"A characteristic / advantage of the (single) crankshaft PatOP (and PatPOC) is that the main bearings of the crankshaft are rid of loads. Theoretically you can keep the crankshaft by your hands during operation."
With the single crankshaft I believe this would also reduce friction and increase efficiency over conventional designs.
"Think about the rev limit and the power density."
Rev limit would be far higher and power density enhanced compared to current conventional designs.
These are both very desired enhancements to our current engine technology in our cars and other modes of transportation today. They pave the way for decreased engine sizing for reduced emissions while maintaining accepted power output of the modern vehicle.
Thanks for the great input and animation of your designs Manousos
I look forward to more of your posts and input in this important thread,
