Definitions

  • the invention is based on a method for determination the phase position with a 4-stroke internal combustion engine odd number of cylinders according to the genus of the main claim.
  • crankshaft position using its own sensor one so-called phase sensor to determine
  • this Phase sensor with a disc connected to the camshaft scans a single marker.
  • the resulting signal which has one pulse per camshaft revolution also evaluated in the control unit.
  • crankshaft and camshaft By the one Internal combustion engine with an odd number of cylinders prevailing Conditions and the fixed phase relationship between The crankshaft and camshaft can be easily identified logical connection of the crankshaft signal and the second signal perform a work cycle detection, because the periodically fluctuating in one crankshaft revolution second signal must be "high” while it is in the other Revolution of the crankshaft must be “low”. With the known So the work cycle recognition is based on a simple logical combination of two signals.
  • US-A-4 266 427 describes a control system the injection in an internal combustion engine, in which the Cylinder pressure is measured using a sensor. To the results of the cylinder pressure, among other things, the sign reversal of the Gradient of the pressure curve evaluated. In addition, the Start of injection recognized or the injection process evaluated. This happens with the help of its own sensor that detects the movement of the Injector needle detected. By suitable preparation of the two sensor signals and by linking them Information obtained can be seen which cylinder is at top dead center.
  • DE-OS 42 29 773 describes a method for cylinder detection Internal combustion engines described, which also allows missing or faulty phase signal a cylinder detection perform. For this purpose, at predetermined times or at Predefinable crankshaft angle positions triggered and the reaction in the cylinder was evaluated. Depending on whether the If the ignition timing was selected correctly or incorrectly, the result is one Combustion or a misfire, so that the cylinder detection be performed.
  • the method according to the invention for determining the phase position in a 4-stroke internal combustion engine with the features of Claim 1 has the advantage that a motor synchronization is possible without detecting the camshaft position. This also applies to systems where there is a phase relationship is changeable between crankshaft and camshaft. achieved is this advantage according to the present claim 1, by the to determine the phase position signal provided by the crankshaft angle sensor, the one Has singularity, with a second signal, which in the Combustion cycle fluctuates and cylinder-specific Has peculiarities, is related, with the Determination of the phase position of the course of the second signal during the occurrence of the singularity of the first signal is examined.
  • the method for determination the phase position already during the starting process can be carried out before the first A cylinder is fired. This early It is possible to determine the phase position because the different cycles even without firing differently on the speed or the intake manifold pressure impact.
  • the sensor can including electronics, the camshaft sprocket and the corresponding Cabling can be saved. Can on the engine control unit three connector pins and the processing circuit for the Sensor and a computer port pin can be saved. The PCB area can also be reduced. Without Camshaft sensor can be based on its diagnosis and No error handling measures for this sensor be, which increases the availability of the overall system elevated. These savings can be achieved without this adversely affects the exhaust or starting behavior of the Engine affects. It proves to be advantageous also that the claimed methods are no additional Cause runtime load on the control unit software because synchronization before the actual engine operation is completed and therefore none for the computer resources Represents runtime restriction.
  • FIG 1 are those for explaining the invention required components of the control system one Internal combustion engine shown schematically.
  • a sender disk that is rigid with the crankshaft 11 of the internal combustion engine is connected and on its circumference has a plurality of similar angle marks 12.
  • this similar angle mark 12 is a reference mark 13 available, for example by two missing Angle marks is realized.
  • the encoder disk 10 is supported by a sensor 14, for example an inductive sensor or a Hall sensor sampled.
  • an internal combustion engine has usually also at least one camshaft that is designated in Figure 1 with 25 and usually with the Crankshaft 11 is in a fixed reference. This reference is symbolized by line 16.
  • the angular position of the Camshaft 15 is shown in the figure 1
  • Control system of an internal combustion engine is not detected.
  • This second signal S2 is generated using a sensor 17 won.
  • the sensor 17 is a sensor that the pressure in Intake pipe of the internal combustion engine measures.
  • the control unit 15 can be further, for the control or Regulation of the internal combustion engine required input variables are supplied, in Figure 1 is only the Input variable "ignition on” shown as a signal that at Closing the ignition switch 18 from the terminal K115 of the Ignition lock is supplied and the control unit 15 the Commissioning of the internal combustion engine displays.
  • the control unit 15 itself comprises at least one central one Computer unit 19 and memory 20.
  • control unit 15 are control signals for injection and ignition for Corresponding components of the Internal combustion engine formed. These signals are over the Outputs 21 and 22 of the control unit 15 delivered.
  • the Power is supplied to the control unit in the usual way Way from the battery 23 via a switch 24, the during the operation of the internal combustion engine as well possibly closed during a run-on phase. The signal processing described below and Evaluation takes place in control unit 15.
  • crankshaft 11 With the control system shown in Figure 1 can the angular position of the crankshaft 11 during operation the internal combustion engine can be detected at any time.
  • a singularity in the signal S1 which the Reference mark corresponds to the crankshaft.
  • the assignment between crankshaft 11 and camshaft 25 usually is as well known as the assignment between the position the camshaft and the position of the individual cylinders Internal combustion engine, after recognizing the reference mark synchronization takes place, but only if a for the phase position characteristic signal is present.
  • both the speed curve and the intake manifold pressure curve can be used as signals S2 for synchronization.
  • the Evaluation can take place immediately after the start of the rotation of the engine in unfired operation take place before the first one Injections or ignitions are triggered.
  • At first Revolutions without firing are both the speed curve as well as the intake manifold pressure characteristic of the first or second crankshaft revolution.
  • After the start of the normal engine operation, especially at high Engine speeds or speed changes can possibly Speed curve no longer for determining the motor position be used. If synchronization occurs during the Operation must be carried out by means of Evaluation of the intake manifold pressure signal.
