Will be interesting who makes it to the diesel 1/2ton market first...

(and more importantly, who gains the most sales out of it)

 

I enjoy the different approach to engineering this engine in regards to the design of the heads, and the exhaust. It makes sense to build a turbocharged V engine in this manner. After all with current V8 turbo diesels the turbocharger (giant heat sink) is still in between the cylinder heads basically on top of the intake runners, where it can heat up the charge air that just had to get cooled off in the intercooler.

 

I wonder if it's possible to not refill the urea thing and not set off a million idiot lights. That's just one more thing that I'm not going to want to fill up for $3/gallon.

It would be good for Ford to be the first but they cant afford rushing it out and stuff not being right with it.

 

I thought that was a good idea too.

The industrial turbo'd V12 Cummin's at work all have the same set up, just makes... sense.

 

Supposedly the urea only needs to be refilled on about the same basis as an oil change. The chemical itself is not all that different from common amonia, so it shouldn't be terribly expensive.

 

We use diesel engines (V16, V12) in locomotives with the same set up for exhaust in the center of the V. Also helps heat escape from the fans on top of the locomotive hood, instead of the sides which are shuttered.

 

urea is one of the main components of **** ain't it?

 

yep.



... and rednecks rejoice.....

 

I agree, everything is better with the intake exhaust location, but remember, the engineering goal was to make it fit in the same area that a small block fits. Therefore, where would you put a turbo besides in the V of the block?? Remember, the left and right banks both now have air intakes which would create a heat inbalance in Left vs Right. So that would be worse than equal heat in both sides of the motor....would it not?

 

I don't understand what you are trying to suggest...

 

Schya, as if. Ford wouldn't do that. They've got enough experience with that and as we all know, history never repeats itself.

 

There should not be any heat imbalance from left to right on the engine, unless the cooling system is just horrible. There could be unequal air flow to one side or the other, but that is even very rare these days.

 

That is my thought on the charger anyway...the center keeps heat, airflow and turbulance the same for both sides. Besides, what happens when you put a bigger turbocharger on it than the stock one. You don't want to have to worry about porting a head different just so it flows right.

Heat imbalance would stem from different airflow, I am talking left to right EGTs, not Coolant temps. JMO.
