The system controls the injection of fuel directly into the engine's crank chamber and also controls ignition timing to ensure that the combustion cycle is in tune so the engine performs optimally whatever the load and delivers higher torque over a wider speed range. Emissions are reduced thanks to greater combustion efficiency and the engine is also tolerant to varying fuel grades.
Users are promised 20 per cent greater performance than that of its predecessor. Power output is increased by 0.7kW and the saw's increased torque means that it is unaffected by feed pressure and forges ahead to produce a quick and even cut.
In addition, the advanced technology makes a choke redundant. Monitoring both external and internal engine temperatures and adjusting its own settings to suit, there is only one "on" position and no more fiddling between warm and cold starts. The start procedure is reduced to flicking the switch, purging the engine and pulling the starter cord.
A further benefit of the fuel-injection system is felt in lower vibrations by enabling the use of a lightweight piston, which results in less oscillating mass inside the engine cylinder.
