This research involves identifying the fuel properties and engine parameters that mitigate knock and emissions, while maximizing boosted SI efficiency and performance. compression ratio, extent of downsizing, etc.). Of the fuel properties investigated, these six were found to have the most impact on engine efficiency and emissions.
