Required hydroxy to run 2.5L 4 cyl

[Cobra]

HAHA ok before this goes anywhere further (and Bob is correct and on a much higher level by the way) why are you guys thinking about running an engine built for hydrocarbon fuels and expect reasonable SFC numbers? Experimenting is fine but don’t expect miracles on a poor engine design. Now then if you want to start off on the right direction let’s talk about engine modifications first hand to cut the fuel requirements in half.

Actually, that production came from a unit that was no bigger than the average car battery. The car battery can be relocated to the trunk to clear space underhood if need be. And yes, you would be suprised how little hydroxy gas it takes to actually run an engine. Until you stop calculating and start doing, you'll never find out for yourself.

I was not trying to be ugly at all. I am trying to impress upon everyone that calculations are not the answer. Depending upon how you generate your hydroxy gas, determines the power that hydroxy gas will yield when burned. So there is no hard and fast "one formula covers all" that will work in this case. The composition and behavior of hydroxy gas can vary based on the method used to generate it, and how quickly after generation it is burned.

The welding gas generator in the project pages was constructed with 71 series 6" X 6" plates. So yes, it is large, but not any larger than a large car battery. The plate spacing is 1/8", so it does not take a lot of room for 70 cells of that size. The DC production rate of 15-16 LPM is just that, production at DC. With the resonance drive, that unit can produce 75 LPM without a problem. Just look up posts and info on the PWM3E, or the HexController (not yet released) which is the next generation unit that gives more precise production control.

The welding gas generator sized units run from 120 VAC rectified/filtered to be about 156 VDC. It can also be powered from an inverter that takes automotive 13.8 VDC and steps it up to about 160 VDC. Normally that output is fed to an H-bridge to output simulated 60 Hz AC. By bypassing the H bridge, you have a source of about 160 VDC.

However, you will not see me post anything about installing such a unit in a car. That is not my goal, nor my driving force. The reason you do not see me talk about more is I do not go into details of everything I do, on a public forum. All I will share is my research as related to boosters and welding gas generators. I've experienced first hand what can happen when one dares to go against the status quo, and I do not care to experience it again. I leave that to others to experiment with and talk about.

I agree, the price of 316 is getting so outragious. 304 will work at reduced efficiency. You can buy or build a DC to DC converter (buck converter) to provide whatever operational voltage/current you desire from an automotive source. There are some that get some pretty darned good efficiencies to boot as well.

Hi Bob.
I have some question:

1.What kind of reonance you are using to improve efficiency from 15L/min to 75L/min(PWM3E or some other resonance).

2. can I use resonance for "Chris " design(maybe 60-70 cell)

3.does PWM3E works for one cell electrolyser?

Thanks
