摘要：
A reducing agent for use in an internal combustion engine is a mixture of an ammonia-derived solid reducing material and a water-insoluble liquid in which the solid reducing agent is immersed. A reducing-agent supply device is provided for supplying a denitration catalyst with the reducing agent, such that the reducing agent is introduced into a portion of an exhaust passage of the internal combustion engine which is upstream of the denitration catalyst.
