Here are some pics of the single rotor RENESIS engines being built here in Australia for light aircraft and automotive use.





Havng the rotating assemble balanced.

Someone stare at those end housings and see if you notice what I notice. Those look like the 6 port end housings since there are 2 intake runners but upon closer inspection there is only 1 port in the plate. Strange? I think so!

 

Even the 4-Port motors have a recession where the auxillary ports go in the castings. That is what you can see in the pics.

 

I've never seen the inside of a 4 port Renesis before. They aren't even close to the old 4 port engines in terms of intake timing or location. Just a 6 port without the other 2 ports really. That severely limits any power upgrades for the 4 port engines.

 

Yeah but they are great for turbocharging :D

 

 

So... Gokart or motorcycle motor?

 

Interesting article, though they seem more concerned with controlling emissions, rather than power output. Which is probably a good thing, since that's probably why we don't have another rotary platform yet.

 

I have seen a few mfr. making single engine rotary engines for light, experimental aircraft. I think one of those aircraft 1-rotor engines was used by the TN contingent to power a golf cart seen at DGRR (in 2017).

 

What they did fails wrt emissions and I don’t think they fully understood why. With two 6-port end plates on a 1-rotor creates a four port intake; two secondary and two open auxillary ports, and two full exhaust ports. The timing of those open auxillary ports is not going to favor that. Had they used the early AT 4-port end plates to create a 2-port 1-rotor it likely would have produced better emissions results.

With their 4-port 1-rotor sec/open-aux port configuration though, add a turbo with E85 and the proper support components for high boost and I see the potential for a compact, lightweight 300-350 whp zoom-zoomer for competition purposes. A company in Australia already makes an intake manifold for it that has all four intake port openings cast, but a thin casting blank over the auxillary port inner passages that allow you to either use the 4-port AT housings for a 2-port 1-rotor engine or grinding out the auxillary blanks and use 6-port end housings for a 4-port 1-rotor configuration.

However, for a 4-port 1-rotor turbo engine you don’t need either an SSV or VDI. So imo it’s possible to take a 6-port LIM, cut the center part out and weld it back together in such a way to retain the factory AUX actuation. Then just weld in a common plenum to tie it all together. Alternatively, just leave them open, which without sleeves possibly provides for more flow potential, with the understanding that the low end performance is impacted.

Somewhere else I saw a Renesis 4-port 1-rotor mock build with a 13B GSL rotor housing to provide a 3rd peri-exhaust port, but that might be too much except for ultra high boost/power attempts.

Just some interesting stuff I’ve been studying lately ...
