Hello guys I'm new here I have a good idea I think yall will love it. This post will be long, so I apologize….
I first want to give my story then my ideas. I ran across HHO videos on youtube thinking it was b.s.. This all changed when I saw a truck running on pure hydrogen at a car show. They started her up on gasoline and switched over to hydrogen, no tuning, just idling with enough calculated hydrogen. Hooked. This changed the way I though about the subject. I am finishing up my biochemistry degree and have been working on engines for a long time and been custom tuning for a year or two. One of my vehicles is a supercharged 4.3L truck. The supercharger broke and I'm having a small coolant leak in the intake manifold so work is to be done this spring/summer. I'm thinking of selling a few nitrous kits laying around and stashing the supercharger for now and starting this HHO deal.
What attracts me to HHO - alternative hydrogen (obviously), cheap fuel (water/electrolyte/electricity), and the ability to run it in the bed of my pickup off my alternator, creating hydrogen as it is running = no compressed hydrogen tanks ready to kill me and everyone else. Just a fun boom if things go wrong, maybe lose an eye but not die. But of course yall are into these things too.
This is what I'm thinking, I'll need help with recommendations for all this HHO kit business. What I want to do is run x amount of HHO from a serious kit, not a silly one...a real deal. I'll learn all the tricks and bells and whistles from yall. I'm going to invest in a hoffman apparatus and measure the exact amount of hydrogen per given time being made from the HHO kit (have slight paranoia and some ADD in there I should be studying for a biosynthesis test in two days but I’ll make an A anyway) Convert this volume/time into the energy equivalent of gasoline in gph. I work in an organic chemistry lab so I may have access to equipment that could separate and measure the hydrogen without buying my own junk. Already have a fuel pressure gauge installed in the truck and an air fuel ratio gauge, would need a fuel flow gauge in gph to convert energy equivalents.
I will take the gph of a given average fuel flow at an rpm, say my cruising rpm on the freeway maybe 2000-2200. Subtract from this the amount of hydrogen energy (in terms of gasoline gal/hr) that the HHO kit will generate per given time. I would then find how much fuel pressure decrease from stock (stock is 58-59psi currently) would be needed to allow for the HHO hydrogen energy to compensate and 'take over' the absence of gasoline. Using HPtuners I can tune against the stoichiometric air fuel ratio of gasoline at 14.7, so the computer is not adding fuel to the mixture and effectively disabling the problem of AFR enrichment. I will need to modify the fuel lines, and install an adjustable fuel pressure regulator (FPR) on the line before my fuel pressure gauge. It will make a small loop. I have used fuel solenoids from nitrous kits to block the fuel flow on one side of the fuel loop, forcing it via dash mounted switch through the fuel pressure regulator whose pressure drop will be set based on previous said calculations...(when the solenoid is off -free flow- the fuel will automatically go through it as you would drive normally, it will allow for more fuel pressure when open than the regulator side of the loop). If the solenoid ever breaks?who cares it will just add more fuel and it'll be richer = nothing breaks. If it sticks, I may have problems… but it won’t. Before this solenoid is switched on, I would need to turn on and apply the HHO gas kit deal which I will have on operation by switches (not on all the time). Those fuel pressure drop calculations from before will err on the rich side of AFR. Hit cruising rpm on the highway, flip the fuel solenoid on -block fuel & drop pressure through FPR- and the engine should stutter and try to stall, then come back running through a narrow cruising rpm band. The idea here is to get the amount of fuel exact so I am not wasting either gasoline or hydrogen. This would be very hard to tune with variable rpms, and especially at idle or above peak cylinder pressure or when pressures rise 2500rpm+ (I do this stuff).
Depending on how much hydrogen is being shoved in and how much gas is cut, it could be very profitable in terms of gas mileage, it costs 80$/tank per week. My mileage is 80% highway. If I could cut that even 20% on the highway, save 12 bucks a week. If I could cut that to 50% (which means my fuel pressure would need to be around 28 psi :eek: on the HHO) then I could save 35 bucks a week and the kit might start paying for itself. If I could cut it even more, which then I get into trouble with detonation closer to peak cylinder pressure, then I could pay for a tank of gas every two weeks. Which would be freaking awesome and insane to say the least :cool: Even if I see a few mpg increase, at least the $ wasn't going to nitrous and go fast candy.
Btw my truck's MAF is disabled until inspection time rolls around each year, and I tune my own MAP sensor parameters so those trickeries won't work, I'll have to tune myself. I think yall also have fancy throttle/tps type progressive controllers, will look into those, flashback arrestor, pwm, and all the goodies. Thanks for reading suggestions please!! Give me insight ya'll have done this before. I will have lots of questions once the time comes! I’m stoked…
