  • Patent number: 6422222
    Abstract: An internal combustion engine has a plurality of cylinders which are arranged in two rows, two exhaust-gas turbochargers which are driven in each case by the exhaust gases from the cylinders of a cylinder row, and exhaust-gas recirculation. Two exhaust-gas discharge lines branch off, upstream of the respective exhaust-gas turbocharger, part of the exhaust gases from the cylinders of a cylinder row to be recirculated and supply this part to a common recirculation line. By way of the common recirculation line, the exhaust gases to be recirculated are supplied, downstream of the exhaust-gas turbochargers, to an air supply. At least one valve, which serves as an exhaust-gas recirculation valve and by which the quantity of recirculated exhaust gases can be set, is provided. The valve has a stop by which a communicating connection made between the two exhaust-gas discharge lines can be shut off.
