Corning DuraTrap - Particulate Filters for Light-Duty Diesel Emissions Systems Brochure

Diesel engines are an increasingly popular choice for fuel-efficient passenger cars and light-duty trucks. Advanced filters support the drive to improve fuel efficiency and meet tighter regulations. Corning® DuraTrap® AT diesel particulate filters use advanced materials and monolithic design to deliver:• High filtration efficiency • Excellent pressure drop performance• Enhanced durability Clean Diesel Made PossibleParticulate filters for diesel emissions systems Corning® DuraTrap® AT FiltersCorning’s aluminum titanate (AT) composition enables high performance light-duty filters by combining low coefficient of thermal expansion (CTE) with high heat capacity.Porous Material* Aluminum Titanate Silicone Carbide (TiAl2O5) (SiC)CTEc (x10-7/°C)Intrinsic Density (g/cm3)Volumetric Heat Capacity @ 500°C (J/cm3 K) 10 45 3.40 3.24 3.60 3.63 Asymmetric Cell Technology (ACT): larger inlet, smaller outlet** Performance Corning DuraTrap® AT filters use a stabilized aluminum titanate for outstanding performance and durability. Introduced in 2005, these filters have been proven in millions of vehicles. Corning’s aluminum titanate material provides low thermal expansion to enable durable monolithic construction that allows for:• Low pressure drop and excellent regeneration efficiency to help improve fuel consumption• Increased ash storage capacity and larger filtration surface area compared to segmented filters Additionally, its engineered pore structure enables customers to meet particulate mass and number emissions regulations worldwide. Innovative Design The extrude to shape monolithic design can be produced in a variety of sizes and optimized for systems with space constraints and diverse configurations. Corning’s innovative asymmet- ric cell technology (ACT) is an option that helps manage lifetime pressure drop requirements and provides Relative Coated Filter Pressure Drop on Engine Dynomometer at 6g/L Soot Load*Corning® DuraTrap® AT FiltersBrazilCorning International São Paulo Phone: 55-11-3089-7400ChinaCorning (Shanghai) Company, Ltd.
