What made the Merlin engine so good?
But well-designed liquid-cooled engines like the Merlin could run for long periods beyond normal operational limits without overheating, as liquid cooling is more efficient than air cooling, particularly for the cylinder head and valves. And they could operate at higher altitudes, reducing risk from anti-aircraft fire.

Why was the Packard V-1650 Merlin engine made?
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. The engine was licensed in order to expand production of the Rolls-Royce Merlin for British use. The engine also filled a gap in the U.S.
What was the first aircraft to use the Merlin engine?
The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber.
How much pressure does a Merlin engine have?
One pound-force per square inch equals 2.036 inHg or 6.895 kPa, and a standard atmosphere is 101.325 kPa =29.92 inHg =14.70 lbf/in². In early Merlin engines the maximum manifold (boost) pressure was +18. This was increased in later models.
