 The fuel injected Daimler-Benz DB 601 engine gave the 109 an advantage over the carburettor-equipped engine; when RAF fighter attempted to "bunt" 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.On the question of comparative turning circles in combat, Spitfires and Hurricanes benefited from their lower wing loading compared with the Bf 109
