This document is the O.S. engine instruction manual, mainly introduces the basic components of O.S. engine, safety use precautions, installation methods, use methods, maintenance methods and other contents
This manual provides instructions for the O.S. 49-PI Type II, a rotary combustion engine based on the NSU/Wankel System. It details the operating principle involving a three-lobe rotor and an epitrochoidal bore, distinguishing it from conventional reciprocating engines. The document emphasizes safety warnings regarding the high-speed propeller, flammable fuel, and carbon monoxide exhaust.
| Engine Type | Rotary combustion engine |
|---|---|
| System Basis | NSU/Wankel System |
| Fuel Type | Methanol-based model engine fuel |
| Oil Content | More than 18% |
| Nitromethane Content | Between 5% and 15% |
| Glowplug Type | Type F |
| Carburetor Type | Type 21G |
Use top quality methanol-based model engine fuel containing more than 18% oil, either synthetic or castor, and between 5% and 15% nitromethane.
No, it is suggested to start the engine with an electric starter because hand starting can be difficult due to the fuel mixture not having direct access to the glowplug.
Model engines exhaust deadly carbon monoxide, so they must never be operated in an enclosed space.
Warm the engine to approximately 20°C before attempting to start it.
