Corning aluminum titanate filters selected by Hyundai, Kia
20 April 2007
Corning announced that selected Hyundai and Kia diesel passenger car models in the European market will be equipped with Corning DuraTrap® AT filters. Corning began serial production of AT filters for Hyundai Kia Motors at the end of 2006.
Hyundai Kia Motors will first integrate the AT filter into the Kia Cee’d diesel passenger car, powered by a 1.6 liter diesel engine. Following the Cee’d, which will be launched in the late 2007, Hyundai Kia Motors will integrate the AT filter into other diesel passenger car models.
The AT filter is a wall-flow monolith (single unit) made of an aluminum titanate composition. Technical characterization of the AT material was presented by Corning during the 2007 SAE Congress (SAE paper 2007-01-0656). Corning is producing the filters in Erwin, NY.
The Hyundai Kia Motors contract represents the second application of Corning AT filters, which were first launched in 2005 on Volkswagen cars. Particulate filters on European passenger cars typically utilize substrates made of silicon carbide (SiC) from such suppliers as NGK, Ibiden, and Saint-Gobain.
