Fair enough. If the thread isn't over I can have the mods move it. Which subforum?

Is this one more unicornish?
If there's no crank throw, why wrist pins in the pistons. Do three points of sliding friction and two planetary gear sets have less friction than one main bearing?

Definitely more unicornish, as it seems even more expensive to manufacture.

Even considering the piston pin as another point of sliding friction just like the main bearings, it would still sound more convincing than having to deal with 3 points of sliding friction and 2 planetary gearsets. Not to mention once again the need for more head gaskets and valvetrain parts as the engine would look more similar to a boxer on the outside. And even though this specific design doesn't seem to be so much more optimized for an oversquare bore-to-stroke ratio as the other, it would still make more sense to have fewer cylinders with a longer stroke from an efficiency standpoint. |

Change of venue at 4:12?
It's like an OK Go video with placeholder music.

I am enjoying this thread.
It isn't really Unicorn material, though practicality is in question.
I've always admired the Commer Diesel engines and remember them puttering around our barrio as a kid.

The Youtube algorithm has decided I need to see more of these.

Only a gentle nudge from an infinite force needed to change direction in an instant.

All that's needed is a three cylinder variant with 120° spacing.
Make it a radial and shorten the length of the crank- cam- shaft thingy.

I like how if you stall your engine or something at all out of the normal happens, your timing is shot?
