This video is an offshute of the earlier car engine conversions of spark plug electrolysis in Georgia . It is assumed, the same method was applied to the lawn mower engine here. The plastic tub holds the electromagnet putting field over plug wire to retard the timing , for use with hydrogen gas. Also in there is the dual coils relay for use with ONLY the interior 2 inductors and center diode. It is believed the vacuum sealed relay forms RADIANT ENERGY that benefits the firings. RE not escape because of no air, and follows wiring to plug. The 110v AC to Dc inverter (hidden in cement block rear hole )  sends 7 amps peak current as 2.6 amps average DC current through zero ohm Champion spark plug just AFTER the high volts pulse. The Magnetron trigger is aided by an added on, put together Patent TESLA small circuit that increases the Primary back emf , so as the secondary side gives way higher ignition volts, about 24KV as needed. Lawn mower ignition needs to be boosted up as equal to auto ignition coils. Uneven engine runnings during 2005-2008, was allieviated when adding in EGR for the Nitrogen content. Also the Inverter box should be changed to pure sine wave type,- not modified square wave type as commonly used, as not good with inductive electrical loads. The Briggs engine was self running on the ring , dual alternators under flywheel. The small flashlight battery pack for the ignition modification only used milliamps. The large car battery was only there for the starter motor, then completely disconnected. Low power conversion, but 18HP shown as working. The green Inverter in video background was broken and just left in video. That's why man said inverter WAS NOT USED in the 2 successful 2008 You Tube videos of S1R9A9M9.

Long time back I made failed sketches regarding diodes protection of the 400watt inverter that was used on cars conversions in Georgia back at that time. It BUGGED me that the system still was working after 3000 miles on chevy car. My recent clipboard drawing with erasable ink pen finally showed promise.  I knew that somewhat similar set up had to be on the Briggs engine. Here goes, — The starter position of car switch provides 12v to ignition coils. The plug gets full 12kv high voltage. When key running on position , there is a ballast resistor that puts 6volts worth of high volts to ignition coil.  Now it's 6kv firings. The Georgia schematic on the web forum Waterfuel1978 @ yahoo.com showed only 4 possible diodes  following the Inverter box. That's about 3200V protection. Two in the bridge rectifier1kv + 1KV and 2 in the circuit as 600v each.  The bridge rectifier was not shown. Remember , the technicians in shop did all the work, Nathren father was non tech person. He only looked over the shoulders, and reported work done on the web forum. As resistors add up in series to input resistance, spark gap voltages in series also add up to beginning high volts. The Chevy distributor with spinning ROTOR provides the first of 2 spark gaps. Loss of 3KV. So now, there is about 3, 200volts protection against 3000volts ignition final voltage.

The second thing going on is that the spark plug AIR gap of high resistance is way reduced , due to the water solution. Less high volts is needed to fire plug. The project viability has gotten way higher.

The main energy power supply as DC is required to be minimum 100v or higher. Some guys used Inverter 220vAC . This is because the volts input to water solution is WAY REDUCED by 10 TIMES.  220 becomes 22. 110v becomes 11volts. DC low efficiency electrolysis requires minimum 3 volts. (You can't use 12v going to 1.2volts through water solution) Current gets reduced way down , due to tiny electrodes specific area of plug tips. (Not large plates in water)

Zero ohms resistance Champion / Autolite spark plugs pass the needed DC current as 2.8A average or 7 Peak Amps on scope. The circuit resistance by OHMS LAW requires volts divided by certain resistance to get the 2.8A.  The circuit diodes reduce the 110v down, then the 10 to 1 reduction , so as the Relay resistance in series was total 1.2ohms at about 10volts DC. Close enough as 8A, to make Hydrogen gas and electrified water vapor pressure.

The system had been enhanced by the radiant energy provided inside the relay by the high volts against the diode cathode inbetween the 2 inductors. The R.E. Follows the wires to spark plug. One set double coils relay per cylinder. That's why they were called the "Magic relays".

