I'm pretty sure that the Jag V-12 uses a "May" combustion chamber 
designed for ultrafast (real technical term there...ultrafast) 
combustion.  It allowed the Jag engineers to go with sky-high (yet 
another technical term) compression ratios while still meeting emissions
targets.  For info on the May combustion chamber, check out Richard 
Stone's book "Introduction to the Internal Combustion Engine".  There are 
three case studies on engine design, and the Jag V-12 happens to be one 
of them.
