2018 2 28ensp;0183;ensp;Abstract NOx adsorber catalyst systems have been developed to control NOx emissions from partial lean burn gasoline engines and from diesel engines.The adsorbers, which are incorporated into the catalyst washcoat, chemically bind nitrogen oxides during lean engine operation. After the adsorber capacity is saturated, the system is regenerated during a period of rich engine operation,
