Definitions

  • the object of the present invention is therefore to provide a method and a control device for cylinder synchronization of an internal combustion engine, by means of which the disadvantages of the prior art are at least partially overcome.
  • the determined cylinder-specific fill quantities can be used at S7 as a basis for adapting the future cylinder-specific fill quantities of fresh air and / or fuel.
  • optimized fill quantities can now be introduced into the respective cylinder.
