I'm thinking the only way to do this, as I made perfectly clear earlier, is to pay rediculous close attention to detail as it must be done just right for this to work at all. miniturization is one thing, but what is more difficult is keeping it simple while maintaining ease of use and functionality.
Now, no one else in the whole world has paid as much attention to the harnessing of combustion byproducts than the automotive industry. That being said, many ideas can be taken right from there.
I imagine a piston chamber design where, instead of driving a crank shaft, the piston shaft would merely guide the piston. A spring and rubber block in the chamber and behind the piston could provide a "softer landing " to the back of the piston head. An adequately sized ventilation hole positioned in the chamber wall just below the piston face when it is in top position could vent the gases into a diaphragmed storage tank. This type of storage tank allows you to fill compressed air into a special nozzle which pressurizes the tank's contents, while the diaphragm inside separates the compressed air from the usefull contents. From there on out it's just a matter of "scrubbing" the gass.
There is a lot there, and valid.
However, an analogy of the "combustion unit" to efficiently produce Co2 to the internal combustion engine is in error.
Much more efficient designs in carburetor design (example, a vapor carburetor instead of liquid introduced to the air stream through jets--i.e., fuel wets a fiber pad with air pulled through to evaporate the gas into the fuel/air mixture/vapor, replace the liquid/jets) and fuel injection could be employed in the combustion engine. Patents are held on these designs, they are just not practical to implement--from what I have read, it is the heat ...
Indeed, pollutants could be cut, just through such methods, where pollutant levels would drop in magnitude (and mileage increased by magnitudes.) However, the "heat of combustion quickly becomes a limiting factor. Holes are melted through piston heads, the cooling system would need to be of ridiculous proportions, oil would boil, etc. You just could not deal with the heat, it would build faster in the engine than it can be removed.
In the design we are discussing, for a Co2 generator, the heat from so small of combustion might be easily handled--literally a candle flame! (low BTU's) The combustion chamber could be red hot, resulting in VERY efficient burning of the fuel--indeed, it could be of a ceramic material (such as the ceramic insulator removed from a sodium vapor lamp, and pressed into service here) and temps can now go to white hot! I would think 99.9999999999999999999999999999% combustion efficiency would begin to occur. And, we would not be using gasoline, perhaps ethyl alcohol--something we can drink. Of course there would be a danger if efficiency levels drop low--the fish would get drunk! <LOL!>
But, yes, like I say, I have been thinking about this, will get time this winter to play with it in the garage ... again, good input! I am sure I will run though this discussion in my head, more than once, as I am "playing around."
