    摘要: A method and a device for monitoring the intake manifold pressure of an internal combustion engine in which a measured signal for the intake manifold pressure is compared with a reference signal for the intake manifold pressure. For a deviation of the measured signal for the intake manifold pressure from the reference signal for the intake manifold pressure, a tolerance range is predefined for error-free operation of the intake and/or exhaust valves of at least one cylinder of the internal combustion engine. A check is made whether the measured signal for the intake manifold pressure deviates from the reference signal for the intake manifold pressure by more than a predefined tolerance range. In this case an erroneous operation of the intake and/or exhaust valves is detected; otherwise an error-free operation of the intake and/or exhaust valves is detected.

    摘要: A method and a device for operating an internal combustion engine having a plurality of cylinder banks which allow a simple diagnosis of a faulty deactivation of the gas exchange of at least one cylinder bank, or a simple determination of the ambient pressure. In the process, in addition to at least one first cylinder bank having activated gas exchange of at least one cylinder, a deactivation of the gas exchange of all cylinders of at least one second cylinder bank is initiated in at least one operating state of the internal combustion engine. The at least one second cylinder bank is assigned a separate intake tract. In the at least one operating state, a variable that is characteristic for the pressure in the intake tract of the at least one second cylinder bank is measured and evaluated for the presence of undesired pressure pulsations.

    摘要: A method and a device for operating an internal combustion engine including at least one cylinder are described, the at least one cylinder including at least one intake valve and at least one exhaust valve and a diagnosis of at least one erroneous intake valve or at least one erroneous exhaust valve is made possible without using a position acknowledgment. A gas exchange of the at least one cylinder is diagnosed thereby. For detection of at least one intake valve or exhaust valve for the existence of an erroneous valve position, at least one intake valve or exhaust valve of the at least one cylinder different from at least one intake valve or exhaust valve to be detected is brought into a predefined position, which is selected in such a way that the gas exchange of the at least one cylinder in the case of an erroneous valve position of the at least one intake valve or exhaust valve to be detected differs significantly from the gas exchange of the at least one cylinder for the case of an error-free valve position of the at least one intake valve or exhaust valve to be detected, a value characteristic for the gas exchange of the at least one cylinder being ascertained, this value being expected at the moment for an error-free state of the set valve positions of the at least one intake valve and the at least one exhaust valve of the at least one cylinder, the actual value characteristic for the gas exchange of the at least one cylinder being ascertained and an error in the position of the at least one intake valve or exhaust valve to be detected is recognized as a function of the deviation in the actual value from the expected value.

    摘要: A method and a device for operating a drive unit provide a switch between half-engine operation and full-engine operation. A switch takes place between two operating states of a first component of the drive unit as a function of a first performance quantity of the drive unit. A switch takes place between two operating states of a second component of the drive unit as a function of a second performance quantity of the drive unit. A check is performed whether switching between two operating states of the second component results in a shift of the first performance quantity over a switching threshold for switching between two operating states of the first component, and if so, the switch between the two operating states of second component is delayed until a switch between the two operating states of first component has occurred.
