Impact of Chainsaw Power on Fuel and Oil Consumption

This research was carried out in a selection stand of beech and fir, where logging performed with chainsaws different powers. Two 3.9 kW were used for work on one area, while the other applied tools combination smaller larger saw (2.5 kW). After logging, consumption energy products (fuel (gasoline motor oil mix ratio 50:1) chainsaw oil) measured each individual by method refueling. It found that power chainsaw, i.e., powers, significantly influences beech–fir mixed stand. By using instead two chainsaws, savings about 26% fuel 24% achieved. The prediction analysis (of lower higher power) (currently common mode work) stands an estimated volume 1 million m3 year−1, could be 54,000 L 19,000 oil. In monetary value, this is saving EUR 120,000 2,500,000 MJ year−1 energy.
