Is this shit for real!?
yes it is. and i can explain a bit how it finaly works. it's possible to mod
a usualy car-engine / generator-engine that it can handle hydrogen.
the main-function of the engine are still based on the otto-engine. a
explosion push the pistons and the engine goes running.
the default otto-motor/engine works with a mix of gasoline and oxygen. this
mix with will be sore by a ignition plug. and nothing other happends in a hydrogen-engine. except that you have another fuel in your combustor.
the main-mods you must made is to make sure your ignition plug is heavy powerful. the hydrogen will explode on a temp about 560 - 600 degree (C).
just let compare that temp with some other sorts of fuel:
gasoline (95-102ROZ) : 200-300 degree (C)
diesel fuel : 170 - 390 degree (C)
hydrogen : 560 - 600 degree (C)
the most engine needs a new software to handle the new sore time periode and much more. hydrogen hase more power but less energy. ok that's sound a bit confusing...
hydrogen engine is about 45% efficent, a otto engine about 38%. the hydrogen explosion is very fast and more powerfull at all. but you need more hydrogen
in the the combustor to reach it. this is because in hydrogen-gas you have
ever a higher oxygen part as you need for the engine.
in fact your engine-power decrease a bit if you use hydrogen.
it's a bit more stuff about diffusion velocity hydrothermal stuff. but i
think it's enough to understand how it's work.
the gas-tank. in your car is a gas-tank with a filler and a vent (to make
sure your gas-tank don't explode, if you where just on a gas-station and fill up to 100%, and than parking in the burning sun. (gasoline under high temp needs more space)
the hydrogen-gas must a closed system. the filler is a highpressure-vent and your gas-tank must handle -253 dregee (C) and 700 bar! pressure.
BMW has a build a car "BMW Hydrogen7" that can handle hydrogen. but after 17 hours the hydrogen in the gas-tank stats to vent-out. that means a half gas-tank of hydrogen can vaporize in 9 days. the storage of hydrogen (if your not produce it on your ride) is very difficult at all.
since a few years in germany the gas-stations starts upgrading that they can offer hydrogen to the costumers.
the bad news is, 90% of the hydrogen manufacturing happend during fossil
fuels. it's mostly natural gas here.
finaly some facts about this engine-concept:
since 1999 on the munich airport the company MAN drives with 3 articulated busses around the area.
also in berlin in 2006 (soccer worldcup) some busses with hydrogen were used
to transport people and player. the vehicles cover a distance over 8.500 km.
after that success on the soccer worldcup they become a regular deployment on the berlin bus-masstransport. 2009 the project was canceled. the fixing costs raise to high.
1999 BMW build the 750hL car. the first concept car with hydrogen engine. it reaches a vmax of 225 km/h from 150kW (204hp).
2006 BMW presents at the los angeles car-show the BMW 760h "Hydrogen 7" car.
as a customer and could lease the car. no buy, only lease (it's like the EV1 story pls google it if you don't know: GM EV1 - a very good e-car from 1996-1999 with many fans but rejected by oil-lobby)
2009 BMW announced to stop building cars with hydrogen engines. that takes no car of the research, so BMW is still on it.
