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.

Rho, Lombardy Comune in Lombardy, Italy

Rho is a town and comune (municipality) in the Metropolitan City of Milan in the Italian region of Lombardy, located about 14 kilometres northwest of Milan.

Design and development

The B22 series are all four-cylinder four-stroke, horizontally-opposed, 2,203 cc (134.4 cu in) displacement, liquid-cooled, gasoline engine designs. They all employ single electronic ignition systems and have a compression ratio of 10.4:1. [1]

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.

Variants

B22D
Direct drive model with an output of 95 hp (71 kW) at 3300 rpm [1] or 100 hp (75 kW) at 3500 rpm, or 135 hp (101 kW) at 4700 rpm. [2]
B22G
Geared model with a mechanical gearbox reduction drive with a reduction ratio of 1.731:1 or 1.958:1 and an output of 122 hp (91 kW) at 4000 rpm, or 135 hp (101 kW) at 4700 rpm, respectively. [2]
B22L
Model with a mechanical gearbox reduction drive with a reduction ratio of 1.73:1 and an output of 115 hp (86 kW) at 3950 rpm. By March 2018 the engine was no longer advertised on the company website and seems to be out of production. [1] [2]
B22R
Model with a mechanical gearbox reduction drive with a reduction ratio of 2.14:1 and an output of 130 hp (97 kW) at 4700 rpm. By March 2018 the engine was no longer advertised on the company website and seems to be out of production. [1] [2]

General characteristics

Components

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.
