  • Automotive catalytic aftertreatment system
    Patent number: 9789442
    Abstract: A catalytic aftertreatment system for a diesel engine exhaust gas is described. The system comprises a diesel oxidation catalyst (DOC) and an aftertreatment device located downstream of the diesel oxidation catalyst (DOC), which aftertreatment device requires periodic heat treatment, and means to generate a temperature increase within the aftertreatment device, said diesel oxidation catalyst (DOC) comprising an upstream zone of length from 0.5 to 2 inches (12.7-50.81 mm) of higher oxidation activity for hydrocarbons (HC) than the remainder of the diesel oxidation catalyst (DOC).
    Type: Grant
    Filed: April 20, 2016
    Date of Patent: October 17, 2017
    Assignee: Johnson Matthey Public Limited Company
    Inventors: Kieran Cole, Colin Newman, Isabel Tingay, Olivier Sonntag, Gudmund Smedler, Ruth Savage
