Did it back in the early 90's at one of the big three. We used a metal hydride ( magnezium oxide )tank to store the Hydrogen. The engine was started on gasoline and the exhaust was used to heat the hydride tank. When heated it would release Hydrogen that is absorbed by the magnezium oxide. It would tend to backfire on hard accel because the hydrogen in the intake would ignite when the intake valve opened. Could probably fix that by installing injectors close to the valves. That would prevent a large amount of hydrogen from accumulating in the manifold. Hydrogen loves a high compression. It seemed like 14: 1 would be ideal.We didn't go to far with the project because it was not one of their " important" programs. I am putting together a turbine that runs on hydrogen. Dan
We used gasoline to start the engine and the exhaust heat caused stored hydrogen the come out of the magnezium oxide. When that occured, the engine was switched over to run on hydrogen only. Dan
You can run an internal combustion process on nearly any flammable fluid. Ever priced them? It's not a coincidence that even @ 5.00 a gallon, Gasoline looks cheap...
GM converted a Hummer H2 to run on Hydrogen for Gov. Arnold in California back in 2006 or early 2007. The GM guys told me that they immediately lost 50% of the engine power because the Hydrogen fuel doesn't have the energy density of gasoline. Lots of Alt fuel people say that "Hydrogen is the fuel of the future.......and it always will be!"
Unsurprisingly enough, there are a few very solid reasons that we ended up using Gasoline for internal combustion. It is easy to handle, and it's energy density is VERY high. It's also cheap.
this subject has been covered as such in this thread http://www.jalopyjournal.com/forum/showthread.php?t=263083&highlight=hydrogen maybe some information from that one will shed some light on the matter. there are some videos of a 4 banger running on hydrogen and the gentleman explains how it all works.
