Rotax 912

The Rotax 912 is since the early 1990s, a widely used engine for light, ultralight aircraft and motor gliders by the Austrian company Rotax.

History

Development of the 912 began in 1984, the certification was followed five years later. By the time he became the standard engine UL class. End of 2011, the 40- thousandth of the 912 engine family was delivered.

Description

It is a petrol -powered four-cylinder four -stroke piston engine with low-mounted camshaft, liquid-cooled cylinder heads, air cooled cylinders, hydraulic valve clearance compensation, non-contact magnetic capacitor dual ignition and built-in electric starter.

The engine also has a dry sump forced lubrication and two carburetors, mechanical fuel pump and a flanged with overload clutch propeller gearbox, which reduces the speed between the crankshaft and the propeller. The engine is not suitable due to its structural design for aerobatics.

It will be built in the variants 912 A / F / UL with 80 HP, 912 S / ULS 100 hp and 914 with 115 hp, the latter engine is a turbocharged variant.

Specifications

Development

The original Rotax 912 was initially without mechanical change by mounting a turbocharger to the Rotax 914 The Rotax 914 turbo engine proved to be sensitive and prone to failure, however, allowed for excellent flight performance in even greater heights (up to at least 6000 m or FL200 ). The proven Saugmotorkonzept the Rotax 912 has been further developed by increasing the bore and thus the displacement space to the Rotax 912S, without having to rely on complicated and error-prone technique of turbocharging.

March 8, 2012 912 iS presented at BRP Powertrain Gunskirchen the Rotax that has a fully electronic, redundantly designed ignition and injection system. This evolution of the engine according to the manufacturer has a 20% lower fuel consumption for the same power ( 100PS ), as the disadvantages, however, are increased by about 7 kg, a higher price and a slightly lower maximum torque against. The engine display for the cockpit is also connected via a redundant CANaerospace data bus system and is in addition to the engine data a variety of status information of the engine are available. As a cockpit display is a Engine Management Unit ( EMU 912iS ).
