Two-Stroke Wankel

Wankels are interesting engines, really. They use a 3-sided rotor that spins and kinda slams into the side to compress or exhaust gasses. The main problem with Wankels in sealing loss. They need seals to keep the cycles sealed in their specific chamber. The problem is that the seal must go from the extreme temperature of combustion straight to the cold temperature of intake and in the process they expand and contract, resulting in some seal loss.

We have scavenged piston engines, why not wankels? I propose a wankel engine that has rotary valves, much like the Coates Patented Rotary Valves (link). There would be two of them in each spot and they would be in the 2 places where the rotor is at its greatest expansion. This is because with the scavenged design, the place of combustion would change each time. Since by scavenging the exhaust and intaking all at once, this frees up an extra cycle. This means it can start the process over again that much sooner. This means there would also be sparkplugs in the two areas where there is the greatest compression.

So the wankel gets its intake and exhaust all in one, making it more efficient as both cycles individually are inefficient. It also makes more power since it would have twice the combustion strokes per every rpm. It also prevents seal loss due to temperature change because the fact that the intake and exhaust happen all at once and the fact that it varys each time mean that there is essentially no great temperature difference from cycle to cycle. And the rotary valves allow for variable valve timing so more control on low rpm and high rpm performance.
