The 2si 460 is a family of in-line twin-cylinder, two-stroke, single ignition, aircraft engines that were designed for ultralight aircraft. [1]
The basic engine was originally designed and produced by ILO-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 460 is still in production as a Diesel/multifuel or gasoline industrial, marine and sport vehicle engine. [1] [2] [3] [4] [5] [6] [7]
The 460 is a conventional twin-cylinder engine that weighs 59 lb (27 kg) in its F35 aircraft version. The engine features single capacitor discharge ignition, piston porting, tuned exhaust system, one or two slide venturi-type carburetors, fuel pump, a cast iron cylinder liner, ball, needle and roller bearings throughout. The aircraft version was offered with cog belt drive or a gearbox reduction system. Starting is electric starter or recoil starter. [1]

The Hirth HM 60 was a four-cylinder inverted air-cooled inline aircraft engine designed in 1923 and first sold in 1924. The engine was of very high quality, and its sales success contributed to Hirth's rapid pre-war expansion. It was a popular engine for light aircraft delivering 80 hp (60 kW) at 2,300 rpm. Later Hirth engines built upon the HM 60's success and provided greater power with many of the same design features.
The Lycoming R-680 is a nine-cylinder air-cooled radial engine, the first aero engine produced by Lycoming. The engine was produced in two types, the E and B series; both are essentially the same. The B4E was available in a trainer version with a front exhaust collector "ring" for use without cylinder air baffles. R-680 received Approved Type Certificate No. 42 on 4 Feb 1930.
