Diesel has the highest energy content of any affordable commonly avaible fuel.
Its only dirty if you when you burn it at lower air fuel ratios.
Gasoline does the same thing in lower A/F ratios.
If you were to fumigate the intake of the diesel with natural gas or methanol, replacing diesel fuel energy with natural gas or alcohol it would run much cleaner.
