Please note that there on NO air compressed in this engine. Only the expansion of compressed air. The exhaust and intake ports have been modified to allow for two expansion ports to increase the efficiency of the expanding air. The exhaust is located in the typical rankle compression chamber where the fuel, air mixture is compressed. Placing the exhaust in this location almost completely removes losses due to compression. If you look at my other videos you will hear the engine so of course we d

Just to be clear, the design is to be air powered, not air cooled. Check my other videos to see the actual engine running off of scuba tanks regulated to 130 psi.

Hope this helps to clear up some of the confusion in the comments. Also, the engine is a modified sachs rotary from a snowmobile.

mazda is running an rx-8 hydrogen car since 1998 i think

Whats been modified? All I can see is a standard port rotary - for air you would duplicat the inlet and exhaust ports opposite each other as pressure in and pressure relief ports and you wouldn't need any of the fins for cooling either.

[YeTenuousUmbrae]

that's some elaborate cooling fins you have. extra weight/size would be too much.

btw, what is the fuel? air? :S

What is the modification?

@KLONIME1001 This response is as retarded as your writing. Google it and see for yourself. 

[tpvalley]

is the ratio of rotor speed to crank speed constant for all wankels or does it vary?

[coolfool182]

Did you do the graphics for this video? If so nice job, neat video. I love these rotos.

@klauskarlkraus We know :D

@HashECM guess you don't quite understand how compressed air works. The heat energy inside the compressed air in multiplied as it's compressed. That's what fires a diesel engine. The air in your air tools is on the other side and expanding, so it refrigerates a bit. Heats as it's compressed, cools as it expands.

@davespencer001

If it is powered by compressed air, why so much cooling?

3/4 of the tools in my shop are pneumatic - and the longer I run them, the cooler they get.

It is a function of a compressed gas to absorb energy when expanding.

Also, what is with the "spark" in the animation?

Additionally, the wankel design is horribly inefficent for expansion engines. There are 2 stage recip engines (French design) being used by Tata motors in India that are literally 1000% more efficient for this.

so you got rid of 50% of the fins......congrats, you accomplished nothing but a lack of heat exchange
