Internal Combustion Engine Laboratory and Fuel Laboratory
The Internal Combustion Engine (ICE) and Fuel Laboratories at the University of Vaasa form a unique research environment for developing future low-emission engine technologies and studying renewable fuels. In addition to basic engine performance parameters, the laboratories enable analysis of fuel combustion, measurement of various gaseous emissions, and determination of particulate emissions—both in terms of number and mass. The measurement equipment is comprehensive, and the university also utilizes modeling and simulation software for studying engines and energy production systems. The laboratories provide research services for companies, research institutes, and other universities.
The Internal Combustion Engine (ICE) Laboratory includes several research engines, such as Wärtsilä’s single-cylinder W20 engine, the W4L20 engine, and AGCO’s single- and four-cylinder engines, along with a comprehensive electrical and automation system. The W4L20 engine is loaded by an ABB alternator that generates electricity for the Vaasa power grid. The engine is controlled using a model-based Speedgoat control system, and an ABB frequency converter enables operation at variable speeds. The exhaust system is designed to allow the integration of various exhaust cleaning technologies.
The Fuel Laboratory is a research facility specializing in the analysis of liquid fuels. Its goal is to support the energy transition and enable the testing and validation of future fuels. The laboratory works closely with the ICE Laboratory and regional chemical laboratories. Its analysis methods include viscosity, density, oxidation stability, and elemental composition. In addition to research projects, the laboratory provides customer services ranging from single analyses to larger projects. Ask for more information: fuellab@uwasa.fi.

Geoenergy Laboratory
Within the Geoenergy Laboratory, there is mobile research equipment suitable for various field measurements. The DTS measurement device (distributed temperature sensing with fibre optics) has been used to study heat transfer, for example, in sediment and asphalt fields. The TRT carriage has been constructed for testing the thermal response of boreholes and other shallow geothermal sources. These mobile research devices enable on-demand research anywhere in Finland.
