Idea for HHO addon in a Diesel vehicle
Hello
I've built and have been experimenting with HHO application to my 90 model diesel hilux truck (non-electronic i.e., no sensors). I've studied the diesel fuel pump a bit and I think I've come up with an idea that is worth trying. The idea is to inject or mix streams of HHO bubbles into the diesel fuel being supplied to the engine ideally inside the diesel pump with some small modifications. Previously I've been feeding HHO to the engine through its air intake. I have had most appreciable results in mileage improvement if the amp draw remains low (10+) with this method.
However with the debates on engine timing + HHO and seeing advantages only in cruise modes on roads without traffic signals for obvious reasons (diesel vehicle fuel pump doesn't have a governor to reduce fuel supply on additional rpm through burning HHO), I now plan to get a used diesel pump, modify it, and test the above mentioned idea to add HHO to it instead of the air intake. I'm posting this to see if experienced people have any suggestions or things (good or bad) that I might have overlooked in theory.
Thanks for reading.

Hey Buck,
All I can say is that it must be fate.. I was thinking the same thing a while back, and then had one of those forehead slap moments. Injector pump pressure and injector pop pressure are carefully matched because they are critical for timing. When air gets in your lines it compresses, taking a few extra microseconds to reach pop pressure, and throwing your timing off. OK then, you say.. I can just advance my timing a tiny bit to compensate for that! Fine- now how can I ensure that I get consistently the same amount of HHO into the stream at all times so my timing is not fluctuating? HHhhmmm... It was at this point that I thought to myself- I think I'll just continue to do it the regular way... Haha!

A few thoughts to go with your thoughts on injecting hho bubbles...airation in diesel fuel is BAD BAD BAD... 2000 psi is enough to ignite hho in the right enviroment... BAD BAD BAD... and finally there is more stuff in hho gas than just hydrogen and oxygen, the combination of the additional molecules creates a gummy residue that plugs up ports and eats away at pintle seats etc. BAD BAD BAD... These are some of the initial findings of our experiments down this road, however if you have any different results PLEASE let me know what you did.. thanks.

As an ex-diesel Mechanic, I suggest against it. The injection pump is a highly calibrated component, and the introduction of a gas (Not liquid) will definitely cause erratic idle/run if not produce a "NO RUN condition. These pumps need to be primed out of bubbles. (As you may have witnessed after running out of gas)
Why? because liquids don't compress like gases do, and the diesel injectors require sometimes as high as 1700PSI, and as low as 400 psi-depending on the system. Each diesel injector has a 'Pintle' and nozzle which atomize, vaporize the fuel.
(Also sounds dangerous) Stick with where you're at, and enjoy current gains ;-)

because I think if you can run on all common rail diesel engines to solve the problem of pilot injeccion burning hho almost all, if it is true that the hho makes autoignition at 580 degrees Celsius, but just do not know if it becomes inflamed pressurized.
is true that hydrogen can be compressed to 100 parts to 1 (the hho do not know), so the hho by injecting a needle into the tube of diesel fuel in the hose low pressure, will be very small bubbles as they pass through the pump high pressure will be almost microscopic.
is interesting because if this works with a small amount of hho large increases can be achieved.
happy new year

This will just not work at all. In either a common rail or straight Bosch pump. Besides the problems mentioned by Bio, hHHOEfe and Joe W which covered just about every possibility. When HHO is not diluted with air it is explosive and does explode under pressure and heat especially good quality HHO. It will also easily ignite with the temperature of the injector before the injector opens in a running engine causing a serious problem and damage to the injector and possibly damaging the engine. Unless the HHO is very very little and of no use anyway you are just asking for trouble. If the amount of HHO is small enough to not cause a problem in the pump and injector then it will not help in the combustion process enough to be of any value.

I think it's certain that you have all the reason in this.
I was just thinking how to solve the problem of the injection pilot in the common rail diesel as my car.
hho yesterday after I put the turbo and intercooler and noticed the engine more torque and more cheerful, the execution is different from normal pre-turbo, and it seems the tank bubbler and good resistance to pressure, otherwise the cambiare for deposits pvc.
but according to my impressions after the turbo is better and more wax as possible to the intake manifold

Hello, Buck!
If not give up to that idea I think you may try something but not mix the oxyhydrogen as gas with diesel since the gas will cause the troubles explained by others who replied to your post.
I suggest to try ionization of water and mix the alkaline water with diesel. As high pH as better mixture you may get ( and freezing point depression also)
Add less than 0.5 % borax as lubricant in that water and mixture will work - at least - in old type pumps without problems.
If your ionized will produce gases direct it to intake manifold, as usual.
