Abstract
The invention discloses a high-speed adjustable magnetor through which rotation speed of a gasoline engine can be optionally set according to needs. The high-speed adjustable magnetor comprises a stator and a rotor. A control circuit of a silicon-controlled rectifier trigger electrode is connected inside an electronic switch of the stator and comprises a current-limiting divider resistor, a shunting bypass, a main-control circuit, an auxiliary circuit, a trigger electrode divider current-limiting circuit and the like. During use, when rotation speed meets the requirement, the control circuit can automatically adjust time for triggering a silicon-controlled rectifier if an accelerator is boosted continuously, so that the trigger time is delayed, starting of the gasoline engine is delayed as well, rotation speed of the gasoline engine is properly decreased and consequently increase of rotation speed caused by boosting of the accelerator is offset. Since rotation speed of the gasoline engine is set and high-speed operation no longer appears during operation, wear of various parts of the gasoline engine is reduced and service life of the gasoline engine is prolonged.
