Type 4 mechanical compression ratio, Why is the factory compression so low? Options

[Beebo Kanelle]

OK, here's a fun one for the novice to ponder and you experts to answer:

Why is the factory mechanical CR so low?

and for reference, what is the highest mechanical CR that can be physically achieved? assume no octane limitations -

I'm just looking for the design limit for the highest CR that can be / has been in a Type 4 engine using available technology.

Thanks

That's the beauty of the freedom of free will,doing it your own way.
Every new idea has come about that way.
Thomas Edison's lightbulb,he did it by ignoring self tooting critics.
Wright brothers did it their way too.
Sikorsky was told many times to stop wasting his time.
Rickover sailed right past all the bs.
Elon Musk too is doing it his way,the sound of the bs talkers lost in the roar of the rockets.
One thing in common with all these achievers is the words can't or won't are meaningless.
So go ahead,do what you like,build your new Acme,and define your own future.

Yes, but all those guys didn't just think and talk about it...they did it !

BTW Edison didn't invent the light bulb, he bought the rights and his team made the first practical incandescent light bulb.
