Definitions
- the invention relates to a method for controlling the combustion in the combustion chamber of an internal combustion engine, as is already known from DE 43 41 796 AI. In this known method is in each combustion chamber
- Internal combustion engine arranged a pressure sensor so that the pressure in the combustion chamber can be detected in a predetermined period.
- the pressure values during the compression stroke are stored until a predeterminable crank angle is reached and, after passing through the predeterminable crank angle, are output in mirror image in the same time periods, so that the difference between the pressure values still recorded during combustion and the output pressure values during the compression stroke can be formed .
- the integral of the determined difference and the associated crank angle, at which a predeterminable area share of the integral is reached, forms the basis for determining the deviation of a determined crank angle from a predefined target crank angle, so that the combustion position is regulated on the basis of the determined deviation in the control unit can.
- Methods are also known, in which detonator detections of the respective work cycle a pressure sensor in the Combustion chamber is arranged, and when a threshold value is exceeded by the sensor signals, it is decided that the cylinder in question is in its combustion cycle. Furthermore, it is known to provide a knock sensor for recognizing the respective work cycle, the signal of which is also compared with a threshold value and, if the threshold value is exceeded, it is concluded that the cylinder in question is in its work cycle.
- the method according to the invention with the features of the main claim has the advantage over the known that no pressure sensor is to be provided in the combustion chamber, as a result of which additional bores in the cylinder head can be avoided. Furthermore, by reconstructing the combustion chamber pressure curve from the signal of the knock sensor, various operating variables of the internal combustion engine can be detected without additional sensors. With this method, the sensors that are already present can therefore be used to control various parameters.
- FIG. 1 shows the basic structure of an evaluation unit with control unit for internal combustion engines and
- FIG. 2 shows the basic method steps for processing the signals of the knock sensors.
- FIG. 1 shows the schematic structure of an ignition system with knock sensors and evaluation unit.
- four knock sensors 11 to 12 are each assigned to a single cylinder, not shown here.
- the knock signal KS detected by each knock sensor 11 to 14 is fed to a downstream evaluation unit 15.
- the evaluation unit 15 is also supplied with the crankshaft signal KW.
- the cylinder-specific knock sensor signal is now conditioned in the evaluation unit 15 by means of corresponding evaluation methods, and the combustion chamber pressure curve of these cylinders is thus reconstructed from the measured acoustic signal.
- the combustion position as is already known from DE 43 41 796 AI, is then determined from the reconstructed combustion chamber pressure curve.
- the phase position as already described in detail in DE 40 02 228 AI, can be determined on the basis of the reconstructed combustion chamber curve and by comparison with a threshold value.
- control variables 16 are then output as control variables 16 to a control unit 17, see above that the various control variables, for example for the ignition, are determined in the control unit 17 on the basis of the supplied control variables 16 and further input variables 18, which are determined by sensors not shown here.
- FIG. 2 shows an overview of the individual process steps.
- the knock signal KS is detected individually for the cylinder and, on the one hand, is passed on to step 21, in which the combustion chamber pressure curve for this cylinder is reconstructed from the knock signal KS.
- the knock signal is examined in a step 22 for knocking KL that may have occurred during combustion.
- an evaluation can then be carried out in various work steps assigned in parallel, either optionally for one or for all work steps.
- the phase signal is determined in a step 23, the uneven running in a step 24, combustion misfires in a step 25 and the combustion situation in a step 26.
- the outputs of these work steps 23 to 26 and the output of the knock detection circuit 22 are then guided to a work step 27 for controlling and regulating the subsequent combustion.
