Abstract
A regeneration control apparatus for controlling, in an exhaust gas treatment apparatus of a diesel engine including a diesel oxidation catalyst (DOC) disposed in an exhaust passage of an internal combustion engine and a diesel particulate filter (DPF) disposed downstream of the DOC, execution of forced regeneration to remove an exhaust particulate matter (PM) which accumulates on the DPF through a temperature increase of the DPF, includes: a late-post injection amount determination part which determines a late-post injection amount. The late-post injection amount determination part is configured to determine an upper limit value of the late-post injection amount on the basis of an air excess ratio of exhaust gas flowing into the DOC obtained on the basis of a temperature index of the DOC.
