    Description of the Engine, Mounting Instructions and Technical Data 1.1. Overview The S650R engine (Figure 1.1.1-1) of Sauer Flugmotorenbau Gmbh is a two cylinder in-line two-stroke liquid cooled engine. The cylinders consist of an aluminium alloy with a Nikasil coated running surface that is highly resistant to wear.

    Figure 1.1.2-1 (Dual Dellorto Carburation System) 1.3. Description of the Ignition System The ignition system (Figure 1.3-1, 1.3-2) consists of an armature plate, a magneto, E-Box(s), ignition coils and the ignition cables with the required number of spark plug leads. The ignition system is completely electronic and possesses an E-PROM for a freely programmable ignition curve however, this can only be carried out by the manufacturer.

    Installation instructions 3.1. Mounting and securing the engine The six screw threads (M10) located on the underside of the S650R engine crankcase is for fastening the engine to a suitable engine mount. Figure 3.1-1 (Fastening thread points) The engine should be mounted so that the moment from the engine to the mounts can be absorbed as widely as possible.

    Figure 3.3-1 (Fuel-diaphragm pump with impulse connection) The positioning of the fuel tank over the engine is advantageous as would ensure a reasonable fuel supply pressure. It is recommended to maintain a consistent fuel pressure under all conditions. Additional monitoring of fuel pressure by means of a fuel pressure gauge may also be considered. When installing the fuel tank beneath the engine, the maximum fuel line length between the fuel tank and diaphragm pump should not exceed 2,000mm.

  • Page 10: Monitoring Apparatus

    4.1. Exhaust gas temperature A gauge that we recommend on all Sauer two stroke engines is the Westach Exhaust Gas Temperature gauge (EGT) as in figure 3.2.1. This gauge is a reliable measurement tool that measures the exhaust gases as they exit the engine.

    tighten up the clamp. As an option, manifolds are provided to suit the "bayonet probe" type. The terminal cable can be lengthened to a maximum of 4.5 metres without affecting the accuracy of the instrument. Route all wires away from the manifold and other heat sources. Support the wires every 300mm intervals, using tie wire or similar.
