Hey guys,
I am in the middle of an HHO Gen build.
I have done some research part of it being the people in the video on page 1. It is Roy McAlister and I have read his book
Solar Hydrogen Civilization. In it he gives some concepts of how hydrogen is supposed to work in an ICE.
Because H2 has the fastest burn rate of any gas it is most efficient to fire ATDC in your engine. This allows much less heat to be absorbed in the cylinder walls and more energy to push the piston down. It was also said that you can use H2 along with other fuels and the mixture, as long as it is at least 5% H2, will burn "like" H2. The analogy being if you set a room full of cardboard on fire it will burn slower then if you used a little gasoline on top of the cardboard then it would burn faster, like gasoline. In the same way you can burn cheap, junky fuel with hydrogen and it will burn up "like" hydrogen.
All that said, I have learned some theory about how this is supposed to work so I am going to apply it in a scientific way to see if HHO will improve FE.
I bought a scanguage and have been trying to get some good baseline number unmodified.
I plan on tweaking with my O2 sensor, MAP, and whatever else if I have to in order to get my engine to run lean. From my research this is the only way to see improvement with HHO from an EFI vehicle.
I will be testing some engine load info on the alternator amp draw requirements when the system is turned on but not hooked up to the car. I will test when it is running and then I will test with everything back to stock. If this thing ends up not to be effective then I go to phase II, which is a tank of compressed hydrogen to add to the fuel.
I love to experiment after I learn so this is the logical thing to do. Theory is one thing but you can't beat experimental data. At some point you just have to try it to see if it works.
