Hirth HM 500
The Hirth HM 500 was a German four-cylinder air-cooled inverted inline engine developed from the Hirth HM 504 in 1938. Although developing the same output of the HM 504 (105 hp) and keeping the same capacity and bore, the HM 500 was a very different engine; the new HM 500 had a one-piece "closed" crankcase for simplified manufacture. The new cooling system reduced cylinder temperatures considerably (15 °C less), and the fuel consumption was also reduced. The HM 500 carried a twin-magneto instead of the two separate magnetos as on the old HM 504. All these changes made that the HM 500 resulted a 12% lighter than the HM 504 and the front surface 37% less than the previous HM 504.Flugmotor Hirth HM 500, Luftfahrt International Nr 6, Dec. 1974 Otherwise the HM 500 continued the typical Hirth use of built-up crankshafts and roller-bearings for crankshaft & connecting rods (Hirth patents) as well as magnesium-alloy crankcases which made Hirth engines so popular in the 193 ...

A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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".

Alfa Romeo 115
The Alfa Romeo 115 is 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 An aluminium alloy ( UK/IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal.

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. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fluid ...

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 Hirth HM 60, 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 m ...

Walter Minor
The Walter Minor is a family of four- and six-cylinder inverted inline air-cooled engines, developed under auspices of ing. Šimůnek and used on light aircraft. First produced in 1929, the Minor engines' family has an advanced design for the period and sports steel cylinders, aluminum heads and overhead valves, with identical bore and stroke of and , respectively. Typical power ratings varied from . After Walter concentrated on the turbine powerplants only, the production of piston engines has been transferred to the Avia Motors, Avia company that further developed the family, bringing fuel injection, as the Avia M-137 and M-337. Nowadays the smallest of the family, the four-cylinder carburetted Minor, is produced by a small company in the Czech Republic, while the M337 was available from the LOM Prague.

Menasco C4
The Menasco Pirate series are 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.

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 as production moved 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).
