Has that type of piston/combustion chamber got a name? What's the advantage?

Still learnin'  :)

The Blackstone engines look way cool!  I would guess the combustion chamber is built that way so that the valves and seats can be removed from the engine for service and a working cartridge can be poped in in a matter of minutes.  If this is so what a great feature to keep the engine in service!              Leland
