Evolution of the Groundbreaking Power Stroke Diesel
From the first Power Stroke diesel engine that went into a Ford Super Duty truck in the late 1980's to the current state-of-the-art version of the 6.7L engine, the Power Stroke engineers have proven their chops. There are currently more Power Stroke engines still running in trucks than any other type of engine, and their usage in everything from construction trucks to ambulances and even snow plows shows the scope of their performance and dependability.
Evolution of the Power Stroke Engine
1982 - 1993: A relentless drive to improve the durability, power and torque capabilities led to a partnership between Ford and ITEC (International Truck and Engine Corporation) to create the diesel technology that helped redefine the industry. This partnership resulted in the first 6.9L IDI (Indirect Injection) engine, with a modest 170 HP and only 315 lb-ft of torque.
1994 - 2003: From IDI to DI - Direct Injection changed the playing field, allowing the 7.3L powerplant with added turbocharger to become one of the top ten diesel engines ever produced.
2003 - 2007: With an emphasis on reduced emissions, the 6.0L Power Stroke diesel engine delivered a next-gen fuel injection system that resulted in a major increase in horsepower to 325 HP and boosted torque to 570 lb-ft.
2007 - 2010: Diesel emission requirements continued to tighten, and Power Stroke engineers responded by offering a 6.4L version that pumped out 350 HP, with 650 lb-ft of torque at a 2000 RPM. Extensive testing of the twin turbochargers gave this engine a technological leap forward.
2011: The lightest, most powerful and fuel-efficient of the Power Stroke engines, the 2011 6.7L still steals the show with B20 fuel compatibility, "Instant Start" glow plugs and a lightweight graphite iron engine block.
Engine and Transmission Sizes
While engine sizes have changed over the years and are dependent on the supporting transmission, Ford has now confirmed that a new Power Stroke diesel engine in a 3.0L size is in the making for their 2018 F-150 1/2 ton truck. The engine is expected to work seamlessly with the rumored 10-speed automatic transmission and tow up to 7,000 pounds when properly equipped.
How Power Stroke Engines are Different
Power Stroke diesel engines have been refined over the years, and now boast precise injection timing and additional innovations such as piezoelectric fuel injectors -- all of which support the engine's quiet, smooth cycles. Continuous advancements provide this powerhouse of the trucking industry to improve power, torque, towing and hauling capacity all while reducing emissions and enhancing gas mileage.
