Abstract: A system and method of controlling the hydraulic dwell time between a first injection and a second injection performed by a fuel injector of an internal combustion engine are disclosed, in which the injector is equipped with a needle operated by a control valve. A value of a nominal electric dwell time between the first injection and the second injection is determined. An actual instant of hydraulic closing of the fuel injector after the first injection is also determined. A corrected electric dwell time is calculated as a function of the nominal electric dwell time and the actual instant of hydraulic closing of the fuel injector after the first injection. The fuel injector is operated using the corrected electric dwell time.

Abstract: An apparatus and method for operating a fuel injector of an internal combustion engine is disclosed. A first energizing electrical current is supplied to an injector solenoid, causing the opening of an injector control volume and a pressure reduction in said injector control volume, for a first energizing time. The first energizing time is predetermined to avoid that the pressure in the injector control volume approximates a value which would cause an injector needle to raise up and a fuel injection to start. After the predetermined time interval, a second energizing electrical current is supplied to the injector solenoid for a predetermined second energizing time, which is a function of a rail pressure (prail) and a fuel injection quantity.

Abstract: A method and apparatus for energizing a solenoidal fuel injector for an internal combustion engine is disclosed. The fuel injector is electrically connected to a battery capable of providing a battery voltage and to a boost converter capable of providing a boost voltage that is higher than the battery voltage. The boost voltage is applied to a solenoid of the fuel injector to perform a first opening phase of the injector, the energy from the solenoid of the fuel injector is then discharged. A second opening phase of the fuel injector is performed, and followed by a hold phase using the battery voltage (Vbatt). Lastly, a closing phase of the fuel injector is performed.

Abstract: A method and system for operating a fuel injector of an internal combustion engine is disclosed in which the fuel injector is driven by an energizing current profile for an energizing time interval. An energizing current profile is selected for each fuel injection in a fuel injection system from among a plurality of predetermined energizing current profiles based on a function of an engine combustion mode. For each selected energizing current profile, a corresponding energizing time is determined as a function of a common rail pressure value and a fuel quantity value.
