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.

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 for operating an internal combustion engine, a computer program product, a computer program, and a control and/or regulating device for an internal combustion engine make detection of an erroneously permanently closed intake valve for a cylinder of the internal combustion engine having more than one intake valve possible. Air and fuel are supplied to the cylinder of the internal combustion engine via a plurality of intake valves. The air and fuel are supplied to the cylinder via a shared duct, which opens into separate ducts for each intake valve of the cylinder. The separate ducts have the same volume. After an interruption of the fuel supply to the cylinder, the fuel supply is resumed. Starting at a first point in time of the resumption of the fuel supply, the fuel quantity supplied to one of the separate ducts is ascertained assuming a permanently closed associated intake valve. A second point in time since the resumption of the fuel supply, at which the separate duct would be completely filled with fuel for the first time if the associated intake valve were permanently closed, is ascertained from the ascertained fuel quantity. A check is performed of whether the cylinder has relatively more combustion misses between the first point in time and the second point in time than after the second point in time. In this instance, it is concluded that an intake valve of the cylinder is erroneously closed.

摘要： The invention relates to an apparatus and a method for controlling and regulating an internal combustion engine 6; via a transducer disk 16 on the crankshaft 12 and a pickup 15, the annular position of the crankshaft 12 is ascertained continuously, with gasoline direct injection valves, in which the fuel injection valves 5 receive the fuel 1 from a pressure-imposing electric fuel pump 9 via a fuel rail 7. A control unit 25 evaluates the output signals of the pickup 15 to determine the annular position and to ascertain the rpm; depending on the annular position, the control unit 25 trips injection and/or ignition pulses. According to the invention, to detect the phase relationship of the engine 6, the pressure course in the fuel rail sensor 8 is evaluated. Upon blowback at compression counterpressure of fuel-air mixture into one of the injection valves in the event of an incorrect phase relationship offset by 360° KW, this leads to a significant pressure increase in the fuel rail sensor 8; the fuel rail sensor signal is delivered to the control unit 25, and as a result by means of the control unit a reverse synchronization by 360° KW of the ignition and injection is effected, and the affected fuel injection valve 5 into which the blowback takes place is immediately closed.

摘要： A method for generating a signal (TAn) responsive to the induction air temperature of an internal combustion engine. The signal (TAn) for the induction air temperature is determined from a signal (TMot) for the temperature of the internal combustion engine, from a signal (TU) for the ambient temperature, and from a correction factor K. Correction factor K is a function of a signal (mL) and/or a vehicular speed signal (v), signal (mL) representing either the induction air quantity or the air mass of the internal combustion engine. To enable the most accurate possible simulation of induction air temperature, even under changing operating conditions, the signal (TAn) for the induction air temperature is filtered, it being possible to variably select the time constant (ZK) of the filter in response to rising and falling induction air temperatures.

摘要： A device for connecting an agricultural implement to a tractor, towing it and driving it, via a power take-off shaft, has a double drive (8) which includes two angle drives (15, 16) which are arranged one above the other and which are pivotable relative to one another via a bearing around a first axis. The double drive (8) is associated with a holding bracket (9) and with a support (36) supported thereon via springs. The support (36) has a bearing journal via which is connected to a transverse bar (7) so as to be pivotable around an axis. The transverse bar (7) serves to connect the implement to the catching hook of the lower steering arms (3) of the tractor (1). These permit a pivot movement around the axis. The support (36) ensures improved conditions when accommodating forces in the case of impacts.
