摘要：The invention relates to an arrangement for a combustion engine (1) comprisingat least one cylinder (2), an intake (3, 4) for the supply of air, an exhaust outlet (9, 10) fordischarging exhaust gases, a further line (15) for recirculation of exhaust gases from saidoutlet (9, 10) to said intake (3, 4) for reduction of harmful emissions from the engine (1), acontrollable valve (16) arranged in said further line (15) and a turbocharger unit (11)comprising a first means (12) for absorbing energy from the exhaust gases and a means(14) for compressing air to said intake (3, 4). The invention is characterised in that itcomprises a second means (22) for absorbing energy from the exhaust gases, arrangeddownstream of said first means (12), for building a pressure in said outlet (9, 10) whichsurmounts the pressure in said intake (3, 4). The invention also relates to a method of theabove-mentioned kind. Through the invention, an improved arrangement, particularly fora diesel engine having an EGR system, is achieved, by means ofwhich a sufficient
propulsion pressure for the EGR gases is obtained, achieving a reduction of particularlythe NOx emissions.
