Abstract
An automotive exhaust aftertreatment system includes a three-way catalyst (TWC) fluidly coupled to an internal combustion engine and a muffler, a selective catalytic reduction (SCR) unit located downstream from the TWC and upstream from the muffler, the SCR unit configured as a NOx catalytic converter and a hydrocarbon (HC) trap, and an electrically heated catalyst (EHC) located downstream from the SCR and upstream from the muffler, the EHC configured as a catalytic converter for the trapped HCs once the HCs are released from the SCR.
