ncomplete if the combustion products contain any
unburned fuel or components such as C, H2, CO, or OH.
Insufficient oxygen is an obvious reason for incomplete combustion, but it is not the
only one. Incomplete combustion occurs even when more oxygen is present in the combus-
tion chamber than is needed for complete combustion. This may be attributed to insufficient
mixing in the combustion chamber during the limited time that the fuel and the oxygen are
in contact. Another cause of incomplete combustion is dissociation, which becomes impor-
tant at high temperatures.
Oxygen has a much greater tendency to combine with hydrogen than it does with
carbon. Therefore, the hydrogen in the fuel normally burns to completion, forming H2O,
even when there is less oxygen than needed for complete combustion. Some of the carbon,
however, ends up as CO or ju
