Definitions

  • the present invention relates to a method for optimization the ignition of an air-fuel mixture for direct starts a spark-ignition internal combustion engine with fuel injection.
  • Such starting methods are known and for example in DE 197 41 294 A1 and DE 197 43 492 A1.
  • she are an integral part of a start-stop strategy for the internal combustion engine and come mainly in city operations for use (stop and go). They serve to save fuel and avoiding or reducing pollutant emissions.
  • the present invention is based on the object Procedure for optimizing the ignition energy for direct starts one spark ignition internal combustion engine with fuel injection specify.
  • a corrected value for the ignition energy is determined and the Ignition of the air-fuel mixture with an ignition energy according to this corrected value.
  • the pressure in the combustion chamber is the first commissioned cylinder comparatively low.
  • This reduced pressure compared to normal operating conditions in the combustion chamber leads to other combustion properties and / or operating states of the internal combustion engine.
  • Through the correction function provided according to the invention it ensures that for each direct start the optimal ignition energy is provided, which is special is important for the first combustion in the first in Commissioned cylinder.
  • the method according to the invention is for every type of ignition system including flame beam, plasma and laser ignition systems suitable. However, it is preferably used in conjunction with coil ignition systems with electrical ignition coil and spark plug used.
  • coil ignition systems that of Ignition coil to be delivered to the spark plug by the properties and charging time of the ignition coil determined. Because the coil properties are unchangeable, is therefore usually the charging time of the ignition coil is used to change the ignition energy.
  • standard value and corrected value for the ignition energy a standard value and corrected value of the charging time of the ignition coil used.
  • the predefined correction function can be any correction function be how to correct and adjust others Operating parameters of internal combustion engines are generally known is.
  • the correction function can one additively or multiplicatively linked to the standard value Correction value or from an interpolation two maps obtained during calibration exist.
  • the The simplest case is one of the operating parameters of the internal combustion engine independent correction function, e.g. B. a fixed multiplicative or additive correction value, used.
  • the Correction function of pressure and / or temperature of the air-fuel mixture dependent in the combustion chamber of the internal combustion engine is.
  • the method according to the invention ensures that the right ignition energy for direct starts a safe ignition of the air-fuel mixture is provided to trigger self-sustaining combustion. In the case of a coil ignition system, this is achieved by the invention intended correction of the charging time of the ignition coil reached. In addition to a perfect ignition and The mixture according to the invention burns the mixture The protection of the ignition coil against overheating is also achieved. Another advantage of the method according to the invention is that it is extremely simple from the electronic Operating control unit (EMS) can be carried out can. Even if the correction function is adapted to pressure and / or temperature of the mixture in the combustion chamber is only one relatively low computing effort of the electronic operating control device required.
  • EMS Electronic Operating control unit
  • curve a represents a voltage signal which requests a specific charging of an ignition coil (not shown) of a spark-ignition internal combustion engine with fuel injection.
  • the charging of the ignition coil thus begins at time t 1 and ends at time t 2 .
  • Curve b shows the energy generated in the ignition coil, which according to curve c is emitted to the spark plug (not shown) in an energy surge in order to generate a corresponding ignition spark.
  • the time period t 2 - t 1 thus represents the charging time TD (dwell time) of the ignition coil, which determines the size of the energy stored in the ignition coil.
  • time period t 2 - t 1 represents the standard value for the charging time IP_TD in normal operation of the internal combustion engine.
  • this standard value is corrected according to the invention (normally increased) in order to ensure that the air-fuel mixture is properly ignited despite the comparatively low pressure in the combustion chamber.
  • the correction function used for this exists, for example from a fixed correction factor.
  • B the default value for the loading time 3 milliseconds and the correction factor 1.5
  • the corrected loading time is 4.5 milliseconds.
  • FIG. 1 shows that the corrected (increased) loading time at a corresponding one Increases the energy generated in the ignition coil leads.
  • Fig. 2 illustrates for this an embodiment in which an additive Correction factor of the temperature and pressure in the Combustion chamber depends.
  • IP TD the loading time the ignition coil during normal operation of the internal combustion engine entered.
  • charging time TD the ignition coil uses the default value IP_TD.
  • IP_TD becomes the Corrected loading time with an additive correction value IP_TD_COR.
  • This additive correction value becomes apparent during calibration extracted map 5 in which the correction value over temperature and pressure (inputs 3 and 4) is applied.
  • the one obtained in step 6 by addition corrected loading time TD is then at output 1 for the purpose of further Processing available.
