I see no point in producing amonia on-board except for the fact that H takes up a lot of room in the combustion chamber which decreases power, relative to a petrol powered engine??
Atomic hydrogen has 3 times the power of H2. You cannot contain atomic hydrogen that is introduced
into the engine, you will lose it past the rings, etc... You need a bigger molecule that will carry hydrogen
into the engine and THEN have atomic hydrogen freed AFTER compression and when the plasma
ignition hits.
If you try to produce atomic hydrogen from the WFC, which you will not succeed - it simply combines
back to HOH or HHO. So creating a lot of water gas in hopes of providing a lot of hydrogen in HOH,
HHO or even atomic hydrogen isn't even the point of the WFC. (0.3 liters per minute is the cell setup
that Stan recommends "small scale" according to the referenced page). Most others with WORKING
knowledge of water fuel are making 3-6 liters per minute so more than Stan recommends but
A LOT LESS than is really needed to run an entire engine on HHO because running the engine on
HHO is not what Stan Meyer was doing. Every cell he ever showed running in any video never showed
enough HHO production to run an entire car engine on just HHO.
Small 600cc engines can work with just HHO to run it but then hook it to
a generator and make enough electricity from that to make its own HHO. It won't work because
you're only getting a fraction of the power from hydrogen by burning it HHO form.
HHO (small amounts) is only a catalyst that
when the plasma hits, there is dissociation of diatomic hydrogen into atomic hydrogen. This small
amount of hydrogen that is sourced from HHO or HOH is burned and nh3 in presence of atomic
hydrogen and atomic oxygen is extremely combustible. The ammonia is your main source of hydrogen.
Remember there is heat and pressure at this point.
The exhaust is a tiny amount of h2o and a lot of nitrogen. There can be traces of nitrogen oxide type
compounds that can be recycled.
Between those that have success, they each have their own specific viewpoints on the sequence
of steps in the reactions. However, there is no debate about the fact about ammonia.
