Selfrunning HHO system with 400 Watts additional output

[grizli]

You don't have to make advanced PWM's to test this engine.  DC is good enough already COP 3 via ICE so if you tune everything correctly it will work from the get go. Even if you are very sloppy and use all of the COP 3 to keep the engine running with nothing left for a load it makes a nice OU water powered heater:)

While Les has covered all the dots and crossed the t's IMO is terribly complex for DIY replication. It looks like a 1980's TV circuit LOL

You can do everything required using an AVR micro which only cost about 15 bucks. Then you add a hall sensor to pin 2, one power fet to pin 5 via a driver and a car ignition coil and you are good to go.

all his logi circuits could stack one one PIC...
or even better FPGA
simple logic scheme is easer to program using vhdl...
but fpga boards are expensive
But we need logic scheme of his scheme, does he provide ?

dont have much XP with mictrocontrolers

Bolt... that would be cool if you brother open sourced the microcontroller code.  I generally open source my microcontroller projects -- but I'm lucky enough to have a day job.

The idea sounds great.  I am sure it will work. Have you decided on a particular genset , or do you think any brand and type will work?

Thanks,

As i said i don't know what he intends to do with the software.  Bear in mind we all need some project $'s income otherwise nothing happens. So many people tell me to build stuff and stop talking so much LOL If i had the money i would build everything i thought had a chance of being useful.

Even Bob Boyce has proprietary software which he will kindly sell you for a small fortune with an NDA. No one says you have to use software you can make your own 555's which is not too hard, or buy Les B's boards professional made might cost 150 bucks who knows?   If it was to be sold it would be a very modest fee and ship the AVR chip but im guessing.

The reason for going HHO is simple. I have a new Genset 2.2Kw 5HP 4 stroke gas engine. I read and learnt enough over the years to see HHO really has some magic to it. When i see the Xmas video i thought what the heck this i KNOW can work. Most important i have a  money back guarantee cos if it doesn't i can sell the genset and the HHO cell and recover most of the outlay. OR keep the stuff, put the cell on the car and keep the genset and run it on anything from Butane, diesel, LPG, HHO mix, gasoline, nat gas etc for emergency use so unlike other projects its not a dead loss. Whatever happens even if i can not loop it the HHO will make it very efficient HHO/Mix

By the way the cell is 21 plate 316L DRYCELL capable of 4-5 LPM on DC approx 1000 watts and 6-7 LPM with HF PWM drive. I run it on reverse osmosis water <4 ppm and just 1 or 2 granules of KOH on HV DC so its like 0.0000000001% KOH

1000 watts will give me 3000 watts within the ICE. Roughly half that 1500-2000 watts will go back as losses and running the cell should leave 1000 watts OU so for the size engine i will be roughly double the German looper IF it works!

I had a LOT of problems with flashbacks, still sorting this out. Things work ok at 1-3 LPM but over that it goes back to the bubbler and its so fking loud i gone deaf and my nerves are shot. LOL

Bolt, are you planning on raising the compression ratio on your motor?

On the Woodpecker video a flashback device is very close to the motor inlet and the HHO is piped straight in.

Also on that video when the HHO is removed the engine continues to run and surge. I suspect there is still some hydrocarbon vapors remaining?

On the Scarecrow videos from 2008 a 3.5 hp generator is shown running on HHO with many flashback booms during start up. On the final and postmortem videos he mentions 6 LPM @ 1000 watts was required for idle and 9 LPM @ 2000 watts was required to run at full speed with a small load. He did not make any timing or compression changes.

I hope you are wearing ear protection in your tests. From watching the available videos it looks like starting the engine on gasoline to get the engine temperature up quickly could make for a smoother transition.

Best of luck,

No its unnecessary  and risk of engine damage.

You wont get rid of carbon vapours its a 4 stroke engine and therefore it is lubricated by oil and will show very tiny amounts in exhaust BUT its not the source of fuel.

if you don't change the timing the engine runs like a pig, back fires, can bend valves and can burn hole in piston. Plus it requires a HUGE amount of gas just to barely run. When properly tuned and blank spark sorted all these issues vanish. Thanks for your input!

why complicated logic.. for ignition you need simple logic and gearing 2:1

Making complicated 3 phase pwm drivers still havent see any youtube prove of that resonant action...
