Supplier Mann+Hummel Group of Ludwigsburg, Germany, has improved its position in North America.
The company will manufacture air filter systems and intake manifolds for engines used in three Ford Motor Co. vehicles: the Ford Fusion, Mercury Milan and Lincoln Zephyr.
Mann+Hummel manufactures plastic manifolds in Portage, Mich., for Ford's Duratec engines.
The air filter system and a coolant reservoir to be used on the three cars will come from Mann+Hummel's factory in Queretaro, Mexico.
The air filter systems were specially adapted for the acoustics of the Ford Duratec engines available on the cars -- a 160-hp, 2.3-liter inline-four or 221-hp, 3.0-liter V-6 on the Fusion and Milan and the V-6 on the Zephyr.
The resonator lies in the fender and takes up no additional space in the narrow engine compartment.
Final assembly takes place in Hermosillo, Mexico.
To meet tight environmental requirements in the so-called green states, including California, New York, Massachusetts, Vermont and Maine, Mann+Hummel has developed a hydrocarbon trap.
After an engine is shut off, it is possible for fuel residue to evaporate and escape through the manifold.
To prevent this, Mann+Hummel integrated a hydrocarbon-adsorbent element into the air duct. That element holds onto hydrocarbon molecules.
