The Hirth F-36 is a single-cylinder, two-stroke, carburetted aircraft engine designed for use on ultralight aircraft, especially powered paragliders and ultralight trikes. It is noted for its extremely small equipped weight of 280NaN0 including exhaust system, reduction drive and carburetor. It is manufactured by Hirth of Germany.[1]
The F-36 was formerly known as the Solo 210, before the design was purchased by Hirth.[2] [3]
The engine uses free air cooling, single capacitor discharge ignition, with a single integral pump-type carburettor. The cylinder walls are electrochemically coated with Nikasil. Standard starting is recoil start with electric start optional. A quadruple V belt reduction drive system is an option with ratios of 1.8:1, 2.0:1 or 2.5:1.
The engine runs on a 50:1 pre-mix of unleaded 93 octane auto fuel and oil and produces 150NaN0 at 6000 rpm.
