Sauer Flugmotorenbau (Sauer Aircraft Engines) or "Sauer" is a German manufacturer of aircraft engines based at Ober-Olm in Germany.
The first certified 4 stroke engine entered the market in 1987. The 4 stroke engines are certified according to CS-22 Subpart H [1] for use in motorgliders, CS-LSA [2] and CS-VLA [3] type of aircraft. They also makes engines for use in ultralights and Homebuilt aircraft. The production consist of 4 stroke engines based on VW "Type 1" engines (commonly known as air-cooled beetle engines) and based on the later Volkswagen Wasserboxer engine. Sauer also makes 2-stroke engines. [4] There have been development of a turbocharged 2 cylinder 4 stroke engine based on the Weber MPE [5] "recreational engine" in 2009-2010, but no commercial available engine exists to date. [6]
There are two main versions of the boxer 4-stroke engines. Those with the casing of air-cooled beetle engines, and those with the largely similar, but stronger Wasserboxer casing used in late VW vans before the Volkswagen Transporter (T4).
Even though the Wasserboxer engine is water-cooled, this involves only the cylinders and the top. The casing has no water lines, it is only stronger built. This makes it possible to convert the Wasserboxer "back" to an air-cooled engine. The benefits of this conversion is the added strength, and the size of the Wasserboxer casing will accept larger cylinders. In general it becomes a much more robust engine compared with engines using the original air-cooled casing. [7] These "water to air" converted engines are sometimes referred to as the misnomer oxyboxer in automobile VW engine circles.
Various engines from 14.9 to 100 HP, single cylinder to 3 cylinder. [4] These engines are re-branded Hirth engines built by Sauer. [8] The specifications are identical to the corresponding Hirth engine.
The naming format changed in 2003. The current naming format is: S aaaa-(b)-(XYZ)c
Whereas the old naming format found in older engines is: [13]
There is no defined naming for these engines from the manufacturer, but they all are named according to:
Limbach Flugmotoren is a Chinese-owned company based in Germany that produces aircraft engines.
The Rotax 912 is a horizontally-opposed four-cylinder, naturally-aspirated, four-stroke aircraft engine with a reduction gearbox. It features liquid-cooled cylinder heads and air-cooled cylinders. Originally equipped with carburetors, later versions are fuel injected. Dominating the market for small aircraft and kitplanes, Rotax produced its 50,000th 912-series engine in 2014. Originally available only for light sport aircraft, ultralight aircraft, autogyros and drones, the 912-series engine was approved for certified aircraft in 1995.
The Jabiru 3300 is a lightweight four-stroke, horizontally opposed "flat-six" air-cooled aircraft engine produced by Jabiru Aircraft. The engines are direct drive and fitted with alternators, silencers, vacuum pump drives and dual ignition systems as standard. The engine is used to power homebuilt and ultralight aircraft.
