Diesel efficiency out of a gas engine

Dismissed as a laboratory curiosity in the 1970s, homogeneous charge-compression ignition (HCCI) has now emerged as a more feasible alternative to alternative fuels—and it’s almost ready to roll out en masse. When used in conjunction with other advanced engine technologies, this combustion process can help deliver a whopping 25- to 30 -percent better fuel economy than today’s spark- or compression-ignited internal combustion engines (ICE). HCCI does all this with near-zero emissions, just like a hybrid—and it won’t have any impact on your driving habits or come at a premium price.

General Motors is to a large extent leading the big new charge to re-engineer the engine, and they recently offered Popular Mechanics an exclusive tour in the depths of their Research and Development Center in Warren, Mich. That’s where HCCI’s Paul Najt runs the Powertrain Systems Research Lab—and has some serious gear for making this revolutionary compression technology, well, try to save the world.

It says that GM is leading the way, I hope that this is one of those things that GM and Chrysler are sharing the costs/benefits on.  Being able to drive a Ram with a Hemi that displaces a good 5.x liters and gets 25ish mpg without the help of a hybrid system or other complicated crap that can break.

This is great.  We need more mpgs out of gas engines.

[flint]

Do we also get the same torque numbers??  If we could get the huge torque down low gassers could replace diesels as the ultimate rock crawling engine.

[diesel game]

Does this mean we can make diesel engines even more efficient?  That would be nice so I can keep being smug

I don't think so.  Diesel already runs cooler and this seems to use a combination of high compression and spark.  Your smug might have to go away.

This is interesting.  I was looking to move up to a V8 ctd in 2012 or 2013 but if chrysler has a hemi out by then that's just as efficient I might have to give that a try instead unless diesel prices are back down again by then.

I bet chrysler is in on that.  All this R&D costs a lot of money and no one wants to foot the entire bill these days since it could turn out to flop.

I find very little chance of a vehicle that gets close to 100 mpg being a flop.  As long as it doesn't look like a prius everyone will jump at the chance to own something that gets such good mpg.

Our smug will last forever.  It might just have to come from somewhere else.  Like, did you know that diesel engines can run on peanut oil?

You can have your smug back as soon as you show me the first reciept from a peanut oil station

[diesel game]

hey now, we can just show you a receipt from the grocery store buying vegetable oil.  The stuff is probably cheaper than diesel is per gallon right now anyways.

vroom vroom the V8 will live on.  Hopefully there'll be enough alternative fuels to drive our cars on that gas engines can stay in the mix a while longer.

I doubt we'll ever see gas engines go away fully.  They might become a novelty or something like that but they'll be around.

[diesel game]

They'll be around like like we have steam engines around.  They'll sit in a museum somewhere as a part of history, but no one will use them.

This is sweet.  Right now it seems like gas is cheaper to make than diesel so if we can get better fuel economy out of the gas engines then we're on our way.
