Some causes of black smoke:
Air in injector pump
Restricted return lines
IP timing to far advanced usually with loud combustion noise
Excessive fuel delivery due to weak injectors
Low fuel pump pressure
Clogged air inlet

basicaly black smoke is the partilly burned fuel for whatever reasons you have it its because there is more fuel then air one other one not mentioned is a worn out engine on its way out i know this since my uncle runs a harvesting company and he uses all 6.9 7.3's mostly idi's a few powerstroke 6.0s and 7.3s but its mostly the idi and they know that when it starts to miss and blow smoke when at higher rpm its on its way out
