Changes in the external speed characteristics of chainsaw engines with the use of mineral and vegetable oils

Original language description

Similarly to many other countries, the use of biologically degradable oils in forestry is also addressed by the Czech law. Several studies point out several technical problems regarding such regulations. It has not been demonstrated so far whether for example biologically degradable engine oils used for power saw lubrication from mixture may be the cause for an excessive engine wear or deterioration of the combustion process and hence increased contamination of air inhaled by the operator. An experimental laboratory measurement was taken for the purposes of determining the external characteristics of the common chain saw engine at a brake stand which enabled exact measurement of differences in engine output, fuel consumption and composition of exhaustgases (CO, CO2, and HC), namely in dependence on the type of oil and the blending ratio. Results of the laboratory tests did not reveal any statistically significant differences between the oils in any of the measured criteria. The theory
