Abstract
A method for adapting a preset value for a minimum valve stroke in an internal combustion engine, has the following steps: Replace the previous value for the minimum valve stroke with a new value; Determine an operating parameter of the internal combustion engine; Restore the previous value for the minimum valve stroke if the operating parameter is outside of a defined value range; otherwise retain the new value.
Claims18
A method for adapting a preset value for a minimum valve stroke in an internal combustion engine, comprising the following steps:
- Replacing the previous value for the minimum valve stroke with a new value;
- Determining an operating parameter of the internal combustion engine;
- Restoring the previous value for the minimum valve stroke if the operating parameter is outside of a defined value range and otherwise retaining the new value.
A control device comprising a memory device that is operable to control a valve stroke in an internal combustion engine, wherein the control device holds a value for a minimum valve stroke in the memory device, and wherein the control device is further operable to change the value for the minimum valve stroke.
A device for adapting a preset value for a minimum valve stroke in an internal combustion engine, comprising:
- means for replacing the previous value for the minimum valve stroke with a new value;
- means for determining an operating parameter of the internal combustion engine;
- means for restoring the previous value for the minimum valve stroke if the operating parameter is outside of a defined value range and otherwise for retaining the new value.
