Aero‐Engine Injection Carburettors

THE following article is an attempt to provide those unfamiliar with the subject with a review of the working principles and the reasons for the use of so‐called ‘injection’ carburettor equipment, which has in recent years come to replace the conventional suction carburettor on reciprocating aero engines. As an introduction to the arguments, to be developed later, it is necessary to state a few simple definitions of the basic requirements for any form of carburettor for use on these engines.
