Abstract
A circuit for controlling the energy supplied to electromagnetic injector valves in an electronically controlled fuel injection system is disclosed herein. The disclosed circuitry limits the voltage available to the injector valves to a selected maximum level slightly below the minimum voltage normally obtainable from a vehicle battery recharging system and further limits the maximum current flow through the electromagnetic coil of each open injector valve to a preselected valve. The preselected current value may be changed during operation to minimize energy stored in the magnetic field of the electromagnetic coils.
