The invention discloses a pre-combustion chamber structure with a wide ignition boundary. The pre-combustion chamber structure comprises a spherical combustion chamber, a mounting seat (6) and a flame transfer tube (7), the flame transfer tube (7) penetrates through a central hole of the mounting seat (6), and the upper end of the flame transfer tube (7) is lapped on the upper end surface of the mounting seat (6); the spherical combustion chamber (1) is provided with a flange edge, and the upper end of the mounting seat (6) is in threaded connection with the flange edge. The gas inlet structure on the flame transfer tube is reasonably designed, gas flow is guided to enter a specific area in the pre-combustion chamber in a layered mode, a multi-vortex-system structure is induced to be formed, oil and gas distribution near the igniter is improved, mixing is enhanced, and the ignition characteristic of the pre-combustion chamber is obviously improved. 本发明公开了一种宽点火边界的预燃室结构，其括球形燃烧室、安装座(6)、传焰管(7)；传焰管(7)穿过安装座(6)的中心孔，
