yep the passive pre chamber design but now to find some to suit jp engines!
Pre chamber tech prob goes back to ww2 and maybe further back.
The thing is F1 has been using it for quite some time running 17:1 and
for quite some time obviously pre chamber style plugs have been kept
away from mass produced cars or the gains from current super thin nasty
piston rings, direct injection and other complex technologies would be
poor selling points when an A series 30 years ago could get the same
economy as a hybrid today yet with swirly port heads.
Today the same A series with passive pre chamber plugs, piston and
engine heat and friction coatings would ruin many newer engine figures.
If an LS can pass emissions then the venerable A series would easily
too if developed further.
TBH for at least 20 years I wondered why manufactures didnt use
pre chamber designs on their gasoline heads like Mercedes Benz
has now on their new engine which supposedly is 50% efficient
followed by Toyota`s 41% which are both great efforts however
if you saw the Benz tech its so complicated its scary when
just some sparkplugs could do the same.
