Abstract

A device for diversion of condensate (50) from a cooler (28, 48) for combustion gas to an inlet (14) for the combustion gas of a combustion engine (10), comprising a condensate line (52, 54, 56, 60) between the cooler and the inlet. The condensate line branches to separate line sections (60) each leading to close to one of a number of inlet ports of the engine (10), with a valve (62) in each line section (60) for proportioning the condensate (50) to each inlet port in response to pressure differences at the inlet ports. It is thus possible to prevent risk of the engine being subject to water hammer due to the condensate diverted to the engine.
