THE controversy of fuel injection versus carburetion for aircraft engines has resulted in many papers being written, some of which claimed to prove the superiority of one system, some, the other, and some, that neither system was any good.
Such variety of opinions resulted from the fact that it is very difficult to obtain in the same engine satisfactory operating characteristics with both carburetion and fuel injection.
These authors, however, now have fuel-injection equipment that is completely interchangeable with carburetion equipment.
In this paper, consequently, they go far toward settling the controversy, for they present factual data on engine performance with carburetion and fuel injection applied to the same basic engine.
