A successful conversion of a small mower engine to run on water in carburetor, is based on several actions at the same time. The ignition type has to be inductive ignition, not capacitor discharge ignition. This means the amps flowing through the spark plug must be from a DC power supply. The speed of CDI is too fast for proper contact with water molecules to MAKE hydrogen gas and water vapor pressure. The current has to be low, so as the tiny tips of plugs don't get burned out. The best setting was called 6-7 amps DC pulse according to S1R9A9M9. Nathren , in 2005-2012 worked with the 2 technicians in the shop for testing building alternate energy related set ups. Ignition primary wires can be switched around to get the opposite output polarity high volts. One man was his son who had the same name. They both contributed tech data on the previous website that is now closed down. So you have either positive or negative high voltage, diodes facing proper direction, proper resistance in circuit based on OHMS Laws, time delay lines added for way late retarded timing to -34 degrees, required magnetic field that travels down to plug tips ,and 6-7 amps DC current. The high volts pulse is NOT good enough to provide a proper PLASMA PATH for the expected current to pass through plugs. What is used is an added small circuit that has a SMALL capacitor charged with about 200v DC against a blocking 15kv FAST diode , hooked to the capacitor output. The initial high V. pulse out, in split second ,sees a different path rather than the effort for the spark gap. It presses against the ON diode that abruptly shuts off , compressing the high volts against the diode , that then reverses back and fires spark plug.. It takes with it, the small cap discharge very fast, providing energy path for the waiting main current. The delay line is provided by wire turns over the plug wiring, and also an inductor coil of about 1.5Millihenry in the high volts line. The Briggs mower has preset non adjustable timing at TDC. The Mag field stretches the firing time out to -34 degrees along with the the extra L coil.(see data on the S1R9A9M9 triple wire coils assembly that has several purposes same time). The MAIN power supply is to be called ISOLATED grounds, as is done with an Inverter box with a transformer separate secondary side with output single diode for about 45 volts pulsing half wave DC output. No filter capacitor. Output has to go through a safety series bank of 15kv total protection diodes . This short length series diode bank rests vertically on horizontal 80mm 12v fan .3amp, with see through plastic shroud. The heat released is blown upwards away from the diodes. Either FR607 with dual set screws European type wire terminal connectors, or fast flat plastic DTV32F plastic damper diodes on narrow aluminum heat sink. The inverter isolation separates the battery ground with the output power ground. The miniature added P.S. is a 150 watt 20khz open board inverter with fast bridge rectifier you add on. Two output.wires are soldered to the appropriate terminals for 200v AC. .The high volts sees the 2 diodes in the bridge through the ON 15Kv diode. It wants to bypass the plug gap effort, by going different route seeking the opposite high V polarity terminal. But the microwave diode stops it, and reverses back to plug. This technique is US Patented, US8555867B2 and has this output diode added to the capacitor that is on a regular type CDI . The left over energy, from firing Primary of ignition coil , goes through high volts diode along and goes with with the high voltage that fires plug. (Just firing ignition does not allow extra main energy current to pass to plugs. ) The small board power has to have enough watts and current to keep recharging the minimum 45uf 400v cap in between firings. The MAIN extra energy comes from the Inverter power supply. The ignition voltage has to be extended in time of milliseconds for more contact with the water. The CDI type deals with microseconds. The 15KV diode is said to also release RADIANT ENERGY that travels down to the combustion chamber. Tesla worked with this and had written about other special circuits for that purpose. See data on Tesla Hair Pin circuit that has extra spark gap and 2 capacitors output that releases radiant Energy. The earlier Georgia S1R9A9M9 car conversions all used special dual coils relay per cylinder, and they were IN VACUUM. I just assumed that the radiant energy if provided, was enclosed and not lost in the air, so as it would travel with the circuit all the way to spark plugs. They had diode, coil, diode, coil , diode to output. The high volts came in after the 2nd diode. Th L coil charge from inverter was in front of the 2nd diode. They called them the "Magic Relays'. The required magnetic field came from them and traveled down the wire. (Also, a North + South neodymium magnetic ring type magnet fits over a steel spark plug and field is also there at the tips in combustion chamber-just another idea.
