Knocking combustion in spark-ignition engines
Zhi Wang,Hui Liu,Rolf D. Reitz +2 more
TL;DR: In this paper, the authors provided deep insights into the processes occurring during knocking combustion in spark ignition engines, and future research directions, such as turbulence-shock-reaction interaction theory, detonation suppression and utilization, and super-knock solutions, are also discussed, including use of exhaust gas recirculation (EGR), injection strategy, and the integration of a high tumble - high EGR-Atkinson/Miller cycle.
