Bullets and pistons are round for a reason. Highest volume for surface area, mating surfaces expanding and contracting at the same rate. Easy to seal and long lasting.

Now get rid of the reciprocation costs, valve train costs and minimize the heat losses to the cylinder head and manifolds by using the exhaust to preheat the intake, combined with a single injector and inlet port for combustion events and you're speaking my language.
