All-new design to be added to our long list of engines for sale as soon as we can get our hands on them.
One of the obvious visual differences in the new 6.7-liter Power Stroke V-8 turbocharged diesel engine and the earlier 6.oL engine is the layout of the pipes. The exhaust manifolds, for example, reside in the valley of the engine instead of outboard, while the intake is outboard of the engine. The cylinder heads are essentially flipped around in comparison with previous V-8 engine architectures.
This unique layout – an automotive-industry first for a modern production diesel engine – has several advantages. First, the overall exhaust system volume is reduced, resulting in improved throttle response for the driver. The improved under-hood arrangement also places components that need to be in cooler air away from hot exhaust pipes, resulting in better thermal management and, by extension, better fuel economy.
Physically speaking, the size of the system is smaller, but more importantly, the air-handling part of the system is considerably smaller and that translates directly into the responsiveness of the engine, which is very notable, since the volume of the exhaust system feeding the turbocharger is smaller by about 50 percent because of the inboard architecture.
Combining two turbochargers in one package
The single-sequential turbocharger – is an industry first and is key to the new diesel engine’s performance. The unit is more complicated than the current turbo-systems, however little more info is available now.
The engine’s smaller exhaust volume combined with a corresponding smaller intake volume and smaller turbocharger creates a system that is quicker to boost, more responsive and better able to deliver horsepower and torque, especially at the low end, when the customer demands it.
Combustion system clean and powerful
The combustion system is the heart of the new 6.7-liter Power Stroke V-8 turbocharged diesel engine and in many ways sums up the careful balancing act the Ford designers achieved in terms of power, fuel mileage and reduced emissions. The key factor in the next round of federal emissions standards, which begin in 2010, is already covered in this new design.
Ford’s system runs the engine with the least amount of oxygen possible in order to reduce NOx without degrading performance and fuel economy. The end result is the new style EGR is returned to the intake at a lower temperature, which means more of it can be utilized, creating greater efficiency throughout the system.
The new diesel engine features instant-start glow plugs, allowing quick start even in extremely cold temperatures. Some of the newest technical advances are being used in this motor. We have to see if it can live up to the legendary Ford 7.3L diesel engines greatness. Certainly it will make Ford Diesel lovers happy, since the 6L Ford diesel was sort of a bust.

I have one of those failed 6.0L after owning 2 trucks with a 7.3L with very few issues. My concern with the new 6.7L is, I read it will have alum. heads and 2 water pumps for 2 cooling systems (the EGR cooler & block) and a Urea injection system for exhaust emissions that will need to be serviced or refilled every 7500 miles. The first concern with the heads is a diesels high compression & alum.s ability to warp with the hot & cold. The second concern is cost of regular service cost added to the normal oil changes with the need to service the Urea system. The third is the cooling systems. To complicate the engine & systems is more likely to increase break-downs & expense to maintain. The new trucks are already sticker shock & with the current economy & having to cut or hold my current rates in my own business I can’t see how anyone can upgrade or would want to.
I dont think there si going to be enny problems with the new moter. I hop it has more BALLS then the (lasy 6.0 leter)
i don’t think the alum heads wil be a problem. the duramax has used them since they begun. but the two cooling systems have me a little worried. im not sure which way to lean. is double the water pumps cause for more failure or will it be less taxing on each system? im guessing its a coin flip. time will tell. i currently have a 03 6.0 bought it new and have never had a problem with it (keeps fingures crossed).
Dont git your pantes in a bunch the new motore will grate ford did there home work trust me!
