Matthias Stark

Matthias Stark serves as Professor of Energy Systems Engineering at the Institute of Thermal and Fluid Engineering, School of Engineering and Environment, FHNW University of Applied Sciences and Arts Northwestern Switzerland (Windisch) since 2020. Previously, he was Team Leader for Future Technologies at Winterthur Gas and Diesel (2016-2020) and Research Engineer at Wärtsilä Ltd (2005-2016).

His research spans combustion diagnostics, tribology/rheology, and advanced measurement/sensor technologies for energy systems. Key areas include lubrication systems in marine diesel engines, oil film thickness measurement via ultrasonic methods, injector design optimization, and the impact of alternative fuels on engine tribology and emissions. He integrates experimental methods with theoretical analysis to enhance engine efficiency and reduce environmental impact.

Analysis of his recent publications shows a consistent focus on large two-stroke marine diesel engines. His work addresses tribological challenges under new fuel regulations (e.g., sulfur cap 2020), develops real-time optical sensors for lube oil, and optimizes lubricant flow to reduce particulate emissions. The research combines numerical simulation, experimental testing, and advanced diagnostics.

Stark is an active member of the Institute of Thermal and Fluid Engineering at FHNW, where he leads research in energy systems and teaches courses including thermodynamics, heat transfer, and advanced experimental methods.
