In the engine, fuel-rich mixtures are adopted at full-load operations to avoid knock inception and to limit the turbine inlet temperature, this resulting in high levels of brake specific fuel consumption. Since the engine is operated at the edge of knock, as documented in previous publications [3-5], it provides a useful benchmark not only to assess the influence of fuel composition on mixing and combustion, but also to improve the knock prediction methodology developed by the research group [6,7].
