ALL gasoline engines burn gas above the Stoichiometric balance in a rich situation so the engine does not overheat (using the unburned gas as a coolant)
This has always been the situation, and usually the gas is very rich.
To better protect the valves and stuff.
I have wondered why engine designers have not figured out how to really take advantage of lean burning. The greater heat would give more power/heat IF they could figure out how to use it without melting down the engine!!!
