Exhaust apparatus for motor vehicles

摘要

The system has an exhaust gas converter with an exhaust gas cooler (1) mounted before it. The cooler has a housing (2) enclosing the exhaust gas channel (18) with inlet and outlet openings (6,8) and an e.g. cylindrical side wall (3) whose essentially entire inner surface (22) forms a cooling surface exposed to the exhaust gas. At least one cooling air channel (11) within the exhaust gas channel passes through the housing.
