Honeywell Set to Turbocharge 70% of US Diesel Light Truck Segment With Launch of Ford 2011 Super Duty Truck
With Ford adopting Honeywell turbo technologies to boost its 2011 Super Duty Trucks, Honeywell says it will be turbocharging 70% of the US diesel light truck segment. General Motors uses Honeywell turbo technologies in its light duty diesel trucks as well.
Ford’s new 6.7-liter Power Stroke engine in its F-250 and F-350 models uses Honeywell’s VNT DualBoost turbocharger, a design that uses a double-sided compressor wheel mounted on a single shaft. (Earlier post.) The single-unit turbo delivers benefits approaching that of a twin-turbo system, but in a smaller, more efficient package.
In addition, this design allows a Variable Nozzle Turbine (VNT) DualBoost turbo to drive ultra-high levels of EGR (exhaust gas recirculation) in line with 2010 US emissions standards that call for 80% reduction in NOx while maintaining the ability to achieve higher horsepower.
In addition to DualBoost, Honeywell also offers AVNT, a variable nozzle technology that was first introduced for light truck diesel engines in 2001. Honeywell AVNT turbochargers were first equipped on General Motor’s Duramax engines in 2003, and since then have been continuously refined to adapt to several engine architectural changes.
The enhanced turbo aerodynamics and a new center housing design have resulted in a new generation of AVNT turbos that enable the latest Duramax engine to deliver 18% more power compared to the 2004 engine while meeting the latest emissions standards that called for sharp reduction in NOx emissions.
