Gasoline engine ignition mechanism including eccentric active pre-combustion chamber manufacturing method

The invention relates to an ignition mechanism of a gasoline engine including an eccentric active pre-combustion chamber. The ignition mechanism of a gasoline engine includes: a cylindrical connector, an injector installation hole penetrating the upper and lower end surfaces of the connector, a spark plug installation hole penetrating the upper and lower end surfaces of the connector, and a pre-ignition connected to the outer peripheral surface of the connector through a thread Chamber, a pre-chamber injector that works with the injector mounting hole, and a pre-chamber spark plug that works with the spark plug mounting hole; in the present invention, the ignition position of the pre-chamber is centered, so that the flame surface is more symmetrical The development of jet nozzle holes in each pre-combustion chamber shortens the time difference between the flame surface reaching the jet nozzle holes in each pre-combustion chamber, and reduces the asymmetry of the jet time of the jet nozzle holes in each pre-combustion chamber
