gas but no savings....... HELP

[mrmechanical]

Hi all, new to this but learning quickly. Anyway to cut a long story short, got my generator working great . Making great gas, amps are good (20 when at operating temp), I have a carburetted engine (1987 Nissan), so in theory I should see something, but my gas mileage is the same, and I don't understand why. I'm sure I'm doing something wrong, or forgot to do something. If anyone has any ideas, or questions as to what I have or haven't done feel free to ask

You need to trick the oxygen sensors. Wrap your O2 sensors with tin foil and then secure them with zip ties that can withstand 140 degrees of heat. That is the cheapest way to do it. Or you can search on the net for plug-ins that trick the 02 sensor.

actually,if you have a carb,you will prob have to change the jets in your carb,if not,i dont see how you mpg would change any at all,but your performance should increase even so.

i dont think you have any 02 sensors...do you?
whopper is correct, you just get a lil more power for how much you push on your pedal, example:
if you normally have to push down half throttle for 9 sec. to get to 40 mph
maybe with the hydrogen you only have to give it a third of the throttle for 9 sec. and less throttle for keeping going too, thats prolly whats going on, if you had more hydrogen itd be easier to tell. on carburated engines cant you turn down the idleing easily from some kind of screw? thats what i did on my friends porshe a couple years ago... it was an old ass porshe...air cooled, but not hydrogen related, it was because the car changed altitude when it was shipped to wisconsin

Hydrogen is a very light gas.

Make sure you're near a heavy sort of vacuum like the start of the throttle body or the mouth of the carb.
Where are you injecting the gas exactly?
What's your gas output in lpm (liter per minute)?

If you have O2 sensor, it is partially responsible too. Look around the net and you'll see the solution that will suit your need and make. Also check out newsgroups, especially ones like:

They might have specific hints for your cars O2 since messing with it's output is done to INCREASE the amount of gasoline for performance reasons too.

Try leaning out your idle a bit. That is the time when the least amount of gas necessary is being furnished, and if you have good output from HHO, it should be able to provide at least 50% of the fuel demand at idle.
Seems like a tiny amount of all driving time, but it adds up.

I think that's the time where any pinging would be minimized too.

Hydrogen ignites faster than gasoline and present engine timings are done so that the piston is still compressing the gasoline/air mixture to the top of it's stroke when the spark plug fires.

Hydrogen explodes fast enough that it will realize it's full potential while the piston is still traveling up and rob the engine of energy (and can damage it severely as higher RPMs), so it's a good idea to know how much HHO you're injecting into the intake to see if you might have to start adjusting your timing towards TDC (top dead center).

Search and read in the archives here and youtube. I'm sure there's lots more good info out there.
Use it to verify what I've told you and learn the other helpful hints I don't know.
