Exhaust gas pipe system for a rail vehicle

摘要

The system (4) comprises a fuel consumable main operating unit (12) that is connected to a main operating exhaust pipe (8). A fuel consumable auxiliary operating unit (10) is connected to an auxiliary operating exhaust pipe (6) having an end portion (16) and an exhaust port (14). The exhaust port of the auxiliary operating exhaust pipe is arranged into the main operating exhaust pipe, such that a negative pressure is generated in the auxiliary operating exhaust pipe by an exhaust gas flow (20) in the main operating exhaust pipe.
