The Rolls-Royce Merlin engine of the British fighters had the drawback of being equipped with a float-type carburettor which cut out under negative "g" forces. The direct-fuel injected Daimler-Benz DB 601 engine gave the 109 an advantage over the carburettor-equipped engine; when an RAF fighter attempted to "bunt" (the diving entry into an outside loop) and dive away from an opponent as the 109 could, their engines would temporarily cut out for the duration of the negative-g forces. This ability to perform negative-g manoeuvres without the engine cutting out gave a 109 pilot better ability to disengage at will.
