摘要： Embodiments for estimating intake air humidity in an engine are provided. In one example, an engine method comprises adjusting an engine parameter in response to intake air humidity estimated based on a concentration of one or more engine-out emissions. In this way, one or more exhaust emission sensors may be used to estimate intake air humidity.

摘要： A fuel injector diagnostic is disclosed. In one example, the diagnostic can determine if that amount of fuel injected or the timing of start of injection is degraded. Thus, the fuel injector diagnostic method can distinguish between different types of injector degradation.

摘要： A method for responding to an existing or incipient surge condition of a turbocharger coupled to an engine of a motor vehicle is provided. The method comprises receiving a signal responsive to an operating condition of the turbocharger and adjusting one or more operating parameters of the motor vehicle when a power of the signal, integrated over a pre-selected range of non-zero frequencies, exceeds a pre-selected threshold. Other embodiments provide related systems for responding to an existing or incipient surge condition of a turbocharger.

摘要： A method and system for monitoring proper connection between a valve/separator and an intake system through a crankcase ventilation system. A dielectric hose has an electrically hose conductive connector mechanically connectable to either: (a) an electrically conductive valve/separator connector, or (b) an electrically conductive intake system connector. An electrical circuit detects electrical continuity through the hose connector and the one of the valve/separator connector or the intake system connector mechanically connectable to said hose connector.
