Exhaust system for use in exhaust pipe of spark ignition engine of car, has aeraulic deflector fixed at level of junction between upstream conduit and flexible controller and arranged without contacting external wall of flexible controller

摘要

The system has an upstream conduit (4) connected to an engine of a vehicle. A downstream conduit is connected to a case of the vehicle. A flexible controller (7) decouples the upstream conduit and the downstream conduit from each other. An aeraulic deflector (2) is fixed at a level of a junction between the upstream conduit and the flexible controller and covers a part of an external wall (10) of the flexible controller. The deflector is arranged without contacting the external wall. Distance between the deflector and the external wall is 5mm. The deflector is made of metal.
