  • Publication number: 20150198122
    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: 9051892
    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: 8984878
    Abstract: An internal combustion engine has a cylinder head having at least one cylinder. A cover is connected to the cylinder head and covers the cylinder and related valve train components. An exhaust gas turbocharger powered by the engine's exhaust system delivers compressed gasses to the intake system. An exhaust gas recirculation system branches off from the exhaust system downstream of the turbocharger and feeds into the intake system upstream of the turbocharger. A coolant-fed charge air cooler is disposed between the cylinder head and the cover, and at a point that is a geodetically highest point in the intake system when the internal combustion engine is in an installed position. This configuration prevents any liquid that has condensed out of the charge air during cooling from collecting in the cooler and/or in the intake system between the cooler and the at least one cylinder.

  • Patent number: 8815188
    Abstract: A method for monitoring a reducing agent solution composition in an exhaust gas system of an internal combustion engine with metered injection of the reducing agent solution upstream of an SCR catalytic converter comprises metering injection of the reducing agent solution into the exhaust gas stream, determining a measured variable of a change in water content in the exhaust gas stream in response to the injected reducing agent solution, and determining at least one indicator value of a composition of the reducing agent solution at least based on the determined measured variable. In this way, deviations from the standard composition may be taken into account during metering or be displayed as an error.

  • Publication number: 20130247567
    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.
