  • Patent number: 7832384
    Abstract: An internal combustion engine includes a crankcase and a cylinder head which covers a cylinder of the crankcase and in which a fresh-gas channel and an exhaust-gas channel are made which open on a cylinder-head longitudinal side and are connected to in each case a fresh-gas line and an exhaust-gas collection line, and wherein there is an exhaust-gas recirculation system, including an exhaust-gas recirculation line and a control valve. An internal combustion engine having an exhaust-gas recirculation system is provided, in which the exhaust-gas recirculation system remains uninfluenced by the exhaust-gas collection line which is hot during operation. This is achieved in that the exhaust-gas recirculation system is arranged on that cylinder-head side which lies opposite the fresh-gas line and the exhaust-gas collection line.
