Definitions
- a method for cylinder equalization in which maximum cylinder pressures in a single cylinder are determined by means of ion current measurement and average values of the maximum pressures are formed, wherein at least one cylinder is identified in dependence of a comparison between cylinder groups its operating behavior is to influence.
- the internal combustion engine has, for example, one or more of the following measures until at least one abort criterion, i. in practice only for a short time to be set:
- the routine starts with the nominal settings of a normal operating mode of the internal combustion engine, preferably at full engine speed, since there the ignition pressure is highest and the internal combustion engine is running close to the knock limit.
- a normal operating mode of the internal combustion engine preferably at full engine speed, since there the ignition pressure is highest and the internal combustion engine is running close to the knock limit.
- start routine 20 bar with p me as medium pressure (break mean effective pressure, BMEP)
- the combustion air ratio lambda is set to 0, 01 steps reduced. Reducing the combustion air ratio lambda means enrichment of the mixture.
- a specific cumulative ignition timing adjustment has been achieved. So be For example, with three piston-cylinder units, the ignition timing adjusted by 4 ° KW, this results in a cumulative ignition timing of 12 ° KW.
- This abort criterion can be combined, for example, in combination with a reduction of the lambda value by a certain amount, for example 0.05.
- the method is limited to one selection, i.
- the detection mode could initially be performed only for a part of the piston-cylinder units or even only a piston-cylinder unit and after completion of the routine another detection mode or detection modes for start the remaining piston-cylinder units.
- FIG. 3 shows a diagram of cylinder tip pressures of an internal combustion engine according to FIG.
- the ignition timing of a piston-cylinder unit 2 can be determined by a corresponding control of the ignition device 5 by the control / regulating device 4.
- the piston-cylinder units 2 also have a sensor device 3, via which knocking of the relevant piston-cylinder unit 2 can be detected.
- the sensor device 3 may be formed, for example, as a structure-borne sound sensor. The signals detected by the sensor device 3 can be reported to the control / regulating device 4.
- the termination criterion can be, for example, whether a certain number of piston-cylinder units 2 are already knocking.
- the illustrated flowchart shows an embodiment of the inventive method.
- it is not permitted that several piston-cylinder units 2 knock at the same time, but the ignition timing of the relevant piston-cylinder unit 2 is retarded immediately after the detection of knocking.
- the routine it may nevertheless be provided that it is noted which piston-cylinder unit 2 was knocking and for which the ignition point has already been adjusted.
- FIG. 3 shows a graph of the cylinder tip pressures of individual piston-cylinder units 2 of an internal combustion engine 1 in percent over time. In this illustration, the values are averaged over a number of combustion cycles.
- the right side of the diagram shows the situation after carrying out the method according to the invention on the internal combustion engine.
- the effective mean pressure P me is in this example, even after passing through the method for Klopfredumie unchanged at 20 bar.
- the mean value of the ignition times is now 19.7 ° CA before top dead center, ie a little later than before going through the process.
