Third-generation Power Stroke engines use a new fuel injection system with new injectors that reduce noise and improve combustion, offering up to 8 injection events per stroke and a more precise fuel spray.Īnother good update came with 2020’s Power Stroke, improving on previous versions and making it even more reliable. The lightweight body and weight-saving engine design also result in excellent fuel economy. Previously, these numbers had only been attainable with diesel tuning and other diesel performance modifications. The 2021 Ford Pickup trucks with the 6.7 L Power Stroke reached an output of 475 hp at 2,600 rpm and 1,050 lb-feet at 1,600 rpm, making it the best-in-class diesel in horsepower. This update brought the engine to 400 hp at 2,800 rpm and 800 lb-foot at 1,600 rpm, while providing better fuel economy. Originally, output was 390 hp and 735 lb-foot, but Ford announced an update to the engine soon after production started. Emissions controls include a diesel particulate filter (DPF), Denoxtronic-based selective catalytic reduction (SCR) from Bosch, and exhaust gas recirculation. The engine supports B20 biodiesel, meaning it can accept 20% biodiesel and 80% petroleum diesel. New steel pistons are used for higher firing pressure and lower friction. The cylinder head, engine blocks, bearings, and connecting rods provide greater reliability, and the ability to handle extra output and greater cylinder pressures. The engine has received structural enhancements over the years. Up to five injection events per cycle were delivered using eight-hole piezo injectors that sprayed fuel into the piston bowl.Ģ022 Ford F450 6.7L Powerstroke Platinum w/ FX4 Off-Road Package The engine featured a block made from compacted graphite iron, giving it greater strength at a reduced weight, as well as reverse flow aluminum cylinder heads with dual water jackets, six head bolts per cylinder, and a 29,000 psi high-pressure common rail Bosch system. It provides both durability and performance while still being significantly quieter than previous Ford diesel engines.ĭue to the exhaust manifold and turbocharger being mounted in the engine’s valley, it was code-named “Scorpion” during its development. The engine is a diesel, 90-degree 8-cylinder engine, featuring an Overhead Valve (OHV) design. It has remained a staple of Ford Super Duty trucks for more than a decade, though it has gone through a number of changes. What makes this engine so great, and why do so many love it? Engine Overviewĭebuting in 2011, Super Duty trucks (F-250 through F-550), the 6.7 L replaced the problematic 6.4 L Power Stroke and was the first Power Stroke developed and manufactured by Ford, designed in conjunction with AVL of Austria. One of the most powerful and capable engines being manufactured, it can provide tremendous performance and towing capabilities. Today’s powertrain of choice in Ford Superduty trucks and cab chassis trucks is the 6.7 L V-8 Power Stroke engine. 2022 Ford F450 6.7L Powerstroke Platinum w/ FX4 Off-Road Package Ford's 6.7L Power Stroke: The Powertrain of ChoiceĪ In-depth Look at the Ford 6.7L Power Stroke
