Does Ford Patent Confirm 'Scorpion' Diesel Design?
A patent application filed by Ford for a "Push Rod Engine With Inboard Exhaust" has been published by the U.S. Patent and Trademark Office. The legal eagles at the law firm Stamoulis & Weinblatt LLC found the publication during a recent intellectual capital search. Its contents likely cover the upcoming in-house-designed 6.7-liter V-8 diesel engine, code-named "Scorpion." The all-new engine is expected to replace the Navistar-sourced 6.4-liter V-8 Power Stroke diesel engine in Ford's heavy-duty pickups by 2011. Our spies recently caught the Scorpion while it was undergoing testing in public.
According to our sources — as we first reported in July 2008 — the Scorpion is said to share several key traits with GM's indefinitely postponed 4.5-liter Duramax V-8 diesel engine. Intake and exhaust flow through the cylinder heads is reversed relative to conventional diesel engine design, with the exhaust exiting directly into dual sequential turbos sitting in the engine's valley. Unlike the Duramax, the Scorpion diesel is said to use an overhead valve (pushrod) engine design rather than overhead cam.
The patent application describes a four-valve gas or diesel engine with that same architecture, and it includes a diagram that shows one or more turbochargers mounted between V-style cylinder banks.
The innovative reverse-flow design is said to provide several operating advantages and efficiencies over a standard diesel engine. The arrangement shortens the distance between the exhaust and turbos, improving turbo response while protecting peripheral powertrain components, like the fuel pump and alternator, from excess heat. Higher turbo outlet temperatures also provide extra heat to downstream emissions devices to improve pollution-scrubbing performance sooner when emission catalysts (used to break down harmful pollutants) are warming up.
Does this patent describe the Scorpion diesel? Our sources say it does. There's no official word from Ford yet.

This is great, but i would like to see Ford start offering 4 and 6 cylinder diesels for some of its non-commercial US products. I think if a turbo-4 or NA 6 cylinder is offered with the upcoming explorer they will sell like hotcakes. I think the focus should be more on diesels rather than hybrids. They could have placed a diesel 4 in the new Fusion and gotten the same results or better than the hybrid package.
Inboard exhaust must be the new design trend.
BMW already has it on their production turbo V8 engines.
From a packaging stand point, it makes sense.
Whatever kid of diesel they make its gonna be junk! Just like everything they make is junk. I mean come on ford pack it in already, you have been junk for long enough just go for bankruptcy. HA HA HA GO TOYOTA
ford builds the best trucks always has always will. there are some things they could do better but overall still the best. as for toyota, nothin but a wanna be truck. its a great grocery getter and thats about it.
POWERSTOKES ARE BY FAR THE BEST TRUCKS ON THE RODE,STILL THEY COULD BE EVEN BETTER WITH A TRUE INLINE 5 MOTOR, 23 MPG IS HARD TO BEAT AND I GET THAT IN MY 1 TON 93 DODGE. JUST IS NOT THE TRUCK MY 04 6.0 LARIAT IS THOUGH. GOT RID OF THE EGR, STRAIT PIPED 4" FROM TURBO TO BACK,SOUND BRUTAL AND AT 112,000 MILES HAVE NOT HAD 1 PROBLEM.
I have to agree. I have an 07 lariat. straight piped it with 5'' from turbo back. it outruns my buddies chevy, and with a chip will do a burnout all day long!
why the hell is dodge the only one auto make who is allowed to have a giant in line 6 cylinder diesel engine i love dodge dont get me wrong but i am a ford guy from birth and ford made there own 6 some yrs back and now its like they dont even know what the hell you are talking about when you ask them about the 6.6 0r the 7.8 they were making in the 90,s its a shame that no matter what if you are ford in a card game the only card you are allowed top draw is under the jack why cant ford be on top like yrs ago its stupid
