Hi everyone,
I just signed up to this sight a few days ago and been reading through as much as I can. There are a lot of great ideas here and a lot of good hard work has been accomplished here.
My thoughts are on engine modifications to run hydrogen is that you don’t have to worry about rust! I don’t believe that water in the engine will make any difference to the normal engine operations. My reasons are this. When an engine runs it burns hydrocarbons and when you bun hydrocarbons you make CO2, CO, H2O from the Hydrocarbons plus the nitrogen in the air will make NO2 at high temp and pressure burning. Sulfur in the gas will make SO2 and when it mixes with the H2O steam it will form into H2SO4. The first point I am trying to make is that the Hydrogen in the Hydrocarbon will always make H2O in the burn and there is a lot of Hydrogen in a Hydrocarbon. That is what makes it such a good energy source. So if we are burning Hydrocarbons in the engine we are basically burning Hydrogen plus carbon. The carbon is what makes all the soot, and green house gasses. There is a little energy from the Carbon getting combined into CO2 but this is minimal. If we were only burning Carbon then I would see your point. You can actually burn CO in an engine as it will combine with the O2 and make CO2 but this is very little energy compared to the Hydrogen been combined with the O2. I live in Canada and every winter you can see the exhaust plume coming out of the car…guess what pours out the exhaust until the engine worms up? Liquid water! This is from the steam been condensed in the cold exhaust pipe. Now this would be a huge problem if the exhaust and engine never got above 100C…but every engine does, and once you do get above 100C the steam will stay steam. If you every drive a car on really short trips only then you are doing huge damage to the car if you never get the engine oil above 100C. The oil will start to get water in it, and will stay there doing damage to your engine until you take the car for a drive and get that oil above 100C to boil it out the block.
My second point is that steam engines were made from low grade steal. They did not have exzautic metals for valves and other components. Internal rust was not a problem because of the steam as long as they run the engine until it was hot and above 100C. They had problems in the boiler from the soot and other corrosive gasses eating the metal but mainly the H2SO4. But again as long as they made sure the engine was ran until it was hot water was not the biggest problem.
Now high flame temperatures is a reason that I would except the need for exzautic valves, coatings, and different pistons, but until I see valves burning, pistons pitting or other heat related problems I don’t think that the water steam is going to be a problem.
I have not run my car on hydrogen yet, so all of what I have said is just theory. And I don’t have a problem been shown that I am wrong…but I do think that steam in the exhaust is really not a problem as we have steam in our exhaust now.
My biggest problem is now is still to make enough hydrogen from my WFC to run my car.
