Answer to Question #18930 in Inorganic Chemistry for Deepa
5. An automobile engine requires a carburetor
or fuel injector to mix the fuel with air. The fuel and air must be mixed in a particular
ratio to achieve maximum efficiency in the combustion of the fuel. What might happen
if the fuel and air mixture is too rich (if there
is too much fuel)?
If there is too much fuel (too rich), combustionwill not be complete, power will diminish, and carbon will quickly build up in the cylinder.
