Fault detection and response techniques

Номер: US20120022762A1

Автор: Carlos A. Rosero

Принадлежит: Cummins Inc

Systems and methods for detecting, predicting and/or responding to faults are disclosed. In one form, a sensor can be operatively coupled to an engine system having a component and a control system is coupled to the sensor. The sensor can be structured to monitor the engine system and generate corresponding sensor information. The control system can be structured to: generate an operational signature based on the sensor information, estimate whether a fault (e.g., a mechanical fault of the component and/or a performance fault of the engine system) exists based on the operational signature, determine an engine operating mode adjustment if the fault exists and output the engine operating mode adjustment to an output device. Systems and methods for increasing the accuracy by which faults are detected and/or predicted are also disclosed. The engine operating mode adjustment can be applied to protect engine system components from being undesirably damaged to faults.

The invention relates to a method for simulating malfunctioning solenoid valves for an internal combustion engine by influencing an activation time and a deactivation time of the solenoid valve. A current with a specified modifiable current strength flows through the solenoid valve in order to achieve an opening and closing process. The closing process is forced after the current supplied to the solenoid valve is activated at the activation time, and the opening process is forced after the current supplied to the solenoid valve is deactivated at the deactivation time. The current is applied with a charging current strength prior to the activation time for the duration of a charging phase, and after the activation time, the current is increased to peak current strength and subsequently reduced to a holding current strength. Furthermore, after the deactivation time, the current strength is reduced to a deactivation current strength, and after a delay, the current strength (I) increases again as a result of induction. A variation of the value and/or duration of the current strength and/or an application of an additional magnetic force is used to simulate a premature activation, a delayed activation, a premature deactivation, and/or a delayed deactivation. 1.

A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

A CPU determines that misfires are occurring in a cylinder subject to determination of whether misfires are occurring when a value obtained by subtracting a rotation fluctuation amount ΔT30[n−2] from a rotation fluctuation amount ΔT30[n] is greater than or equal to a determination threshold. The rotation fluctuation amount ΔT30[n] is subject to the misfire determination. The rotation fluctuation amount ΔT30[n−2] is 360° CA earlier than the rotation fluctuation amount ΔT30[n]. When stopping fuel supply to a cylinder #1 and determining whether misfires are occurring in cylinder #4, the CPU determines whether misfires are occurring after executing a correcting process that corrects the determination threshold to a second determination threshold Δth2, which is less than a first determination threshold Δth1.

Принадлежит: PACCAR INC

In some embodiments, a fuel temperature sensor is located proximate to a vehicle component that is expected to experience fuel gelling, such as near or within a fuel filter, in order to obtain temperature information that accurately reflects the likelihood of fuel gelling occurring within the component. The proximate fuel temperature sensor can provide more accurate temperature information for components such as fuel filters that are installed at the periphery of the vehicle, compared to other temperature sensors that measure oil temperatures or other temperatures of centrally located vehicle components. In some embodiments, the vehicle is automatically started when the temperature indicated by the fuel temperature sensor falls below a startup temperature threshold value, and is automatically stopped after a predetermined time period or after the temperature reaches a shutdown temperature threshold value.

The disclosure relates to a method for determining a parameter characterizing the anti-knock property of a fuel using a test engine having at least one cylinder, wherein the fuel undergoes combustion inside the cylinder during the course of the method and the cylinder pressure generated by the combustion is detected using a pressure sensor. The pressure sensor has a linear pressure output signal curve. A parameter characterizing the anti-knock property of the fuel is calculated based on the output signal of the pressure sensor. The calculation is done using a mathematical model that considers the deviation of the pressure output signal curve of the pressure sensor being used from the pressure output signal curve of a pick-up sensor prescribed in the ASTM D2699 standard. Moreover, a test system to determine the anti-knock property of a fuel is disclosed.

A method for diagnosing an error in an internal combustion engine in which fuel is injected from a high-pressure accumulator into associated combustion chambers with the aid of multiple fuel injectors , the method comprising:ascertaining a first value that represents a static flow rate of fuel through one of the fuel injectors;ascertaining a second value that represents a running smoothness of the internal combustion engine;if at least one of the first value and the second value deviates from a respective one of a first reference value and a second reference value, deducing an error; andassigning the error to at least one of (1) one of the fuel injectors, (2) at least one further component of the internal combustion engine, and (3) at least one operating phase of the internal combustion engine on the basis of deviations of the first value and the second value from the respective first reference value and the second reference value.17. The method as recited in claim 16 , wherein at least one of:the at least one further component of the internal combustion engine includes at least ...
