Hi Paul.
Did was there ever version of diesel rotary? Thanks.

Not so far.

Is it possible for me to order a custom made rotor with compression
ratio of 18:1?
 I could come up with way to adapt pump and injectors to it.
The biggest concern with diesel is the turbulent of the combustion
chamber however. Do you think the rotor action can make complete
fuel burnt possible?  Do you see any draw back with a diesel rotary
base on the 13b?
Thanks.

Not possible. A depression in the rotor face is necessary to allow
combustion.

I have seen some racers partially fill the depression with a ceramic to increase the compression ratio.  Not sure how well that held up and I don't think you could get 18:1.  But it is something.

Back in the day when I attended tractor pull contests, I learned about high RPM tractor diesel engines that used low (8:1) compression pistons and three sequential turbos.  So the ultimate compression ratio was still very high - I suppose around the 18:1 range, however most of the compression was done externally prior to the "last stage" of compression by the piston itself.  I think the 4360 uses two stages and the 3350 as well?  Three sequential turbos on a two rotor would get heavy...

The CW R3350 was one super charge stage. Turbo compound would give the same BSFC with less structural
stress on the engine.
