All,

In my last post I showed the ignition/injection pulses and explained HOW they are created.

So, what’s next?
How does all that relate to an engine?
More importantly, how is it APPLIED to an engine??

THAT is the subject of this post!

Remember one of my earlier attachments, a file named “engine timing 2.pdf”?
(4 stroke engine timing cycle)
If not, I suggest you go back to my post (reply # 166) it was attached to, save it and PRINT it!
Now put that drawing on your desk and turn it about 30 degrees anti-clockwise.
(So that the line with the markings of 270 – 0 – 90 – 180 – 270 degrees which was horizontal before, now is on an angle, RISING to the right!

That rising line you now see is the SAME as the ‘slope’ of the saw tooth in those oscilloscope images in my last post!

Just for the readers of this Forum (yes, both of you! ) I have made an additional drawing which, together with the previous one, may lead to better understanding of this subject!


For those who are prepared to “get their hands dirty”, I can offer some general suggestions on how to set up this ignition/injection system on your engine.

Make sure you understand and follow these instructions closely!
If you don’t, you will not only end up with a non-working system but also run a real risk of doing DAMAGE to your engine!

(I like to draw your attention to a post made by ‘bolt’ earlier in this thread: 
“if you don't change the timing the engine runs like a pig, back fires, can bend valves and can burn hole in piston. Plus it requires a HUGE amount of gas just to barely run. When properly tuned and blank spark sorted all these issues vanish.”)

By the way, a properly set up fuel injection virtually ELIMINATES back fires!

That does NOT mean that you should operate your set-up without a flash back arrestor!

IMO, you should NEVER, EVER operate ANY kind of system running on HHO without an appropriate flash back arrestor!
It is the “life insurance” of your electrolyzer and perhaps your entire system!

OK.
First, REMOVE the fuel tank, the carburetor (only if you want to use injection) and the ignition module (which most likely includes the coil) PERMANENTLY and the valve cover AND the spark plug TEMPORARILY!

*  There are two reasons for removing the spark plug:
1.  It will be MUCH easier to turn the crank shaft by hand as there is
     NO compression when the cylinder is OPEN!
2.  It is easier to determine when the piston is at TDC and BDC.
     For BDC you may have to use a ‘stick’, (through the plug hole) placing one end
     of it against the top of the piston.
*  After you have removed the valve cover, identify the EXHAUST valve and its rocker
    arm. 
    Since this arm is most likely made of steel, the magnet will stick to it.     
    Once you have determined the TYPE, SIZE and the POSITION of your magnet and it 
    operates the Hall switch properly, it can be glued to the arm, using HIGH temperature
    Epoxy resin.

Note: we may (or may not) get away with using ‘Neo’ magnets.
It will depend on how hot (or cool) the engine will run with ONLY HHO.
‘Neo’ (Neodymium-Iron-Boron) magnets start losing their magnetism above 150°C!
We may need to use Samarium-Cobalt or even ‘Ceramic’ magnets (which can “take the heath” but are not as strong as ‘Neo’s).

*  Make a mounting bracket for the tiny Hall switch circuit board and attach the
    assembly TEMPORARILY to the engine block in such a way that you can easily
    ADJUST its position.
*  Apply 12V DC (with the correct polarity!) to the Hall switch circuit.
    In the absence of a magnetic field, the LED will turn ON at power-up.
    (This may only apply to the Melexis Hall switch I use.)
*  Now turn the crank shaft by hand and watch the movement of the rocker
    arm with the magnet AND watch the indicator LED!
*  The physical POSITION of the piston where the LED turns OFF, corresponds with the
    vertical “retrace” line at the START of the slope you see in the saw tooth waveform!

The purpose of the process I just described is to find (in degrees of camshaft rotation) the physical position of the piston when the pulse from the Hall switch arrives!

From there on, from this single pulse, our electronics is first going to derive not just one but TWO different pulses (ignition and injection) and then place them EXACTLY where they need to be!

(The details on how this is done is explained in the circuit description.)

A few words about the new drawing:
The large RED dots on the slope indicate the TDC and BDC positions of the piston.
The 4 BLUE dots are half-way position marks (45°) in each of the 4 cycles.
The BLACK dots mark each 10° of CAM shaft rotation.
Dotted lines (GREEN and PURPLE) indicate the limits of the injection and ignition pulse positions.
BLACK dotted lines show that the Hall switch pulse length is almost the same as the opening time of the exhaust valve.

The RED and BLUE horizontal lines intersecting the 30° slope of the saw tooth are the voltages applied to the ignition and injection comparators, respectively.
Both pulse POSITIONS on the slope are adjusted by varying these voltages!

THE POINTS WHERE THESE LINES INTERSECT THE SLOPE INDICATE THE PISTON’S POSITION IN THEIR RESPECTIVE CYCLES!   

More to come…..

