A rich fuel mixture is definied as being a mixture that is rich in fuel, which would make the engine run cooler. In the presence of a lean fuel mixture the engine will run hotter. This can be easily seen in the use of an oxy acetylene torch. You first set off the fuel alone, then turn on the oxygen. To get the torch to cut through steel you set the acetylene flow back until the flame generates a bright blue cone. A common issue with the use of nitrous oxide is a lean out condition in this same fashion which "torches" a hole through a piston in the same way a common torch does. So in conclusion a rich mixture will run cooler.
