Definitions
- the invention relates to a device Phase detection in an internal combustion engine after Genus of the main claim.
- a multi-cylinder internal combustion engine with a crank and at least one camshaft is in the control unit Depends on the recognized position of the crank and the Camshaft calculates when for which cylinder fuel to be injected and when an ignition is triggered shall be. It is common for the angular position of the Determine crankshaft with the help of a sensor that the Crankshaft or a disk connected to it scans a characteristic surface.
- a system at which the phase position is determined without a phase sensor is from DE-OS 44 18 577 known.
- the start of the injection is obtained from the Angular position of the crankshaft for the individual cylinders, also pre-storage angle called, specifically changed so that from one work cycle to the next at wrong Phase position a speed change is initiated, which is evaluated with the help of the Crankshaft sensor delivered signals is detected.
- This speed change is in Control unit recognized and evaluated and for phase detection and then on used for phase synchronization.
- a method for phase detection is already known from EP 640 762 A1 the presence or absence of a change in speed when fading out Injection processes is evaluated. This procedure only takes place with a static one Operation of the internal combustion engine.
- the inventive device for phase detection with the features of Claim 1 has the advantage that a particularly fast synchronization without Camshaft sensor can be done.
- FIG. 1 In the control system for an internal combustion engine shown in FIG denotes an encoder disk, which is rigid with the crankshaft 11 of the internal combustion engine is connected and on its circumference a multiplicity of similar angle marks 12 having.
- a reference mark 13 In addition to these similar angle marks 12 there is a reference mark 13 available, which is realized 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 Output signals to the control unit 15 delivers the after signal processing are available as square-wave signals that reflect the surface of the encoder disk 10.
- Phase sensor that the camshaft 16 or one with the Camshaft 16 connected disc with a mark is not provided here.
- the information with respect to the phase position, which from the output signal of a Such a sensor is usually obtained here Get help using the procedure described below.
- the control unit 15 receives via various inputs further, for the control or regulation of the Internal combustion engine required input quantities.
- the associated sensors are designated 17. About one further input, an "ignition on” signal is fed, the one connecting the ignition switch 18 from the terminal Terminal 15 of the ignition lock is supplied.
- the at least one central processor unit 18 and one Memory 19 includes signals for the ignition and Injection determined, these signals are on the Outputs 20 and 21 issued.
- the power supply of the Control unit 15 is carried out 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 during operation of the Internal combustion engine can be detected at any time. Since the Assignment between crankshaft and camshaft as well is known how the assignment between the position of the Camshaft and the position of the individual cylinders, can according to synchronization takes place when the reference mark is recognized, however, only if one for the phase position characteristic signal is present.
- the phase signal is required because the one supplied by the crankshaft sensor Reference mark signal is ambiguous because the crankshaft within one working cycle of the internal combustion engine two Turns while the camshaft turns only once.
- phase angle in a system without a phase sensor can be recognized and a sequential injection the following functions run in the control unit:
- the adjusting signals of the crankshaft sensor evaluated. If the reference mark is recognized for the first time, the sequential injection at the first reference mark started. Since it is unclear in which revolution the Crankshaft is the lead angle for the Injection either correct or wrong by 360 ° KW. to Phase recognition will be injections after the start hidden or suppressed for a cylinder. This Injection is suppressed approximately three times Working games in the falling branch of the start overshoot. With the branch of the take-off overshoot falling off Speed drop meant that in Figure 2 or Figure 4 with area 1 is marked. Can't phase the blanking will be clearly determined at idle repeated after a short wait.
- segment times are monitored.
- the Segment times are defined so that they are approximately lie symmetrically around the ignition TDC of the respective cylinder and the segment location must be specified for each engine become.
- the segment length is 720 ° KW / number of cylinders and includes a certain number of angle marks or
- a dynamic value can be calculated which must exceed a predeterminable absolute value so that a misfire is detected on the corresponding cylinder.
- the difference between the last two dynamic values can also be calculated.
- 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 was 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. 2 and 3 are: open the inlet valve, Injection pulse, ignition, fading out, re-synchronization and Speed versus time for an example where the Injection by 360 ° KW was wrong and a re-synchronization was required.
- Figures 4 and 5 is the same thing for an example with correct Synchronization applied.
