  • Method for improving the running smoothness of an internal combustion engine, control device and internal combustion engine
    Patent number: 7991541
    Abstract: In a method for improving the running smoothness of an internal combustion engine (1) which has at least one combustion chamber and at least one controllable actuator whose position has an influence on the combustion in the at least one combustion chamber, an irregular running value (f) of the internal combustion engine (1) is determined and compared with a predefined first irregular running limit value (f1thres), and in the event of the irregular running value (f) exceeding a predefined first irregular running limit value (f1thres), the actuator is moved from a starting position into an end position while the combustion in all of the combustion chambers of the internal combustion engine (1) is continued.
