The invention provides a spiral vortex pre-combustion chamber ignition system. The spiral vortex pre-combustion chamber ignition system comprises a pre-combustion chamber (1), a spark plug (2), a jet flow valve (3), a main combustion chamber (4), at least one air inlet hole (5) and at least one jet flow hole (6), wherein the pre-combustion chamber (1) is arranged in a cylinder cover (8) above the main combustion chamber (4) near the center of an air cylinder (7); the main combustion chamber (4) is composed of an air cylinder (7), the bottom face of the lower portion of the cylinder cover (8) and the top face of a piston (15); and the pre-combustion chamber (1) is provided with an upper space (11) and a lower space (12); According to the ignition system, high pressure difference is established between the main combustion chamber and the pre-combustion chamber in the air inlet process of the pre-combustion chamber, so that high-speed inlet air flow is generated, and a spiral vortex model is established; and acc
