Looking at this:
and
I couldn't help wondering what is would take to have a separate, very small, injection system for the pre chambers?
This is superior to getting a richer mixture into the chamber via intricate in (main) chamber aerodynamics is it not pgfpro?
But it also occurs to me that the chamber has to be exhausted of burnt gasses so there's air for the fuel, so perhaps not?
Yes to have a active pre-chamber would be awesome but still haven't figured it out yet?
The whole (richer mixture) filling and scavenging of the pre chamber is still 'doing my head in!'

Gasoline Compression Ignition GCI seems easier!??
lol yeah it is very complex on making a passive pre chamber feed the fuel lol
This makes more sense to me:
Honda always has the cool things
