TWIN RC Wankel Rotary Engine First Run!

22. des.. 2020
897 836 Ganger

The final part of the twin rotary engine. It uses 2 x O.S Wankel 49pi II engines. It has a great flaw at the moment which I'm going to fix it at some point. The eccentric shaft is not hardened. I made it out of ck45 steel. It's very durable and can be used as a shaft just fine. However the lobes, as well as the front and rear of the shaft, spin inside 4 needle bearings in total. That means that the shaft will be chewed by those hardened needle bearing material. I need to harden the existing e-shaft, which is the wrong method since it's in its final dimensions, or make it all over again. The process is as follows: Turning on the lathe leaving it slighltly overised, quenching and then grinding. I don't feel very confident about the last two, but I'll try it. Any ideas on what material can use to avoid the hardening and grinding? Something that can be turned only with carbide I guess.

  • a problem with Wankel engines is that the tips on the rotor wear out quickly and need to be replaced to keep compression high in the ignition chamber, they sprung loaded some tips to help with longevity but this problem along with its thirsty nature sidelined Wankles from mass usage in the auto industry, do you have the same problem, I.E. the tips wearing out quickly, in a car it makes the servicing of these parts to much hassle, the time involved is just too much, labour costs and downtime of the engine,

  • Johny I think your going need a bigger tank!

  • Anodize the irons man I know you can do it and they'll last alot longer. Great work though beautiful stuff please though fix your exhaust situation those 90° bends are so bad on an engine that relies on harmonics so heavily and I mean your work is so good that if you knew I'm sure you would've already haha. The day you make a 4rotor is gonna be amazing especially a boosted one and I hope that's where this is going

  • ***PLEASE TAKE NOTE*** I am very experienced and formerly a distributor of JUSTICE BROTHERS Automotive Products. They have a copyrighted element in all their products called "metal conditioner" with the machines you make you NEED a bottle of "HEAVY DUTY VEHICLE" or other Misc products with a lesser concentration and added oil base. But HEAVY DUTY VEHICLE specifically is PURE metal conditioner, this is a product that will cut your friction on contact surfaces to as little as humanly possible. With enough soaked into a full sized engine it can even run (for a while at least) with NO OIL AT ALL thats how effective it is. You have enough scaled engines you can absolutely prove what I'm saying. For $20, WHAT DO YOU HAVE TO LOSE? But I'm 100% positive from an insider's perspective it'll make all of your creations run longer, faster, more trouble free, with less wear. It stops metal from leaving the system. Instead of scraping and scoring on bearings and these rotary face plates you'll see it basically POLISHES anywhere that metal rubs metal, if area gets hot it's even more effective. I want you to put some in your little engines so when you take them apart it'll PROVE BEYOND ANY QUESTION what these products do. But as you rely on oil content in your fuels to lubricate you more than anyone could benefit the most from what they have to offer. If you have a hard time finding some to use on your projects Message me at I really enjoy your videos and can't wait to see how much better they'll work/longer they'll last!!

  • Turn it on the lathe a bit oversize, then send it out to be hardened by a company that does that. It could also be case hardened by them. Also- an American mechanic has come up with a new and likely better design whereby the rotor's combustion point indent is not located on the mid point between the two "corners" but is located more logically near the "corner" that is leading the spin. In this way the explosive "push" is out to one side like a push on a lever to give more force and to logically increase spin faster. He has not to my knowledge made this full size as yet, but it seems the first step would be to instead make a model to test it. YOU should be the first gut to do it. Naturally the ignition plug would have to be over on that side as well.

  • Usualy for shafts that endure a dynamic stress you use Steel with a bigger yield resistance. e.g. 42 CrMo4 maybe also look into those materials Not directly necessary but definitly futureproof

  • I don't believe that engines of this sort are made to be gunned like that, have you ever been in an airplane where the pilot did that? when considering the acceleration and deceleration of the internal parts is not a great idea. take the same scenario but with heavier internal parts.

  • How about making a "Liquid Piston" engine? I don't like the name but it cleverly swaps the rotor stator shapes. A flat oval rotor runs in a trochoid stator. The stator has three combustion chambers and it breathes via the rotor. It's under patent so working commercially would need a licence.
