Stihl MS500i Fuel Injected

The MS 500i is the world’s first chainsaw to feature electronically controlled injection. The innovative STIHL Injection technology guarantees optimum engine performance and excellent starting characteristics, regardless of altitude and ambient temperature. Sensors measure air pressure and internal and external temperature, and pass information on to the control unit. This can use the identified values to determine the optimum fuel quantity and ignition timing. As a result, fuel metering is assured through the opening and closing of the valve. STIHL Injection is therefore synonymous with rapid acceleration, extremely high power, and low weight:

the chain accelerates from 0 km/h to 100 km/h in 0.25 seconds.
The MS 500i achieves the best power-to-weight ratio on the market: an unparalleled 1.24 kg/kW.
Electronically controlled fuel injection takes place in the tried-and-tested STIHL 2-MIX engine, which offers high performance with low fuel consumption. The petrol chainsaw features STIHL ElastoStart to protect your muscles and joints. Its HD2 air filter, captive nuts on the sprocket cover, controlled-delivery oil pump, tool-free fuel cap and side-mounted chain tensioning complete the premium features.
