An information space is said to be "rich" if offers its users significant numbers of branches in a decision tree of non-trivial depth.

Refers to a condition in an internal combustion engine when the ratio of fuel to air in the intake charge is too high. A very rich mixture will usually not combust very well and over time can lead to fouled spark plugs (coated with soot) and engine head and piston crown carbonization. Excessive carbon buildup in the combustion chamber can lead to excessive detonation (knock).

One must pay close attention to the air/fuel stoichiometry in tuning modern engines for performance, as a rich condition can easily turn into a lean condition, and vice versa.
