A new 2008 model year Ford F-Series Super Duty pickup on sale in early 2007 will have a new 6.4-litre ‘Power Stroke’ diesel engine that will be the automaker’s cleanest and quietest diesel ever sold in America.

Ford said the combination of newly available ultra low-sulphur diesel fuel and a diesel particulate filter will result in particulate emissions equivalent to petrol engines.
The new Super Duty will be launched at the Texas state fair in Dallas on 28 September.
The redesigned diesel engine will displace 6.4-litres, which is a 400cc increase over the current six-litre V8. It will be the first pickup engine in North America to use a high precision, high pressure, common-rail fuel injection system featuring piezo-electric injectors.
The diesel particulate filter scrubs black smoke from exhaust gases and periodically cleans itself via engine controls.

By GlobalDataFord said diesel engines have become the powertrain of choice for heavy duty pickup truck buyers in the US because they provide more torque for maximum towing and load hauling.
Since 2001, annual diesel truck registrations have increased from about 400,000 to more than 500,000 today, and Ford is the industry leader, having sold 1.3m diesel-powered F-Series pickups in the US since 2001. On an annual basis, Ford sells more diesel-powered pickup trucks than Chevrolet and Dodge combined, it claimed.
Nearly three-quarters of all Ford Super Duty trucks are sold with the current Power Stroke diesel.
Its warranty and roadside assistance package covers diesel engines for five years or 100,000 miles.
Ford said the new low-sulphur fuels that make diesels cleaner to operate will help future growth in the US. From October, US government regulations will require ultra low-sulphur diesel to be available across the country.
High sulphur content in diesel fuel tends to clog the most advanced diesel engine emissions controls, in much the same way that lead formerly used in petrol damaged catalytic converters. The new fuel will contain 97% less sulphur than conventional diesel, with the sulphur reduced from 500 parts per million (ppm) to 15 ppm.
Compared with the diesel engines of 10 years ago, today’s diesels have 80% lower particulate emissions, 70% lower nitrogen oxide (NOx) emissions and 15% improved fuel consumption, according to the Diesel Technology Forum.
The US EPA estimates that emissions of particulate matter will be further reduced by 250,000 tons per year, and emissions of NOx will be reduced by 4m tons per year, when the entire US diesel engine fleet has been fully turned over to clean diesel technology by 2030.
Since diesel engines are able to extract more energy from a given quantity of fuel, they can also help reduce CO2 emissions through improved fuel economy.
The US Department of Energy estimates that a 30% penetration of clean diesel technology in the US passenger vehicle market by 2020 would reduce net crude oil imports by 350,000 barrels per day.
