What is powerstroke

Twin pilot injection delivers smooth, quiet acceleration. A driver-controlled engine exhaust brake with on, off, and auto settings enables engine braking to help slow the truck down and control vehicle speed. The 6. However tough the work gets, you can always count on the Super Duty to get it done.

Varying factors such as horsepower, torque, fuel efficiency, and towing capacity come into consideration when picking out which PowerStroke engine is right for you. Need more information?

Follow Following. Utilization Of EGR One of the big differences in the third-generation Power Stroke is its use of exhaust gas recirculation to meet tougher emissions standards.

Relative to gas engines, the EGR process consists of reintroducing exhaust gases into the intake manifold in order to reduce nitrogen oxide NOx deposits into the air.

Like most EGR systems, the 6. Overall Impression Certainly not lacking in the power department, the first 6. They were known to leap off the line and build power quicker than the 7. However, when the aftermarket made it possible to add even more juice to these already potent engines, 6. Early engines were prone to head gasket or EGR cooler failures when subjected to plus horsepower gains or prolonged, extreme towing conditions.

The head gasket problems have been blamed on both the engine's four-bolt per cylinder head design and its torque-to-yield head bolts, which are designed to flex in order to keep even pressure on the head gasket. Later versions of the 6. Torque increased to lb-ft at 2, rpm for the '05 model year due to revisions in the engine's electronic control system.

The iron block and head engine displace cubic inches, has a compression ratio of The new mill puts out hp at 3, rpm and lb-ft at 2, rpm. Like the 6. After just four years, Ford replaced the 6. It made hp and lb ft of torque, and was believed to be free of the problems that plagued the 6.

However, it never really shook off all the demons from its predecessor. The reliability was improved over the 6. In addition, the 6. The 6. Not only was this a huge risk for Ford, it was an expensive one: Ford had to assume production of one of its best-selling engines. However, many truck enthusiasts will tell you that it was well worth the risk for Ford.

In , the Ford Super Duty began using the 6. Initially, it produced hp and lb ft. However, just one year later, Ford gave it a new turbo, which gave the 6.

In , even more changes bumped the 6. However, the peak torque increased to - get ready for this- - lb ft. Would it escape the reliability woes that plagued the two previous generations of Power Stroke?

At first, predictions were guarded as early engines suffered from premature turbocharger failures.
