This paper deals with the possibilities of minimizing the emissions of heterogeneous substances/pollutants (SO2, NOx and NCx) per volume unit of processed timber, based on measurements of the design and operating performance of a mobile off-road system working in the forest environment. The forest production system is taken to mean the production system into which the material and resource flow and/or even the workforce flow enter. During the production process the material, power and/or workforce flow is transformed into the final product (processed timber, soil preparation, afforestation, etc.). Operating and/or design capacity is the control variable optimizing the operating mode of the forest production system. The quantities of emitted pollutants related to the work unit done by the production system represent the criterional function specifying the optimization of parameters of the mobile off-road system working in the forest sector. The conditions for the operating mode (performance) of the mobile off-road system working in the forest environment under which the minimum emitted pollutants related to the unit of done work are reached have been determined. The theoretical conclusions have been verified experimentally.

Keywords: forest technology; SO2, NOx, NCx; optimizing; minimization
