LIGHT PLANE ENGINES and Their FUEL PROBLEMS 420096
HE recent revision of gasoline specifications is presenting a serious problem for designers of light airplane engines, where the customers are demanding increased power at no increase in cost or weight. The author points out the effects of using fuels of higher octane number containing greater proportions of lead, and describes attempts to alter the engine design to permit the use of higher leaded fuels without seriously increasing the weight or cost of the engines.
The use of dual carburetion, the author believes, on a 6-cyl opposed type of engine is the simplest method of approach for the time being. However, he points out that the designer of the light plane must better appreciate the necessity of better cooling and attention to details in the installation, in order to do his part in obtaining fhe maximum efficiency from the engine.
