Adjustment arrangement for adjusting boost pressure in combustion engine for vehicle, has cooling device that is connected in series with control valve for cooling the exhaust gas flowing through valve

摘要

The adjustment arrangement has a primary control valve (36) for bridging an exhaust turbine (22) of a turbo supercharger (10). A cooling device (30) is connected in series with the primary valve for cooling the exhaust gas (34) flowing through the primary valve. A secondary valve (38) is located parallel to the first valve and is connected with the cooling device. Independent claims are included for the following: (1) an exhaust system; (2) a combustion engine; (3) a method for adjusting boost pressure in combustion engine; and (4) a control device.
