Ford codenamed the latest 6.7L Power Stroke engine the "Scorpion" due to the turbo placement on top of the engine. The Scorpion features many groundbreaking changes in 2011, such as a compacted graphite iron (CGI) block for greater strength and reduced weight, reverse flow aluminum cylinder heads with exhaust ports located in the lifter valley, dual water jackets, six head bolts per cylinder, and a 29,000 psi high-pressure Bosch Common Rail fuel system, which is a first for any Power Stroke engine. The system delivers up to five injection events per cylinder per cycle using eight-hole piezo injectors. This 6.7L Scorpion also supports B20 biodiesel. Honeywells unique single-sequential turbocharger features a double-sided compressor wheel mounted on a single shaft. It combines the benefits of a small turbocharger for quicker response and a large turbocharger with the ability to compress and force more air into the engine for more power all in one unit. Emission controls include exhaust gas recirculation (EGR), Denoxtronic based Selective Catalytic Reduction (SCR) from Bosch, and a Diesel Particulate Filter (DPF). The new engine control software bumped the horsepower to 400 hp @ 2800 rpm and 800 lbft @ 1600 rpm.
