In 1994 Ford diesel engines became cleaner and far more powerful then they ever had been. The 6.0-liter International Diesel followed the highly successful 7.3-liter Ford Power Stroke Diesel in 2004. The engine was a third-generation diesel ,built as a temporary engine until Ford could meet the new Environmental Protection Agency diesel engine standards.
In 2006 Ford powered its trucks with the 6.0-liter Power Stroke Diesel with a compression ratio of 18.0-to-1. The power of the 6.0-liter engine allowed the F-250 to tow 15,000 pounds. The engine generated 325 horsepower at 3,300 rpm and 560 foot-pounds of torque at 2,000 rpm. The engine had excellent acceleration and was equipped with a five-speed Allison transmission.
Turbochargers boost engine pressure, increase the horsepower and decrease fuel consumption. Ford trucks employed the variable geometry turbo, or VGT. This type of turbo uses variable vanes to direct exhaust gas flow into the turbine. The technology allows the turbine to work efficiently at all engine speeds. Ford and all the automakers now regularly feature turbochargers in everyday vehicles to increase power and mileage.
The Power Stroke diesel gets average gas mileage for the amount of power. During a test drive under towing conditions, according to Diesel Power Mag.com, the 6.0-liter in the 2006 F-250 achieved 9.49 mpg. The mileage was lower compared to the Dodge Ram 3500, at 10.9 mpg, and the Chevy Silverado 2500, at 14.4 mpg.
Pros and Cons
The 2006 Ford 6.0-liter Power Stroke exhibited many advantages. The 6.0-liter engine had great power and good acceleration. The engine used EGR technology to lower emissions. Also the engine ran quieter. Early versions of the 6.0-liter engine had some problems with fuel injection and the emissions system, but by 2006 Ford had addressed most of the issues.
