Definitions
- the invention relates to a method for controlling the combustion position in an internal combustion engine having a plurality of cylinders, in particular a diesel internal combustion engine, wherein at least one engine operating parameter is detected.
- DE 10 2006 001 374 A1 describes a device and a method for controlling and / or regulating an internal combustion engine, in particular a direct-injection internal combustion engine.
- a control regulates a combustion position variable characterizing the combustion position to a desired value.
- a control and / or a regulation influences a moment variable characterizing the moment of the internal combustion engine and / or a noise quantity characterizing the noise of the internal combustion engine by means of a control variable.
- the structure of the control of the combustion position but not the calculation of the necessary input signals for the control is described.
- AT 503.061 A1 discloses a method for controlling combustion, in particular in diesel internal combustion engines, wherein the pressure is measured in at least one cylinder.
- the cylinder pressure and the combustion position is calculated according to the firing order only in every second cylinder, and that the combustion position of the following cycle in this cylinder due to the determined cylinder pressure, or Combustion is controlled so that the actual cylinder pressure, or the actual combustion position is adjusted to a target value for the cylinder pressure, or the combustion position.
- the cylinder pressure or the combustion position is determined from the measured cylinder pressures, in particular from an average value of the measured cylinder pressures in the cylinders adjacent to one another in the ignition sequence.
- a method for regulating the characteristic values of the combustion in an internal combustion engine wherein a fast control path, which can act and measure with each injection, takes into account a slow control path, which requires a much longer time in a time grid than the fast control path, and the magnitude of the deviation between the actual values and the set values of the slow control path Effects on combustion parameters and / or changes of at least one characteristic of the fast control path can be calculated.
- the object of the invention is to allow the simplest possible and cost-effective way a precise combustion position control.
- this is achieved by providing an arithmetic or characteristic-based cylinder-selective combustion position model, which establishes a relationship between at least one determined engine operating parameter and the combustion position, and determining the combustion position for each cylinder on the basis of the determined engine operating parameter by means of the combustion position model.
- a preferably cylinder-selective combustion control signal particularly preferably selected from the group injection timing, distances to pre and post injections, injection quantity, injection pressure, injection duration or the like is used as the engine operating parameter.
- a sensor signal of the engine sensors preferably selected from the group speed, intake air mass, boost pressure, charging temperature, coolant temperature, fuel pressure, lambda probe value is used as engine operating parameters.
- the cylinder-selective combustion layer model calculates a cylinder-selective "virtual" sensor value of the combustion position for each cylinder. This is used to control the combustion position.
- the combustion layer model is based on a calculation based on signals available in the engine control. On the one hand, these are sensor signals from the standard engine sensor system, such as, for example, speed, intake air mass, charge pressure, charge temperature, coolant temperature, fuel pressure, ⁇ probe value, or the like. On the other hand, control signals are used which influence the combustion, such as injection timing, time intervals between the main injection and the pre-injection or Nacheinspritzereignisse, injection quantity, injection pressure or the like.
- the cycle gauge pressure is measured and from the cylinder pressure signal, a reference combustion position is determined, and that due to the difference between the determined from the cylinder pressure of the reference cylinder reference combustion position of the reference cylinder and the modeled combustion position of the combustion position model of the reference cylinder, a model error is calculated, and that the combustion position model by the preferably filtered model error is corrected.
- the actual combustion layer 6 is determined via a cylinder pressure sensor and fed to the combustion position controller 1 as an actual value.
- a cylinder pressure sensor is required for each cylinder. If mean values of signals from adjacent cylinders are used, the number of required cylinder pressure sensors can indeed be reduced, but this is done at the expense of the control quality.
- Fig. 2 shows a combustion position control according to the invention.
- the combustion position controller 11 performs an engagement 13 in the combustion position at a particular cylinder x due to a desired combustion position 12, whereby combustion 14 takes place in the cylinder x.
- a combustion position model 15 for one or more cylinders x is now included in the combustion position control.
- the combustion layer model 15 receives as input variables various engine operating parameters, on the one hand sensor signals 16 from the standard sensor of the engine control and on the other hand control signals 17 from the engagement 13 in the combustion position, such as injection timing, injection quantity, intervals between pilot, main and post injection, injection pressure, injection duration or the like , On the basis of the signals 16, 17, the combustion layer model 15 determines a cylinder-specific fictitious combustion position 18.
- the fictitious combustion position can be supplied as information about the real combustion position of the combustion position control 11 as an actual value.
- the combustion position is determined by means of a cylinder pressure sensor in a reference cylinder.
- the reference combustion position is designated by reference numeral 19 in FIG.
- the reference combustion layer 19 is compared with a fictitious model-based combustion layer 20 determined by the combustion layer model.
- the fictitious combustion position 18 from the combustion position model 15 is correspondingly corrected on the basis of the detected model error 21, wherein the signal of the model error 21 is still due to a low-pass filter 22 is performed so that only the average model error 21 is corrected.
- the necessary number of cylinder pressure sensors can be significantly reduced without sacrificing the control quality, whereby a significant cost savings can be achieved.
