摘要： A method performs a diagnosis of a lambda sensor of a “UEGO” type of an exhaust system for an internal-combustion engine. The lambda sensor includes a series of pins. The diagnosis method comprises steps of: heating the lambda sensor to cause the lambda sensor to reach an inner temperature that is higher than about 600° C.; polarizing a first one of the pins by connecting the first pin to a supply voltage through a first limiting resistance; measuring a voltage of all of the pins while the first pin is connected to the supply voltage; and diagnosing a presence of a short circuit to an electrical ground if the voltage of at least one of the pins is lower than a predetermined threshold. A control unit performs the diagnosis.

摘要： A device for diagnosing an exhaust gas sensor, in particular a linear oxygen probe, for an internal combustion engine. A diagnostic unit is configured to control a first and a second current source in a coordinated manner in order to generate a first and a second current. Each of the currents has a predefined polarity sign, and is designed to determine the first and/or second and/or third voltages applied at a first and/or second and/or third terminal when first and second currents flow and put the amounts of the voltages in relation to the coordinated currents such that line interruptions and/or short circuits can be detected at the first and/or second and/or third terminal.

摘要： A fault detection method is provided for detecting faults in an injector arrangement. The injector arrangement includes one or more piezoelectric fuel injectors connected in an injector drive circuit, and the injector drive circuit is arranged to control operation of the one or more piezoelectric fuel injectors. The fault detection method includes determining a sample voltage at a sample point in the injector drive circuit at a first sample time. The sample voltage is the voltage on an injector or is related to the voltage on an injector. The method further includes calculating a range of predicted voltages expected at the sample point at a second sample time following the first sample time, and determining the sample voltage at the sample point at the second sample time. The presence of a fault is detected if the sample voltage determined at the sample point at the second sample time is not within the range of predicted voltages.

摘要： A method of detecting faults in an injector arrangement in an engine. The injector arrangement comprises at least one fuel injector having a piezoelectric actuator, and the method comprises: charging the piezoelectric actuator during a charge phase (tC); attempting to recharge the piezoelectric actuator during a test phase (tT) which commences after a time interval (Δt) following the end of the charge phase (tC); sensing a current (IS) that flows through the piezoelectric actuator during the test phase (tT); and generating a short circuit fault signal if the sensed current (IS) reaches a first predetermined threshold current (ISC) which is indicative of a short circuit in the piezoelectric actuator.

摘要： The operating voltage is monitored in a microcontroller having associated output stages which are used to control components. In the case of over-voltage, the output stage is disconnected. Two technology-related, voltage monitoring devices working in different operating voltage ranges are provided. Due to the combination thereof, a highly precise disconnection threshold and a greater area for the operating voltage, which is to be monitored, can be obtained. If a malfunction of an over-voltage occurs, the output stages can be disconnected in a reliable manner.
