Adam Standley's Rotary Engine Apex Seal Design

[0okk]

Very ingenious, but would that not wear out the ends even faster than they would normally?

[KnightKadir]

very nice and true style of rotary engine, i think mazda should see it

[twistedengineering]

I would say get rid of oil injection and instead lubricate the rotor from within. The apex seals could be designed to work like piston rings where, like an oil ring, oil would be provided by channels through the eccentric shaft and forced out of the apex seal to lubricate the rotor housing walls. Also with your variable apex seal angle design, this would be much more doable because you can always provide adequate sealing with space for oil to pass through. Great design!!!

at speeds above 6or7000 rpm seals are less nessarty

[originalbrownirish]

how are u gonna keep those lubricated?

[Jamesbowman777]

I like the idea but a bit heavy and complex. I think Apex seals that angle backward from rotation using a small radius curve under mild spring tension could be bennificial. This should allow combustion pressures to give a proportianal increase in sealing pressure on the important leading apex seal. This is one of the problems with the wankel allowing unburnt hydrocarbons out the exaust leading to high fuel consumption and pollutants to escape.

good idea... however why not try a more simple crankshaft design instead using a Scotch yoke type mechanism? I'm thinking about a well known piston - crankshaft configuration.. the seals work exactly as the piston in a conventional piston engine...the motion is controlled by 3 such seals interconnected with a transmission chain.. A similar design to your own... I'll try to make a video when I have time

Trop complexe !

Ok, I think this design is nice. I want to make a hydrogen rotary and this design will improve the engine´s relaiblility. The only thing is that as also a car enthusiast, I think for performance this mod will not benefit the engine becuase I imagine that this needs extra lubrication and also has reciprical side effects on engines spinning at high rpms or abrupt rpm changes (exp. downshifting or with high boost going form 2500 rpm to 8500 rpm in less then a second).

[AdamStandley]

very true! There are certainly some practicality issues but it'd be interesting to build a prototype and see! Thanks for the feedback.

[eatdatpussy]

WOW, thats ingenious the way the apex seals conture so that they are perpendicular to the face of the rotor housing

I have a 13b turbo rotary engine in my gen 2 rx7..

you can test any prototyes on my engine you want! like, seriously

[AdamStandley]

thanks man--you can test my first prototype if I ever get any money!

[lazzer408]

Whats the problem with the exhisting apex seal? Why change it's angle?

[fuhrercat]

man i thought about something like that for the rotary only using a small piston with the same arm design to give the engine more torque, i also thought about changing it so instead of it firing 1st rotor and 2nd rotor on one side i thought 1st rotor on left and 2nd on right for more thermal efficency

[AdamStandley]

Indeed, I have designed other models with pistons or centered in the face of each lobe or preferably elastic faces that can change curvature --all this intended to increase the compression ratio (efficiency). The disadvantages, however, would be sealing issues and perhaps some chatter or other issues arising with materials operating on two oscillating systems (rotation from the rotor and reciprocation from crankshaft)..as usual the more moving parts, the more problems.

[fuhrercat]

ya true, even a simple piston set up would throw the rotary to the front of the pack in engine design, but even staggaring the firing order/pattern, would also create a more thermal efficent engine, and could also create more torque (maybe) but it would all be re-routing the intakes and such
