How hydrogen engines work - RMIT University

[rmitmedia]

Hi @XxENovaxX, is this the link to the video you wanted to post? .../watch?v=5kdaUyJQ1IQ

[Fourteen88SoCal]

But will it blend?!

[joDRagneeL]

how do u get hydrogen instantly anyway?....

[SUPERCR0WL]

@joDRagneeL There's no such thing as getting hydrogen "instantly". It's either a tedious process of removing it from water, or separating it from air.

[brandon9966]

@SUPERCR0WL actually... with high voltage it is possible !!

[neiallswheel]

@brandon9966 also try High Temperature Electrolysis (exhaust heat.) have a look for Vortex Heat Exchanger (a.k.a  GEET ) alternative emissions reducing and fuel saving.

[neiallswheel]

@SUPERCR0WL look up Water Electrolysis and especially High Temperature Electrolysis ........these are the two main ways to get HYDROGEN on demand (from water H2O) using either electricity or exhaust heat. Also have a look for Vortex Heat Exchanger (a.k.a GEET ) another crazy, simple and efficient series of natural reactions that provide drastic emissions reducing and fuel saving results.

[cam1996reeves]

wow, thats a pretty cool achievement, but does the hydrogen corode the inside of the cylinder or piston in any way?.

[outseeker]

Some excellent information, thanks! :)

[Me102288]

Hydrogen burns 9x faster the gasoline. you do not need to compress it, nor do you need a special engine to run it..

ANY gasoline, propane, natrural gas, methonal, and diesel engine will run on hydrogen. The fact is simple, internal "combustion" engines runs on Combustable fuels.. but of course every engine needs to be tuned to use different fuels... it burns faster = retard the ignition, all I had to do with my carbourated engine...

[MrRobotoToo]

Hydrogen ICEs are so much more practical and cost efficient than fuel cells that it's hard for me to understand why fuel cells get all the attention. If the hydrogen economy ever becomes a reality, it's almost certain that most vehicles will be powered by hydrogen ICEs and not fuel cells.

[Itsmeeman1]

3 or 4 litres of petrol equivalent? That tank looks like it could hold more than a dozen gallons of petrol! Seems like a waste of space!

[keirus69]

@Itsmeeman1 if you listen, hydrogen is a sparce gas, needs to be compressed...

[vernie4163]

@Itsmeeman1 u r just envy and feeling genius. make ur own lad.



[Me102288]

I agree, hydrogen on demand is way better, if that tank ever got pierced and ignited, you've have a nice 30 crater. Truth is ALL combustion engines run on hydrogen with no modification needed.

[neiallswheel]

@Me102288 there are carbon fibre tanks on the market that are reasonable and bullet proof. i have seen a vid and cant find it at the mo,

[agubiz]

the tank is inesesary!! just with a converter cell is nought,u can get ur 5 bar presion in it and its 20x 20 centimeters to much stuff and complicated to charge it!! no mora gas stations!!!

[taztaz79]

@agubiz Convertercell? Convert from what? Are you one of thoose hillbilly's that think you can run a electrolyzer in a car and get out more energy from it than you put in? :) .. If you are not.. sorry.. :)

[Me102288]

@taztaz79 converter? did you not know ELECTROLYSIS has been known for over 300 years?

converts nothing... 1.47 VOLTS is enough to SPLIT water, whats water composed of? 2 parts HYDROGEN and 1 part Oxygen..

hydrogen is 9x more explosive then gasoline. Its a atomic chemical.. Maybe you'll understand octane better, pumpgas is around 89 octane right.. hydrogen is 130.. think about it :-)

[dying2l]

@Me102288 not an argument and I know its been around for a while. If hydrogen is that much more powerful how come people seem to be having a hard time converting gas engines to hydrogen.

[joDRagneeL]

@Me102288 agree...i was thinking of deriving hydrogen gas from electrolysis..but how can we and where are going to place the electrolysis device in a car engine?...= ="....and if so....what material tht doesn't corrode when we store inside?...OOMG....too much requirements...can som1 answer my questions...

[RestauranteChines]

Is the hydrongen engine similar to the otto engine? Or does it have a completelly different design?

