Abstract

The invention relates to a dosing module (10) for injecting a reduction agent in particular a urea water solution into an exhaust pipe of an internal combustion engine in particular of a self igniting internal combustion engine to reduce nitrogen oxides in the exhaust stream wherein the dosing module has a main cooling element (12) through which a cooling liquid flows in particular for cooling an injection valve (64) for the reduction agent. According to the invention an additional cooling element (14) through which the cooling liquid likewise flows in particular for cooling in the region of an electrical plug connection (22) and of an electromagnet (80) for actuating the injection valve (64) is placed on the basis cooling element (12) wherein a guide insert (30) for the cooling liquid is arranged in the main cooling element (12). As a result of the guide insert (30) priority cooling of the end section (72) of the injection valve (64) which is in direct contact with the hot exhaust stream of the internal combustion engine occurs. According to the invention reliable operation of the dosing module (10) is ensured even at ambient temperatures of 160°C and above.
