Control of CI Engines for Efficient and Robust Biomass Utilization

Utilizing the biomass derived fuel in CI engines in the most efficient manner is the focus of this work. Since the fuel can dramatically change the combustion and the biomass conversion process is for a specific fuel, both aspects must be examined. How tailor made fuel properties can be used to optimize engine and exhaust gas aftertreatment efficiency and reduce harmful pollutants will be studied, and feedback and learning control methods developed. Understanding of exhaust gas sensors and their use for engine control to changing conditions and (bio)fuels. The properties of promising fuels and how this affects the biomass to fuel conversion will be considered by working with collaborators.