Re-filling electrolyzers

Why do I bring up this subject?
Some people may not consider re-filling – manual or automatic - to be a ‘problem’.

It depends on your definition of ‘problem’.

Over the years, I have seen very few researchers/experimenters attempting re-fill of their electrolyzers, particularly series cells, without first shutting down their entire system!

I guess that was/is due to the technical difficulties it presents.

OK. 
Here is the scenario:
You finally got a “self running” (looped) generator running on water (HHO)!
While the volume of water it consumes does not seem great at first glance, there is a BIG difference between a demonstration lasting just a few minutes (or even an hour) and a  CONTINUOUS, 24/7 operation!

Here are some practical figures to consider:

While “calculations” seem to vary by a large margin (depending on who’s “figures” you are looking at), the fact is that if your electrolyzer is reasonably “right”, you will get at least 2000 litres of HHO from 1 litre of water.

Suppose your (LARGE) generator needs 10 litres of HHO per minute.
That is 600 litres/hour.
So, 1 litre of water will run that engine for 3.33 hours.

EVERY 24 hours it will consume 7.2 litres of water (14400 litres of HHO).
 (A smaller generator will use a lot less.)

Since the HHO used in an engine re-combines into water, you can collect it from the exhaust pipe and re-use it.

But before you pour it back into your “fuel tank”, I suggest you expose it to sunlight for a few hours to RE-ENERGIZE it!
No, its NOT a ‘fairy tale’ story, so don’t knock it!
The effect is real.

In order to get the HHO to enter your engine, it needs to be under pressure.
Actual pressure depends on which method you employ to feed the gas from the  electrolyzer to the engine.
It should be obvious that since the electrolyzer is under pressure, you cannot just open a valve and pour water into it!
Thus, MANUAL filling is out of the question while the system is operating!

Who would be willing (or should I say crazy enough!?) to STOP the engine EVERY TIME more water is needed, purge the electrolyzer (let out the gas), fill water and restart everything???

AUTOMATIC filling is possible if using a one way valve (check valve) in the water feed line with a pump which can deliver HIGHER pressure than that of the gas in the cell, PLUS overcome the “cracking pressure” of the check valve.
(Some pumps may have built-in check valves.) 

My series cell electrolyzer re-fill is a two stage process.
How it is done is described in my “Re-filling series cell systems” article.

Once a thread is OFF the main page, it is very difficult to find!
I can only imagine what new (visiting) readers think of all this.

..."EMPHASIS cannot be properly expressed"

Well,
you CAN look at the last 500 posts,
if you desire to drill down further actually.
(My "Emphasis" intended as sarcastic humor towards OP...)

One question if I may, your intriguing tit-bit above regarding the 2000L of HHO per litre of water  - far far less water used than I would have thought - got me thinking again about cells under vacuum.  As you are pressurising the HHO anyway, would it be at all feasible to evacuate the gas from the cell with a vacuum pump, feeing the gas sucked out into your gas storage, while also increasing the rate of gas production due to the partial vacuum?

‘Sprocket’ & ALL,

The “2000L of HHO per litre of water” figure is rather conservative.
It applies to electrolysis using DC current and the evolved gases are di-atomic. (H2 + O2)
If, and I say IF, a system can create ALL the gas in mono-atomic form, that figure would DOUBLE! 
(And YES, it is possible, using RESONANCE.)

So, depending on the set-up, the real figure will be somewhere in between those figures!

About vacuum:
Personally, I have NOT tried this method but I know some experimenters have attempted it with dubious results. 
But, over the years it all faded into obscurity, just like most other things in this  “free energy” chase!

For the set-up you are suggesting, you need to consider the practical side:
1.  Quality vacuum pumps are NOT cheap!
2.  Energy required by the pump.
3.  Extra (pressure) container is needed!
4.  How much (if any) increase in gas production can be gained?
5.  Is it worth the extra expense and complexity?

Perhaps I should have pointed out the OBVIOUS advantages of my set-up earlier but since you raised the vacuum issue, here they are:

1.  The electrolyzer CREATES its own pressure, automatically.  NO extra energy needed. 
2.  The electrolyzer also serves as PRESSURE VESSEL and gas STORAGE TANK!

Hey guys I have an affordable plasma ignition system listed on ebay. Just search gorilla plasma ignition on ebay. I am looking for hho motor builders to test my system. It is way more affordable than commercial overpriced systems from aquapulser ignition etc. I build them myself.  Here is a video...
http://www.youtube.com/awatch?v=peO1afaBX5E

Thanks guys.

No offense but your post indicates (at least to me) that you are NOT familiar with the characteristics of HHO gas.
One of the characteristics is that it requires only a VERY, VERY low energy spark to ignite/detonate!
Thus, HIGH energy sparks, particularly PLASMA sparks, are a HUGE over-kill and thus are completely un-necessary!

In other words, this is the wrong thread to promote your plasma  ignition system.
