Excerpt

Over the past 15 years, Shell has published the results of various studies which show that for modern downsized gasoline engines, a high research octane number (RON) increases engine efficiency in the regions of the operating range where combustion is limited by engine knock. However for a given level of RON there is no advantage to having a fuel with a high motor octane number (MON), and there can even be a disadvantage. This can be explained from an analysis of the chemical kinetics of gasoline autoignition in the specific temperature and pressure regimes of a modern downsized boosted engine. In the following Shell summarises findings from three recent collaborative projects which support this emerging understanding. …
