Problems solved by technology

The large relative movements between the exhaust pipe sections of the exhaust pipe system therefore create the risk that the cooling water flow channels at the transition between two adjacent exhaust pipe sections are no longer sufficiently sealed, This creates the risk of cooling water overflowing

Abstract

The invention relates to a discharge pipe system used for the multiple cylinder internal combustion engine, including a plurality of discharge pipes, wherein each discharge pipe segment has a joint flange for jointing the corresponding discharge pipe segment to the cylinder of the internal combustion engine, and each discharge pipe segment also has an exhaust gas flow passage, at least two exhaust gas longitudinal chambers surrounding the exhaust gas flow passage and a cooling water flow passage surrounding the exhaust gas flow passage and the exhaust gas longitudinal chambers. Two adjacent discharge pipe segments are assembled in the condition of using the exhaust gas compensator so that the exhaust gas flow passage of the discharge pipe segment and the first exhaust gas longitudinal chamber of the discharge pipe segment surrounding the corresponding exhaust gas flow passage are directly complemented and the second gas exhaust longitudinal chamber of the gas exhaust segment surrounding the corresponding first gas exhaust longitudinal chamber and cooling water flow passage of the gas exhaust segment surrounding the second gas exhaust longitudinal chamber are complemented from eachother when the exhaust gas compensator is arranged in the center.

Description

technical field [0001] The invention relates to an exhaust pipe system for a multi-cylinder internal combustion engine, which has a plurality of exhaust pipe sections, wherein each exhaust pipe section has a connecting flange for connecting the respective exhaust pipe section to a cylinder of the internal combustion engine, Each exhaust pipe section also has an exhaust gas flow channel, at least two exhaust gas longitudinal chambers each surrounding the exhaust gas flow channel, and a cooling water flow channel surrounding the exhaust gas flow channel and the exhaust gas longitudinal chamber. Background technique [0002] An exhaust pipe system for a multi-cylinder internal combustion engine is known from DE 196 44 707 C2, which is assembled from a plurality of exhaust pipe sections. Each exhaust pipe section of the exhaust pipe system disclosed there has a connecting flange for connecting the exhaust pipe section to a cylinder head connection of a cylinder of an internal co...
