This GenSet ICE conversion to hydrogen seems
fairly standard. I would be glad to answer any
questions anybody has about about the GenSet
and its conversion. Unfortunately I don't speak
German so I can't be criticized too harshly for
what I say.

One reason for the device's instability is that he doesn't
seem to use a hydrogen or hho gas metering valve.
He removed the throttle body when he got rid of the
carburetor. That medium plastic tube breathes air
into the carburetor port...The hydrogen air mix is non
stochastic mixture because of the nitrogen in the air.
You don't really want to form a partial vacuum using
only the stochastic mix of HHO into the engine because
the compressed volume won't be the same as with the
70% neutral nitrogen gas in air.
So he is pretty much using a wide open path for produced
hydrogen to enter the engine. One way to control the
amount of hydrogen produced would be to control how
much power is directed to the electrolyser.
He has disconnected the mechanical governor that controlls
ICE engine throttle RPM when using hydrocarbon fuel. This
is designed so that generator unit run at about 50/60Hertz.
The other thing is he stopped using the engines internal
flywheel magneto spark coil and he has built a simple
electronic ignition trigger using a hall effect switch and
a glued on magnet so he can fire that auto ignition coil
near 0 degrees TDC Top Dead Center required for hydrogen
combustion. That wooden stick controls fine tuning of the
firing angle. The generator shaft is directly linked to the
engine crank shaft and those plastic gears as are the 2
to one ratio required to fire the spark once in the four
engine cycles.
I kind of like the concept more of direct connection to a high
power 12V Alternator so that one can use a car battery to
stabilize the power loop path. The probability that the electrolyser
cells are producing exactly three times the required power is nill.
So you are going to have to control their output. One way to
do that is control the DC power supply to the electrolyser. With
a variac and a light dimmer control substituted for a throttle.
The electrolyser power supply is probably that boxy unit with
the dual red and green digital meters, that he is adjusting.
So the magic, if there is any here, is in the Anton electrolyser
cells themselves about which I know little.
