The Aeromarine B-90 is an aircraft engine built by the Aeromarine Plane and Motor Company in 1915. Aeromarine made two series of V-8 engines. The B series was developed by Joseph Boland and the L series by Charles F. Willard. [1] [2] [3]

The Curtiss OX-5 was an early V-8 American liquid-cooled aircraft engine built by Curtiss. It was the first American-designed aircraft engine to enter mass production, although it was considered obsolete when it did so in 1917. It nevertheless found widespread use on a number of aircraft, perhaps the most famous being the JN-4 "Jenny". Some 12,600 units were built through early 1919. The wide availability of the engine in the surplus market made it common until the 1930s, although it was considered unreliable for most of its service life.
The 12Z, designated Type 89 by the company, was the final evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model had just entered production when France fell to the Germans during World War II. A small number were produced during the war but the German occupation government would not allow full-scale production to start. After the war small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development.
The Lycoming XR-7755 was the largest piston aircraft engine ever built in the United States, with 36 cylinders totaling about 7,750 in³ (127 L) of displacement and a power output of 5,000 horsepower (3,700 kilowatts). It was originally intended to be used in the "European bomber" that eventually emerged as the Convair B-36. Only two examples were built before the project was terminated in 1946.
The Klimov M-105 was a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.
The Klimov VK-107 was a V-12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.
The Allison V-3420 was a large experimental piston aircraft engine, designed in 1937 by the American Allison Engine Company.
The Hall-Scott A-7 was an early liquid-cooled aircraft engine manufactured by the Hall-Scott company of Berkeley, California. Using a straight-4 configuration, the engine developed 90 horsepower (67 kW) as the A-7 and 100 horsepower (75 kW) as the A-7a. In service these engines suffered from reliability problems and were prone to catch fire while in operation.
The Junkers L 5 was a six-cylinder, water-cooled, inline engine for aircraft built in Germany during the 1920s. First run in 1925, it was a much enlarged development of the Junkers L2.
The Klimov M-103 is a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.
The Kinner B-5 was a popular five cylinder American radial engine for light general and sport aircraft of the 1930s.
The Avia M 337 is an inverted six-cylinder air-cooled inline engine. It was developed by the Czechoslovak company as a six-cylinder derivative of the four-cylinder M 332 engine, going into production in 1960. An unsupercharged version of the M 337 is designated as the LOM M137. Production transferred to Avia in 1964, and to Letecke Opravny Malesice (LOM) in 1992.
The Daimler-Benz DB 602, originally known as Daimler-Benz LOF.6, was a German diesel cycle aero engine designed and built in the early 1930s. It was a liquid-cooled upright V16, and powered the two Hindenburg-class airships. It has roughly the same displacement and weight of the Beardmore Tornado, which was used in the ill-fated R101, but has almost twice the power of the Tornado, showing Daimler-Benz's superior knowledge regarding diesel engine construction.
The Wolseley 60 hp or Type C was a British liquid-cooled V-8 aero engine that first ran in 1910, it was designed and built by Wolseley Motors. The engine featured water-cooled exhaust ports and employed a 20 lb (9 kg) flywheel. During an official four-hour test the engine produced an average of 55 horsepower. A larger capacity variant known as the 80 hp or Type B used an internal camshaft and propeller reduction gear.
The Potez 4E is a French air-cooled flat-four piston engine of the 1960s. It was unveiled at the 1959 Paris Air Show, entered production in 1960 and is rated at 78 kW (105 hp). It remained in production until 1965 when Potez abandoned production of aero-engines.
The Hirth HM 512 was a 12-cylinder development of the earlier, 6-cylinder HM 506, produced in the late 1930s. Both were supercharged, inverted V, air-cooled engines.
The KFM 112M is a four-cylinder, four-stroke, dual ignition, horizontally opposed aircraft engine designed for ultralight aircraft and motor gliders.
The Aeromarine 90 hp was the first aircraft motor built by the Aeromarine Plane and Motor Company in 1914. In that year, Aeromarine had acquired the patents and manufacturing rights to the aircraft and engines of the Boland brothers. Although the Boland brothers didn't make a 6-cylinder engine, their V-8's all used the unusual concentric valve that is used in this engine. In spite of its model name, this engine only produced 85 hp (63 kW) at 1,400 rpm
The Aeromarine K-6 is an aircraft engine built by the Aeromarine Plane and Motor Company in 1915. It is an Aeromarine 90hp with a .571 reduction gear. The addition of the reduction gear allowed the engine to produce more power by operating at a higher RPM. This engine made its peak power of 100 hp at 2000 rpm
The Aeromarine B-45 is an aircraft engine built by the Aeromarine Plane and Motor Company in 1915. The B-45 shares the same bore, stroke and valve configuration as the B-90, except in a 45° Vee configuration. The other primary difference are cast aluminum cylinders in place of the B-90's cast iron resulting in a 40 lb (18 kg) weight savings.
The Mathis Vega 42 was a 42-cylinder 6-bank in-line radial piston engine, designed and built in France, by Société Mathis Aviation in the late 1930s, with development continuing during and after WWII.
