Italy republic in Southern Europe

Italy, officially the Italian Republic, is a country in Southern Europe. Located in the middle of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates San Marino and Vatican City. Italy covers an area of 301,340 km2 (116,350 sq mi) and has a largely temperate seasonal and Mediterranean climate. With around 61 million inhabitants, it is the fourth-most populous EU member state and the most populous country in Southern Europe.

Aircraft engine Engine designed for use in powered aircraft

An aircraft engine is a component of the propulsion system for an aircraft that generates mechanical power. Aircraft engines are almost always either lightweight piston engines or gas turbines, except for small multicopter UAVs which are almost always electric aircraft.

Rubiera Comune in Emilia-Romagna, Italy

Rubiera is a comune (municipality) in the Province of Reggio Emilia in the Italian region Emilia-Romagna, located on the Via Emilia about 50 kilometres (31 mi) northwest of Bologna and about 13 kilometres (8 mi) southeast of Reggio Emilia.

Design and development

The engine is a three-cylinder in radial-configuration, four-stroke, 2,238 cc (136.6 cu in) displacement, liquid-cooled, gasoline engine design, with a mechanical gearbox reduction drive with a reduction ratio of 1.91:1. It employs dual electronic ignition systems and has a compression ratio of 9.0:1. [1]

Radial engine reciprocating engine with cylinders arranged radially from a single crankshaft

The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant.

Reduction drive Device, containing a different gears.

A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears.

Compression ratio the ratio of the volume of a combustion chamber from its largest capacity to its smallest capacity

The static compression ratio,, of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity. It is a fundamental specification for many common combustion engines.

General characteristics

Components

  • Fuel type: gasoline
  • Cooling system: liquid
  • Reduction gear: mechanical gearbox
Propeller speed reduction unit

A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant. This allows the use of small displacement internal combustion automotive engines to turn aircraft propellers within an efficient speed range.
