The Guiberson A-1020 is a four-stroke diesel radial engine developed for use in aircraft and tanks.
Development of the Guiberson diesel engine started in the 1930s with the A-918 and A-980 which was first flown in 1931. It is a single-row direct drive nine-cylinder four-cycle engine. [2]
Production A-1020s and T-1020s were designed and sold by Guiberson and produced by Buda Engine Co. [2] [3]

The Phoenix was an experimental version of the Bristol Aeroplane Company's Pegasus engine, adapted to run on the Diesel cycle. Only a few were built between 1928 and 1932, although samples fitted to a Westland Wapiti held the altitude record for diesel-powered aircraft at 27,453 ft from 11 May 1934 until World War II. The primary advantage of the Phoenix was better fuel efficiency at cruise, by up to 35%.
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 Piaggio P.XI was an Italian 14-cylinder radial aircraft engine. The P.XI was a licensed derivative of the French Gnome-Rhône Mistral Major 14K produced in Italy. Isotta Fraschini also produced a version of the 14K called the K.14.
The Warner Scarab is an American seven-cylinder radial aircraft engine, that was manufactured by the Warner Aircraft Corporation of Detroit, Michigan in 1928 through to the early 1940s. In military service the engine was designated R-420.
The Walter Mikron is a four-cylinder, air-cooled, inverted straight engine for aircraft.
The Praga Hostivař D was a four-cylinder, air-cooled, horizontally opposed aircraft engine first produced in Czechoslovakia in 1936 but which enjoyed its greatest success after World War II due to the explosion in popularity of sports flying. A version for helicopters was produced post World War II as the Praga DH
The Alfa Romeo 115 was an Italian six-cylinder air-cooled inverted inline engine for aircraft use, mainly for training and light planes, based on the de Havilland Gipsy Six engine. Production totalled approximately 1,600 units. Derivatives of the 115 include the -1, bis, ter and Alfa Romeo 116.
The Alfa Romeo 121 was an eight-cylinder, air-cooled, inverted V engine for aircraft use produced in Italy. It was typically rated at 280 kW (380 hp).
The Hirth HM 508 was an air-cooled, eight-cylinder, 60° cylinder bank angle inverted-V aircraft engine built in Germany in the 1930s. It had a bore and stroke of 105 mm × 115 mm and developed 210 kW (280 hp) at 3,000 rpm.
The Alfa Romeo 110 was an Italian four cylinder air-cooled inverted inline engine for aircraft use, mainly for trainers and light aircraft. The Alfa Romeo 110 was based on the de Havilland Gipsy Major, with approximately 500 units produced. Derivatives of the 110 include the -1, ter and Alfa Romeo 111.
The Argus 411 was a twelve-cylinder, air-cooled, inverted-V12 aircraft engine developed by Argus Motoren in Germany 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 BMW X is a small five-cylinder radial engine for sport and training aircraft. Although this engine proved successful at several large-scale events in 1930, including that year's round-Europe flight, only a few were built.
The Lycoming R-680 is a nine-cylinder air-cooled radial engine, the first aero engine produced by Lycoming. The engine was produced in two types, the E and B series; both are essentially the same. The B4E was available in a trainer version with a front exhaust collector "ring" for use without cylinder air baffles. R-680 received Approved Type Certificate No. 42 on 4 Feb 1930.
The Packard DR-980 is an American nine-cylinder air-cooled aircraft Diesel engine first certificated in 1930. The engine was unpopular despite its economy and reliability due to the unpleasant nature of its diesel exhaust fumes and considerable vibration when running; approximately 100 were built.
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 Walter Pollux is a Czechoslovakian nine-cylinder, air-cooled, radial engine, built by Walter Aircraft Engines for powering light aircraft and that first ran in 1936. The engine produces 240 kW (320 hp) at 1,800 rpm.
The Lycoming DEL-120 is an aircraft diesel engine produced by Lycoming Engines using automotive technology and initially powering unmanned aircraft. Because the DEL-120 is a non-certified engine and is meant for military use only, there is no civil application of this engine.
The Pobjoy P was a British seven-cylinder, air-cooled, aircraft engine designed by Douglas Rudolf Pobjoy and built by Pobjoy Airmotors. It became the progenitor of the Pobjoy R/Niagara/Cataract family of small radial engines. A notable feature of the Pobjoy P was the propeller reduction gear which allowed the small engine to operate at more desirable higher speeds.
The Astro 7 was a seven-cylinder radial aircraft engine built by Isotta Fraschini in the 1930s.
