RX7 Rotary 9000 rpm, engine blows, fire
This is not my video. I found it on an old hard drive I had from 2003,
before the days of youtube. Putting it up so everyone can witness the
abuse this rotary took before it finally gave up the ghost. If you don't
have 10 mins, it pops @ 7:17 and fire chaos begins shortly after.
Vane Rotary Engine (Scissors Action Engine)
This is the first ever actually WORKING internal combustion engine that
uses vanes in a so called cat-and-mouse motion. It is also known as
scissors action engine/mechanism.
There have been many attempts to create such engine (starting with
Stephenson who created the first steam locomotive), but all of them failed.
There are many challenges that have to be overcome in order to create a
real working engine of this type. To name a few: sealing, thermal
management, stresses in bearings and stresses in the cranking mechanism.
Many computer models do exist, and many nice computer generated animations,
but except for the design featured in this video, none has actually worked.
The only mechanism of this type that have been known to work, are
What is unique in the design shown in the video, apart for the fact that it
works, is its patented cranking mechanism. It is presently the simplest
mechanism capable of generating cat-and-mouse motion of vanes. Thanks to
its internal-external gear arrangement, the stresses in the gears are lower
than those in alternative mechanisms that usually use external-external
gear arrangements with multiple sets of gears.
There are other unique features in this design, to many however to discuss
in greater details here.
I hope you find this video and the engine interesting!
Gnome rotary engine startup
Startup and short run of a genuine Gnome rotary engine at the South
Australian Aircraft Museum. They have an engine run day twice a year and
startup a few old aero engines including this Gnome, a Rolls Royce Merlin,
a Pratt and Whitney radial, a few other radials, inline piston engines and
a jet or two. This one is my personal favorite.
The match of 7 second
Very fast. Mazda RX7 and Datsun 1200 Both with Wankel Rotary engine, with
turbo, in a 7 second match,
Salinas Speedway, April 8 2009, Salinas Puerto Rico.
Mazda RX3 (Godfather) & Datsun 1200 drag race.
Mazda RX3 almost hits the wall. The RX3 is known as the Godfather, it runs
a 20B rotary engine. The other car in the race is a Datsun 1200 ute from
Jett Racing, fitted with a Mitsubishi 4G63. Action was captured at Jamboree
2011 @ WSID (Western Sydney International Dragway) Eastern Creek, N.S.W.
