SUMMARY:

nternal combustion engines are still the predominant propulsion method for light vehicles, and are also present in different applications for transport, energy generation and heavy workload. According to ANFAVEA, 91% of the light vehicle registered in Brazil in the year 2019 were equipped with spark ignition engines. Given this context, development of spark ignition engines continues to be a relevant approach to transportation and energy research, aiming to improve efficiency and to reduce fuel consumption and pollutant formation. Knock is an abnormal form of combustion that imposes harsh restrictions to performance and efficiency of internal combustion engines. This phenomenon is characterized by the propagation of supersonic shockwaves that excite the engine structure and can cause severe and irreparable damage. Nonetheless, knock is a phenomenon of great importance to engines research and its identification represents a relevant opportunity to produce more efficient thermal machines. The present work aims to confront data from different methods of knock detection with data from knock computational models, including models applied in commercial software available in the market.
