An on top of that hyrdogen is incredibly easy to compress. Honda's concept Hyrogen Fuel Cell vehicals had tanks which stored it at 5,000psi, and now they're working on 10,000psi.

I also don't know why you're saying that normal recipricating piston engines can't burn hydrogen? There have been quite a few in the past, including a Shelby Cobra which made over 400hp. Pretty much ANY engine can and already has run on hydrogen, and it has MUCH more detonation resistance then gasoline. The hyrodgen renesis is neat, but certainly not revolutionary.

How can you say that? Has there been any Hydrogen rotary's in the past? If not, I would say that's revolutionary, regardless of other "piston" applications.

There was one on the cover of Popular Science Magazine in '91 or '92.

Here is a sort of cropped picture of it.

Wait a sec.... I thought there wasn't that much room in the Rx8 engine bay to install a turbo in that position?

It's a differently setup motor than the RX8's

i always wondered why nobody used the factory OMP injectors for nitrous or some additional fuel...

anyone?

Mazda announced that there will be no fourth generation RX7. Making another RX7 would be as pointless as Nissan bringing back the 300ZX, despite the fact that they released the 350Z.

That makes sense since the RX-8's VIN has FE in it.

Thats not exactly what MAZDA said - They said there won't be another RX-7 (or any other rotary powered car) in the NEAR FUTURE (2005-6) BECAUSE the Hiroshima Renesis engine plant can barely keep up with the demand for the RX-8 and to bring out another Rotary engined vehicle it would have to sell enough to justify a major expansion of the Renesis engine plant.

Thats why Bill Gates needs to donate to Mazda's Rotary Research and Development.

Its not revolutionary because it dosen't take all that much work to make ANY internal combustion engine run off of hydrogen, or any other combustable fuel. The creation of the 4 stroke engine, or even Mazda's first working rotories was revolutionary, this is just a cool tweak.

OMP injectors, what are these as i'v never heard of them?

I guess that would explain why there are sooo many hydrogen powered engines out there then

Do a google search, there are!

I was working on a Gas Turbine Engine running made from junkyard parts running hyrdrogen last summer, but I never put enough time or money into it to get it going.

Oil lines that feed crankcase engine oil directly to the top of the rotor housing to lubricate the internal apex seals.

I have to wonder where exactly you heard that. I sat in a presentation by some Ford people on a Hydrogen powered Focus a couple years back at the SAE World Congress. I'm sure they'd be interested to hear that it won't work.

IIRC, they only managed a range of around a hundred miles on the thing, but it did perform about the same as a normal one. I don't recall too exactly, as I was only there to get a seat for the presentation immediately after it.

I have more pics of the engine, they are too big though doesnt want to attach let me delete this post ,hmm ill work on it sorry. The pics are ok, close up but through the display.

Here's something that has a beehive oil cooler, a turbo, and runs on propane. http://members.tripod.com/~mdavis19/turbine/

Hey every thisis my very first post.

I took a quick peek around and found this thread to be of most interest to me.

First off I'm very surprised and shocked at ALL of you within this site claiming that your ROTARY experts; which of no doubt you may be. However, I'm shocked that NO1 mentioned that this isn't new news in the sense that Mazda is the FIRST company to have a fully running hydrogen car since 1990 when they were testing for the Wankel Rotary 13-B engine!!! This was ackomplished with hardly any MAJOR changes to what went into the production RX-7 1993 model year.

Still though great photo, and I do hope to see more pristine modifications to existing RX-7 Twin-Turbo's and to the RX-8 of which I think the Nissan 350ZX has stolen its aftermarket potential thunder.
