NOx is created from heat in the combustion chamber (it comes from the side reaction of heating the nitrogen that is present in the air sucked into the engine).
There are a few ways to increase HP on a turbo.
Increase Compression Ratio (hotter)
Increase Turbo boost (can be hotter... not if it is effectively cooled)
Increase Capacity.
So... to maintain the same (or a bit more) power, they are lowering the Compression ratio, increasing the boost and the capacity.

Harder cold starts, less effecient during low boost, and horrible for extended periods of idling. Seems like with these new diesels, you have to spool the turbo(s) way up to do anything

Needs a lot of work, including some rot on the body, but shes getting there.
[The point is the 7.3 has had its share of issues too. UVC Harness corrosion, shorting out, etc..The crackling #8 injector, EBP sensors getting plugged up, early IDM problems, romping, and a lot more common issues. Most of these problems were worked out in the later years, but guess what? Same for the 6.0. The 6.0s were quite reliable power plants by 2006[/quote]
Yes i know all about the 7.3 liter problems,EBP sensors getting plugged but that was mostly caused by poor fuel quality. IMO. I am a Ford tech and have just never or heard of a 7.3 in stock form melting pistons. And most of our clients drive trucks.So i was abit sursprised to see someone saying that,thats all. As for the 6.0l being quite reliable by 2006,well the jury is still out on that IMO... I and i am not knocking the product i am a ford truck diehard fan. Just gets frustrating when you have to see the same problems day in and day out... Cheers.
Anyone else notice the current trend in diesels going the wrong way, back to large displacement engines? The 5.9 Cummins went to 6.7, 6.0 PSD went to 6.4, then is going to go to a 6.7. All in the name of emissions too. Seems like the EPA really needs to look more into these things before they make the laws.
The EPA is ruining the diesels IMO.
But I still have high hopes for the Scorpion, especially after learning that it is employing Ford/PSA JV tech.
A recent visit to the International Engine web page reveals that they no longer show a picture of a Ford truck when showing applications in "consumer vehicles" but rather a truck with a prominant "bowtie" in the grill.

GM was unable to build a decent diesel for a pickup application until recently, and so now they are going to dump that engine and buy one from a contractor that has proven to itself in providing only inferior engines. What's with that? D'oh!

Ex-neigbor in my old hood had the 7.3 engine. It melted a piston, but the engine had over 200K and some peripheral device failed (I forget what, so don't ask)...At least that was the dealerships story. He fixed it and drove it another 200K pulling his fifth wheel camper. I think his son is driving that truck now.

That's gotta be a brazillian market c**** or something, what the heck is that?
You guys do know that International bought out the GM medium duty truck line right?
1st. ?; I dunno. What does it say on the bottom of the front license plate that is obscurred by the International advertising script?
2nd. ?; Yep.

1. Isn't that just an agreement to consumate a deal? I didn't think that got past the Anti-trust folks yet. Meaning that it's in the works, buy not consumated.
2. Yup again, but that is the Brazilian light duty truck (aka Colorado), not medium duty (aka Kodiak, and others) in the picture.

One doesn't have to read Spanish or Portuguese to figure it out. . .
Thanks, that clears that up.

"Produtos > Motores Leves > Série Power Stroke"
I am curious as to this Powerstroke referance on the International website, to my knowledge no International website addressing the North American market has made a referance to "Powerstroke" since the 6.0 days.
