UPM BioVerno has been tested in Euro III class bus engines at VTT and in field tests carried out on Volvo Euro VI class buses in collaboration with the Helsinki Regional Transport Authority (HSL) and VTT. St1, Volvo and the transport company Transdev Finland are also participating in the field test process.
In the tests carried out at VTT, the tailpipe emissions of UPM BioVerno were compared with emissions from paraffinic fuels on the market and from regular fossil diesel.
Laboratory tests were carried out on Euro III class buses, which are still commonly used. Compared to regular diesel, UPM BioVerno diesel clearly reduced the amount of nitrogen oxides (NOx) and particulate matter (PM), which are the worst pollutants in exhaust gases. The reductions in NOx and PM emissions (g/km) achieved using UPM BioVerno were at the same level as the reductions achieved using other paraffinic fuels.
Road tests with buses were conducted by Transdev Finland on a regular bus route between the city of Kerava and Helsinki, using four identical Volvo Euro VI Class buses that have low emissions levels and efficient engines. Road tests were performed on 20%, 50% and 100% UPM BioVerno diesel. According to the test results, UPM BioVerno diesel works very well in all blending ratios—just like the best diesel fuels—and fuel consumption is the same as that of fossil diesel. Altogether, the four buses travelled 400,000 km without any fuel-related incidents.
