Abstract
Methods and systems are provided for a high-pressure exhaust gas recirculation system. In one example, the high-pressure exhaust gas recirculation system comprises pressure seconds arranged on different sides of a valve. The pressure sensors are used to regulate exhaust-gas recirculate flow without a fixed orifice delta pressure sensor.
