I read about it before (I think Car and Driver)...it's a pretty cool technology, and I hope it works for the long term.

Looks like they're making very rapid progress with HCCI. They weren't even talking about this a 18 months ago.
I bet with its narrow band of operation, it's well suited to powering, oh, say, a range-extender engine on, oh, maybe, plug-in hybrid? D'ya think? |

What a great find. Most excellent.
Did anyone else catch the "using less than half the gasoline" comment? Whoah. I can see it now..... Quote:

Re: HCCI: GM making advances with its "newest" fuel-economy improving engine tech
i can see this in application by the end of the next year. 35mpg average here we come.
now i'm somewhat confured though, i know hcci comusts gasoline by compression, but is gm working on a system where they inject water into the cylinder every fourth cycle to reduce the gas usage further or is that a different system that i'm thinking of?

Interesting. Wonder if it'll add to the cost of the car at all?

Great!
Let's get this science project in commercials and in the showroom! Things like this cold help make Saturn a real volume-seller. "re-think?" |

Every flimsy switch, every panel of sheetmetal not changed from platform mate, and every technology featured not put into the DIC, instrument cluster, or radio, has paid for this R&D science project. I hope it gets deployed. |
