FIELD: mechanical engineering; diesel engines.
SUBSTANCE: invention relates to fuel injection control devices of diesel engines. Proposed unit injector control device contains time relay, group of NAND gates connected by inputs to control input of circuit. Outputs of NAND gates are connected to input of powerful transistor switches whose outputs are connected to outputs of electromagnet coil. Two time relays and group of NAND gates are connected by inputs to control input of circuit. Outputs of NAND gates are connected to inputs of powerful transistor switches which form bridge circuit for connecting coil of electromagnet to form forcing and demagnetizing pulses of current. One lead of coil is connected through powerful switch, diode and differentiating RC-circuit connected in parallel and ballast resistor to minus pole of storage battery. Second lead of coil is connected through powerful switch and arm of bridge to plus pole of battery connected to bridge supply diagonal to form holding pulse.
EFFECT: simplified design, increased reliability and improved design of nozzle valve.
