Lots of hype on Diesels in airplanes, little action.

I wonder if the problem is the sharpness of the combustion event
destroying props?

Not at all.

The problem is that diesels are usually heavy as crap to withstand the
higher combustion chamber pressures that diesel engines have, mainly. The
other problem is that fuel pumps and injector systems used on diesel engines
usually will not work using jet fuel, which is the fuel these engines are
normally going to be using.

Of course, the largest problem is having the money it takes to develop an
engine and get it to market. Costs can be enormous.
