How to build a hydrogen car (The engine) 

Glad it was helpful!

That’s ace! Thankyou for the support. PEM stacks can be used to create pure hydrogen at one output and pure oxygen at the other right?

That would be perfect! When running hydrogen with port injection forced induction is needed to get back some of the lost power. Thanks for the info

Direct injection would be a lot better, but port injection still works. Glad you found it helpful

You can also use urea and ammonia to produce Hydrogen 👍

It’s an ace idea, this car runs on pure hydrogen though, so the electrolysis machine would have to output pure hydrogen and pressurise it to 150bar or so, that’s where it gets tricky. No impossible by any means

Maybe, I use an oil catch can which helps a lot

Keeps it dense, storing hydrogen gas is extremely difficult. It defuses through and/or embrittles just about anything it touches, after awhile. Not to mention, as mentioned in the video, its a very sparse gas, not dense. If you just pumped to atmospheric, there wouldn't be very much there. Liquid would be much better but the system for that would be far more complex and expensive.

Hey! @Hydrogenguys thanks for the heart, coming from you/someone alike, that actually genuinely means something.

Anytime, it was the perfect reply to a good question, Thankyou for the comments

Hydrogen can produce a lot more heat than petrol, and more friction as hydrogen is a non lubricant, as this engine was designed for petrol, it’s safe to say the piston rings and sleeves won’t last as long as they would on petrol. These are issues that are solvable if the engine was designed for hydrogen in the first place. Hope this answers your question.

@@Hydrogenguys it did, thank you!

I would like to know more

This fuel tank doesn’t last long at all, too small really, I will upload a video about this next Monday hopefully, think I may have mentioned it in the previous hydrogen car video

@@Hydrogenguys Maybe if you change the AFR by putting more air and less hydrogen at low speed and high speed you leave the same volume of hydrogen you have but more air might be better because you will consume less and more power

@@Hydrogenguys Or if you can change the AFR by putting more air and less hydrogen when you press the accelerator from 0% to 50% and from 50% to 100% you leave the same volume of hydrogen that you have but a little more air and the ideal would be to leave the same volume of air and less hydrogen from 0% to 25% of the accelerator and from 25% to 50% you put a little less hydrogen than you normally have and more air than you normally have and from 50% to 70% you put a little more hydrogen and more air and from 70% to 100% you put more hydrogen and more air I think you have a bigger power and you will consume less

Cooling and complexity, as hydrogen is a gas’s it occupies much more of the cylinder then a liquid fuel, meaning less oxygen than normal resulting in a rich mixture, the car needs to be direct fuel injected or forced inducted via supercharger or turbocharger to overcome this. The rich fuel mixture also reduces engine heat, hope this helps :)

Hi, yes this was 100% pure hydrogen gas.

@@Hydrogenguys That's great, did you run without petrol? And how many mpg do you get??
