  "textContent": "A precombustion chamber igniter with a retractable electric glow plug and a cold start control method for a methanol engine are provided. The precombustion chamber igniter includes a fuel injector, a spark plug, and an electric glow plug. The electric glow plug is retractable and has two working positions, at a first position, a heating segment is wholly located in an injection chamber to provide heat energy for the injection chamber, and at a second position, the heating segment is partially located in the injection chamber and passes through a first through hole, and the rest of the heating segment is located in a main combustion chamber of an engine, to provide heat energy for the injection chamber and the main combustion chamber. In a cold start stage of the engine, the heating segment of the electric glow plug is controlled to be located at the second position.",