S1R9A9M9 from 2008, used 6-7 amps through zero ohms spark plug, to produce water vapor pressure along with electrolysis Hydrogen at spark plug in engine. His v8 car was on low power , about -34 degrees late timing, but was on 18 miles per gallon only mineral water, for about 3000 miles, until locked up in security garage. His Briggs 18HP mower engine was on 10 amps through spark plug of 125 ohms. He used cross leakage inductance high volts from the triple magnetic coils assembly to raise up the low volts to over 1300v , so as the 10 amps would go through spark plug. Ohms law 10a X 125 ohm = about 1300v required. (The shop technicians did not know certain plugs can have the resistor removed, for a racing zero ohms spark plug.) Too many amps burns out the tiny electrodes of spark plugs. They said to use 6-7 amps as best. The capacitor discharges are too fast. Needs time for contact of water with the current discharge. That's why inductive ignition is required - not CDI. S1R9A9M9 Cars and mower engine conversions to water, all used Inductive ignition with 3 terminal autotransformer. This is my bench project for a while now. See my other data messages on Energy Science Forum and Free Energy forum.
Aaron's special circuit had to do with adding it to water spark plug design, so as there is a proper/ better plasma path for spark plug electrodes. Very low value capacitance, but about 200volts DC charge. This is separate circuit than the major amps. It has to come from a bridge rectification so as there is a ground through 2 of the diodes, so as the 15kv high voltage transfer diode can reference that path, before it slams shut and hi V reverses back to the spark plug. This is Patented. This was CDI type type ignition primary and secondary transformer, , but parts could be added to your design without being CDI, just to get this better plasma path.
The Water Fuel Cell company by Meyer, had the best Hydrogen generator . 3000% efficiency. PLAIN ONLY Water cell was a capacitor and was in resonance with the( 2) L inductor coils with pulsing DC > than 1500v.. The added inductors after pulser transformer, can perform back EMF for a much higher voltage to cell. The inductors were resistance wire- not copper. . His Patent on this was commonly now called VOLTROLYSIS. The VW car drove around first on a water cell, then later changed to complicated water injectors per cylinder with circuit boards. Sensor circuit added to keep water level same for first water cell, for same resonant frequency of the water capacitor. This is for ionized HHO free fuel which has more energy content - not common H2 + O2.
Way back in time, Aaron showed a diagram that the microwave diode hooked to only 2 series diodes to ground would give the same effect for spark plasma.. This may be an error. His US Patent has a charged capacitor releasing EXISTING left over residual energy through a high voltage diode to make larger spark. His other data talks about high volts pressing against an ON diode that shuts off and reversing back to spark plug. It seems to me that a diode needs a small voltage on it to be in an ON STATE, and a MUCH higher volts just to get the higher spark blast.?
My original assumption was that Nathren (S1R9A9M9) also used one set of dual coils relays on the Briggs MOWER engine, since the sets also worked on the earlier car conversions.Then there is also OHMS law for circuit total resistance required for the 10amps flow through the 125 ohm spark plug. I have his original statements from the website about extra parts included in plastic tub on side of mower engine, with the S1R triple coils and an Inductor from a relay of about 1.5Millihenry. He would have also included accessory spark gap, diodes, and a 400v distributor CONDENSER, --- as a play on words, as he said "no capacitor was used". The charged condenser with diode output would also add EFFECT to the firing spark plug, as long as there was somewhere a ground point in behind diode. His final report was not forthcoming, and we are left to figure it out on our own work benches. Does any one know if Aaron's special circuit would work with coil inductor on voltage, or if it would "hold" a charge like a Cap does?
The twin conductor extension cord was hooked to exact ground under spark plug as part of the "Y" with other end hooked to plastic tub. The male plug was probably bridged. This was either a LONG required ground return line back to the Batt/ Alternator, or an actual ground for the tub circuit. There were 3 wires entering tub with 2 output wires. The high and low volts was ajoint inside the tub. (Yes-- the ignition volts was on the Battery and alternator as a hazzard.) The Briggs engine started on the battery, then battery completely disconnected, and circuit then ran on the under flywheel dual alternators with the revolving 12 MAGNETS. See his mower engine again, self running on water in carb. S1R9A9M9 You tube videos 1+2.
Nathren's schematic diagram for water powered circuit for auto 8 cylinders shows certain facing diodes, so that the negative firing 1978 HEI ignition coil would not fire spark plugs. Ignition bypasses plugs and goes to ground through 2 diodes. The old style coil in distributor cap type could have had the 2 primary wires switched around , so,as having POSITIVE high voltage output, which then would fire the plugs. The low voltage power in was halfwave pulsing DC , so as no diodes of a Bridge Rectifier there for a source to ground for a special separate diode discharge.
The 2 technicians in the Georgia work shop did not tell Nathren everything. He even believed the car spark plugs with 10 flowing amps were original copper Autolite type with 6000 ohms resistance. As him being a non technical person, I can see now why a detailed work booklet was not going to be available to the public.
