Air-breathing engine plasma ignition system

The invention discloses an air-breathing engine plasma ignition system, and belongs to the technical field of engine ignition. The system involves an air introducing pipeline, an oil supplying pipeline, a power supply and an igniter shell; a high-voltage electrode and a low-voltage electrode are arranged in the igniter shell, the high-voltage electrode and the low-voltage electrode are both hollowcylinders, the low-voltage electrode is coaxially arranged at the exterior of the high-voltage electrode, and an annular cavity is formed between the high-voltage electrode and the low-voltage electrode; the two ends of the oil supplying pipeline communicate with an oil supplying system of an engine and the annular cavity in the igniter shell; the two ends of the air introducing pipeline communicate with an air inlet of the engine and the annular cavity in the igniter shell; and the power supply is arranged in the engine shell and is electrically connected with the high-voltage electrode andthe low-voltage electrode
