considering that it would be working with direct injection (like that of the V6 camaro), preignition wouldnt be that big of an issue as you wouldnt be injecting the fuel until right up until the point of ignition anyway. that added in with the exhaust gas that stays in the cylinder with this design would minimize the chance of preignition. to an extent, its the same way the V6 currently operates only without a spark plug to ignite the combustion mixture.

Okay, not really.  Last I read about it, the biggest issues they needed to overcome for production was NVH, top-end performance (above speeds of 55mph required the spark again to work), and calibration. This technology takes the complexity of DI to a WHOLE new level.
Seems pretty cool on the surface. I look forward to watching how it develops. 
Great video, btw, Spike! |
HCCI technology is old so to speak, but you dont see it in operation today (outside of diesels).
to further the discussion on "future" technologies... how bout GM's BAS system?

another "old" technology, that is just barely starting to make its way into the mainstream automotive design.
