygen, the nitrogen is important. Thermally expanding (not burning) and pushing the piston down.
If you introduce HHO then you're reducing the amount of nitrogen in the equation, while making potentially a better combustion, but the result will be less power over all. That's why racers use nitrous - a bigger, hotter burn to heat up all the nitrogen making it expand and produce lots of extra power

So isn't this a similar trick to introducing tiny amounts of LPG into the combustion chamber to make the diesel burn more completely?
Yes but. As you stated diesels run lean. It also burns extra HC that are usually unburnt.
HHO burns quicker, including some of what the diesel compression burn doesn’t.
Now N2O is totally different subject as it introduces more “burnable air” so you can add more fuel. (I am really digging my brain cells here). Forget about piston movement please.
N2O is actually breathable, we all like it
so it is only the “air part” of the fuel triangle although a very powerfull part. Why do you think hospitals use it (laughing gas)Less power overall can happen, as I stated earlier maybe tweaks needed, note maybe.
The amount that is introduced burns itself and what’s not burnt from the diesel/petrol burn. Hence less HC.
I am trying my best here from the grey cells, and if anybody wants to correct any of my statements please feel free.
I just happened to do a lot of reading on the subject years ago.
@kermit_rr you really are testing my grey matter tonight
not that, that is a bad thing.J
