Driving circuit for at least one electromagnetic valve for fuel metering in an internal combustion engine
DRIVE
November 14, 2001
The drive circuit has a first switching device (115,116) switched off to minimize battery voltage dependency during rapid transitions and a re-charging circuit (1) that supplies voltage to the magnetic valve(s) (100-102;200-202) via a third switching device (140,141) during a booster phase from energy stored in a storage capacitor (145). The storage capacitor is charged with a pre-stabilized recharging voltage produced from the battery voltage.
