METHOD FOR DRIVING A SOLENOID VALVE OF A FUEL INJECTOR
A battery supplies power to a solenoid valve at a voltage and by a DC/DC boost converter at a boost voltage that is higher than the battery voltage. Operating parameters of the injector are stored that include at least peak high and peak low currents and peak phase duration. A pull-in phase up is pe...

| description | A battery supplies power to a solenoid valve at a voltage and by a DC/DC boost converter at a boost voltage that is higher than the battery voltage. Operating parameters of the injector are stored that include at least peak high and peak low currents and peak phase duration. A pull-in phase up is performed to current into the solenoid valve when a value greater than the peak high current is reached. Current is monitored into the solenoid and switching on the battery voltage to the solenoid if the current into the solenoid is equal to or lower than, the peak low current, then monitoring the current into the solenoid and powering the solenoid at the boost voltage if the current into the solenoid is still lower than the peak low current. Otherwise powering the solenoid at the battery voltage and performing a hold phase. |
