I'm trying to understand the relationship between mixture, throttle, and engine temp. In this article from AOPA, it states
... a lean mixture of 16 to 1 is not going to burn as hot as a rich mixture of 8 to 1. ... an engine [runs] hotter on lean mixtures.
This seems in general contradictory but what I'm gleaning is that there are some instances in which a leaner mixture will result in a higher engine temp and other instances in which a richer mixture will. Perhaps this comes down to throttle?
Could someone clear up for me what are the "primary points" so to speak with regards to engine temp that I should be aware of?
Further, does there exist a general graph somewhere with mixture, throttle, and engine temp on the x, y, and z axes, respectively? I might expect to see local maxima at full lean, full rich, and stoichiometric and local minima at I don't know where.
