BUILDING E.F.I.E

[razorback]

does anyone have a plans for building or making an e.f.i.e.doesnt look that hard or complicated.!!!

This is not a plan but some videos you can see here: http://www.youtube.com/watch?v=lw8MtfTx ... re=related.

Good luck. I haven't made one of the HHO systems yet but plan on it in the near future.

thinks papasan. the internet has everything if you can just find it.building an hho system isnt hard at all and is pretty interesting.the gas and oil companies have broke it off in the public for so long anything i can do to take a little of that back.i really like!!!

Can anyone help ?

I am an electronic engineer and see no problem in assembling a circuit that can feed the 2 electrodes.
My problem is that there must be a ressonance frequency that has the best results.
Does anyone know the value ?

Can we use an amplitude modulation or an envelope ? In that case what is the duty cycle and lower frequency ?

[razorback]

kim, i posted the building the e.f.i.e i think the correct frequency varies from vehicle to vehicle or motor to motor but dont hold me to that.i think that is part of tweaking or playing with it.ask ED he seems to know a little about all of this stuff.hang around the forum us shade treeers could an enginer!!!!

Imnot shure what ur talkin about. but fuel injectors are controlled buy the computer,it gets a signal from the o2 and map or mass air flow senser. now that said,the o2 sen. will need voltage added to it( from .1 volts to 1.0volts. that can be done with the right potentiometer and a 1.5volt battery. Now the map sen. will need to have voltage takin awaythe same way. with a potentiometer no battery. NOW ya might have to do some research. if ya have a wide band o2 sen. or a narrow band sen.. The frequency is done buy the computer, ya dont have to worry about it. the o2 sen. sends extra volts to the comp. to richin the mixture,the map sen. will take volts away to richin the mixture. when running HHO ya want the mix. to be as lean as ya can and still run smooth. Ya just play with the potentiometers till ya get it right..hope that can help ya. I now thought about your question. U might be reffering to the rossonance frequency of your electrolyte. Yeah there is such a thing. first, you need a PWM(pulse width modulator)and all can tell ya is ya have to keep playin with it till ya get the freqiency right> every gen. has a different frequency depending on the electrode size and the electrolyte concentration. thats all I know about it

I bought a Book from The USA some time ago . This had circuit diagrams for E.F.I.E

Using a 555 timer this could be done with 556 timer.

The EFI unit in the car reads the oxy sensor hundreds of times per second & if it dont find a correct voltage in a BMW for instance the EFI will switch to limp home mode. In O ther vehicles all sorts of things can happen IE. will switch to auto rich mode not good.
Y need an EFIE for each oxy sensor & some v 8s have 4 most other later cars have 2
The potential is there for causing engine damage.

The unit I built used to plates in a jar & did not make enough gas to run engine. I used baking soda w2hich seems to cause thermal runaway & water boiled.
Whilst muking around the plates inside shorted & yep u guessed it Big Bang which rended me deaf for some time.
Luckily the top blew off the jar cousing no damage.
Now building a nes unit with 8 ss steel plates 160 mm by 200mm this should draw no more than 10 amps.

I am going to do a little promotion but will say many of the other books may be as good but Bob has the efie schematics for two types but more important I think the basics and a good start place that has some very good safety points that I think some are not seeing as important.This gas is explosive the saying it is less than gas or pure hydrogen is like saying one stick of dynamite is less than two or nitro.You bet it is but none of these are NOT DANGEROUS if not used with some safety and respect.Ruining a unit or having temp. deafness is not bad, burns and loss of eye sight is and can occur in a split second with this as can severe burns and fire from the current these use.Sorry if it sounds bitchy or preachy but the last thing needed in this is damages and injuries that can be avoided by some early investment and education and the early tests showed the facts on how fast this gas can get out of control,and the book I bought helped to show me how to avoid them and limit the bad effects when trying to improve them.What I hope to express is buying one of the books or kits with a manual for starting may be a cheap and very saving investment to letting you get to the part where you can develope a better unit that is good and safe.

Easiest way is to buy one...
Try at: http://www.eagle-research.com/products/pfuels.html ($60)
If U stick to the ideea to built one U may use the IC LM 3914. Use a rotary switch between pin 10,11, 12,13, 14, 15 and the base of BC 327 transistor (amplifier), etc. from richest (pin 10) to leanest (pin 15) mix.
U may find all the notes and diagrams at: http://www.better-mileage.com/memberadx.html

thank you alex!. have been in the middle of an ice storm here in the razorback for the past few days.dont have electricity and just got internet back today.will look into the plans.seen some e.f.i.e on ebay for 38 dollars the other day
