The Running Resistance of Automobiles on Road Surfaces Covered with Snow

Abstract

In snowy districts, provided the road surfaces are covered with snow, the running of auto-mobile often gets into trouble due to the increase of road resistance, which sometimes gives rise to problems such as augmentation of fuel consumption, overheating of engine, slip of driving wheels, shortening the lives of parts, and so on. For taking steps to solve these problems, it is essentially important to make clear the values of running resistance. In this report, the relation between the road resistance of automobiles and the snowfall on road surfaces is ascertained.
