  • Patent number: 10323583
    Abstract: Embodiments for determining oxygen concentration using an oxygen sensor are provided. In one example, a method for determining oxygen concentration O2 in a gas flow of an internal combustion engine which is equipped with an engine controller and an oxygen sensor comprises determining the oxygen concentration O2,sens of the gas flow in a ceramic measurement cell of the sensor by current ISens which is detected by measurement and which flows when a constant voltage USens is applied and maintained, and correcting the oxygen concentration based on a pressure pSens at the measurement cell. In this way, the measured oxygen concentration may be corrected based on the pressure of the air at the sensor.

  • Patent number: 10202945
    Abstract: Embodiments are provided herein for controlling a motor-vehicle internal combustion engine fitted with a fuel injection system and an exhaust gas recirculation system. In one example, in a deceleration phase a closed exhaust gas recirculation circuit is formed, a mass (mcirc) of an air quantity enclosed therein is determined, a first oxygen content (O2,exh1, O2,man1) of the air quantity is detected, a test injection is carried out with an injection valve, a second oxygen content (O2,exh2, O2,man2) of the air quantity is detected, and the fuel mass (mfuel) injected in the test injection is determined from the mass (mcirc) of the air quantity and the first and the second oxygen content (O2,exh1, O2,man1, O2,exh2, O2,man2). The disclosure also relates to a corresponding device for controlling a motor-vehicle internal combustion engine fitted with a fuel injection system and an exhaust gas recirculation system.
