Back when #2 was $5 a gallon I had bought a Hydrogen generator and installed a system on my truck.
As soon as I turned it on with the Split Shot injectors I could hear detonation. I did pull my chip for a while and it didn't audibly detonate w/ the stock split shot programming but then it was horribly slow.
Anyways, I quickly turned off the system and I just figured that the Hydrogen was all burning during the pilot shot of fuel and this was not a good thing. I noticed on Black Cloud Diesel's website they mentioned the same thing and suggested that the Hydrogen systems are not recommended for the split shot trucks.
Fast forward 6 months. So I get my big single shot BDs re-installed and start playing w/ them. They run clean when I have boost but as heat and humidity in Central TX increases over a few days they start to smoke too much for me during low boost situations. So I try turning on the Hydrogen again w/ good results. (completely against Jody's desires by the way) I'd say the smoke was reduced 75% under all driving situations.
I don't hear any detonation. It doesn't sound extra smooth the way it can when you run Propane due to the reduction in diesel delay. It does sound a little more crisp however. A hair more crackle to it at higher RPMs. I assume quicker combustion is occuring. I have tried to resist giving it the goose but it runs so nice it's tempting. I did briefly run it up to 45 # of boost and it was running great w/ no smoke at all by the time I hit 20# of boost.
I also ran a test to try and get an idea of the amount of hydrogen production. I turned on the Hydrogen system and stuck my hydrogen feed tube that usually runs into my intake into a plastic cup filled w/ soapy water. Soapy bubbles rose out and I lit them w/ a lighter and they certainly burned! But the volume was not much. Maybe one 2-3" diameter bubble every 1.5 seconds.
So I figure the amount of hydrogen is too little to began burning on it's own due to high cylinder temps the way Propane is apt to do. It likely just helps burn the diesel I have quite thouroughly.
So for any of the programmers or experts out there who have managed to not yet completely fall asleep during my Charles-esque in length description what are your opinions? And better yet, has anyone actually looked at what is occurring in the cylinder to peak CPs
Thanks so much for contributing.
