Jet ignition is a technology used in stationary or
marine natural gas internal combustion engines application
[4, 5] with pre-chamber injection of part of
the fuel and ignition spark initiated or self-glow-plug
assisted. Jet ignition pre-chambers have also been
proposed for transport engines with in-cylinder homogeneous
mixtures [6] or bulk, lean stratified [7, 8]
produced by direct injection.
