摘要： A method and a device for operating an internal combustion engine, which make possible a defined and reliable cutting in or cutting off a gas-exchange valve of a cylinder. In at least one operating state, at least one intake valve or exhaust valve of a cylinder is cut off or at least one cut-off intake valve or exhaust valve of the cylinder is cut in again, the at least one intake valve or exhaust valve being opened and/or closed using an operating element; and the operating element being switched off or switched on again using a coupling element. A response delay time is ascertained which is required for the operation of the coupling element for the switching off or switching on again the operating element. Furthermore, a switching time window is ascertained within which the operation of the coupling element is desired. Moreover, it is checked whether the switching time window is greater than the response delay time. In this case, a beginning of the switching procedure for cutting off or cutting in again the at least one intake valve or exhaust valve is established in such a way that the response delay time lies completely within the switching time window.

摘要： A method and a device for operating an internal combustion engine having multiple cylinders allows for an operating state of the internal combustion engine to be switched over as quickly as possible following the receipt of a switchover request. For this purpose, at least one intake or exhaust valve of a cylinder is switched off or at least one switched-off intake or exhaust valve of the cylinder is switched on again in at least one operating state of the internal combustion engine in response to the switchover request. With the receipt of a switchover request, a delay time or a delay crank angle is ascertained which is required for switching off or switching on again the intake or exhaust valve of one of the cylinders. Starting from the time or crank angle of the receipt of the switchover request and taking into account the ascertained delay time or the ascertained delay crank angle, the cylinder is selected whose at least one exhaust valve following the expiration of the delay time or of the delay crank angle starting from the time or crank angle of the receipt of the switchover request is the next to open in the switched-on state or would be the next to open, though it is switched off. This cylinder is ascertained as the one whose at least one intake or exhaust valve is designated to be the first to be switched off or switched on again following the receipt of the switchover request.

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 an internal combustion engine are provided which make it possible to implement different deceleration requests to the internal combustion engine by switching over between half engine operation and full engine operation. A deceleration request is received particularly in a nonoperating state. A switchover is made between a first operating state and a second operating state of the internal combustion engine as a function of the magnitude of the deceleration request. The first operating state and the second operating state differ, in this instance, in the number of cylinders whose charge changing process is interrupted.

摘要： A method and a device for operating an internal combustion engine make it possible to shift the combustion limit. In this context, a predefined output variable of the internal combustion engine such as the torque, for example, is realized in at least one operating state of the internal combustion engine by at least a retardation of an ignition angle. It is checked whether, due to the retardation of the ignition angle, a variable like, for example, a misfiring, characteristic for the combustibility of the air/fuel mixture in a combustion chamber of the internal combustion engine, exceeds a predefined limiting value in terms of a deterioration of the combustibility, and in this case, at least one actuator of the internal combustion engine, different from an actuator for setting the ignition angle, such as the exhaust-gas recirculation valve or EGR valve, for instance, is controlled along the lines of improving the combustibility of the air/fuel mixture.
