Two reference marks 13, 14 are marked by two missing angle marks were formed. They lie to each other on the encoder disc opposite.
the length L1 of the Angle marks is in the correct ratio, e.g. B. to the pole core of the associated transducer.
a second encoder disk 15 is connected to the camshaft 16 Internal combustion engine connected and points to its scope Segment angle marks 17 on, with a length L3.
segment angle marks 17a, 17b, 17c, 17d are further synchronization angle marks 18a, 18b, 18c present, one of each Synchronization angle marks of a segment angle mark is assigned and the distances between the segment angle marks and the synchronization angle marks are of different lengths.
One of the segment angle marks is in the embodiment of the segment angle mark 17d no synchronization angle mark assigned.
the camshaft 16 of the internal combustion engine is operated by the Crankshaft 10 driven and rotated in the usual way at half the speed of the crankshaft 10.
the rigid connection between crankshaft 10 and camshaft 16 is symbolized by line 19.
the encoder disks run the angle marks past sensors 20 and 21. In the transducers this creates tensions that affect the surface of the Play encoder disks.
the encoder disk 11 and the Pickups 20 are also used as crankshaft sensors and Sensor disc 15 with the sensor 21 as a camshaft sensor designated.
Inductive sensors, Hall sensors, capacitive transducers or with a corresponding adjustment also use optical sensors, these optical Sensors then consist of a transmitter and a receiver and there are angular marks between these two elements move.
the direction of rotation of the shafts or disks is each indicated by an arrow.
the signals of the Pickups 20 and 21 are designated S1 and S2. she are fed to a control unit 22, in which at least a computing device, for example a microprocessor including the associated memory. in the Control unit, the signal curves are evaluated.
an EDC control unit run for the regulation of the internal combustion engine required Calculations based on the data from the sensors 20, 21 delivered signals S1 and S2.
the control unit further information supplied by corresponding Sensors are supplied and via corresponding inputs E1 be fed.
the control unit outputs A1, for example Injection pulses to the injectors 24.
the Power is supplied via the switch 25 through the Battery 26.
each cylinder of the internal combustion engine Segment angle mark on the assigned to the camshaft 16 Assigned encoder disc 15.
Get three of the four cylinders additionally one in one for the cylinder characteristic distance to the segment angle mark arranged synchronization angle mark.
At one of the No synchronization angle mark is placed on the cylinder, but only a segment angle mark.
the position of the encoder disks relative to each other can be Synchronization angle mark a certain Crankshaft encoder disc angle mark 12 can be assigned. This is a clear cylinder detection and thus synchronization of the crankshaft encoder disk possible.
FIGS. 2 and 3 specified signal profiles, or relationships between Signals and encoder disc surface.
Figure 2 is based the example of the camshaft segment of cylinder 2 shows how the signals are generated.
the surface of the encoder disk 15 in Figure 2a Area of the segment mark 17c, or the synchronization angle mark 18c shown.
the distance between the Segment angle mark 17b and the synchronization angle mark 18b is 18 ° NW (i.e. related to the camshaft).
the Direction of rotation is symbolized by an arrow.
FIG 2b is the associated signal curve S2, which the pickup 21 delivers, represented. From this waveform the Figure 2c shown square wave signal that ultimately to Synchronization is used, formed.
the surface of the encoder disk 11 is shown in FIG. 2d with the angle marks 12 and the reference mark 14.
the signal S1 is generated that in Figure 2e is specified.
This signal S1 becomes the rectangular one Signal that is shown in Figure 2f formed.
the education of square wave signals from sinusoidal signals takes place in generally known manner. For example, in a the evaluation circuit assigned to the transducer or in Control unit 22 take place.
FIG. 3 the processed signals are above Crankshaft angle plotted, the crankshaft angle is given in degrees OT.
Figure 3a that is from the Scanning the multitude of angle marks on the So-called crankshaft encoder disk obtained Incremental signal that occurs when using a crankshaft encoder disc 11 according to FIG. 1 results. This Increment signal is at the input of the control unit integrated angle clock.
Figure 3b is the processed Camshaft sensor signal, which at the input of the computer of the Control unit 22 is present for the various Areas of the camshaft sensor disk assigned to respective cylinders shown.
FIG. 3c shows in which crankshaft angle tolerance range the camshaft sensor signals may occur so that they are still clear can be assigned.
the reference mark lies due to boundary conditions 1 and 4 between the preferred position of the internal combustion engine and the the next but one ignition TDC.
the maximum Total tolerance of the position of the camshaft pulses to the Crankshaft pulses should be less than +/- 9 ° KW.
This Total tolerance is made up of the Manufacturing tolerances of the angle marks and the Mounting tolerances of the two encoder disks from which Angle of rotation between crankshaft 10 and camshaft 16 and from inaccuracies in the signal acquisition and from the Processing time of the computer.
FIG. 4 shows the sequence of the camshaft sensor signals.
FIG. 5 shows those already shown with reference to FIG. 2 Encoder disk configurations, or signals via a shown larger crankshaft angle range.
the associated system of a quick start encoder disk configuration for one Four-cylinder internal combustion engine is through synchronization angle marks able on the camshaft encoder disc quickly recognize the current cylinder. This is through Querying the position of the synchronization angle mark to be checked realized in the cylinder segment. Will a location identified from several possible, then this location, defined by an upper and a lower limit, in Data record that is stored in the computer of the control unit Assigned cylinder. If a cylinder is identified, it runs then a cylinder counter.
This cylinder counter is running in a four-cylinder internal combustion engine from zero to three. In general, Z cylinders are counted up to Z-1. By checking the correctness of this process can be further information regarding the functionality of the System. To determine whether the process is correct is, the position of the Synchronization angle marks checked. The determined Meter reading indicates a specific location of the Synchronization angle mark, which is stored in the data record is. If the angle mark that occurs has this target position, classified them as plausible. Is it in a position other than that determined by the cylinder counter and with a lower and upper limit position defined in the data set, the relevant synchronization angle mark is used as classified incorrectly and possibly a malfunction of the system recognized and displayed.
crankshaft encoder disk the camshaft sensor disk and the associated waveforms for a 3 cylinder Internal combustion engine specified.
the one with the crankshaft connected encoder disc has a reference mark for every cylinder.
