1. A control system for a combustion engine having a plurality of cylinders, each of which has associated fuel supply means, which control system comprises:

  • a distributed computer network having a main computer and a number of node computers, each respective node computer being arranged closely to a selected group of the cylinders of the combustion engine and controlling at least the fuel supply means of the cylinders of said group, the main computer and the node computers being connected to a common communication loop transmitting control data from the main computer to the node computers and information from the node computers to the main computer;

    a first switch means arranged at each node computer for setting a node number during installation of the node computer;

    a second switch means arranged at each node computer for setting the total number of cylinders of the combustion engine; and

    the main computer having a number of stored programs, each program used for generating basic control data in the form of at least one of fuel amount and ignition timing for a specific engine type, each node computer including a memory containing cylinder individual relation data for every cylinder of each specific engine type stored in the main computer.
