Abstract
A system for purifying exhaust gas includes a controller to predict a possibility of ammonia (NH) slip occurring at the rear end of a selective catalytic reduction on a diesel particulate filter (SDPF) by comparing a convective heat transfer value (h) with a first predetermined value. The controller determines whether an engine is rapidly accelerated, and performs a control to prevent introduction of ammonia downstream of the SDPF when the ammonia slip is predicted to occur.
