Hirth HM 504 A2
The Hirth HM 504 is a four-cylinder air-cooled inverted inline engine. The HM 504 was a popular engine for light aircraft of the 1930s-1940s, and it was used to power a number of Germany's trainer aircraft of World War II. The engine featured a cast magnesium alloy crankcase. The Hitachi Hatsukaze Model 11 was a Japanese licensed version.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

80 Octane
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fuel ...

Air-cooled Aircraft Piston Engines
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. In all combustion engines, a great percentage of the heat generated (around 44%) escapes through the exhaust, not through the metal fins of an air-cooled engine (12%). About 8% of the heat energy is transferred to the oil, which although primarily meant for lubrication, also plays a role in heat dissipation via a cooler. ''Air-cooled engines'' are used generally in applications which would not suit liquid cooling, as such modern air-cooled engines are used in motorcycles, general aviation aircraft, lawn mowers, generators, outboard motors, pump sets, saw benches and auxiliary power units. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head, where the coolant absorbs heat, to a heat ...

Hirth Aircraft Engines
Hirth Engines GmbH is an engine manufacturer based in Benningen, Germany. It is currently a part of the UMS Aero Group. Hirth began manufacturing aero engines in the 1920s, was taken over by Heinkel in WWII to develop the Heinkel-Hirth jet engines, and today specialises in small two-stroke engines for light aircraft and other applications. History Hellmuth Hirth and Hirth Motoren The company was founded by Hellmuth Hirth as Versuchsbau Hellmuth Hirth. The first commercial engine, the 4-cylinder inverted in-line HM 60, first ran in June 1923 and was sold from the next year. Its quality was extremely high and it formed the foundation of the business.Gunston, Bill (1998). ''World Encyclopaedia of Aero Engines'', 4th Edition. Patrick Stephens Ltd (PSL). The company was renamed Leichtmetall-Werke GmbH, Elektronmetall GmbH and eventually separated from the aero engine manufacturing to form Mahle GmbH as a manufacturer of light alloy engine components, specifically the magnesium ...

Menasco Pirate
The Menasco Pirate series were four-cylinder, air-cooled, in-line, inverted aero-engines, built by the Menasco Motors Company of Burbank, California, for use in light general and sport aircraft during the 1930s and 1940s. The Menasco engines came in both normally aspirated and supercharged forms, with the supercharged models exhibiting superior performance at higher altitudes, with a relatively small increase in dimensions and weight. The supercharged models had the ''S'' suffix added to their designation to show supercharging.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 122–24, Cypress, CA, 2013. Variants ;Menasco A-4 Pirate (also listed as Menasco 4A) :90 hp. ;Menasco B-4 Pirate :95 hp. ;Menasco C-4 Pirate (Military designation L-365) :125 hp.

De Havilland Gipsy Minor
The de Havilland Gipsy Minor or Gipsy Junior is a British four-cylinder, air-cooled, inline engine that was used primarily in the de Havilland Moth Minor monoplane, both products being developed in the late 1930s. Design and development The engine was a simplified and smaller version of the earlier de Havilland Gipsy. It featured only one magneto where dual ignition was normal for the Gipsy series of engines. A total of 171 engines were produced, including 100 built in Australia, production moving to that country due to the start of the Second World War.Lumsden 2003, p.136.

Blackburn Cirrus Minor
The Blackburn Cirrus Minor is a British four-cylinder, inverted, in-line air-cooled aero-engine that was designed and built by the Cirrus Engine Section of Blackburn Aircraft Limited in the late 1930s. Design and development The Cirrus Minor started life as a clean-sheet replacement for the original Cirrus and Hermes series of light aircraft engines. Design was led by Technical Director C. S. Napier, son of Montague Napier, and was already under way when in 1934 Cirrus-Hermes Engineering was taken over by the Blackburn Aeroplane & Motor Company and moved to Brough in Yorkshire."A New Small Engine", ''Flight'', 28 February 1935, pp.218-9."The 'Cirrus Major'", ''Flight'', 13 June 1935. Supplement. Napier remained Technical Director and, while he completed the development and initial sales of the Cirrus Minor and its larger stablemate the Cirrus Major, Blackburn kept Cirrus Hermes Engineering as a separate company (though without the hyphen in its name).

Alfa Romeo 115
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. Description The Alfa Romeo 115 series of engines closely follows the original de Havilland Gipsy Six engines in having one-piece Elektron casting crankcases with cover plates, steel cylinders, finned for cooling, and detachable aluminium alloy cylinder heads.
