摘要： An exhaust system (1) of an internal combustion engine (2), comprising an engine exhaust conduit (4) and an aftertreatment system (3) including a main exhaust conduit (5) connected to the engine exhaust conduit and at least one catalytic converter (9), further comprising a bypass conduit (10) for allowing exhaust gases to bypass the aftertreatment system, an adjustable bypass port and an adjustable main port for controlling each of a flow of exhaust gases carried via the bypass conduit and the aftertreatment system respectively, and a control system configured to determine an amount of hydrocarbons currently stored in the catalytic converter and control the main port and the bypass port in independence of each other based on at least said amount of hydrocarbons and/or a temperature within the aftertreatment system.

摘要： The invention concerns an arrangement for the recirculation of exhaust gases in a combustion engine. An inlet pipe (4) is arranged for incoming air (6) intended to be supplied to the cylinders of the engine, which inlet pipe (4) demonstrates an inlet end (8), and an EGR injector (10) for the supply of recirculating exhaust gases (12) to the incoming air (6). The EGR injector is arranged in the inlet pipe (4) such that the outlet part (14) of the EGR injector is located essentially outside of the inlet duct (4). The outlet part (14) comprises several outlets (16) distributed in the longitudinal direction of the outlet part, and the said several outlets (16) are asymmetrically distributed around the circumference of the outlet part.
