The Mazda Rotary Engine Part 1
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the
Rotary engine works with comparisons to the Piston Engine. Also shows the
Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or
110S). Originates from the late 60's.

Rotary Rotational Demonstration
A little video for all those folks that refuse to accept the "3:1"
principle of planetary motion inside the Mazda Rotary Engine.
EDIT: For you people that are hung up on my comment at the end of the
video, I suspect you are probably one of those at which the comment
It never ceases to amaze me how many people will see this video and
continue to argue that there is some other relationship other than 3:1
between the inside and outside worlds of this motor.

Experimental Rotary Engines: Model 32
This follow-up to my previous videos summarizes the current design for the
benefit of those that are experimenting with Model 30 based engines. Model
32 is not yet finished but most of the mechanics are in place. It's been
dry run & tested for compression, friction & wear. Performance so far is
superior to Model 30. Completing the control electronics & firmware will
require more time.
Model 32 is similar to Model 30 (previous videos) except that: the rotors
are steel lined with graphite; the vanes pivot (rather than slide); vane
engagement is electronically controlled; seals, accuracy & fit are
improved; parts count & reciprocating masses are reduced; rotor phase angle
is adjustable to provide expansion ratios approaching 30:1; compression
ratios are adequate for burning vegetable/diesel oil using direct fuel
injection; the Lexan cover is replaced by a dimensionally more stable
aluminum reinforced plate glass. Fins will be routed into the exterior body
as needed for cooling. I should finish evaluating Model 32 by fall '07. The
next design (Model 33) inherits much from Model 32, except that it uses 1
rotor & 2 vanes.
The purpose of this open source program is to develop more fuel efficient
ICE's capable of operating on a variety of fuels for the benefit of our
environment, our economy & our future. This material is offered freely in
the hope that it may be useful & inspiring to tinkerers world-wide wishing
to improve Internal Combustion Engine technology. -Dave
