Effect of flame speed on knocking characteristics for SI engine under critical knocking conditions
, 2020Engine knock essentially involves the interplay between end-gas auto-ignition and primary flame propagation. However, literature shows inconsistent correlations between turbulent flame speed and knocking intensity.
