The engine is a turbocharged four-cylinder, four-stroke, horizontally-opposed, 1,352 cc (82.5 cu in) displacement, gasoline engine design, with a mechanical gearbox reduction drive with a reduction ratio of 2.54:1.
The Rotax 915 iS is an Austrian aircraft engine, produced by Rotax of Gunskirchen for use in ultralight aircraft, homebuilt aircraft, light-sport aircraft, small helicopters and gyroplanes. The engine was type certified in 2017. [2] [3] The engine was first publicly displayed at AirVenture in July 2015 [2] and first flown in March 2016. [4]
It is the rate of fuel consumption divided by the power produced. In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2. It may also be thought of as power-specific fuel consumption, for ...

The fuel consumption per mile or per kilometre is a more appropriate comparison for aircraft that travel at very different speeds. [citation needed] There also exists power-specific fuel consumption, which equals the thrust-specific fuel consumption divided by speed. It can have units of pounds per hour per horsepower.
The Rotax 914 is a turbo-charged, four-stroke, four-cylinder, horizontally opposed aircraft engine with air-cooled cylinders and water-cooled cylinder heads. It is designed and built by the Austrian company BRP-Powertrain, owned by Bombardier Recreational Products (BRP), as part of its Rotax brand.
In 2016 the design set an FAI Class R (Microlights and paramotors) world speed record for absolute speed of 323.82 km/h (201 mph) with a standard Rotax 912 engine. [8] For this record the pilot Alberto Porto, who is also the CEO of Swiss Excellence Airplanes, received an Oscar from VFR Magazine [9] and the De la Vaulx Medal by the FAI.
