  • Method and device for dosing fuel which is to be injected into a combustion chamber of an internal combustion engine
    Patent number: 7769535
    Abstract: Method for dosing fuel injected into an engine, with a fuel quantity for an injector, the fuel quantity being divided into pilot and main injections for respective activation duration having activation duration corrective value, the method may include storing correlation data between fuel injection quantity and activation time under at least a state parameter of the injector, wherein the fuel injection quantity includes reference total injection quantities determined for predetermined operating states of the engine, determining a present operating state of the engine, placing the engine into one of the predetermined operating states, determining a present total injection quantity and a reference total injection quantity in one of the at least a state parameter of the injector, and defining the respective activation duration corrective value for the pilot and main injection considering a difference between the reference total injection quantity and the present total injection quantity.
