Corning will begin supplying a new, advanced diesel particulate filter to light-duty vehicle manufacturers later this year.
The new Corning DuraTrap AT filter uses an advanced ceramic material and monolithic design to deliver a filtration efficiency of more than 90%. This new filter also provides excellent pressure drop performance to help minimize the impact on engine power output. The Corning DuraTrap AT filter can be used in either catalyzed or uncatalyzed applications.
It joins the DuraTrap RC filter, targeted at medium- and heavy-duty diesels.
The DuraTrap AT filter has a cellular structure with individual channels open and plugged at opposite ends. Exhaust gases enter the open end, flow through the pores of the cell walls, and exit through the adjacent channel. Soot particles are too large to flow through the pores, and they collect on the channel walls. Periodically, the filter is regenerated—or heated—to consume the soot and clean the filter.
The DuraTrap AT uses an advanced aluminum titanate composition in a monolithic structure.
Concurrent with the product announcement, Corning executives told their shareholders that the company expects the diesel market “to represent a strong growth opportunity for the company.“
In 2001, Corning posted just $12 million in sales of its diesel products. In the first three months of 2005, however, sales have already topped $20 million.
