Any of you here familiar with Liquid Piston engines? Would the diesel variant be theoretically better suited to burn fuels like veg oil compared to an OM606?

Any thoughts or ideas on this.

Turbine engines are where it's at for fuel flexibility.

There is a lot of science that goes into combustion engines.

Diesel engines have higher compression ratios (historically) as they used the compression as the ignition source. Sometimes the fuel needed to be heated with glow plugs to combust in cold temperatures.

I bet you can find out of date books covering the subject of fuel mechanics.

Turbine engines are great, but they aren't suited for low revs. Also they won't have the fuel economy and are most likely harder to make than a Wankel or Liquid Piston engine.

Wankel engines are a great intermediary between turbine and piston engines, but they have the problems with their apex seals wearing out. That brings us to the liquid piston engine, basically and inverted Wankel.

I wonder if these LP engines are easier to make than a piston engine and more simpler to put together. If there are no piston rings and valve system, that makes it much easier to assemble, less worries about the fuel gumming up anything, and overall lighter.

Less moving parts means less things to fail. Usually it also means less variation for inputs and outputs.
