Perkins last week launched its first Tier-4 Final emissions-compliant engines at the ConExpo trade show. The new 400F, the latest addition to its 400 Series range, meets Tier-4 final/Stage IIIB regulations, which take effect in January 2013 in the EPA above 25 horsepower and in the EU above 49.5 horsepower.
The engines’ compact three- and four-cylinder lineup features a 97 percent carryover of components from the previous tier engines. With minimum changes, little or no machine re-design is required for OEMs.
The engines add a compact after-treatment system, with flexible mounting arrangements to ease installation. The after-treatment uses passive regeneration, with systems in place to provide active regeneration capability, effectively burning the soot in the diesel particulate filter to keep performance levels high. The 400F series delivers fuel-consumption improvements, minimizing running costs and heat rejection, which provides ambient clearance.
Perkins marketing manager Allister Dennis told RER the engines will initially be manufactured in Perkins’ Griffin, Ga., plant, and later, as demand grows, in the U.K., China and Japan.