[Xantec]

@RestauranteChines

its a 4 stroke otto engine i think, just instead of gasoline going into the carb, its Hydrogen. :) 

[Me102288]

@RestauranteChines its a simple gasoline burning internal combustion engine, they run on all kinds of combustable stuff... I've seen a gasoline sucker run on everything from propane, natural gas, to alcohol base fuels like methonal with %'s of nitromethonal in it.

Simple fact is hydrogen is 130 octane lol, nothing comes close to it. pumpgas is 89.. kerosene (jetfuel) isn't even 110.. Hydrogens some pretty explosive stuff. we can get away with using a lot less :-)

[magna59]

Very impressive piece of work.............its a little problomatic that you need such a large tank for such a small amount of fuel. Great it is about real engines, rather than a special experimental unit. Do you require any additional upper cylinder lubrication, as LPG ?

Best regards Bob

[buttdud1122]

how about lubrication? how do you keep the heat down and the piston/sleeve maintained with a long life? and is it glow or spark?

[Me102288]

@buttdud1122 hydrogen running in diesel engine requires you change from glow to spark plugs ya, If this is a sleeve valve engine the heat is the fault of the design of the engine, it has 2x the friction of a standard poppet valve system :-(

[brucekirk89]

better be carfull if it works the gorvment will take it from you and destroy it

[1100tech]

I thinkl you missd it mate! need to run straight water mate! through a plasma field to split it in the cylinder mate!

[matt4music]

No, he did NOT explain how a hydrogen engine works... he gave us a tour of the mechanics of how hydrogen is delivered to the engine.

[jtwestie]

@matt4music ...good point - however, the reason for it is a hydrogen engine differs almost none at all internally other than variable factors such as valve timing for example, than a petrol powered engine of any sort - be it wankel, flat, rotax (in this case), V6, straight 6, etc... whatever. It's simply the fact that hydrogen must be injected in a different manner to petrol, in the same way diesel engines differ their injection method from petrol engines. Hope that helped ;)

[serresjio]

what is the mass/power ratio?

[omarolon1]

You are the man!

[slypsi]

Wouldn't efficiency be increased by having higher injection pressure?

[roggerfrogger2]

@slypsi no because more pressure = more molecules in the same area, therefore your using more fuel

[DonHoraldo]

ok put whats the compression from hydrogen.

[rockysk8er]

what does over revving mean?

[Hewkll]

Do you think it's possible to use hydrogen engines in boats/ships?

Could you somehow convert the water into hydrogen and use it for the engine?

I know YouTube isn't exactly the right place for a scientific discussion, but would it be possible?

[atruerushfan]

The New Flyer H40LFR is a hybrid hydrogen fuel cell Bus.

It can be used as an engine, but there are not very many Hydrogen Pump Stations, and fuel cells are expensive and fragile.

[RDBRiguy]

You'd probably need to rid the water of salt and purify the water before you could even begin to convert it to hydrogen.

[Jupiterironman]

What is the liter per minute consumption rate of hydrogen of these cars???

How much liters per minute of hydrogen do these cars use in normal driving???

The device on my motorcycle produces over 40 liters per minute of hydrogen from water.

The device on my motorcycle also produces over 60 liters per minute of HHO gas. Is this enough hydrogen to run these cars??? Signed Norman Williams XMARINE. No joke!!!

[animetodamaximum]

I have many engine concepts but most I come up with are too expensive for the average consumer.

[devomax22]

well if you run nitrous in the hydrogen filter then you won't have as much speed as you would get out of dirt . so what i'm trying to say is don't use hydrogen or water use dirt mixed with nitrous its much cheaper. and remeber check your 8th gear four stroke powerband

[somekiwidude]

would be better if the hydrogen was separated from water then goes into the engine so instead of having to fill the tank with hydrogen you can just fill it with water

that way it would be very cheap to run

[mikitymike]

as far as i know an easy way to remove the hydrogen from the water is through electrolysis. and someone will have to pay for that electricity

[steamporsche]

In this system the prepressure (read:energy)of the hydrogen will be lost. Isn't it a better idear to inject the hydrogen directly into the cilinder at T.D.C.?
