Ford applies for patent on turbocharged pushrod V8

The staff at intellectual property law firms spend much of their time scouring the database at the US Patent Office for applications that might impact their clients. At Delaware-based Stamoulis & Weinblatt, they have discovered a recently-filed application from Ford for a new V8 engine. Interestingly, the patent describes a pushrod, 4-valve per cylinder unit with inboard exhaust and outboard intakes as well as turbocharging. This isn't the first such manifolding setup; we've seen it recently with BMW's 4.4-liter turbo V8 and the just-canceled GM 4.5-liter diesel, both of which followed this model, only with overhead cams. The law firm's blog speculates this engine could appear in the Mustang in 2010, but this will almost certainly not be the case.

Careful reading of the patent application shows that it focuses on the intake/exhaust layout and valvetrain configuration. The text indicates that the technology could be applied to either gasoline or diesel engines. What we're probably looking at here is the layout of Ford's new Scorpion diesel V-8, which will replace the Navistar engines used in its Super-Duty trucks. Ford is unlikely to put such an engine in its cars anytime soon, instead focusing on smaller EcoBoost four and six-cylinder engines.
 
0.o Good lord Ford is orgasming over their new found friend, Boost... LOL good to see though
 
sorry, their new found enthusiasm for Turbo motors...hell their press release last year said by the 2013 model year, 90% of all cars sold will have ecoboost

why be sorry? I was thinking BMW has found enthusiasm for turbo motors as well.
 
i understand that mikey, but why S/C? Benz tried the whole supercharging thing and they gave up, and the rest of the industry is going turbo...Maybe they're being niche, but still, more potential in turbos
 
UPDATE: More news on Ford's forthcoming ethanol injected, turbocharged "Bobcat" V8



Pickuptrucks.com has been doing some digging in the U.S. Department of Energy's document treasure trove and uncovered some information on Ford's new Bobcat (no, not the Mercury). It turns out "Bobcat" is the code name for a new boosted and ethanol-powered engine being developed in Dearborn.

The Bobcat engine is a new 5.0-liter V8 with gasoline port injection and turbocharging. A second set of direct injectors is used to feed a small amount of ethanol directly to the cylinders. The ethanol is used primarily for charge cooling, allowing the engine to run at higher boost and compression levels. It also allows the engine to run much leaner. Normally, running lean causes higher combustion temperatures, thus increasing production of NOx. However, the ethanol helps to alleviate the NOx by reducing combustion temperatures, and according to the data, Ford has been able to increase the brake mean effective pressure (BMEP) of a prototype E85 DI V6 engine from the standard 17 BAR to about 27 BAR.

BMEP is a measure of specific output of an engine independent of displacement. That BMEP of 27 BAR in a 3.5-liter V6 translates to a torque output of 553 lb-ft. Compare this to 350 lb-ft from a standard 3.5-liter Ecoboost and you know good things are on the way. Specifically, the 5.0-liter Bobcat can produce over 500 hp and 750 lb-ft of torque. That's the kind of torque number typically associated with big diesel engines and handily beats the 650 lb-ft of the 6.4-liter diesel currently offered in the Super Duty pickups.

The beauty of this particular ethanol boosting is that it can potentially offer better-than-diesel performance and efficiency without the expensive particulate filter and urea injection systems. If the concept can be scaled down effectively to smaller displacement engines, it could be the next step beyond the Ecoboost engines coming over the next couple of years.
 
Question: ...how is ethanol put into the car or truck in this case, and how often is it being replenished?
 
I don't know, but 750 Ib-ft of torque in anything sounds good to me.
Put that sucker in a new lighting and we got some fun.
