A new era in Ford diesel technology arrives with the unveiling of the company’s latest 6.7-liter Power Stroke V-8 turbocharged diesel engine. Set to debut in the 2011 F-Series Super Duty pickup truck, the new diesel engine is expected to deliver significant improvements in torque, horsepower and fuel economy while adding more fueling flexibility and helping Ford meet stringent new emissions requirements.

So far Ford isn't releasing much in the way of numbers for either power or efficiency of the new engine other than to say that it is both more powerful and more efficient than the engine it replaces. What we do know is that the engine features several automotive-industry first for a modern production diesel engine.

These include an ‘inboard exhaust’ architecture and a unique ‘single-sequential’ turbocharger with a double-sided compressor wheel mounted on a single shaft.

This turbocharger design allows the single unit to deliver the benefits of a twin-turbocharger system in a smaller, more efficient package, combining the benefits of a small turbocharger (faster response) and a large turbocharger (ability to compress and force more air into the engine for more power) in one unit.

The engine also gets a high-pressure Bosch fuel system that injects diesel at up to 30,000 psi and aluminium cylinder heads for reduced weight.

One of the obvious visual differences in the new 6.7-liter Power Stroke V-8 turbocharged diesel 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. Advantages include a smaller exhaust system and improved cooling.
