Definitions

  • the target operating mode results among other things from the respective operating state or function of the internal combustion engine. For example, homogeneous operation can be useful for a cold start of the internal combustion engine. In contrast, homogeneous operation may be preferable in the event of a defect.
  • an operating mode map can be provided which is particularly suitable for influencing the normal operation of the internal combustion engine. The control unit determines the target operating mode from these and other such operating states or functions of the internal combustion engine.
  • This object is achieved according to the invention in a method of the type mentioned at the outset in that an operating mode requirement is determined as a function of whether the individual operating modes are able to generate the requested torque while observing predetermined lambda limits.
  • the control unit can determine an operating mode requirement depending on whether the individual operating modes are able to generate the requested torque while observing predetermined lambda limits.
  • FIG. 2 shows a schematic block diagram of an exemplary embodiment of a method according to the invention for operating the internal combustion engine of FIG. 1.
  • a tank ventilation line 16 leads from a fuel tank 15 to the intake pipe 7.
  • a tank ventilation valve 17 is accommodated in the tank ventilation line 16, with which the amount of fuel vapor supplied to the intake pipe 7 from the fuel tank 15 can be adjusted.
  • the tank ventilation line 16 and the tank ventilation valve 17 form a so-called tank ventilation.
  • a so-called stratified operation of the internal combustion engine 1 the throttle valve 11 is opened wide.
  • the fuel is injected from the injection valve 9 into the combustion chamber 4 during a compression phase caused by the piston 2, specifically locally in the immediate vicinity of the spark plug 10 and at a suitable time before the ignition point.
  • the fuel is ignited with the aid of the spark plug 10, so that the piston 2 is driven in the now following working phase by the expansion of the ignited fuel.
  • the resulting torque largely depends on the injected fuel mass in shift operation.
  • the shift operation is essentially for the . Idle operation and the partial load operation of the internal combustion engine 1 are provided.
  • the method of FIG. 2 assumes that the various functions described each generate operating mode requests. These operating mode requests are triggered by each of the functions with a request byte corresponding to the target byte. In this request byte, the individual bits correspond to the corresponding bits of the target byte.
  • target byte and the request bytes are binary data words which are stored in the control unit 18 and in which each operating mode is represented by a specific bit. It should be noted that the target byte and the request byte - as described - have different meanings and must therefore be kept separate.
  • Each of the blocks 22, 23, 24 and 25 sets the bit which it can influence in the request byte 21 to "1" if the associated operating mode is able to generate the requested torque and to comply with the operating mode-dependent lambda limits. If this is not the case, the corresponding block sets the associated bit to "0".

Abstract

L'invention concerne un moteur à combustion interne notamment destiné à un véhicule automobile. Ce moteur est doté d'une chambre à combustion dans laquelle du carburant peut être injecté dans au moins deux modes de fonctionnement. Un dispositif de commande permet de commuter entre les différents modes d'injection selon un mode de fonctionnement théorique. Ce dispositif de commande permet de détecter le mode de fonctionnement nécessaire en vérifiant si les différents modes de fonctionnement sont en mesure de produire le moment de couple nécessaire tout en respectant les limites lambda données.
