Definitions

  • the invention relates to a method for cylinder detection for internal combustion engines according to the preamble of the main claim. It is already known from DE-OS 34 31 232 to provide two sensor wheels for cylinder detection, ie for detecting the compression in a cylinder, for example cylinder of the engine during a working cycle, of which the first sensor wheel with crankshaft speed and the second sensor wheel with half the crankshaft speed, i.e. at the speed of the camshaft.
  • a synchronization of the signals that are generated in the sensors assigned to the sensor wheels enables the clock to be recognized precisely, since the engine is located during the combustion cycle.
  • the failure of the sensor for detecting the camshaft revolution means that an exact position of the piston of a cylinder during a combustion cycle can no longer be recognized due to the missing phase signal.
  • the method according to the invention with the characterizing features of the independent claims has the advantage that a cylinder detection is possible even without a phase signal. Another advantage is that cylinder-specific controls, such as cylinder-selective injection or cylinder-selective knock control, can also be continued in the event of a phase sensor error. Ultimately, it is advantageous that safety measures for emergency operation, such as later ignition angle and mixture enrichment, can be omitted or can be terminated again after a short time.
  • FIG. 1 shows the relationship between camshaft and crankshaft signals on the basis of signal profiles
  • FIG. 2 shows a structogram for carrying out the method according to claim 1
  • FIG. 3 shows a structogram for carrying out the method according to claim 3.
  • the signal curves from the camshaft sensor NW and from the crankshaft sensor KW in a multi-cylinder internal combustion engine, as detected by a control unit and normal operating conditions, are shown as the first and second signal curves.
  • 1 shows the ignition control signal 1 output by the control unit on a first cylinder ZI. All three waveforms NW, KW and the ignition control signal 1 are shown via the crankshaft angle, with the range from 0 ° to 720 ° (i.e.
  • crankshaft revolutions (to be explained in more detail) in particular) .
  • the crankshaft of a four-stroke internal combustion engine rotates during one Combustion cycle twice around its own axis, thus the piston moves twice towards top dead center, once in the compression stroke and secondly in the exhaust stroke.
  • the crankshaft is usually connected to a sensor wheel, which for example consists of 60-2 teeth, in order to detect a complete crankshaft revolution.
  • the camshaft of an internal combustion engine rotates at half Crankshaft speed so that on two crankshaft revolutions one camshaft revolution is completed.
  • FIG. 2 shows a first embodiment of the inventive method of cylinder detection in idle mode.
  • the signals supplied by the sensors assigned to the sensor wheels, such as the camshaft signal NW and the crankshaft signal KW, are detected.
  • a subsequent query 6 checks whether the phase signal of the camshaft NW was in order.
  • safety measures M1, M2 and M3 include, for example, the output of safety ignition angles for knock control, the mixture enrichment and the output of dual ignition, ie an ignition pulse is triggered before each top dead center is reached.
  • a work step 9 it is ensured, by detecting the corresponding operating parameters of the internal combustion engine, that the internal combustion engine is operating in a virtually stationary state.
  • fixed values for the air pilot control and for the ignition angle are output for the steady state of the idle mode of the internal combustion engine in such a way that the idle speed increases slightly. This is necessary in order to avoid the engine stopping when a load is switched on, eg air conditioning.
  • the ignition angle is output so that a change in the ignition angle will have an immediate effect on a change in speed.
  • the ignition angle of one of the two ignitions per combustion cycle that is, a double ignition on the cylinder 1, is changed by changing it in the early or late direction.
  • An uneven running evaluation is then carried out in a query 12 and checks whether a speed change occured.
  • a yes in the query 12 ie a speed change n was determined on the basis of a change in the ignition angle in the early or late direction, leads to a work step 13.
  • a speed change n was determined on the basis of a change in the ignition angle in the early or late direction, leads to a work step 13.
  • the ignition can thus be assigned to the cylinder 1 and in a work step 14 the safety measures initiated for an emergency operation mode M1, M2 and M3 are deleted again.
  • step 12 a no in query 12, ie no speed change could be determined, leads to the control unit recognizing that the ignition output occurred with the ignition angle change in the charge change cycle (exhaust cycle), so that the ignition angle change without Consequence for the speed had to remain.
  • Step 16 the safety measures for emergency operation are deleted. Steps 14 and 16 result in a step 17 in which it is checked again whether the phase signal was OK. When transitioning from idling LL to part-load range, the corresponding gap is used as the cylinder assignment, otherwise no additional measures are carried out.
  • FIG. 3 is to explain a second exemplary embodiment of the cylinder assignment for idling operation of an internal combustion engine in the event of a missing or faulty phase signal.
  • the beginning of this process is identical to the process described in FIG. 2, so that work steps 5 to 11 will not be explained again.
  • a step 18 After changing the ignition angle of every second ignition per crankshaft revolution in step 11, it is checked in a step 18 whether the change in ignition angle has counteracted the air pilot value for the idle speed. If this is not the case, that is to say a no to query 18, the changed ignition is assigned to the charge cycle in a subsequent work step 19. In step 20, the ignition signal for the subsequent ignition is thus shifted by 360 ° to the previously changed ignition.
  • the safety measures for emergency operation can be deleted in work step 21.
  • the security measures M1, M2 and M3 can be deleted.
  • the work steps 21 and 23 of this method are connected to a work step 24.
  • the ignition or injection is now controlled by the control unit with the determined cylinder assignment until the next control unit reset.
  • the process then begins again by jumping to the start of the process in step 24.

Abstract

On propose un procédé permettant d'identifier un cylindre dans des moteurs à combustion interne au ralenti dans le cas d'un signal de phase manquant ou défectueux. A cet effet, une étincelle d'allumage est produite dans chaque cylindre par chaque vilebrequin et l'angle d'allumage prédéterminé du ralenti est modifié pendant au moins un allumage d'un cylindre pour une rotation du vilebrequin sur deux. Ensuite, la réaction à la modification de l'angle d'allumage dans le sens d'une avance ou d'un retard est déterminée par la détection d'une irrégularité de fonctionnement ou par le contrôle de la valeur de commande de l'air et l'affectation d'un cylindre est déterminée en conséquence.
