Hydrogen fuel cell car! HAHA!

Giroux sells a system of modifications that disables the engine management's computer and makes the engine run extremely lean--as lean as 20:1. That's far from the normal 14.7:1.

That right there is enough to cause detonation and ruin any engine fast. Neat concept and good info, and reading in this thread but im thinking that we wont see this in any near cars in the near future just like E85 isnt avaliable to be used in all cause because of the size of the injector (i.e. the amount of fuel it takes to create the same combustion as gas) and tune it takes to run.

 

IMHO my hydrogen system is in fact improving my fuel efficiency. I have seen it first hand in the results. I know there are several popular mechanics articles out there to discredit this but until you try it for yourself you shouldnt believe everything you read. In my book the results stand firm and the system (while not consistant) works.

 

How do you know in fact that its working or delievering more fuel milage? I see that you drive a saturn what kind of tuning do you use? I actually have methanol on my car now to make more HP and it reduces the combustion chamber temps by 200-300 degrees but it has to be dialed in carefully and I closely monitor it with a A/F ratio gauge.

From what was posted above and what It seems like it its not really benifiting you I just would like to seem soild proof as in numbers showing its working.

 

When what you see conflicts with hudreds of years of careful research by the greatest minds to have lived, a little bit of humility and healthy skepticism is in order. Skepticism is a good thing; it leads me to recognize that there is a remote chance that, in spite of the provenance of the laws of thermodynamics, they are falsifible.

Until you can articulate a reasobale hypothesis for why "it works" and support that hypothesis with a controlled experiment, I'm going to give this, on balance, to established physical laws. To do otherwise would be to believe the sun revolves around the earth simply because I see it happen.

 

Do me a favor and try two things. Run the hydrogen with the original tune and check fuel economy. Put the tune to what it is when you run the hydrogen only without running the hydrogen and check fuel economy.

Not true, at WOT vacuum drops to atmosphere.

 

Exactly, this is what I ment by injecting it, but first you need to know many various things. This could be done using a nitrous set up- just no NOX tank. Or use an empty NOX tank for hydrogen storage.

The actual engine's fuel demad for a given power curve.

Average RPM at which this happens.

Altitude (atmospheric presure).

ECM type and if it is programable.

What type of OBD system is used? This will tell me what sensor's and such are involved.

 

Excatly- controlled, as I previously mentioned- w/o documentation of what is done, was done - what works and what doesnt- it's not something J.Q public would be able to reproduce.

 

I can't imagine it is producing that much hydrogen. When they tried testing this on mythbusters they couldn't get a significant amount of hydrogen produced without a significantly larger setup then what you have there I believe.

Not true Leighton, here is why- since we can't swap out injectors, what we can do is regulate and vary fuel pressure- there by causing several things, first, a different spray pattern, second, higher or lower fuel pressure, third, volume vs presure differences due to atmospheric presure.

By way of example- today I had a car come in with a #4 cyc. misfire, but it would only misfire when turning LEFT. So I pulled the plug- strange looking stuff, so I did a quick comression test- no problem there, so I pulled the injectors, the fuel smelled funny and had a weird feel to it. So, then I pulled the fuel line and took a sample- hmm, seems ok, so then I pulled the fuel pump, looked into the tank and WOW. Guess which side the pump was mounted in the tank?

Tank was 1/2 full of water- seriously- WATER, the car ran great other then low power and the #4 misfire (ck engine lamp).

Moral of the story: Todays ECU based vehilces that are flex fuel will run on nearly anything, and this story is proof of that. BTW, the fuel she put into her tank- it came from a BP station~ ironic.
