摘要： In the processing circuit of the control device, the stress of the compressor impeller is acquired every predetermined control cycle. Setting a small section, and calculating a small section average value and a small section amplitude are repeatedly executed. Setting a middle section, and calculating a middle section average value and a middle section amplitude are repeatedly executed. The first damage value is calculated based on the small section average value and the small section amplitude. The second damage value is calculated based on the middle section average value and the middle section amplitude. An estimated value of the deterioration degree of the compressor impeller is calculated based on the integrated value of the first damage value and the second damage value.

摘要： An internal combustion engine-based system includes an internal combustion engine. The internal combustion engine-based system includes an engine interrupt connected to the engine. The engine interrupt is configured to selectively stop the operation of the engine. The internal combustion engine-based system includes a controller in communication with the engine interrupt. The internal combustion engine-based system includes a carbon monoxide detector in communication with the controller. The controller uses the engine interrupt to stop the operation of the engine when the carbon monoxide detector provides the controller with signals that are representative of a carbon monoxide level proximate the internal combustion engine that together form a trend of building carbon monoxide amounts over a set time interval.

摘要： A method for estimating at least one ring-related parameter related to at least one piston ring may include estimating a bore distortion of a cylinder bore. The bore distortion may include a plurality of bore distortions corresponding to a plurality of respective piston locations within the cylinder bore. The method may also include receiving the bore distortion in a ring performance model configured to dynamically estimate a plurality of ring-related parameters associated with combustion in the cylinder bore during operation of the internal combustion engine. The ring performance model may be configured to receive a static data signal indicative of static parameters and a dynamic data signal indicative of dynamic parameters related to operation of the internal combustion engine. The ring performance model may be configured to estimate at least one ring-related parameter related to at least one piston ring during operation of the internal combustion engine.

摘要： 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.

摘要： 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 washer defines an external surface and includes a central cavity for engaging the elongated body of the elongate fastener therein. The mounting boss includes a first portion and a second portion. 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.

摘要： The aim of the invention is to economically produce a pressure measuring sensor element, and relates, according to one aspect, to a method for producing a pressure sensor measuring element for a pressure sensor which comprises at least one membrane and a covering protecting the membrane, the pressure sensor element being produced in a layer-by-layer generative production method. This makes it possible to, for example, easily construct a combination sensor for detecting pressure and an additional parameter. It is also possible to structures for reinforcement or for influencing resonant frequency or for influencing heat conduction.

摘要： Detecting manipulation of an SCR catalytic converter system of a motor vehicle. A control command (61) for the SCR catalytic converter system, transmitted from a control unit outside the motor vehicle, is received by the motor vehicle. Manipulation is detected (57) if a response (55) of the SCR catalytic converter system to the execution (54) of the control command (61) does not correspond to expectation. Embodiments also relate to monitoring manipulation of the SCR catalytic converter system. Here, a control command (61) for the SCR catalytic converter system is transmitted (41) to the motor vehicle (10) from a control unit (20) outside the motor vehicle.
