Abstract
A fuel injection system (1) of a combustion engine includes: at least one fuel injection actuator (3) to inject fuel into a cylinder (2) of the combustion engine, a high pressure fuel supply system to supply the fuel injection actuators (3) with fuel, and a control logic device (12) including an artificial neural network (12A) to calculate pressure correction data (pcd) used to correct pressure waves, PW, generated by at least one actuator of the fuel injection system (1).
Claims15
A fuel injection system of a combustion engine, the fuel injection system comprising:
- a fuel injection actuator adapted to inject fuel into a cylinder of the combustion engine;
- a high pressure fuel supply system adapted to supply the fuel injection actuator with fuel;
- and
- a control logic device comprising an artificial neural network adapted to calculate pressure correction data used to correct pressure waves generated by the fuel injection actuator.
A method for correction of pressure wave of an fuel injection actuator of a fuel injection system, the method comprising:
- calculating pressure correction data by an artificial neural network based on load point information data and pressure data provided by a pressure sensor;
- and
- controlling the fuel injection actuator of the fuel injection system in response to the pressure correction data calculated by the artificial neural network.
A control logic device for a fuel injection system, the control logic device comprising:
- an artificial neural network adapted to calculate pressure correction data used to correct pressure waves generated by an actuator of the fuel injection system;
- and
- a control unit adapted to generate control signals for an fuel injection actuator of the fuel injection system based on the calculated pressure correction data.
