Another deeply flawed engine

[RodRico]

The whole premise of this engine is the efficiency gained by combusting in a spherical chamber, but heat transfer doesn't occur only during combustion, and this engine has a cubic chamber during compression and expansion with significantly higher surface area than a cylinder. I'm also at a loss as to sealing efficiency, friction, how it's cooled, and how one pipes fuel to an injector moving with RPM. Did I miss anything?

I love these Solidworks engines, and that one is a beauty.

It is like trying to improve the wheel. There is the Wankel, and Turbine, if you don't want pistons in an ICE, all way simpler than that example. Sealing that combustion chamber would be a mess.

Beautiful mechanics but will never run except on a monitor.

This engine looks like it will have very high wear and tear due to the matter that it would be very hard to lubricate. The matter that the double acting cylinders in steam locomotives could not really be lubricated is part of what killed the steam locomotives. That was 1 aspect of the wear and tear problem with a lot of engines not just steam locomotives.

Actually, Otto cycle engines had very high wear and tear problems until a metallurgist who worked for Henry Ford discovered that adding a very small amount of vanadium to steel extended the life of engines by leaps and bounds. This reduced the wear and tear problem to a practical and affordable level.

I also suspect that some parts of this engine are violating the Pauli Exclusion Principle which is the quantum mechanical application that no 2 solid objects can occupy the same exact space at the same exact time. Autodesk Inventor allowed me to do that so that I would not need to draw an ACME threaded rod in Parametric CAD class. The only screw forms that were available were the 60 apex angle threads no Acme no Whitworth threads.

This engine is good for a laugh.
