On Tuesday, September 24th, 2013, Ford reached a noteworthy milestone by installing the 500,000th 6.7 liter Power Stroke V8 turbo diesel engine into a new 2014 Ford Super Duty F-350 Lariat at its Kentucky Truck Plant — which produces the Ford Super Duty and Expedition, as well as Lincoln Navigator. Ford originally introduced the 6.7 liter Power Stroke engine in 2010.
“This is a significant milestone for an engine that was introduced just a few years ago,” said Doug Scott, Ford Truck group marketing manager. “Demand for the engine has outpaced our expectations; our customers love the combination of performance, towing capability, and fuel economy.”
For the 2014 model year Super Duty trucks, the 6.7 liter Power Stroke V8 delivers 400 horsepower and 800 lb.-ft. of torque at 1,600 RPM, as well as class-leading fuel economy, while adding more fueling flexibility and meeting stringent emissions standards. In the F-450 pickup, the 6.7 liter engine enables a tow rating of up to 24,700 pounds, and 26,600 pounds in the F-550 chassis cab.
As enthusiasts of The Blue Oval’s Super Duty pickup trucks and the Power Stroke engine undoubtedly know, Ford is the only truck maker that designs, engineers, and builds its own diesel engine and transmission combination — allowing the powertrain to work seamlessly with all chassis components and vehicle calibrations. This approach, according to Ford, enables its engineers to optimize the truck’s performance across the entire lineup.
“Our Super Duty customers are no-nonsense, no-compromise individuals,” said Joe Bakaj, vice president of powertrain engineering. “Those are the attributes our team took to heart when engineering this diesel engine so we can deliver Built Ford Tough capability, reliability and enhanced productivity.”
Notable advantages of Ford’s 6.7 liter Power Stroke V8 include:
- Compacted graphite iron engine. Stronger than cast iron, the block structure is optimized for reduced weight and maximum strength to meet the demands of higher horsepower and torque
- Advanced inboard exhaust and outboard intake architecture – an automotive-industry first for a modern production pickup truck diesel engine – reduces overall exhaust system volume, which leads to better throttle and turbo response for the customer; additionally, reduced exhaust system surface area minimizes heat transfer to the engine compartment and improves noise, vibration and harshness performance
- Engine architecture enables easier service work for all major engine components, potentially reducing downtime
- Turbocharger is uniquely center-mounted on a pedestal low in the back of the valley for improved NVH control
- High-pressure fuel system injects fuel at more than 29,000 psi. The system delivers up to five injection events per cylinder per cycle, using eight-hole piezo injectors to spray fuel into the piston bowl. The direct-injection system is calibrated and phased for optimum power, fuel efficiency and NVH performance
- Aluminum cylinder heads for reduced weight; the mid-deck construction with dual water jackets provides increased strength and optimal cooling; six-head bolts, instead of four as found on other engines, help improve sealing and maintain cylinder integrity
- Compatible up to B20 biodiesel, allowing greener fueling options of up to 20 percent biodiesel and 80 percent petroleum diesel
In addition, Ford has refreshed the 2015 Super Duty lineup, with the biggest change being significant improvements to the 6.7 liter Power Stroke engine — which carries the “second generation” designation.
