  1. Looks a lot like some 1950's experimental engines. Dual diameter compressor piston and high pressure piston can use single bore. Limiting factors were always exhaust valve temperature and sealing any type of rotary valve. Sleeve valve engines are a very mature technology but have the same sealing issues. maybe new materials can help and may have been the basis of the FORD ceramic engine experiments in 1980's? You still need to somehow limit combustion temperature to lower the amount of nitrogen compounds produced though
