Definitions
- the invention relates to a device for phase detection in an internal combustion engine according to the preamble of the main claim.
- the control unit calculates, depending on the detected position of the crankshaft and the camshaft, when fuel should be injected for which cylinder and when an ignition should be triggered. It is customary to determine the angular position of the crankshaft with the aid of a sensor which scans the crankshaft or a disk connected to it with a characteristic surface.
- crankshaft rotates twice within one working cycle of the internal combustion engine, the phase of the internal combustion engine cannot be clearly determined simply by scanning the crankshaft. So that this is possible, a sensor disc, which is connected to the camshaft and has a reference mark on its surface, is usually scanned with the aid of a second sensor. There If the camshaft only rotates once during a work cycle, the control unit can be identified from the combination of the signals supplied by the crankshaft and camshaft sensors, and the so-called synchronization can be carried out.
- the inventive device for phase detection with the features of claim 1 has the advantage that synchronization can take place without a camshaft sensor, that no additional components are required and that
- Phase detection can run reliably and without interference, and if the wrong phase position is detected, a correction or resynchronization can be carried out.
- FIG. 1 the components of a control system of an internal combustion engine required to explain the invention are shown schematically and in FIGS. 2 to 5, quantities or control signals essential to the invention are plotted against time.
- the internal combustion engine is designated by 10, an encoder disc, which is rigidly connected to the crankshaft 11 of the internal combustion engine and has a plurality of similar angle marks 12 on its circumference. In addition to these similar angle marks 12, there is a reference mark 13, which is implemented, for example, by two missing angle marks. The total number of angle marks is, for example, 60-2.
- the sensor disk 10 is scanned by a sensor 14 which supplies the control unit 15 with output signals which, after signal conditioning, are present as square-wave signals which reflect the surface of the sensor disk 10.
- phase sensor which is present in conventional internal combustion engines and which scans the camshaft 16 or a disk connected to the camshaft 16 with a marking is not provided here.
- the control unit 15 receives further inputs for the control or regulation of the
- the associated sensors are designated 17. Via a further input, an "ignition on” signal is supplied, which supplies the ignition switch 18 with a connection from the terminal 15 of the ignition lock.
- the control unit 15 which comprises at least one central processor unit 18 and a memory 19, signals for the ignition and injection are determined, these signals are emitted via the outputs 20 and 21.
- the voltage supply to the control unit 15 takes place in the usual way with the aid of a battery 22 which is switched on via a switch 23.
- the position of the crankshaft 11 can be detected at any time during operation of the internal combustion engine. Since the
- phase position can be recognized and a sequential injection can take place in a system without a phase sensor:
- the signals from the crankshaft sensor are evaluated. If the reference mark is recognized for the first time, the sequential injection is started at the first reference mark. Since it is unclear in which revolution the crankshaft is, the advance angle for the injection is either correct or wrong by 360 ° KW. For phase detection, injections for a cylinder are hidden or suppressed after the start. This suppression of the injection takes place approximately three
- the falling branch of the start overshoot means the drop in speed, which is marked with the area 1 in FIG. 2 or FIG. 4. If the phase position cannot be clearly determined, the blanking is repeated after a short wait in idle.
- Segment times are defined so that they are approximately symmetrical around the ignition TDC of the respective cylinder and the segment position must be specified for each engine.
- the segment length is 720 ° KW / number of cylinders and includes a certain number of angle marks or Signal edges. Since the time in which the crankshaft rotates around a segment is determined, the speed evaluation results in a low-pass behavior. Averaging takes place over several angle marks or angle marks.
- the position of the segment is to be chosen so that the segment time increase due to a hidden cylinder, i.e. the time increase caused by selective combustion, is half in the segment. This results in the greatest possible signal-to-noise ratio to the next segment.
- Speed range takes place.
- the number of suppressed injections -1 on a cylinder for example, must have been recognized.
- a phase search can be successfully completed if the resulting drop in speed has been correctly recognized twice with three fades out. In a further condition, it may be required that no misfires have been detected on another cylinder. If the phase search reveals that the synchronization by 360 ° KW is wrong, a re-synchronization is carried out.
- FIGS. 4 and 5 show the same facts for an example with correct synchronization.
