What are the possible explanations for water doping in engines? by Christophe Martz. January 2008.
This article will attempt to answer this question as scientifically and seriously as possible. This article is the continuation of the article: summary of the facts and outcomes Gillier-Pantone process
Operating hypotheses concerning the Gillier-Pantone system and the role of water in the combustion chamber.
There 4 possibilities:
A) Water is physically and chemically transformed into the reactor.
The obtained product is directly involved in combustion.
The water is therefore chemically decomposed (at least in part) during its passage through the reactor with or without recombination with the compounds of the air: N2 or O2.
Reactant entering the reactor: H2O + air = H2O + + N2 O2.
Combustible products that can leave the reactor: atomic hydrogen H +, H4N2 (hydrazine), hydroxyl and hydronium ions: HO- and H3O +, hydrogen or nitrogen peroxide H2O2, H2N2, etc. etc.
Conditions of these changes? Two main theories:
a) Theory of ionization of the water vapor. The electrical charge of the water (ionization) during its evaporation and passage through the reactor will greatly improve the combustion of the fuel. We recall that combustion is an ionized gas. Find out more: read the water vapor ionization theory or measurements of the electrification of the air in a reactor.
b) gas Cavitation Aerodynamic shocks.
B) The water is not transformed in the reactor.
The reaction then proceeds to the motor: in the cylinder and the combustion chamber.
Several possibilities, the reality is probably a combination of all these effects:
a) mechanical aspects:
- improvement of the hot gas expansion: the pressure is more homogeneous on the piston and longer, the flexibility of the engine is improved and the knocks reduced, PV diagram has a larger surface. Improved efficiency.
- improvement of the sealing of the pistons, the oil becomes dirty less quickly and any oil consumption is reduced or even canceled (observation by almost all the experimenters)!
- better fuel dispersion and volatilization leading to better combustion.
d) thermodynamic aspects:
- Thermodynamic looping by pumping the calories lost at the exhaust and reinjected into the engine cycle.
However, this goes against Carnot's efficiency (the higher the temperature differences between T ° intake air and T ° combustion, the better the efficiency). However, injecting air that is already preheated (not to mention the loss of fill rate) into a diesel engine can result in a much higher final flame combustion T °: the “hot-cold” difference would therefore be greater in absolute terms.
The exhaust temperature would therefore logically also be increased, but this fact has been observed by many experimenters of doping with water.
- The possible presence of liquid water (mist), an incompressible compound, in the combustion chamber would increase the compression ratio. Improved performance.
c) Chemical aspects:
- Transformation of water by cracking during combustion by thermolysis. This is possible and beneficial if this reaction uses heat from the calories normally lost in the engine cycle.
- Water would be a catalyst or a reagent of another reaction?
For example: reaction with carbon from the fuel (C + H20 -> H2 + CO). Hydrogen is thus obtained, which will greatly promote combustion. CO is a fuel which will be transformed back into CO2.
Another advantage is used and therefore the presence of solid carbon is reduced which appears in the engine. In other words, it greatly reduces soot and particles.
But one fact was noted by all the experimenters: the engine smoke less. This reaction is very credible hypothesis.
Results: less black smoke, cleaner combustion chambers and oil for longer. Possible improvement in oil and engine life.
C) Doping with water would only restrict the engine.
This hypothesis, defended by the skeptics and confirmed by the few or no results on the test bench, is obviously defensible.
But, in fact, it could prove to be beneficial at the consumption level since we would thus achieve a kind of downsizing virtual and retroactive, that is to say with the great advantage of not having to change the engine.
However, some experimental findings go largely in the opposite direction (better flexibility always observed by users) ...
