Part 12: 13B Rotary Engine Rebuild - My 76 Mazda RX-5 Cosmo Restoration
Just as I promised last episode, it is finally time to build the engine! Part 12 of my RX-5 Cosmo restoration covers the entire process of building the 6 port 13B Mazda rotary engine. While this engine is a hybrid of GSL-SE RX-7 and Cosmo parts, the process is the same for any rotary from a 12A to a 13B NA, 13B turbo, 13B-REW or any other variant of the 13B. This video shows the whole process of the engine build, starting from measuring the rotors and covering everything else including clearancing the side seals, assembling the rotors, complete assembly the short block, setting the eccentric shaft end play and installing the front cover and everything underneath it. It's probably the most complete engine build video outside of what you can buy from the vendors, and as such, is an hour long. After this one, I'm going back to videos under 20 minutes. But for now, grab a beverage of your choice, sit back, and enjoy.





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.





PPRE 6 Rotor RX4 Track Test at the 2013 V 4 & Rotary North Island Jamboree (Onboard Footage)
Here's what you've been waiting for! The 2013 V 4 & Rotary North Island Jamboree saw the PPRE RX4 doing a test run on the Manfeild Park race track. Onboard footage turned out distorted because this thing is just so damn loud! Filmed and edited by Kaz Kostiuk-Warren. Be sure to subscribe for more. Music: T-Rex by Intercept.





Rotary Engine Breakthrough?
The Wankel engine always held out a lot of promise, but never was able to fully deliver on those promises. It was never very fuel efficient, and the Exhaust temperatures were very high. But now an independent car tech thinks he has stumbled onto what held that engine back. Get more video everyday at http://autoline.tv

Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom 4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs per rotor. It is also the first since the 787 to feature telescoping intake manifold. Custom made slide throttle body system. A world first however is the use of a center main bearing and 4-piece eccentric shaft. Quick specs- 9.7:1 rotors, lightened and race clearanced. Race main bearings, and race rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full custom Peripheral Port in each rotor housing (defined auto), Aluminum side housings for reduced weight. Needle roller bearing in the center housing. 4- Piece eccentric shaft 0:47 Dynamic engine balancing 1:23 Variable length intake 2:20 Engine assembly 2:32 Rotor rotation 3:49 Slide throttle 4:00 4-rotor startup and idle 4:30 All footage and editing was done by Defined Autoworks.

MAZDA RX7 Rotary Engine, How It Works
MAZDA RX7 Rotary Engine, How It Works https://twitter.com/#!/ADPEducation http://www.facebook.com/pages/Automotive-Diagnostics-and-Publishing/3669698 48008 The MAZDA RX7 rotary or Wankel engine is a marvel of engineering. It has won more races than any other vehicle in its class. Rotary engines develop a great deal of power for their weight (power to weight ratio). They're also able to develop high RPM bursts like no other internal combustion engine. Learn the details of it operation, how the rotor transfers power to the output shaft, what it the stationary gear set, what is the rotor to output shaft ration and relationship. Get all the specifics on the rotary engine's operation here in this video. Presented using advanced software CG animation technology to help you understand. Part of our Automotive Technology Rotary Wankel engines and MAZDA RX7-RX8 series shown here on this channel.

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

Libralato Engine
The Libralato engine is potentially the best small engine in the world; an eco-engine for the 21st century. The asymmetrical rotary engine is exceptionally compact, powerful, efficient, low emissions, low production and maintenance costs, low vibration and low noise. The engine is ideally suited for use as an onboard generator for the next generation of Range Extended Electric Vehicles (REEV) currently being developed by major manufacturers around the world, but is also suited for a wide range of mobile generator sets and other small engine applications.

MINH NGUYEN ROTARY PISTON ENGINE - R & D
All such engines have the potential to improve on the piston engine in the areas of: * Higher [[power-to-weight ratio]]s. _ Power (cv/rpm) _ Torque (Nm/rpm) _ Speed (rpm) * Mechanical simplicity. * Less fuel. While typically larger than the piston of an engine of corresponding capacity, a rotor may perform many [[stroke (disambiguation)|strokes]] per revolution. The MINH NGUYEN produces sixteen strokes (four power strokes per rotor rotation) per revolution of the rotor (four strokes per chamber times two chambers, and two times per chamber), as opposed to two strokes for each crankshaft rotation of a single-cylinder single acting piston engine, or a single rotor is in some ways equivalent to a eight-cylinder reciprocating engine (V8). 2[ http://www.youtube.com/watch?v=WPzPv-tT4BI ] Example of total capacity the same: 2(1.0 + 1.0) L = 4.0 L Or: 2[2(1.0 + 1.0)] L = 8.0 L MINH NGUYEN rotary piston engine has Just on center, then the Compressor gear and the Driving force gear are the Fly-wheels Accumulates kinetic energy (continuous and entire) Note: The Blocking rollers were reinforced by the electrical motors (or compressed air).
