Carburetor Air Temperature

The temperature of the air as it enters the carburetor. It is important that the temperature of the fuel-air mixture be kept above the freezing point of water to prevent the formation of carburetor ice, but it is difficult to measure the temperature of this mixture. By measuring and controlling the temperature of the air as it enters the carburetor, it is possible to keep the mixture temperature high enough to prevent water condensing out of the air and freezing, and at the same time to keep the temperature of the air entering the engine low enough to prevent detonation.
