Definitions

  • the invention is based on an electronic control system for an internal combustion engine according to the preamble of the main claim.
  • Such an encoder system is, for example, from the DE-OS 43 04 163 known.
  • the encoder system described there is used in a device for controlling the Fuel injection in an internal combustion engine if possible quickly after starting the engine to generate correct injection pulses so that a faster Speed ramp is possible.
  • the electronic control system for a Internal combustion engine with the features of claim 1 Advantage that a compared to the known facilities further reduction of the start time is possible. Achieved is this advantage by in the control unit of the internal combustion engine the position of the internal combustion engine, i.e. the Angular position of the crankshaft and / or camshaft and the cylinder position is determined until the time at which all Waves have stopped. Just before this Standstill occurs, i.e. at a time when the Speed of the internal combustion engine a predeterminable value, the is also referred to as the minimum speed, at least one additional injection is triggered. This injection takes place in an inlet valve that shortly before the internal combustion engine comes to a standstill is.
  • Another advantage of the invention is that it can be used in all internal combustion engines that either have an absolute angle encoder system that immediately provides a clear signal after switching on or the carry out a run-out detection, the standstill position immediately after switching on again.
  • the electronic Control system related to an internal combustion engine can be used with start / stop systems.
  • the internal combustion engine to save fuel independently under specified conditions off and on again.
  • the control unit is not switched off and detects whether one of the Shafts of internal combustion engines has rotated.
  • An automatic start / stop is usually between the ignition and the stop and start of the internal combustion engine (KL15) not switched off.
  • the restart can be done without actuation the starter, it is also possible the starter to operate and additionally with the injection according to the invention to support the starter to get a quick one To achieve speed ramp-up.
  • Figure 1 which is largely known from DE-OS 43 04 163 is necessary to explain the invention
  • Components of an internal combustion engine shown as an example 10 denotes an encoder disk, which rigidly connected to the crankshaft 11 of the internal combustion engine is and on its circumference a variety of similar angle marks 12 has.
  • a reference mark 13 which is exemplary is realized by two missing angle marks.
  • a second encoder disk 14 is connected to the camshaft 15 Internal combustion engine connected and has on its circumference Segment 16 or possibly further segments 16a, b, c of different lengths with which the phase position the reference mark on the crankshaft pulley becomes.
  • At 17 is the existing between the crankshaft and camshaft Connection that the crankshaft at half crankshaft speed turns, symbolizes. From knowledge of the angular position the crankshaft or camshaft can be known the position of the internal combustion engine, for example what the cylinder position is or which intake valves are open or closed.
  • the two encoder disks 10, 14 are supported by sensors 18, 19 scanned when the angle marks pass in the Signals generated by sensors become, for example, square-wave signals processed and evaluated in the control unit 20. From the chronological sequence of the individual edges of the square-wave signals both the speed and the information with regard to the angular positions of the crankshaft or camshaft win.
  • the control unit 20 receives further, via various inputs, for the control or regulation of the internal combustion engine required input quantities from corresponding sensors 21, 22, 23 can be measured.
  • an "ignition on” signal is input 24 supplied that when the ignition switch 25 is closed by the Terminal KL15 of the ignition lock is supplied. Via clamp KL15 can also be connected to the starter of the internal combustion engine actuate.
  • control unit 20 does not provide this computing or storage means shown and one with 30 designated permanent memory includes, signals for the ignition and injection for unspecified corresponding ones Components of the internal combustion engine are available. These signals are via the outputs 26 and 27 of the control unit 20 delivered.
  • the control unit 20 is supplied with voltage in usually with the help of a battery 28, which has a Switch 29 during operation of the internal combustion engine as well as during a run-on phase after the engine has been switched off is connected to the control unit 20.
  • a boundary condition for restarting for example be provided that after a gas request, that is, after the accelerator pedal is actuated, the internal combustion engine is started again. Since in automatic start / stop between Stop and start of the engine the ignition lock KL15 usually not switched off, the start can be very done quickly.
  • a possible course of action by the electronic control system can be represented as follows: If the control unit 20 detects that the internal combustion engine corresponding control pulses are to be switched off generates a shutdown of injection and / or ignition cause, there are no more burns and the engine is turned off. As a result of her However, indolence turns for a while, during this time there is a leak detection, while in the control unit the angular positions of Crankshaft and / or camshaft as well as the cylinder positions be determined. Furthermore, speed measurements are also carried out carried out. This leakage detection ultimately provides the parking position of the internal combustion engine or Motors.
  • the speed signals in the shutdown phase are as Reverse angle included in the starting position. Is in during the shutdown phase an inadmissible twisting of the engine, for example recognized across a compression point, the following start algorithm is prohibited. Is one Rotation direction detection before, the rotation angle during the parking position included in the starting position.
  • control unit 20 requests "engine start” recognized, is in the cylinder or cylinders, the one or the other after the compression point (ZOT), an ignition is issued.
  • This ignition ignites that due to the last one Flammable injections prior to standstill Air-fuel mixture. This will start the engine to turn immediately. After the next cylinder the ZOT has reached an ignition in this cylinder too triggered.
  • the position of the internal combustion engine continue by means of the known starting position and the Encoder signals determined during start-up. A additional support for the rotary movement by the starter the internal combustion engine is possible.
  • Engine start begins like that from DE-OS 43 04 163 known device for controlling the fuel injection injection in an internal combustion engine. It can be referred to as zero or first splashes Injections take place. After the synchronization, so after the reference mark has been recognized by the control unit to one of the well-known controls for ignition and injection (For example, sequential fuel injection SEFI).
  • the described electronic control system can be used with all Internal combustion engines are used, the appropriate encoder systems have, for example, with incremental encoder systems with or without phase encoder or with segment systems with encoder on the crankshaft and / or camshaft as well as brands in the area of the ignition OT.
  • FIG 2 is an example of a four-cylinder engine the relationship between injection and ignition in the shutdown phase, in the shutdown position of the internal combustion engine and the start phase, with the shutdown phase with Ab, the start phase with St and the engine shutdown position are designated with MA.
  • MA Areas of intake valves E1 to E4 that correspond to the corresponding Cylinders are assigned, open.
  • In the intake valves E2 and E3 are injected when turned off, which are designated with A1A or A2A.
  • In the intake valve E4 is an injection before the start of rotation Internal combustion engine sold. This injection is called Zero splash N designated. Once the engine has started rotating Injections labeled EEE. These injections may take place before synchronization.
  • Z0 to ZX are ignitions in the individual cylinders.
  • Z0 denotes the ignition of the when it is turned off injected fuel (ignition according to ZOT).
  • Z1 designated the ignition of the fuel injected when switching off (Regular ignition).
  • Z2 to Z4 the ignitions are then remaining cylinders designated when starting with fuel be supplied. The following applies with regard to the cylinder position: With the A1A injection, the cylinder is still at the start before top dead center (ZOT), so there is still one "regular" ignition possible. At injection A2A stands the cylinder when restarting after ZOT.
