It's been a given that when we can boost compression, we can get more efficiency out of a gallon of gas. Because of the fuels we use like 87 to 93 octane rated fuels, we are limited on just how much compression we can run before the engine beats itself apart with predetonation. Suppose you were offered an engine package that were capable of more power but uses 2 fuels, both readily available. Would you be interested? Would a fuel mileage increase of 20-25% be of interest with out loss of power? If the engineers at Ford have their way, you might be seeing these engines in future cars. The fuel- regular gasoline and E85. The E85 has a much higher resistance to ignition or higher octane rating and it also provides a cooling effect to combustion temps. Both characteristics provide for more power and fuel mileage in engines designed with higher than normal compression ratios of around 12:1 or more. It also makes for a cleaner exhaust and cleaner combustion. Does any of this sound good to you?

 

Um, yes? Too bad for me because I don't think I'll be selling or trading my truck for the next 20 years.

 

Haha, sorry... your post instantly made me think of this:

you can already run bio diesel through older diesel setups, but stock diesels arent setup to start or stop on bio.

whats your point labnerd? Is this all hypothetical?

 

This technology has nothing to do with diesel. It is an ethanol technology that allows more efficiency of the gasoline we are getting from other countries. It will allow us to get a little farther away from the folks that would like to see our demise. The engines are up and running the streets already. The importance is that you can have a much smaller displacement engine making the same or more power than what you are driving now. Town MPGs will be going up for those with stop and go traffic yet need the power of our current V8 engines. If these hit the streets, it will probably go to municipal users first for real world testing as to the user having to deal with 2 fuels. While the mix of ethanol and gasoline is important in these engines, the usage of the ethanol is less than you would imagine- about 5%. That's pretty much all it takes for these to work but it is an on demand type fuel system. Kinda like displacement on demand.

 

interesting.....

is that what ecoboost is all about or is it something different?

 

I like my medium sized v8.

 

Something very different although some of the technology is from the EcoBoost project. This engine has 2 injectors per cylinder and employs 2 turbo systems on engine blocks somewhere around 3.0-3.5 displacement. These engines are also extremely clean burning and will have lower emissions. EcoBoost is on the streets already in the Lincoln but considering current auto sales, there won't be one at every traffic light. Jeez, around here, this is truck country as they like to call it and I've seen very few new F-150's.

 

Labnerd, your about the only one I would take serious on a topic like this. Yes, this is something I would be interested in. It does make sense, more octane, more compression, more power.

 

Elaborate for us here.....Is this something that Ford will seriously be offering in the future? Do we need to do something as a country to push forward the need for this and increase our chances of getting it? I realize that everytime we come close to higher technology, oil prices drop and we go back to our old ways. I'm only 31 and I know it's happened more than once. I would love to see an increase in power and cleanliness along with a drop in fuel consumption and displacement. I love big V8's but I am not so nieve as to believe that they are the only solution to our desires. Tell us more.......

 

I wonder, since it's going to have a shorter stroke, will it develop its torque at a higher rpm? It may sound like a bumble bee
Very interesting find.

 

Hate to rain on anybodies parade but it takes about 1.5 gallons of ethanol to produce same energy output of petrol(gas).Therefore mileage is going to be worse whatever you do,the heat value of ehtanol is much lower,and cost because of this will be about 23% more.
But it does run cleaner !!!!!!

 

Me too! it's hard to beat the 5.4's combination of Power/torque & fuel economy.......

 

I think maybe it is an efficiency issue. Because we only recover a percentage of the energy used in an engine now. With the improvements of the higher compression, and the two injectors. It may be com busting closer to TDC, using the energy more efficiently. So in effect recovering more of it.
Of course that would include higher fuel pressure injected more quickly, at a lower volume.

 

Coming from the 'Stang side of it: Lots of comparisons done converting 03/04 Cobra's over to E85. Sure, they made more power, burn cleaner and cooler, but used more fuel. I'm cornfused by original posters topic, but agree w/the one I quoted.

What concerns me is Obama's minimum/mandatory MPG legislation he signed off on. I actually think we're going start losing cubic inches AND HP.
