  • Publication number: 20170314483
    Abstract: A device for predicting an exhaust gas recirculation rate of an internal combustion engine, which comprises an inlet system and at least one exhaust gas recirculation valve, is described. The device comprises a sensor arranged in the inlet system for determining the composition of the gas, a sensor for determining the position of the exhaust gas recirculation valve, and an evaluation apparatus. The evaluation apparatus is configured to determine and output a prediction of the exhaust gas recirculation rate based on a corrected estimate of the exhaust gas recirculation rate, wherein the estimate is based on the position of the exhaust gas recirculation valve and is corrected based on the composition of the gas as determined using the sensor.

  • Publication number: 20160251012
    Abstract: The present disclosure relates to an operating method for a motor vehicle having a hybrid drivetrain where in a demand check, at least one exhaust-gas after-treatment actual value, which characterizes a current exhaust-gas after-treatment actual state, is compared with an exhaust-gas after-treatment setpoint value, and if, in the event of a deviation of the exhaust-gas after-treatment actual value from the exhaust-gas after-treatment setpoint value, a demand for a measure is detected. The measure comprises supplying charge gas, which has recirculated exhaust gas, to the internal combustion engine during overrun operation. Also a capability check is carried out to detect conditions suitable for implementing the operating method.

  • Patent number: 9322367
    Abstract: Methods and systems are provided for estimating a fuel canister purge flow based on outputs of an intake manifold oxygen sensor. For example, during boosted engine operation when exhaust gas recirculation (EGR) is flowing below a threshold and purge is enabled, purge flow may be estimated based on changes in the sensor output while modulating a canister purge valve between an open and closed position. Then, during subsequent operation wherein EGR and purge flow are enabled, the output of the sensor may be adjusted based on the estimated purge flow.

  • Patent number: 9181862
    Abstract: The present disclosure provides systems and methods for adjusting an exhaust gas recirculation rate to provide accurate air-fuel ratio. The disclosure provides a method for calculating an exhaust-gas recirculation rate based on a measured exhaust-gas lambda and a turbocharger speed. Through the use of the exhaust-gas lambda and the turbocharger speed it is possible to calculate an exhaust-gas recirculation rate while dispensing with the difficult and unreliable determination of the mass air flow for determining an exhaust-gas recirculation rate, thus providing a stable method which further reduces fuel consumption and emissions.

The heating device is configured to perform a heating process for preheating the air that is fed to the internal combustion engine. A duration of the heating process and/or heat output given off by the heating device is controlled as a function of a variable approximately representing a state of ageing of at least one of the one or more exhaust gas treatment units.

  • Publication number: 20150267627
    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.
