Cyclically resolved flame and flow imaging in an alcohol fuelled SI engine (2018)
Journal Article
Moslemin Koupaie, M., Cairns, A., Xia, J., Vafamehr, H., & Lanzanova, T. (2019). Cyclically resolved flame and flow imaging in an alcohol fuelled SI engine. Fuel, 237, 874-887. https://doi.org/10.1016/j.fuel.2018.10.075

The work was concerned with improving understanding of the interaction of the bulk in-cylinder flow with turbulent premixed flame propagation when using varied fuels including iso-octane, ethanol or butanol. The experiments were performed in a single... Read More about Cyclically resolved flame and flow imaging in an alcohol fuelled SI engine.

Study on pollutants formation under knocking combustion conditions using an optical single cylinder SI research engine (2018)
Journal Article
