摘要：An emission control system for an internal combustion engine (1) includes aNOx catalyst (41) disposed in an exhaust system (40) of the internal combustion engineand having a property of promoting reactions for reducing NOx when a concentration ofa reducing substance in an exhaust gas becomes high, and reductant adding means (14,16, 17, P2) for adding a reducing agent to the exhaust gas flowing into the NOx catalystthrough the exhaust system. The emission control system further includes control means(80) for controlling the reductant adding means to add the reducing agent in the form ofdroplets to the exhaust gas.
