Complete and incomplete.
Combustion is a reaction, correct? Take this classic combustion reaction: CH4 + 5O2 -> 4CO2 + 2H2O. In technical terms, combustion is only complete if all the methane and all the oxygen are used up in the reaction. In practical terms we consider combustion complete if all the fuel gas converts to CO2, so we provide an excess of oxygen.
There are two kinds of incomplete combustion. The first is when we provide enough oxygen to convert all the carbon to either CO or CO2. (We don't worry about the hydrogen - that element is so reactive it's going to grab oxygen first and leave the carbon to fend for itself.) The second is where we provide so little oxygen the carbon doesn't get a chance to react. This is where soot comes from.
