Fuel consumption and CO2 emission in timber haulage on different types of roads

Timber haulage is the last phase of timber harvesting. Due to its characteristics, cycle operation, a lot of unloaded driving, high purchase price of truck, transport of small amounts of goods, high fuel consumption, timber haulage is the most expensive phase of timber harvesting. Also timber haulage has a lot of negative impact on the environment due to its high greenhouse gas emission, especially CO2 emission. The aim of the paper is to analyze fuel consumption of forest truck and trailer during timber haulage in comparison to longidutinal slopes of roads, types of roads and total vehicle mass. Fuel consumption is measured by CANBUS module and data was transferred via Fleet manager system from truck to registred server. Fuel consumption is analyzed by overlapping the positions of truck from GPS signal with maps of public and forest road, in the aim to connect data with types and slopes of the road. Mass of the vehicle is measured with integrated scales on the air cushions on the truck and trailer. Research were performed on public and forest roads placed in mountanious and hilly regions. CO2 emissions are calculated based on fuel consumption data on different slopes and types of road.
