Journal ArticleDOI
Energy security matters in the EU Energy Roadmap
Daniel K. Jonsson,Daniel K. Jonsson,Bengt Johansson,Bengt Johansson,André Månsson,Lars J Nilsson,Måns Nilsson,Måns Nilsson,Hannes Sonnsjö +8 more
TL;DR: In this article, the authors screen and scope out a more comprehensive suite of energy security aspects to be considered when assessing low-carbon energy scenarios and apply it using the EU Energy Roadmap as an example.
Journal ArticleDOI
Hybrid modelling of homogeneous charge compression ignition (HCCI) engine dynamics - a survey
TL;DR: Model-based control synthesis requiring dynamic models of low complexity and HCCI combustion models were studied, the physical models aiming at describing the major thermodynamic and chemical interactions in the course of an engine stroke and their influence on combustion phasing.
Journal ArticleDOI
Application of a high-repetition-rate laser diagnostic system for single-cycle-resolved imaging in internal combustion engines.
Johan Hult,Mattias Richter,Jenny Nygren,Marcus Aldén,Anders Hultqvist,Magnus Christensen,Bengt Johansson +6 more
TL;DR: High-repetition-rate laser-induced fluorescence measurements of fuel and OH concentrations in internal combustion engines are demonstrated, revealing unique information on cycle-to-cycle variations in fuel transport and combustion.
Proceedings ArticleDOI
Ion Current Sensing for HCCI Combustion Feedback
Petter Strandh,Magnus Christensen,Johan Bengtsson,Rolf Johansson,Andreas Vressner,Per Tunestål,Bengt Johansson +6 more
TL;DR: In this article, an ion current signal was obtained from HCCI combustion and the signal level was very sensitive to the fuel/air equivalence ratio and the mixture quality in terms of air/fuel ratio and EGR.
