Abstract: Methods and systems are provided for controlling fuel injections by a fuel injector in a cylinder of an internal combustion engine. First and second fuel injections are applied in each cycle of a piston in the cylinder. First and second electronic control signals are applied to the fuel injector to generate first and second fuel injections by the fuel injector during a first cycle of the piston. A hydraulic fusion state of the generated first and second fuel injections is determined. A parameter of the applied first and second electronic control signals is adjusted in response to determining the hydraulic fusion state and applied to the fuel injector to generate first and second fuel injections by the fuel injector during a second cycle of the piston subsequent to the first cycle.
