    摘要: A method for diagnosing a malfunction of a sensor system in an air system of an internal combustion engine, said sensor system comprising a first air state sensor, a second air state sensor and a third air state sensor, wherein a first value and a second value of a first comparison variable are ascertained in two different ways in an overall calculation step such that the result of a comparison between the first value and the second value is a function of each of the output variables of the first, second and third air state sensors and wherein in a fault detection step, said method recognizes as a function of the comparison between said first value and said second value of the comparison variable that a fault exists in the sensor system.

    摘要: A method for checking the functioning of a ventilation apparatus for ventilating a crankcase connected via the ventilation apparatus to an air supply system of the internal combustion engine includes: determining a pressure difference between an ambient pressure and a crankcase pressure in the crankcase; identifying a fault in the ventilating apparatus as a function of the pressure difference if an enabling condition is met; the enabling condition being met if an air mass flow in the air supply system, filtered by a low-pass filter, exceeds a first threshold value in terms of absolute value.

    摘要: Systems and methods for leveraging a preliminary plant model to create a detailed physical plant model are presented. The system stores instances of component primitives, and can utilize stored geometries of the component primitives to identify a plurality of physical components to form a physical plant model. The physical plant model can realize at least a portion of the component runs based on equations and mapping definitions that establish relationships among the geometries of the equipment and piping. The components of the physical plant model can be mapped to catalog items based on the geometries of the components. After translation, a bill of materials listing the physical plant model components can be produced.
