  • Patent number: 7584749
    Abstract: An arrangement for recirculation of exhaust gases of a supercharged combustion engine in a vehicle. An inlet line for supply of compressed air to the combustion engine. The inlet line includes a charge air cooler for cooling the air. A return line connects the exhaust line to the inlet line and the return line recirculates exhaust gases from the exhaust line to the inlet line. The return line includes an EGR cooler for cooling the recirculating exhaust gases. The EGR cooler and the charge air cooler are arranged close to the combustion engine on the cold side of the combustion engine where a branched inlet pipe is fastened.

  • Publication number: 20080135028
    Abstract: The present invention relates to an arrangement for recirculation of exhaust gases of a supercharged combustion engine (1) in a vehicle. The arrangement comprises an inlet line (10) for supply of compressed air to the combustion engine (1). The inlet line (10) comprises a charge air cooler (11) for cooling the air. The arrangement also comprises a return line (15) which connects the exhaust line (6) to the inlet line (10) so that it is possible, via the return line (15), to recirculate exhaust gases from the exhaust line (6) to the inlet line (10). The return line (15) comprises an EGR cooler (17) for cooling the recirculating exhaust gases. The EGR cooler (17) and the charge air cooler (11) are arranged close to the combustion engine (1) on the cold side of the combustion engine (1) where a branched inlet pipe (24) is fastened.

  • Publication number: 20070245716
    Abstract: An arrangement for recirculation of exhaust gases of a combustion engine comprises a return line which connects an exhaust line of the engine to an inlet line of the engine to recirculate exhaust gases from the exhaust line to the inlet line. At least one EGR cooler for cooling the recirculating exhaust gases in the return line. The EGR cooler is fitted close to the combustion engine so that a vertical plane extending substantially centrally between an inlet portion and an outlet portion of each of the EGR coolers for recirculating exhaust gases is substantially parallel with a vertical plane through the combustion engine.
