EXHAUST EMISSION CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide technology capable of inhibiting clogging of a nozzle for injecting a reducing agent in an exhaust emission control device of an internal combustion engine.

SOLUTION: The exhaust emission control device comprises a turbocharger 5 having turbine blades 55 and a reducing agent supply means 7 provided downstream of and adjacent to the turbine blades 55 for supplying the reducing agent. Also the reducing agent supply means 7 is cooled by heat medium for cooling the turbine 5 so that temperature rise of the reducing agent supply means 7 is inhibited and thus the evaporation of the reducing agent is inhibited.
