Ethanol-injected Ford Bobcat V8 detailed in DOE documents
December 31st, 1969
Ford’s new EcoBoost range of engines is about to go on sale, debuting in the new Lincoln MKS before filtering across to most of the automaker’s lineup. EcoBoost promises to deliver more power but better fuel economy. For example, a 3.5L EcoBoost V6 is estimated to produce up to 340hp (253kW) and 340lb-ft (460Nm) – levels that were once the realm of much larger displacement V8 engines.
The key to its efficiency is the application of two proven fuel-saving technologies: turbocharging and direct-injection. However, a second-generation EcoBoost engine could improve fuel economy a further 5-10% by applying an additional ethanol-injection system.
We first heard about Ford developing a new ethanol-injected V8 engine codenamed ‘Bobcat’ late last year. The development of the engine has now been confirmed with new documents filed with the U.S. Department of Energy (DOE) and published on PickupTrucks.com.
The system works by injecting a blast of ethanol directly into the cylinder chamber before combustion along with a blast of petrol. The burning of ethanol has the positive side effect of cooling the combustion chambers, and when combined with the higher octane rating of the organic-derived fuel power and efficiency can be boosted.
This characteristic also allows the engines to run at a higher compression as detonation is also reduced. The end result is diesel-like economy from a petrol engine. Such a set-up would require a second ethanol-only tank to be installed in the car but so little is used that filling this tank would only need to be done once every few months on average.
Ford is working on the new system with Massachusetts-based firm Ethanol Boosting Systems, which has trademarked the term ‘Direct Injection Octane Boost’ to describe the process. According to the documents, the direct injection of ethanol effectively increases the octane of regular petrol from 88-91 octane to more than 150 octane. Using such technology, a 5.0L V8 Bobcat engine could potentially produce 500hp (373kW) and 750lb-ft (1,015Nm) or more of torque.
No word yet on any release date but Ford is expected to start the first real-world tests of the system in an F-series pickup truck by the end of the year.Ford EcoBoost technology

Yeah, the engines are under the Bobcat name from what I read on pickuptrucks.com and AutoBlog

Long as the EcoBoost option is reasonable, personally I want more diesel, but this looks good.

EcoBoost is starting to sound like an overtake button on the indycars or CART championship racing. If you need it just press the button, LOL.
I love it. But it sounds bad when you have to fill up two things at once.
If you only have to fill it once every 6 months would be nice, just like changing your oil.

Well bambam, if you drive a diesel larger then the 2 liter VW, you need to refill the urea tank, not much different in this.
This is also promising and exciting, as well - I hope this comes to fruition in the truck line and perhaps a high-end Mustang offering. The EcoBoost V6 in the D3 line-up opens up some eyes as it is, and you have a Coyote V8 on-deck for the truck range and Mustangs, plus a Boss V8 for the Super-Duty and some F-Series trucks, too.
I would love that V8, great milage and all that torque....must resist drooling
im just going to suggest for a moment that that "effective octane rating of 150" is wrong. ethanol has an octane rating of about 115, and as we all know, low grade petrol has an octane rating of 87. combining the two will not result in 150. impossible.
unless the effective octane rating of the reaction hits 150 because the 115 octane rated ethanol is pumped in JUST before combustion.. but again.. i cant see it happening.
2 plus 2 isnt 7, and it never will be.
750 Lb-ft?!!!!!! This would make for an explosive GT500! Or better yet, something less chunky like a new Ford GT. A man can dream, right?
This would be good in the Raptor
ok, so I need to find Ethanol for the one tank and use regular in the other. Where do I get Ethanol? And Im sure its not cheap. What about direct fuel injection without the Ethanol? Chevy is pumping out over 300hp from there v6. Im not saying that its the best by any stretch (chevy v6), but it just seems like a hoakie add on wanna be green power booster. Ford engineers need to look much further down the road to a solid replacement power source not the economy/power adder band-aid that might get implimented in NASCAR.
