The Ammonia Slip Catalyst (ASC) is the last step before

Hydrocarbon injection into the exhaust pipe is used for keep-

that is injected by the so-called 7th injector is combusted in the
DOC, which increases the exhaust temperature downstream
of the DOC. The hot exhaust gases will remove unwanted sub-
stances in the DPF and SCR and thereby ensure the efficiency
of those components.