I refer you to the old documents you read long ago about the Engineer             
Who had US Patent on the added diode circuit to regular CDI ignition booster. The main discharge capacitor has LEFT OVER volts charge after firing Primary, so as the balance 50v 1ufd cap discharges balance through microwave blocking diode to high volts side. The loud SNAP at spark plug was aided by what he called the front side Capacitor.  You can also use his Back Side Capacitor as high volts PF capacitor across the spark plug. The PF gets quick first charged by ignition, then when ignition then fires plug, the added energy makes extra snap energy , as called PLASMA SPARK.

I believe that the Briggs engine could have used the other, Tesla added circuit as ignition voltage booster, but would have needed way more diodes protection, that greatly reduced down the final needed low volts, to get the required amps.
I did recent bench tests regarding back side capacitors , liked the 20-30KV Blue ceramic capacitor as 1000PF- .01uf, - good snap noise. This design added is dangerous , and can put you on the floor. This simple method to get Plasma Spark that THEN allows the main amps to go through spark plugs. A plastic tube with insulated wire is necessary to safely discharge that capacitor before putting in the fingers.

As per my previous messages, I found out there are 3 types of Inverter boxes - square wave, modified square wave, and Pure Sine Wave types. Georgia people used the wrong one and always had uneven engines running, but they did run. Electrical loads that include 1.75mh +1.75mh, Inductors must have pure sine wave energy.

To further isolate the main Inverter box from shorting, on the Briggs engine, the return line at bottom of plug goes directly back to the Inverter terminal. The  battery neg, is not connected to engine casting. You don't want 2 grounds together, inverter secondary DC neg and battery neg.  The starter motor has the battery neg only. . The starter is electrically insulated from engine using nylon plastic bolts and washers. Lots of guys long time back had burned out their expensive Inverters with shorts. (neg to neg) Of course you can use 2 separate batteries.

vintage car radios had solid state vibrators for the power supply to generate hv and frequency. https://www.vintagecarradio.com/accessories/repro-radios/accessories/repro-radios/repro-radio-vibrator-for-most-models/
Old time inverter.  Even earlier the Ford model T trembler coil also generates steady freq.

Man! Thats cool stuff 
Unbelievable what they knew in those days....

The Hefferlin manuscript was regarding steam to Hydrogen engine using high frequency. Back in those days , 1921-late 1940's, high frequency + high volts was only related to the famous high voltage Tesla coil. The extreme vibrations antagonized the molecules to separate very easily in heated chamber. The modern Patent reference I cited was to show that a particular frequency was relied on to make efficient hydrogen fuel gases from steam. Samuel Leach, 1970's  Patents 4148701, 4113589,4247379,4272345   - special composite coating in chamber inside emits frequency when heated, extracts Hydrogen from steam.  Newsweek April 19, 11976, Sam Leach's box pg78.     
Tesla coils can be made/adjusted for many frequencies output. The secondary tube is made first and accurately adjusted. The Primary is then tuned to to that one. Early models were spark gap and capacitor type. Nowdays they can be solid state firings of secondary. Back issue Electronics magazines have articles.

The S1R9A9M9 Georgia engines conversions had used only AUTOLITE brand spark plugs with solid COPPER ROD center. There are many part numbers, but most are with internal resistor of about 4000 ohms. The AUTOLITE 295 is ZERO ohms, non resistor type,  and not iridium type, as recently tested by me. This validates the Georgia electrical circuit as being able to pass the 7 Peak AMPS Current through spark plugs.


My Horvath Patent power Supply as beefed up CDI for powering the separate water cell is just about done. Fans being hooked up to keep China Inverter transistors / heatsink cooled. The end transformer TR2 with battery cable needs to be wound. 30 turns #12 and 3 turns #6. Photo to be sent later. I have been ordering parts for the aquarium box cell, as fittings gauges, special switches, etc.

 Time to change the wall calander! Happy Holidays!
