Use of more volatile fuels containing ether would be more likely to
result in a detonation event instead of a controlled burn. Have you
ever heard a Diesel started on "easy start"?
CI model aircraft engines don't use injection and don't run on White
Diesel or SVO. They can't be made very small like the Baby Cox. Due to
size, weight and vibration don't work well at large sizes so won't
scale up to vehicle engine size. Good for endurance records as much
more economical than glow fuel engines.
To use a air/fuel charge on a vehicle diesel engine would demand much
more heavy and robust engine construction.
A LPG fumigated "Diesel" may well be able to rev higher as the Diesel
is used as an ignition source for what has become a carbureted engine.

In a Model engine Veg oil just turns to black shit. It is running on
kerosene (Jet fuel), naphtha, cetane improver (a nitrate) with no
ether.
Tractors that ran on kerosene (TVO) were not Diesel as they heated the
fuel so it vaporised and could be ignited by a spark.
