An intelligent electronic device (IED) may monitor wet stack residue buildup of a diesel engine. Once the wet stack residue accumulates to a certain amount, the IED may perform a mitigation procedure. Additionally, tracking wet stack residue buildup may allow an IED to attempt to prevent or reduce accumulation of the wet stack residue. The IED may track an operating power level of the diesel engine to estimate the rate of residue buildup.

A method for managing the sporadic anomalies of a power system of a motor vehicle, the system including a computer and a set of sensors. The computer including a memory area capable of receiving measurements made by the set of sensors and detecting anomalies on the basis of the measurements received, the anomalies of the system being defined in a predetermined list of sporadic anomalies at a given instant. The method including: detecting an anomaly; measuring the duration of the detected anomaly; if the measured duration is less than a predetermined duration threshold, and if the detected anomaly is present in the predetermined list of sporadic anomalies at the current instant, incrementing an occurrence counter; and if the value of the occurrence counter is greater than a predetermined occurrence threshold, confirming the detected anomaly as a sporadic anomaly.

A method and a device for performing diagnostics on an exhaust gas sensor includes a series circuit of a Nernst cell and a first other cell. The exhaust gas sensor has a first, a second, and a third connection where a voltage drop can be measured between the first connection and the second connection by the Nernst cell and a voltage drop between the second connection and the third connection can be measured by the first other cell. The diagnostic method has steps for feeding a direct or alternating current into the first, second, and third connections; for directly or indirectly sensing an electrical voltage potential at at least one of the first, second, and third connections; and for evaluating the voltage potential sensed to diagnose a short circuit or an open circuit in the Nernst cell and/or in the first other cell.

Methods and systems are provided for an electric turbocharger (e-turbo). In one example, a method may include monitoring an e-turbo parameter or an engine parameter, comparing the monitored e-turbo or engine parameter to a determined threshold value for the e-turbo or engine parameter, and signaling a status of the e-turbo in response to the monitored e-turbo or engine parameter differing from the determined threshold value by at least a threshold amount.

Disclosed is a method and a system for stimulating and communicating with floral objects. The system includes a base unit for communicating with the floral objects to read and stimulating physical and biological properties, and an electronic circuitry configured to be placed in reach of the floral objects. The electronic circuitry is capacitively coupled to the base unit and the floral objects. The base unit is able to create and communicate stimulated patterns to stimulate growth, biological properties of the floral object. The base unit generates stimulated pattern on receiving information and data from the electronic circuitry.

A method for operating an internal combustion engine with a motor, having a moving machine part and at least one machine element which retains the moving machine part and is subject to wear, such as, for example, a supporting, sealing, guiding or the like retaining machine element that is subject to wear during operation relative to the moving machine part, which machine element, because of the wear, is service-life-limiting for the operation of the internal combustion engine, wherein—for the operation of the internal combustion engine, a service-life-limiting time interval until the next maintenance of the internal combustion engine is specified, and—the internal combustion engine has a number of service-life-limiting machine elements, wherein for the at least one service-life-limiting machine element a remaining service life is forecast and the service-life-limiting time interval is determined therefrom.

A mounting system for retrofitting a vibration sensor to a machine component is provided. The mounting system includes an elongate fastener, a washer, and a mounting boss. The elongate fastener includes a fastener head and an elongated body defining a longitudinal top end and a longitudinal bottom end. The longitudinal bottom end defines a fastening end configured to engage with a corresponding fastening receptacle of the machine component.

The first portion includes an internal cavity defining a first cavity section configured to engage with the external surface of the washer, and a second cavity section to engage with the fastener head of the elongate fastener. The second portion defines a receiving port for receiving the vibration sensor.

A rocker arm grading system can comprise a grading tool. The grading tool can be used with a rocker arm to measure aspects of the rocker arm and determine a resulting valve lift. The grading tool can comprise a rocker arm jig comprising a pivot peg and a valve peg. A cam jig can comprise a cam arm. A cam pin can be mounted in the cam arm. A rocker arm can be removably mounted to the rocker arm jig. The rocker arm can comprise a radius on a bearing surface. A cam edge of the cam pin can press against the bearing surface. At least one measuring device comprising a wavelength emitting device paired with a wavelength detecting device can be configured to measure the radius of the bearing surface with respect to the pivot peg.

In a method for learning a mapping used by a computer, the mapping calculates a probability related to a categorization result using an internal combustion engine state variable as an input. The categorization result is a result of categorizing a state of an internal combustion engine into one of regions. The computer outputs the categorization result based on the calculated probability. The method includes inputting multiple training data to a training computer. The training data include the internal combustion engine state variable and the categorization result that is correct and associated with the internal combustion engine state variable. The method further includes updating the mapping based on the training data with the training computer. The training data are distributed to the regions and have a distribution density that is increased at locations closer to a border between the regions.
