Hi, Repairman22, Thanks for your discussion on the split piston ICE. The main idea for it is the huge differences between the gas pumping exhaust and intake strokes and the heavy compression and power strokes for the ICEs. If we split these two functions the engine can run at 1/2 of the rpm for the same work otherwise it will produce 2x (actually 2.5 to 3 times torque). So the crawn section can be redesigned to run at somewhat higher speed with lighter system, since it just pump gases around. Basically, this design make an different hybrid of different kind. Other issues such as: 1. windows in the skirt is not away needed or just a litter cut is enough. 2. the cooling is much easier when stronger and thinner crown is used. 3.there is no oil leak issue if the piston rings are OK, 5. the "extra moving parts basically is the extra cylinder, i.e. i4 becomes v8 (or 2.5 to 3 time output), 6. The engines would run at half rpm, not the 1000rpm, 11. the push-down spring has the help by the the cylinder press at high rpm when the engine is loaded. The crown (piston-train) has about just a little high speed or the same depending upon what differential strokes are designed. The crown section is only to pump the gases around, which much, much lighter than the pushing the whole vehicle around.
