Re-engineer an ICE Project Page 1

For a better understanding of what these photos are about,
please read the topic- Re-engineering an ICE to run on hydrogen.
This is the cam in a briggs 3.5 hp.
As it is plastic, I initially gave up the idea of modifying it.
Changed my mind.The exhaust lobs were cut
to decrease the opening and closing time.
The intake valve was cut a lot on the back-closing side.
The idea was to close the valve at 90 degrees.
I think it closes at about 95-100 degrees.
Then I used JB Quick weld to form cam lobs 180 degrees to
the other side of the cam. I drilled some small holes
for the JB to attach to. These were then cut to match the other side.
All work was done by hand, using a dremil for the most part.

As you can see, the small gear on the crank has
to make two turns for the cam gear to make one turn.
It would have been a little simpler if we could have
just changed the cam gear and crank gear to matching sizes.
On a vehicle, that may be what we do.
But the cam will spin twice as fast, so it may not
work in all vehicles, as the cam bearings may suffer
excessive premature wear.

Here is the timing change. The slot in the flywheel
on the left is the original. The slot on the right
with the dowel pin was hand cut.
First a small file was used, then a hack saw blade
was used to square the edges. Primitive, but effective,
as you can see. The timing was retarded 115-120 degrees.

I show this as a comparison. The intake port
is a little over 3/4" in diameter.
I will try a 1/4" barbed fitting (3/16" inside)
to supply hydroxy, or plasma gas (aka Waterboy's method).

Here is the finished intake manifold/carb assembly- HA-HA!
This will be connected through bubblers, plasma cells, etc.
to the Water Fuel Cell- hydrogen booster.
I have done a pre-liminary start proceedure.
To my surprise, it actually pulled a vacuum on the booster,
as the bubbles in the bubbler clearly showed.
No starting yet, as hydroxy production must have been
to low (1/8 LPM- no plasma cell). Remember, no compression stroke,
so pulling the rope is easy. It was fun spinning the motor with
the head off and watching the valves open and close on each revolution.
