Patent ID: 7131428

Claim:
A method for controlling fuel injection in an internal-combustion engine provided with an electroinjector comprising: an electroactuator; and an atomizer, the atomizer comprising an injection nozzle and a pin, which is movable along an opening stroke and a closing stroke for opening/closing said nozzle under the control of said electroactuator; the electroinjector performing dosage of the fuel by modulating in time opening of the pin of the atomizer according to the pressure of supply of the electroinjector itself; the method comprising the acts of: supplying to said electroactuator a first electrical command and at least a second electrical command that are sufficiently close to one another as to displace said pin with a profile of motion without any discontinuity in time, wherein said second electrical command is supplied before said first electrical command reaches zero; and causing said pin to perform a first opening displacement and a second opening displacement, respectively based on said supplied commands.
