Definitions

  • the invention relates to a device for controlling a 5. Internal combustion engine according to the preamble of claim 1 or 5.
  • crankshaft turns twice within one working cycle turns, can only by scanning the crankshaft Do not clearly determine the phase position of the internal combustion engine. So this is possible, usually with the help of a second sensor the camshaft-related encoder disk attached to its Surface has a reference mark, scanned. Because the camshaft The control unit can only turn once during a work cycle the signal delivered by the camshaft sensor with a single pulse recognize the phase position of the internal combustion engine per cycle and one Carry out synchronization. Such a system is used, for example, in the German patent application P 42 30 616.7 described.
  • a device for regulating an internal combustion engine without Phase sensor works is known from EP-A-576 334. At this The top dead center of a cylinder is determined in each device. In addition, predeterminable injections are suppressed, and thereby Combustion misfires generated are evaluated for phase detection.
  • From US-A-4 843 556 is a device for controlling a Internal combustion engine known in which the smoothness by varying the Zündoder Injection point is influenced. Thereby also the Effects of the variation of the ignition or injection timing on the Speed evaluated.
  • the device according to the invention for regulating an internal combustion engine has the advantage that no phase sensor, so no sensor, the one with the Camshaft rotating disc scans is needed, but only a sensor that determines the position of the crankshaft.
  • phase detection together with a Device is used in which the position of Crankshaft and thus the position of the camshaft as well the phase position after the engine runs out is registered and saved and this knowledge at Reactivating the internal combustion engine is initially taken into account and a phase detection immediately after the start expires, on the basis of which it is recognized whether the assumed Phase position was correct.
  • Figure 1 are those necessary to explain the invention Components of the control system of an internal combustion engine shown schematically.
  • a sensor disk with 10 referred to, the rigid with the crankshaft 11 of the Internal combustion engine is connected and on its circumference Has a large number of similar angle marks 12.
  • a reference mark 13 existing, for example, by two missing angle marks is realized.
  • the encoder disc 10 is the sensor 14, for example one inductive pickup or a Hall sensor, the sampled generated when passing the angle marks in the transducer Signals are in the control unit 15 in a suitable manner processed.
  • the control unit 15 receives further, via various inputs, for the control or regulation of the internal combustion engine required input variables from different sensors be measured.
  • these sensors are 17 designated.
  • An "ignition ON” signal is sent via another input supplied.. That when closing the ignition switch 18 of terminal 15 of the ignition lock is supplied.
  • the control unit 15 comprises at least one central one Processor unit 18 and memory 19.
  • Ignition and injection signals for no closer designated corresponding components of the internal combustion engine determined. These signals are on the outputs 20 and 21 of the Control unit 15 issued.
  • the power supply to the control unit 15 is carried out in the usual way Way with the aid of a battery 22, which has a switch 23 during the operation of the internal combustion engine and during a control phase controlled by the control unit itself after switching off of the engine is connected to the control unit 15.
  • the Follow-up phase can also be done by other means, e.g. by means of Control device existing memory can be realized.
  • the position the crankshaft 11 during operation of the internal combustion engine can be recorded at any time. Because the mapping between crankshaft and camshaft is known as well as the mapping between the position of the camshaft and the position of the individual Cylinder, can be after recognizing the reference mark Synchronization take place, however, only if one for the Phase characteristic signal is present.
  • FIG 2 are those for ignition and injection essential sizes above the crankshaft angle in degrees KW applied.
  • a) shows the correlations with the correct one Phase position and b) in the wrong phase position (incorrectly assumed Phase position).
  • LWOT is the point at which a cylinder in the so-called load change top dead center located.
  • ZOT is the top dead center of the cylinder at which is ignited. That an ignition is triggered by the Arrows 24 symbolized in Figure 2.
  • the area 25 is each the area in which the inlet valve is open and with 26 the injection pulses are designated.
  • the detection of the phase position after the start or in operation, for example, idle is done by the Control unit specifically changes the forward angle ⁇ makes.
  • By changing the displacement angle from one Working cycle to the next is in the wrong phase position Injection shifted to the previous one Working cycle causes, which initiates a speed change becomes.
  • This change in speed is evaluated and Phase synchronization used. It will Speed signal obtained from the signal from the crankshaft sensor, which delivers a speed-dependent pulse sequence that in the control unit 15 is used in the usual way for speed determination.
  • the preliminary angle in the first Working cycle e.g. a setpoint of 180 degrees KW Load change TDC.
  • the Target advance angle by 360 degrees KW to 540 degrees KW before LWOT elevated.
  • the assumed phase position is wrong (b)
  • that is Actual storage angle by 360 degrees KW compared to Target advance angle shifted so it is in the first Working cycle of the actual advance angle by 540 degrees KW before first load change top dead center.
  • the actual advance angle 900 degrees KW before the second Load change TDC. This is equivalent to 180 KW before first load change TDC.
  • the Actual advance angle is then 540 degrees KW before the third Load change TDC.
  • control unit can be Injections detect whether the assumed phase position is correct or is wrong and in case of wrong phase position one Make correction.
  • a phase sensor as used in conventional systems is therefore not required.
  • phase detection described can in known injection and Ignition systems such as SEFI (sequential fuel injection), knock control, rotating high voltage distribution, static high-voltage distribution, two-spark coils, etc. Systems are used.
  • SEFI single fuel injection
  • knock control rotating high voltage distribution
  • static high-voltage distribution static high-voltage distribution
  • two-spark coils etc. Systems are used.
