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.

Contents

The basic engine was originally designed and produced by JLO-Motorenwerke of Germany and was later acquired by the AMW Cuyuna Engine Company of Beaufort, South Carolina and marketed under the Cuyuna brand name. Later the engine was marketed by Cuyuna under the Two Stroke International (2si) brand. Cuyuna no longer markets engines for aircraft use although the 230 is still in production as a diesel/multifuel or gasoline industrial and marine engine. [1] [2] [3] [4]

Germany Federal parliamentary republic in central-western Europe

Germany, officially the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

Beaufort, South Carolina City in South Carolina, United States

Beaufort is a city in and the county seat of Beaufort County, South Carolina, United States. Chartered in 1711, it is the second-oldest city in South Carolina, behind Charleston. The city's population was 12,361 in the 2010 census. It is a primary city within the Hilton Head Island-Bluffton-Beaufort, SC Metropolitan Statistical Area.

Development

The 230 is a conventional single-cylinder engine that weighs only 36 lb (16 kg) in its A20 version. The engine features single capacitor discharge ignition, piston porting, tuned exhaust system, slide venturi-type carburetor, fuel pump, a cast iron cylinder liner, ball, needle and roller bearings throughout. The engine was offered with cog belt drive or a gearbox reduction system. Starting is electric starter or recoil starter. [1]

Capacitor discharge ignition

Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making the ignition system more suitable for high engine speeds. The capacitive-discharge ignition uses capacitor discharge current to the coil to fire the spark plugs.

Carburetor device that mixes air and fuel for internal combustion engines

A carburetor or carburettor is a device that mixes air and fuel for internal combustion engines in the proper air–fuel ratio for combustion. It is sometimes colloquially shortened to carb in the UK and North America or carby in Australia. To carburate or carburet means to mix the air and fuel or to equip with a carburetor for that purpose.

Variants

General characteristics

Components

  • Valvetrain: piston porting
  • Fuel type: Minimum 92 octane
  • Oil system: premixed oil and fuel
  • Cooling system: air-cooled
  • Reduction gear: cog belt or optional gearbox
Valvetrain mechanical system that controls operation of the valves in an internal combustion engine

A valvetrain or valve train is a mechanical system that controls operation of the valves in an internal combustion engine, whereby a sequence of components transmits motion throughout the assembly.

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.

Performance

  • Power output: 20 hp (15 kW) at 6000 rpm

Aircraft diesel engine

The aircraft diesel engine or aero diesel has not been widely used as an aircraft engine. Diesel engines were used in airships and were tried in aircraft in the late 1920s and 1930s, but never widely used. Their main advantages are their excellent specific fuel consumption and the somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines. The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in the early 2010s.
