  • Control circuit for controlling at least one solenoid valve for fuel metering in an internal combustion engine
    Patent number: 6526945
    Abstract: A control circuit for controlling solenoid valves for fuel metering in an internal combustion engine (banks I and II) includes a recharge circuit having a throttle coil in series with a diode and with a storage capacitor, as well as an FET power transistor connected in parallel with the series circuit of the diode and the storage capacitor. The solenoid valves of the individual banks are switched off during the rapid extinguishing with a voltage produced by the recharge circuit. To minimize the influence of the supply voltage, which comprises a wide range, the HS-FET is switched off during the rapid extinguishing phases.
