Definitions

  • the invention relates to a device for regulating fuel injection and ignition in an internal combustion engine according to the preamble of the main claim.
  • the control unit In multi-cylinder internal combustion engines with electronically controlled injection and ignition, the control unit usually calculates when and how much fuel should be injected per cylinder and when the appropriate ignition timing is. In order that these calculations can be carried out correctly, the respective position of the crankshaft or camshaft of the internal combustion engine must be known. It is therefore common and is described, for example, in EP-A1 0 371 158 that the crankshaft and the camshaft are included one disc each are connected, a single marking is arranged on the surface of the disc connected to the crankshaft, while on the upper surface of the disc connected to the camshaft there is a marking which extends over an angle of 180 °.
  • the two rotating disks are scanned by suitable fixed sensors, from the chronological sequence of the pulses supplied by the sensors, a clear statement about the position of the crankshaft and camshaft is obtained, depending on which control signals for injection and ignition are generated in the control unit.
  • the injection takes place for the first time as a function of the camshaft sensor signal into the cylinder group, which predominantly has closed intake valves.
  • the injection for the next cylinder group is placed on the level change of the camshaft signal or sequentially after the synchronization.
  • the known device has the disadvantage that the first injections take place with undefined advance angles and a large number of injections take place at an early point in time when the fuel pressure build-up phase has not yet been completed.
  • the inventive device with the features of claim 1 has the advantage that the position of the crankshaft and camshaft can be determined particularly quickly, so that a very early start of sequential injection is possible.
  • the first injections take place at a defined pre-storage angle and at the latest possible time, so that these injections take place at a largely secure fuel pressure.
  • reliable phase-correct cylinder detection and ignition output are obtained after a particularly short rotation angle, so that short starting times result.
  • FIG. 1 shows a rough overview of the arrangement of the crankshaft or camshaft together with the associated sensors and the control unit, in which the calculations for regulating the injection and ignition run.
  • Figure 2 control signals or signals emitted by sensors are plotted over time during the starting phase of an internal combustion engine.
  • FIG. 1 the components of an internal combustion engine required to explain the invention are shown by way of example, 10 being an encoder disk which is rigidly connected to the crankshaft 11 of the internal combustion engine and has a multiplicity of similar angular marks 12 on its circumference.
  • a reference mark 13 is provided, which is realized, for example, by two missing angle marks.
  • a second encoder disk 14 is connected to the camshaft 15 of the internal combustion engine and has a mark 16 on its circumference which extends over an angle of 180 °. At 17, the connection between the crankshaft and camshaft, which rotates the camshaft at half the crankshaft speed, is symbolically represented.
  • the two encoder disks 10, 14 are scanned by sensors 18, 19, for example inductive sensors or Hall sensors, for example static Hall sensors, the signals generated when the angular marks pass in the sensors are either processed in the same way and fed to a control unit 20 or only in Control unit 20 is prepared in a suitable manner, preferably square wave signals are formed, the rising edges of which correspond to the start of an angle mark and the falling edges of which correspond to the end of an angle mark. These signals or the time sequences of the individual pulses are evaluated in the control unit.
  • the control unit 20 receives, via various inputs, further input variables required for the control or regulation of the internal combustion engine, which are measured by various sensors. Examples of such sensors may be mentioned: a temperature sensor 21, which measures the engine temperature, a throttle valve sensor 22, which registers the position of the throttle valve, a pressure sensor 23, which measures the pressure in the intake pipe or the pressure in a cylinder of the internal combustion engine. Furthermore, an "ignition on" signal is supplied via the input 24, which is supplied by the terminal Kl.15 of the ignition lock when the ignition switch 25 is closed.
  • control unit which includes computing or storage means (not shown) and a permanent storage designated 30, provides signals for the ignition and injection, for corresponding components of the internal combustion engine, not specified. These signals are emitted via the outputs 26 and 27 of the control unit 20.
  • further sensors can be used, the signals of which are fed to the control unit, and the control unit 20 can also emit further signals required for regulating the internal combustion engine. It is not absolutely necessary that all of the sensors shown are present.
  • the control unit 20 is supplied with voltage in the usual way with the aid of a battery 28, which is connected to the control unit 20 via a switch 29 during operation of the internal combustion engine and, in a further embodiment, during a run-on phase after the engine has been switched off.
  • the position of the crankshaft 11 and the camshaft 15 can be detected at any time during operation of the internal combustion engine, since the assignment between the crankshaft and the camshaft is known as well as the assignment between the position of the camshaft and the position of the individual cylinders , After the reference mark has been recognized, synchronization can take place and, after synchronization has taken place, the injection and the ignition can be controlled or regulated in a known manner.
  • control or regulation of an internal combustion engine is described for example in DE-OS 39 23 478 and is therefore not explained in detail here.
  • the starting conditions are, for example: Fig 2: Injection pre-storage: 30 ° KW after LWOT Starting position: 48 ° KW before OT1 First injection after: 150 ° KW First ignition after: 480 ° KW Start of ramp-up after: 480 ° KW Fig 3: Injection pre-storage: 72 ° KW after LWOT Starting position: 60 ° KW before OT3 First injection after: 54 ° KW First ignition after: 348 ° KW Start of ramp-up after: 348 ° KW Fig 4: Injection pre-storage: 102 ° KW according to LWOT Starting position: 72 ° KW before OT4 First injection after: 96 ° KW First ignition after: 360 ° KW Start of ramp-up after: 360 ° KW Fig 5: Injection pre-storage: + 6 ° KW before LWOT Starting position: 54 ° KW before OT5 First injection after: 120 ° KW First ignition after: 474 ° KW Start
  • FIG. 2a shows the control signals A, B, C, D and E emitted by the control unit for the injection valves EV1 to EV5, the injections being characterized by the minima.
  • the hatched areas indicate the first injection.
  • the area X denotes a phase during which an intake valve is open. The first firings that take place in the individual associated cylinders are symbolized by an arrow.
  • the upper signal F indicates the course of the output signal of the camshaft sensor or the phase sensor, with this signal a phase change occurs every 360 ° KW with the selected sensor disk.
  • the first edge change is referred to as the M1 mark.
  • the lower signal G shows the course of the ignition signals.
  • the speed signal H and the output signal J of the crankshaft encoder are plotted in FIG. 2c, indicated for a corresponding encoder disk with a multiplicity of angular marks of the same type and a reference mark represented by two missing angular marks.
  • the start of the internal combustion engine is initiated via the ignition lock 25.
  • the control unit 20 applies voltage to the individual systems or transmitters, and the electric fuel pump relay is actuated, so that the fuel pump begins to deliver the fuel.
  • control unit is usually not yet aware of the exact angular position of the crankshaft or camshaft. However, if a run-on detection is carried out as described in German patent application P 42 30 616, the exact angular position is already known at this point in time and the control unit can immediately start calculating the times that are important for the injection.
  • crankshaft sensor emits speed-dependent pulses.
  • FIGS. 3 to 5 show the same situation as in FIG. 2, but with a different starting position of the engine and thus also with different injection angles.
  • the reference mark BM can be seen in the output signal of the crankshaft sensor in FIGS. 3c and 5c, it corresponds to a mark designated as mark M2 or M4.
  • the mark M3 is determined by the first edge change of the camshaft sensor signal.
