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.

PAUT MOTOR-REVOLUTIONARY ENGINE.wmv
PAUT ENGINE - Prototype 2 is performed as an engine with two-sided pistons, positioned at 90° to each other, in combination with PAUT two-stroke cycles (fig 1). Such construction provides an engine containing less assembling parts, having smaller mass to power and overall-dimensions to power ratios, which are the presumptions for a successful product to be accomplished and for low cost production/exploitation to be expected. Smaller mass, compared to the prior art engines, derives from the fact that PAUT engine contains considerably less assembling parts lacking elements such as: rods, camshafts, camshaft's driving parts, some valves, large heads. The very construction of the two-sided piston (fig 3) has more advantages. Contact area between two-sided piston and cylinder is considerably larger compared to prior art pistons. Hence, specific pressures are lower and since the two-sided piston is lubricated under the pressure, the friction is considerably smaller, the more so as we know that normal force Fn in the engine center equals zero (fig 2a). All these results with less wear of the piston and the cylinder. Such a two-sided piston has considerably smaller mass compared to the prior art assembly it replaces, consisting of two pistons with their prison-shafts and two belonging rods, resulting in lessening of linear motion inertial forces. This construction has still more advantages as compared to prior art engines such as: - better controlled cooling of cylinders not being adjoined to each other - smaller friction inside the engine due to less moving parts - increasing the capacity of this engine, though considerably, results in overall dimensions to increase only slightly - gravity center is posted lower (it is in the engine center) - better forces configuration in the very engine, while negative forces and torques nullify each other completely (fig 2b) - it is possible to dismount pistons and cylinders without entire dismounting of the engine - no special tools nor machines were used to produce this engine - there is less noise due to the design of the two-sided piston - though the cycle is of two-strokes, the lubrication is performed as if it was four-strokes The objections on this construction should be as follows: - due to the compressed construction , the starter should be mounted on the gear box, but with some endeavour it is possible to mount it on the very engine - the force on the output journal of the crankshaft (fig 2a) is twice compared to the one at prior art engines, but this problem becomes negligible with a proper design of the journal and of the operating shaft bearings - there is no oil sump at this engine, hence an additional oil-pump is needed - since it is a two-stroke cycle engine, the engine cylinders are submited to higher mechanical and thermical load comparing to four-strike cycle Prototype 2 - characteristics (technical data): • Two-stroke engine • Engine-block measurments with heads mounted 500mm x 440mm x 440mm • Engine two-sided piston diameter 100 mm • Compressor two-sided piston diameter 120 mm • Two-sided piston stroke 88 mm • Capacity 7000 cm3 • Number of chambers 4(engine) + 4(compressor) • Number of two-sided pistons 2(engine) + 2(compressor) • Weight 135 kg • Power, torque and specific consumption have not been measured as yet.

save a mazda rx7 after 16 years "rx7 jungle"
this rx7 was abandoned since 16 years in a garden, after 1year of negotiation the old man sold with 50euro i start and take the road after 16 years, the car have 30.000km!!! but after 16years in garden the body is very rusty! i just take the engine, the rest is dead... thanks to watch my vidéo and comment ;) mazda rotary is a magic car! my forum: www.KamikazeNipponRacer.be (belgium) in french: cette rx7 était abandonnée depuis 16 ans dans un jardin,aprés 1an de négociation le vieux me l'a vendue pour 50euro,la voiture n'avait que 30.000km!! mais aprés tout ce temp dans le jardin la caisse était toute pourrie,je l'ai redémarrée et j'ai pris la route,je l'ai vendue juste pour le moteur merci d'avoir regardé ma vidéo et d'avoir posté un commentaire mon forum: www.KamikazeNipponRacer.be (belgique)





MAZDA RX7 Rotary Engine Failures
MAZDA RX7 Rotary Engine Failures MAZDA RX7 rotary engines are strong and displace a lot of power for their size. Traditionally, carbon deposits and heat are their biggest enemies. Rotary engines run with a huge temperature differential, meaning that one side of the engine runs cooler that the combustion side (side with the park plugs). As a rule, cooling system damage should be avoided at all costs. Learn how these issues affect rotary engines and what kind of damage is done to them when they really fail. 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.
