Definitions
- the invention relates to a method for determining a cylinder pressure crankshaft position assignment for an internal combustion engine.
- the invention is based on the object to provide a novel method for determining a cylinder pressure crankshaft position assignment for an internal combustion engine.
- This object is achieved by a method for determining a cylinder pressure crankshaft position assignment for an internal combustion engine according to claim 1.
- the method comprises the following steps: metrological detection of the crankshaft angle; metrological detection of the cylinder pressure; Calculating a cylinder volume dependent on the crankshaft angle; Determination of a curve for the logarithmic cylinder pressure over the logarithmic cylinder volume as a function of the crankshaft angle; Analyzing the curve and determining an offset value for the crankshaft angle to determine a time-accurate cylinder pressure crankshaft position mapping.
- the inventive method allows automatic determination of cylinder pressure crankshaft position assignment for cylinders of an internal combustion engine with simple means and high accuracy.
- the method according to the invention can be carried out automatically in internal combustion engines, both in fired operation and in non-fired, towed operation of an internal combustion engine.
- the crankshaft angle and the cylinder pressure are detected metrologically.
- the cylinder volume is calculated from the crankshaft angle, wherein a curve for the logarithmic cylinder pressure over the logarithmic cylinder volume as a function of the crankshaft angle is determined from the calculated cylinder volume, the measured crankshaft angle and the measured cylinder pressure.
- This curve is analyzed and, depending on the analysis, an offset value for the crankshaft angle for determining the chronologically accurate cylinder pressure crankshaft position assignment is determined.
- the curve is analyzed in the region of a cylinder inversion point for determining the offset value.
- the curve can be analyzed in the region of a lower cylinder inversion point or in the region of an upper cylinder inversion point for determining the offset value.
- the analysis of the curve in the area of the cylinder inversion point is particularly advantageous.
- FIG. 1 shows a curve for determining an offset value for the crankshaft angle for determining a chronologically exact cylinder pressure crankshaft position assignment
- FIGS. 2a to 2c show alternative details of the curve of FIG. 1.
- the present invention relates to a method for automatically determining a cylinder pressure crankshaft position assignment for the cylinders of an internal combustion engine.
- the inventive method is automatically carried out both in the fired operation of an internal combustion engine as well as non-fired, towed operation of an internal combustion engine.
- a crankshaft angle is continuously measured by means of a rotary encoder, for example. Furthermore, the cylinder pressure is automatically detected with the aid of a pressure sensor, in particular depending on the crankshaft angle. From the metrologically detected crankshaft angle, the cylinder volume of the respective cylinder of the internal combustion engine is determined.
- a curve is determined for the logarithmic cylinder pressure over the logarithmic cylinder volume as a function of the crankshaft angle. This curve is analyzed, wherein from the curve an offset value for the crankshaft angle for determining the exact timing cylinder pressure crankshaft position assignment is determined.
- the analysis of the curve preferably takes place in the region of a cylinder inversion point, namely either in the area of the lower cylinder inversion point or bottom dead center or in the region of the upper cylinder inversion point or top dead center of a cylinder piston movement the respective cylinder of the internal combustion engine.
- FIG. 1 shows in a highly schematic manner a curve for the logarithmic cylinder pressure log p over the logarithmic cylinder volume log V as a function of the crankshaft angle, wherein in FIG. 1 the logarithmic cylinder pressure log p is greater than the logarithmic cylinder volume log V for two full revolutions the crankshaft is applied, so over 720 ° of the crankshaft angle.
- the diagram of Figure 1 therefore includes the combustion process and a charge change in the respective cylinder of the internal combustion engine.
- Figures 2a, 2b and 2c show different, alternative details of the diagram of Figure 1 in the region of the lower reversal point and bottom dead center of the cylinder piston movement of the respective cylinder. In the region of the lower point of reversal or bottom dead center of the cylinder piston movement of the respective cylinder, the curve of FIG. 1 or of FIGS. 2 a, 2 b and 2 c is formed by curved segments 1 1 and
- the curve in the region of this reversal point 13 is analyzed, namely in such a way that when in the region of the cylinder inversion point
- an area between the curve segments 1 1 and 12 of the curve in the region of the reversal point 13 is determined, wherein the offset value is determined depending on the area to compensate for the detected time shift between the cylinder pressure signal and the crankshaft angle signal.
- the offset value is determined iteratively such that the area between the curve segments 1 1 and 12 of the curve in the region of the cylinder inversion point is minimal. This is the case, for example, in the diagram of FIG. 2a.
- the entire process can be performed continuously and automatically during the fired or towed operation of an internal combustion engine. In this way, an exact time assignment of the cylinder pressure to the crankshaft angle can be determined fully automatically during operation in order to control or regulate the operation of the internal combustion engine depending on this.
