FIELD: physical and chemical processes.
SUBSTANCE: device for controlling emissions includes: a first catalyst comprising an electrohepable carrier and a first composition placed on an electrically heated support, and a second catalyst comprising a support and a second composition on the support. First composition contains aluminium oxide and the first platinum group metal (PGM). Where the second composition contains aluminium oxide and the second platinum group metal (PGM). Loading of the first composition is less than loading of the second composition. First catalyst is located upstream of the second catalyst.
EFFECT: described is an emission control device for an internal combustion engine with compression ignition.
