  • Internal combustion engine with an exhaust-gas recirculation and method for operating an internal combustion engine
    Patent number: 8555864
    Abstract: An internal combustion engine has a high-pressure exhaust-gas recirculation line and a low-pressure exhaust-gas recirculation line with a low-pressure exhaust-gas recirculation valve. The low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system downstream of a turbine of an exhaust-gas turbocharger and opens into a fresh-air system upstream of a compressor of the exhaust-gas turbocharger. An exhaust-gas flap is disposed in the exhaust-gas system downstream from where the low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system. At least one pressure sensor is disposed in the low-pressure exhaust-gas recirculation line and configured such that the at least one pressure sensor determines a pressure difference in the low-pressure exhaust-gas recirculation line between a point upstream of the low-pressure exhaust-gas recirculation valve and a point downstream of the low-pressure exhaust-gas recirculation valve.
