Replying to: bigmclargehuge (Jan 27, 2009 5:59 am) Na what I meant is that the type new type of diesel that they label as clean will soon be produced by GM too. I'm sorry if I wrote it in a confusing way.... Na not every car will be dirty again after a year but quite a few are (especially high mileage once). Diesel is a lot harder to clean that a gasoline engine, it's therefor easier to break. In the US where just a few % of the fleet is diesel there will no doubt be more smoking gasoline engines than diesel once. If it was the other way around there would be no point talking which one is cleaner -- it would be kind of self evident. I'm just speaking from the experience living on this side of the Atlantic where diesel make up nearly 50% of the sale. I simply don't wish the same thing happened over at your end... I'm all for green stuff, but diesel ain't one of them in the long run.. Rather see, E85, biogas etc.. Well will use the zip lock now and try to not voice it again .. I know it's negative and they probably are some die hard diesel fans here ... Cheers Dyna Replies to this message: coldcranker (Jan 27, 2009 7:54 am)

Replying to: Dynas (Jan 27, 2009 7:23 am) Well, this thread is specifically about GM's HCCI, not diesel. The fact that the thread title says "Diesel-Like" doesn't mean HCCI burns diesel. HCCI burns gasoline, in a compression-ignition mode, with higher compression ratios than regular gas engines. Higher compression ratios, if you can run an engine there, is the main way to get better fuel economy. Please check out the What would it Take for YOU to buy a diesel car discussion too. (see the link for that in a post above this) if you want to discuss diesel specifically.
