Abstract: Abstract Spark ignition induced super-knock was generated in a rapid compression machine using stoichiometric iso-octane/O2/N2 mixture. In addition to the pressure traces, the combustion processes were also recorded using high-speed photography, from which the characteristics… read more here.

Abstract: Abstract In this work, three different combustion modes were obviously observed under different oxygen concentrations, including normal combustion without end-gas autoignition, end-gas autoignition without detonation, and end-gas autoignition with developing detonation for gasoline. The results… read more here.
