Does anybody know of any experimentation into using non-circular pistons and bores? For over a century engine designers have relied heavily on the standard cylindrical piston/bore combination. I do know some makers have had experimented briefly with oval pistons (notably Honda's NR engine) but there have been few follow ups.
It would seem that modern day manufacturing techniques would open the door to a wide range of designs that were difficult/impossible to build in the past. So what do you guys think? What are the Pros and Cons of deviating from the norm? Also what other shapes show promise?
