Ford to release new 4.8L Dual Injection V8 for F-150?


Recommended Posts

Seems to slipped under the radar here:



A portion of the C$600 million will be used to update existing 5.0-liter V8 engine production at the Essex Engine plant, according to the two sources, who declined to be identified because the plan is not yet public. The updated engine is expected to be a 4.8-liter V8 for the F-150 pickup truck.

 

And here:

Ford Authority reports that this 4.8-liter V8 will have both direct- and port-fuel injection, a system first used by Toyota on its 3.5-liter V6. By utilizing these two types of fuel injection, Ford can run a higher compression ratio, boosting fuel efficiency and horsepower without resorting to turbo- or supercharging.

I just find it odd that they would drop a V8 down in size, add 8 more injectors, and keep it a NA engine. To me, that doesn't add up. Too much expense and complexity added for what?

There are still V8 truck buyers. This will make the V8 offering even more competitive.

 

Imagine a 4.8 that can spank the 6.4 and 6.2 offerings from Ram and GM

It won't be the first time Ford called a Mustang "5.0" without 5 liters V8 under the hood. The original "5.0" was a 4.9 :)

 

 

Well from the article, that isn't happening. The only the F-150 getting it is interesting...but outside of forced induction, will a 4.8L really have that much going for it over the current 5l?

Yes, emissions requirements are about to get far more stringent. Currently direct injection causes carbon build up and a dirtier burn. Using both injection types will allow them to meet power, economy, and emissions requirements.

DI does not cause carbon build up, that came from stem seal leakage on early Euro and Jap DI engines.

The real issue with DI is particulate formation on start up when the fuel strikes cold cylinder walls,

that's where starting on PFI has a distinct advantage..

 

The real reason for using both DI and PFI is that the result is smaller injectors with closer control on

fuel metering for added efficiency and emissions calibration.

GM and FCA both use cylinder deactivation on their V-8s correct? Ford does not have any V-8 with this feature? A friend has a GMC and claims some pretty impressive MPG numbers with this 4 x 4 1/2 ton.

I took a 2015 GMC/ 5.3L loaner truck to Sioux Falls to get a transfer case once. Got 14mpg. Is that impressive?

 

Same stretch of road I've got 21-23 with my 2.7EB.

My buddy with a 2015 Silverado claims some impressive MPG's also.

How fast were you rolling?

Ford had announced their version of cylinder deactivation on the 1.0 EB. It was a much less complicated system that what Chevy does and achieves pretty close to what they do. Mechanically they just had to change the balance a bit. I wonder if a lot of that had to do with the fact it's a 3 cylinder.

 

My point it, I'm betting that rolling fuel inject cut off will make it into future generations of EB and NA engines. It's only about 5% gain. But that will add up for CAFE ratings.

Exactly! this friend of mine with the GMC made it a point on a northern Maine to central Mass trip tom set the cruise to 65 on I-95. Got 25 mpg. NO LOAD in truck. The guy is a bit of a GM cheerleader but does swear by the economy and power of the truck.

A poster on another forum is hinting that the new engine is actually a reworked 5.0 Coyote but with

an ever so slightly larger bore but still just under the 5.0 liter mark.

 

If true, I wonder if that signals a lot more changes to the engine that adds up to more torque and horsepower.

I keep thinking about that Ford Performance crate engine with the GT350's type heads and similar cam timing,

that engine puts out 541 hp and 408 lb ft - so ford could easily dial that back to 480-500 HP production 5.0 V8...

 

Just a thought...

Why do they need to?

 

 

Not too many going to trade up their 5.0 for less motor (I won't), even if it has more "stock" HP

on papaer. Now if they made a "mild" 4.6 V-8 eco, I'd be all over that. 450 HP/ 520 torque stock

would be simple.

 

Then a simple tune puts you @ 500/600. The aftermarket might be pissed since

few need much above that.
