Summary:

Carburetor icing is considered as a twofold problem consisting of cold-stalling during the warmup period, and throttle restriction due to ice formation at highway cruise conditions. A simple engine test method is described whereby test or reference fuel samples are continuously metered upstream from the throttle plate. Through suitable interpretation of time-rate-of-rise of induction vacuum, conclusions are drawn regarding the resistance of fuel compositions and gasoline additives to both forms of carburetor icing.These conclusions are based entirely upon equivalent concentrations of a reference alcohol mixture in a gasoline of known throttle-icing characteristics. The characteristics of alcohol as a carburetor icing inhibitor are discussed, and typical data are presented to illustrate the effects of a surface-active type gasoline additive on carburetor icing. In each case, an evaluation of the important influence of atmospheric humidity on test ratings is included. A survey of the throttle-icing characteristics of a group of commercial winter gasolines provides an estimate of the utility of anti-icing additives in current marketing practice
