Direct Injection - Stratified

[Dave Williams]

-> Any time a device that restricts flow is introduced into the path of
-> air and fuel, power is reduced.  A pre-chamber is such a device and
-> such an engine will lose efficiency compared to an open chamber
-> design.

 A prechamber doesn't necessarily have to restrict flow.  It can be *in
addition* to normal flow, as was used in various Japanese automobile
engines a few years ago.