On the other hand, the regular type ignition coils are what's called autotransformer. That means there are 3 terminals-, not 4. In general, the common autotransformer type has one end of primary hooked to one end of secondary. The engines normally have positive ground, meaning the POSITIVE high voltage jumps upward from ground to center spark plug electrode. The ratio of internal wire turns is set up that way. If input + and - terminals are switched around, the output would be positive high voltage at top of plug, but at a greatly reduced voltage . Therefore, it is possible, on the High Energy Ignition coil for the 1978 Chevy V8 engine with coil mounted in top of distributor cap, to be switched over to be able to get high voltage positive. The HEI (4 ) terminals are plus 12v positive, timing , safety spikes ground, and output center terminal facing the rotor. Nathren's web tech forum did not tell people everything. Some of the work by the 2 technicians in the Georgia shop was not told to Nathren. He may not have known of this ignition change that was done, based on the original schematic THAT SHOWS only positive and positive being used on engine. He didn't even know what spark plugs or modified ones were mounted on the ElCamino car based on the ohms resistance. There seems to be more to this old story from 2005-2012. The Inverter box on car was insulated from ground and the alternator charged both batteries.. After extensive driving period at 18MPG water only, he removed old El Camino gas tank and replaced it with welded steel box with exhaust drippings saved. The vent allowed some hot vapor release. This allowed the Nitrogen embedded content water to be reused at HIGHER efficiency, allowing less frequent water fillings, and the last statement was then ,about 300MPG. The wife ordered her car locked up in a security garage. The electrical circuit was based on using a 110v AC output Inverter, - changed to half wave pulsing about 45vDC, special design switching obsolete relays per cylinder, and exterior mounting of about 10 diodes of 600v each. Internal diode was between the 2 inductor coils. When the technicians left the shop due to harassment, Nathren then decided to build a substitute for all that, and converted a lawn mower engine to water which was successful and can still be seen on Youtube videos,- S1R9A9M9 videos 1+2.
The S1R9A9M9 engine conversion to water in carburetor may relay on Radiant Energy flowing down circuit to spark plug chamber. The earlier Patented ignition circuit that uses Radiant Energy release from modified CD ignition was from the 2nd. discharge of residual capacitor content into transformer primary that passes through capacitor diode that is connected to High Voltage output. The diode is open, then closed. When the accessory current passes .through, the Radiant energy from diode also goes out. Nathren's 2005-2012 conversion of V8 engine and the Briggs 18HP was different circuit, but may have had same influence to spark plug. The cars had dual coils relay, per cylinder with many diodes. The half wave DC charged the inductor with diode output. The CHARGE is released when plug fires but uses the coil energy INSTEAD of a capacitor type energy. The engines ran on water vapor pressure + fired Hydrogen gas from plug electrolysis. The coils inductance was necessary because of the desired on time in Milliseconds, not Microseconds as with cap discharges. His car tooled around for about 3000 miles on 18 miles per gallon water, until locked up in security garage. The 3 technicians there in Georgia said the Relays sealed in vacuum were worth their weight in gold. It seems they were just lucky to have it hooked up right. They did not know how they actually worked ! The AC traffic signal control pole relays were not used as normal click type method.The contacts and L + L coils passed HIGH VOLTAGE and also low voltage. The Briggs 18HP riding mower engine had to have an added triple magnetic coils assembly since there was no easy way to change timing from preset TDC to -34 degrees late timing. The cars' distributor turned easily to change timing. There was data saying from the now shut down web site, that parts added to plastic tub on side of Briggs, was referenced to the Tesla Hairpin circuit that formed Radiant Energy. The high volts ignition fired accessory spark gap with capacitors , so that other side of caps produce Radiant Energy transferred to primary of S1R triple coils primary. The passing through high volts to plug carried this radiant Energy along with approx 10amps current. Briggs started with 12v battery, then completely disconnected. The engine ran on just the dual alternators output, since there were 12 MAGNETS under flywheel for free power , as long as the crankshaft was turning. Nathren neglected to say it was self running. The Yellow + Yellow wires or Black + Black wires Briggs ring alternators can produce 14 amps and higher with bridge rectification. One diode would allow just about 10 amps half wave DC current. The original relays are discontinued and no longer available to purchase. Diagram of same is on Internet with (2) 1.5 Millihenry inductors with centered in series diode.. The technicians back then hand made 2 relays to simulate the originals, but failed. The built relay circuits were in open air, not vacuum. The vacuum holds in the white Radiant Energy generated on the enclosed diode output as 90 degrees perpendicular to wire concentrated, so as can follow further down the circuit. The Necessary Magnetic field over Briggs plug wire carries down to spark plug electrodes, as does with auto engine. They called it "Electromagnet". After about a year tinkering, they finally found out how to make engine run smoother , by the type engine used as having An EGR system mounted.The Nitrogen content of expelled moisture is reused as from compression of air into water which is 78% Nitrogen.
