carburetor icing
carburetor icing[′kär·bə‚red·ər ‚ī·siŋ] (mechanical engineering) The formation of ice in an engine carburetor as a consequence of expansive cooling and evaporation of gasoline. carburetor icing The most common form of engine icing, which is caused by a sudden drop in temperature resulting from vaporization of the fuel and adiabatic cooling following the pressure reduction as the air accelerates through the venturi of the carburetor. The ice gradually builds up and blocks the venturi, upsetting the fuel-air mixture and resulting in a loss of power. |
