Zusammenfassung
The ongoing trend of enforcing lower fuel consumption and tightening emission standards, combined with ever-increasing customer demands and severe competition on the global market is the main driving force for further improvement of the internal combustion engine regarding its efficiency and emissions. The most significant operation limit of spark ignition (SI) engines still prohibiting the accomplishment of these goals is the occurrence of knock, although this phenomenon has been observed for the first time almost 100 years ago. High compression ratios, which are desired for further improving efficiency, result in increased cylinder pressures and temperatures that, in turn, promote the occurrence of knock.
