      These people/companies are just trying to re invent the wheel. Certainly some clever ideas but they just make the simple combustion process more complicated. Only wankel engine got close but got its flaws compared to regular four stroke piston engine (oil consumpiton etc.) so even mazda gave up.

      Saab made a VC (variable compression) engine twenty years ago! It moved the cylinder head closer and further from the crank though.

      Wouldn't the liquid piston vibrate like crazy since it's spinning an unequal non circular part

      The second place one is a convoluted mess, meanwhile the first one is elegant as hell.
      Though ultimately all of these are obsoleted by these weird engines that only pass electrons through them and produce no tiny explosions whatsoever.

      "more efficient than a wankel rotary", that's right up there with claiming better efficiency than a newcomen steam engine. When you're picking a very inefficient thing to compare it to, it's easy to claim massive increases.

      Before anyone claims that the wankel is efficient, it's only on the power to displacement that it did reasonably. When you look at how much fuel the things used, they're anything but efficient.
