Corning and Changan Automobile Partner on Gasoline Particulate Filters in China
Corning® DuraTrap® GC gasoline particulate filters will be integrated into the emissions control systems of Changan’s next generation of vehicles to help reduce fine particulate emissions.
Changan Automobile has chosen Corning Inc. as its supplier of gasoline particulate filters (GPF). Corning® DuraTrap® GC gasoline particulate filters will be integrated into the emissions control systems of Changan’s next generation of vehicles to help reduce fine particulate emissions, enabling the automaker to meet the upcoming China 6 light-duty vehicle emissions standards.
Starting in 2015, Corning and Changan began joint research and development activities around GPF technology, establishing a project team and running experiments to prepare for the China 6 standards. The technology solutions they developed, including the integration of DuraTrap GC filters into the emissions control system of Changan’s powertrain designs, are based on this research and will be available starting on Changan’s first China 6 engine platform, H15T. This platform has reportedly consistently succeeded in meeting tighter China 6 gaseous and fine particulate emissions limits. Vehicles on this engine platform, equipped with DuraTrap GC filters, will begin production at the end of 2018.
“We are very pleased to announce this next phase of cooperation between Changan and Corning, which is the product of years of effective collaboration and builds on Corning’s decades-long experience working with major automakers in China and other international markets on emissions control solutions,” said Annie Wang, commercial director for Corning Environmental Technologies, China. “Corning is proud to be able to contribute meaningfully to China’s clean-air initiatives, and foresees the market for DuraTrap® GC filters in China growing as more vehicles leverage this technology to help reduce particulate emissions.”
According to Corning, DuraTrap GC filters are designed and optimized to help automakers effectively reduce fine particulate emissions, such as PM 2.5, from gasoline engines. The filters feature a new cordierite-based material composition with an engineered ceramic microstructure that reportedly delivers high filtration efficiency of fine particulates while maintaining engine performance with low back pressure. A range of wash coat loading needs are also supported for additional catalytic activity to help address tighter gaseous emissions standards. Once emissions regulations are fully adopted in China and Europe, Corning expects its gasoline particulate filter business to add an estimated $500 million in annual sales.
