How to make a Gillier Pantone reactor water injection in diesel engines?
This page is part of the dossierhelps the achievement of a water doping Gillier Pantone.
The description refers to the plan:

1) The reactor is placed as close as possible to the exhaust manifold. To get the most possible heat, it is best on the turbo diesel to place a small spoiler to channel the exhaust gases around the front of the reactor (steam output).
This deflector is linear, it's just a ring that channels the exhaust gas around the beginning of the reactor over a distance of 1 / 4 to 1 / 3 the length of the reactor, such as a flare tube and flared early exit (long venturi) with a narrow passage that all the exhaust gases are strangled on that part, not too long to create the least possible restriction.
Caution : no spiral baffle, it slows down too much the passage of exhaust gases and provides no advantage at this level: the drop in temperature is so sudden localized when the reactor operates, there is no interest in let stagnate the exhaust gas around the reactor.
2) The reactor tube is made of stainless steel. It is welded into the exhaust pipe, the ends may be threaded or tapped.
The usual diameter of the inner tube of the reactor is 1 / 2 inch, 15 16 mm was inside, but other dimensions may be suitable. Ensure that the clearance between the rod and tube either to 1 1,5 mm.
3) The rod is made of stainless steel and its diameter is normally 13 mm. But it can be adapted to the diameter of the inner tube of the reactor in order to have a game has 1 1,5 mm. The length of the shaft varies in 100 150 mm for doping water. More powerful the motor over the rod can be shorter.
4) to the outgoing end of the reactor, a screw cap 3 / 8 or 1 / 2 allows inspection and the possible change of the rod.
5) The diameter of the outer tube after the restriction, it aims to conserve the original section of the exhaust tube around the reactor.
6) The entrance of the stem is cut at right angles, and its output is rounded or slightly profiled. Welded or screwed a rod 4 mm at the end: it is a spacer that joins the cap (4).
7) The spacer is intended to position the rod: it always ends up taking the game with expansion and vibration, and it behaves like a piston in the tube, drawn forward by suction. Without the spacer, the rod would eventually clog the exit hole of the reactor gas ...
8) Center of upper: 3 solder pads is achieved "in depth" to 120 2 degrees to the ends of the rod. Then lime (or better in round) adjusting the soldering points so that the rod between just clamped and better centered in the tube as possible. [I] Please do not do bad 'balls' of welding, which can break off and join the engine! [/ I]
9) Regarding electrical insulation, insulated rods 2 have been tried: - One with solder nozzle ceramic nozzles TIG .This was complicated to do and did not resist long has vibration. - The other is a steel rod that is wrapped Teflon tape plumbing, then push force into a stainless steel tube. Then I soldered the centering pins on the steel rod, thus isolating the steel tube (measured Fluke) was very good. Testing I did not notice a big difference in the way the oil or to the old 30% frying oil, as I normally use.
10) Antichambre: positioning the rod so as to have an antechamber to 80 100 mm, it uses steam provided before reaching the stem. This hall can be shorter with a bubbler, it must be longer for a carburetor or a water injector, because water is sprayed less well with a bubbler.
The hall is very big on my breadboard, it allows me to walk with oil without heating the liquid or air intake. It absorbs almost all the exhaust temperature, which becomes cold: you can keep your bare hands while the engine running. It is through this enormous hall that I managed to operate with a high ratio of oil and engine oil.
11) The expansion chamber should be in the hottest part of the exhaust, if possible in an elbow. Normally a length equal to the diameter of the exhaust duct is sufficient.
The expansion chamber is important. Its purpose is to increase the temperature of the mixture in the reactor. This is the point that the most heated in the reactor, even more than the large diameter of the rod. I have some questions about it ... - How can the small spacer rod heat more than fat which is a 1 mm from the wall? - How is it that the thermocouple welded to the exhaust pipe there, hotter after the big rod? Indeed; if you move the rod, hot spot, measured exhaust side, seems to follow the tip of the rod!
This suggests that produces heat when the gas leaves the rod and arrive in a less restricted room. This happens over a short distance. By running the engine without isolation of the reactor, this hot part is visible: no need for thermocouple.
The usefulness of this room is not currently well understood, but these facts are easily reproducible ...
