  • Method for estimating charge air cooler condensation storage and/or release with an intake oxygen sensor
    Patent number: 9976503
    Abstract: Methods and systems are provided for estimating water storage in a charge air cooler (CAC). In one example, an amount of water in charge air exiting the CAC may be based on an output of an oxygen sensor positioned downstream of the CAC. Further, engine actuators may be adjusted to increase combustion stability and/or reduce condensate formation based on the amount of water exiting the CAC.
    Type: Grant

  • Methods and systems for indicating water at an oxygen sensor based on sensor heater power consumption
    Patent number: 9714619
    Abstract: Methods and systems are provided for indicating water at an oxygen sensor based on power consumption of a heating element of the oxygen sensor. In one example, water may be indicated at an oxygen sensor positioned in an intake of an engine responsive to power consumption of the heating element of the oxygen sensor increasing above a baseline level. Engine operating parameters may then be adjusted based on the water indication and the power consumption.

  • Humidity and fuel alcohol content estimation
    Patent number: 8763594
    Abstract: Methods and systems for an engine system including an exhaust gas sensor are disclosed. In one example, under a first engine fueling condition, an air-fuel ratio correction factor is determined based on an expected air-fuel ratio and an actual air-fuel ratio. During a second engine fueling condition and a third engine non-fueling condition, fuel alcohol content and ambient humidity, respectively, are determined based on the exhaust gas sensor and corrected based on the air-fuel ratio correction factor.
