It makes sence. You're already rotating the alternator. May as well put a small load on it. If the battery is charged, you may as well use that available energy to charge the fuel by converting water to hydrogen. It's not like you can stop your alternator from rotating. When you are idling your car, or cruising down hill, you could have your engine off, but you don't. It's doing senceless work alot of the time you're driving. You could say it's wasted rotational force. It makes sence to harness this into HHO.

The principal behind HHO is to harness wasted energy into fuel. This is why it's not a replacement, but it's a way to put better use to the fuel.

I do believe that it would require tuning to be effective.

 

I dont think it would. On most ecus anyway.

 

^^ thats my point exactly.

Like I said, we aren't looking for free energy or anything, just simply the use of wasted energy. There is a minimum amount of energy the alt. is putting out at any given rpm. If it's not used it turns into heat in the system. I know for a fact thats it's never putting out 0 amps. So what happens when the system doesn't need any more juice while your cruising down the highway?

radu I would how ever like to see the video's you mentioned. I have studied the topic at hand. I had a couple years of electrical engineering classes, but thats been 5 years ago now.

 

Oh yeah, I'm sure there is some energy wasted. I'm just saying the alt doesn't put out 90 amps all the time. In any case, it takes on the order 1-2 kW to spin the alternator even at full load.. BUT you would at most be creating HHO at about 1 kW rate (kW "power" as in the power you would get by burning the HHO), even if electrolysis would be 100% efficient. That doesn't sound like a whole lot of fuel..

Supercow, here are those lectures, this mad scientist guy is the bomb, he does all sorts of dangerous experiments right there in the classroom lol but also explains very well (IMO still worth to look at even if you already know the stuff).

edit: about the belt/electric fan, probably because you can control its rpms. Belt driven = always proportional to engine speed. Electric = whatever speed it spins at when you apply 12-14V; plus it can run only when it's needed (here is probably the biggest energy saving).

 

Frozen, glad to see you've tried to experiment with it. I have only bought a couple components for it so far. One of the biggest issues is dealing with the ECU with a system like this. You need to be able to lean out the fuel, and there are a few simple products built for a conversion like this that you can put in. Here is one: http://easywatercar.com/mfg2/index.php?q=m...p;user=fuelteck

There is also a TON of related products here. Check them all out.

interesting.

 

I'm pretty sure that most have clutches that turn off the fan... Maybe older cars didn't.

 

^ Oh, don't know what to tell you then. Here's an interesting writeup on that: http://www.aaroncake.net/rx-7/efanmyth.htm

 

Now I know our ECUs are tricky but on most it SHOULD be able to lean itself out because there would be unburnt fuel exiting.

 

^ HHO helps in preventing detonation, so to get the most out of it, you'd want AFRs leaner than what the stock ECU tries to provide.
