The invention provides a redundant dual-coil electromagnetic valve, which comprises a valve body, an iron core which is arranged in the valve body, and induction coils which are wound on a coil skeleton, wherein, the induction coils comprise an upper induction coil and a lower induction coil; a redundant coil which is wound on a redundant coil skeleton is arranged at the lower part of each of theinduction coils; a public iron core is arranged in the induction coils and the redundant coil; a return spring mounting hole is arranged on the public iron core; the return spring is arranged in the return spring mounting hole; and an armature is arranged on the return spring. The invention can simultaneously realize the individual control over a fuel oil overflow valve and a nozzle control valveand realize the flexible control over the fuel oil spraying rate of a diesel engine by the matching control over two control valves; the invention can meet the requirements of the diesel engine for oil spraying rules under different operating modes and different loads, enhances the economy of the diesel engine and lowers harmful discharge. The redundant coil enhances the operation reliability of the electromagnetic valve and the diesel engine and ensures the running capability of the diesel engine while on continuous duty.
