Is altitude a problem?

I suppose that's the reason you don't see diesel powered piston engine aircraft although I believe I did read that, I'm thinking Honda, is working with a diesel aircraft engine. That would be interesting.

Just looked it up, it's DeltaHawk that has the diesel aircraft engine, Honda has jet engine for business class.

Yanmar 3TNE84 - Direct Injection-Self Bleeding (thankfully...) with a standard Manifold Air Heater, why?

BTW - Doesn't air get denser as it get colder anyway (molecules get closer together)?

Theilert and SMA also make Deisel aircraft engines. Not many of then in the USA yet, but they're getting there.

The Deltahwk Diesel aircraft engines are turbocharged. I'm not sure about the others, but wouldn't be surprised if they are as well.
