HHO generator on boats, possible?

RDKamikaze,

I have a link to a website for your engine tuning software and hardware. I hope it helps.

I increased my fuel economy by 30%.

I kicked out my dead beat 225 lb carpooler, and don't run the AC when it's below 85-90 degrees. 36-38MPG now!

what do you drive?

My commuter is an Acura integra, best car I've ever owned. The Z71 tahoe is a different story...

You guy's are missing the point here. Don't be two hard on this system. You can not gain 20-30% in fuel mileage by merely changing driving habits. The logic on the computers just don't allow for that regardless of how you tune it.

Example: If you use a tuning system and decrease fuel pulse width at the injectors across all RPM ranges this will decrease the amount of fuel entering the engine for sure and increase fuel mileage. However if you do not have an alternative fuel to replace that loss you will lean your engine out and could cause a failure of the engine or performance issues.

It seems to me what the HHO is doing is replacing the fuel that is lost because the engine is leaned out. How is he leaning out the engine. Not by reprogramming the computer. The o2 sensors are changing that logic for him. They are seeing a rich condition when the HHO starts to come into the engine. Then the computer is switching to a lean command position and decreasing the injectors form about 3ms (Milliseconds) to about .5 or 1.0 milliseconds. Thus allowing less fuel into the engine. This is changing what is called short term fuel trim. The long term fuel trim is gradually adjusted as the short term makes constant changes to the system. The long term fuel trim will adjust over a period of several trips on your vehicle. When you reset that with a scan tool it goes to a zero setting which is not the best setting for your car. The vehicle has to relearn the logic of your driving habits. So in order to change your fuel mileage you have to change your driving habits over several trips and you will still not gain 20-30% because short term trim does not allow for that. There is a lot more to this and I don't have all the time to explain this to you. But I tried to explain it in writing the best way possible.

However in defense of your guys thought it is possible that the HHO is not readable by the o2 sensors and thus this theory would not work.

I travel on the road a lot as you all know for work. So I have been researching this technology for some time now. Also through my OE Auto manufacture relationships I can tell you that this is on its way I just can not say when. There is more to this than you are all thinking. Oil prices are jumping at such a rapid pace for a reason. Don't knock this technology so hard so fast. But I can understand your hesitation.

The biggest problem with it is in an event of an accident. Fuel fumes will be leaking into a hot engine compartment if the system gets broken open. This is not a good situation in a hot engine compartment. The system I have been working on I have been trying to figure out a way for it to auto shut off in the event of an accident. If I can get that figured out with a roll over switch and an impact switch then I up for spending the money to try it out. I have seen the results of a good system and they work. This system he provided a link for appears to be a very nice system.

Not doubting that hydrogen gas could be an alternative fuel source (BMW has proved that and Germany is starting to build a hydrogen infrastructure; I think CA is proposing a hydrogen highway also), but it cannot be done with a mason jar of water and reprogramming. IMHO, anyone selling these systems or the plans to build these systems is scamming people (either knowingly or unknowingly) out of money.

EDIT: Also, for those vehicles with these types of systems installed, I'd be concerned about long term damage to the engine from the reprogramming.

I am with you on this one. They may change the mileage a little but is it enough to justify putting it on my car and taking the risk with it. More research is needed. Right now is the time for these systems and designers of these systems to get the cash though. With the way gas prices are people are looking everywhere for alternative fuels. I may still try it. The system does have a 100% satisfaction or money back guarantee.

Thanks SPBFAN for that explanation. And as far as your question goes for an auto-shutoff, I've read that some people are using an oil pressure switch to control when the device turns on or off. Aparently it's a popular device with drag cars for if they get in an accident, the ignition (or whatever) shuts off so that the fuel doesn't feed a fire. I, however, have not looked into that idea yet. I'm going a traditional method that whenever the engine's on, the kit's on. Good thing most cars stop running when they get in a head-on :P .

And thanks for the link about the MEFI, I'm interested in possibly checking it out. So boats then don't use traditional OBDII for diagnostics/etc.? And remember kids, don't hate something unless you try it first!

[SPBFAN]

That is correct boats do not use the traditional OBDII systems.

However, from Mrs. Chpthril: the car runs longer on it than you do.
