Your role

You will be part of the Efficient Powertrain Solutions (EPS) Research group working on several challenging projects, at the forefront of research and development of novel combustion engine technologies. With over 40 researchers and 3 MEUR of annual research turnover, we are the biggest focused powertrain-oriented research group in Finland. Our focus is on model-based development of advanced engine solutions supporting our industry partners in conforming to tightening emissions and noise regulation in marine and off-road sectors.

Hydrogen represents a promising zero-carbon alternative fuel for large oceangoing vessels, where internal combustion engines are expected to remain a prime mover. Hydrogen-biogas combustion is a green solution in marine application, where the methane slip in exhaust gases is challenging to remove by catalytic and thermal management methods, which require further development. Methane is counted parallel to CO2 as a greenhouse gas, which emissions are regulated. In addition, significant challenges have restrained its large-scale onboard integration, catalyst durability, amid concerns related to safety, fuel availability, and cost. This research is related to green shift in off-road applications (marine, machinery), where conventional fossil fuels like diesel oil will be replaced with low-/zero-carbon fuels with flexible mixtures.

The new EU-funded [H4PERION](https://www.uwasa.fi/en/research/projects/h4perion-hydrogen-performance-enhancement-and-reliable-ice-operation) project directly addresses these barriers by developing a new ultra-efficient hydrogen-capable internal combustion engine (TRL 7, while meeting 55% thermal efficiency target), followed by concept integration at ship level through a pilot demonstration.

In this context as a part of the EPS team, you will contribute to:

• Developing novel catalytic methane removal solutions securing low pollutant emissions and flexible operation with hydrogen and other gaseous fuels.
• 1D modelling and simulations of catalytic aftertreatment systems based on engine-out emissions and experimental catalyst performance results.
• Experimental catalyst testing campaign in corresponding off-road application.
• Integrating the exhaust aftertreatment systems together with appropriate thermal and energy management strategies to ensure compliance with the projects emission and efficiency targets.

Achieving the targeted efficiency within the project timeline requires deep integration of catalyst simulation and testing environments with autonomous calibration routines. To this end we are seeking talented and motivated researchers in simulation-driven catalytic aftertreatment development and optimization.

All tasks are agreed in more detail in the Annual Work Plan. The annual working time is 1612 hours.

Requirements

• You have a masters degree or a PhD in a relevant field. For example chemical/mechanical/process engineering, with a specialization in emission catalyst reaction reactions/modelling or combustion engines.
• You have documented experience in 1D aftertreatment/combustion model calibration and validation with experimental data. Experience in 3D simulation environments is a benefit.
• You are able to efficiently plan and conduct engine laboratory experiments and postprocess emission data. Laboratory experience such as test-rig development, instrumentation, and data-acquisition is considered a strong advantage.
• Engine emission aftertreatment involves chemical reactions, as a result good knowledge on catalysts as well as chemical reaction mechanisms and kinetics is a benefit.
• Excellent analytical skills in addition to good academic writing skills are highly advantageous for your candidature.
• Proven track record in high-quality journals/conferences/projects on the topics related to the position, is an additional advantage.
• You enjoy developing innovative solutions to technically challenging problems and have the right mix of intellectual curiosity and practical pragmatism.
• You have good communication and language (English is required) skills and enjoy working both independently and as part of a team. You are open to sharing your knowledge with colleagues and ambitious to develop yourself as a researcher.

To be eligible for a full PhD student position, the candidate is required to participate in a separate application process which is arranged at least twice a year in order to be admitted and enrolled as a doctoral student at the University of Vaasa.
