The Rolls-Royce Merlin engine originally came with a direct carburettor, prone to cut-out due to fuel flooding in negative G. Beatrice Shilling Miss Shilling's orifice was a very simple technical device created to counter engine cut-outs experienced during negative G manoeuvres in early Spitfire and Hurricane fighter aeroplanes during the Battle of Britain.
Formed basis for the Rolls-Royce/Rover Meteor tank engine "Racing" Merlin; Racing engine for 1937/38 "Speed Spitfire" world speed record attempt. Merlin III with strengthened pistons, connecting rods, and gudgeon-pins, running on increased octane fuel, developed 2,160 hp (1,610 kW) at 3,200 rpm and +27 lb boost, a power/weight ratio of 0.621 lb ...
During the Battle of France and Battle of Britain in 1940, RAF pilots discovered a serious problem in fighter planes with Rolls-Royce Merlin engines, such as the Hurricane and Spitfire. When the plane went nose-down to begin a dive the resulting negative g-force would flood the engine's SU carburettor, causing the engine to
The Merlin 1B rocket engine was an upgraded version of the Merlin 1A engine. The turbopump upgrades were handled by Barber-Nichols, Inc. for SpaceX. [ 10 ] It was intended for Falcon 1 launch vehicles, capable of producing 380 kN (85,000 lbf) of thrust at sea level and 420 kN (95,000 lbf) in vacuum, and performing with a specific impulse of 261 ...
During inversion, fuel is delivered to the float bowl as fast as the fuel pump is capable resulting in an extremely rich mixture stopping the engine almost instantly. The problem was keenly felt by the RAF during the first years of World War II, because the Rolls-Royce Merlin engines fitted to Hurricanes and Spitfires suffered from the problem ...
The pintle injector is known to have caused throat-erosion problems in the early ablatively cooled Merlin engines due to uneven mixing causing hot streaks in the flow, however, as of 2021, it is not clear whether this is a problem that applies to all pintle-based engines, or this was a design problem of the Merlin.

The Packard V-1650 Merlin is a version of the Rolls-Royce Merlin aircraft engine, produced under license in the United States by the Packard Motor Car Company. [1] The engine was licensed to expand production of the Rolls-Royce Merlin for British use.
The two-stage Merlin engines had all of these features, which were designed to prevent detonation from charge heating and backfire into the supercharger. The G-series V-1710s installed on the F-82 E/F/G models had only anti-detonation injection (ADI) to deal with these problems, and not surprisingly had severe reliability and maintenance ...
