"The fundamental basis of the concept is well proven by the historic “sleeve-valve engines,” in which the cylinder sleeve briefly but rapidly rotated as the engine approached top dead center.

But the unexpected after effect was nearly 10 times less wear, plus better fuel economy. Unfortunately, modern-era pollution regulations prevent the sleeve-valve engine’s resurrection. Thankfully, one significant feature of it, the moving/rotating cylinder and its associated benefits in friction and wear, is about to make a big comeback".
