A Predictive Study of the Occurrence of Meteorological Conditions Contributing to Automotive Carburetor Icing.

Abstract

Meteorological conditions contributing to automotive carburetor icing were examined for 338 first order weather stations located in the continental U.S. and Alaska. Automotive carburetor icing, resulting in poor warm-up and stalling, occurs due to several factors; namely, critical engine and carburetor design, fuel volatility, and the occurrence of specific meteorological conditions. For this study the frequency of the simultaneous occurrence of an air temperature between 35 to 45F and a relative humidity greater than 74 percent was determined for each hour of the day at each weather station. The highest hourly percent occurrences are displayed in isopleth maps for each month, with their intended application for defining geographical regions where automotive carburetor icing is likely to occur.
