Abstract
The invention discloses an automatic speed adjusting device for a small-size two-stroke gasoline engine. The device comprises a carburetor (1), an adjustable-speed motor (3), a circuit controller (4), the engine (5), a flywheel and magnet motor (6) and an engine high pressure pack (7), the adjustable-speed motor (3) is fixed on the carburetor (1) through a mounting bracket (2), engine speed signals of the flywheel and magnet motor (6) which is installed on a crankshaft of the engine (5) are transmitted to the circuit controller (4), after making comparison with a set revolving speed, the circuit controller (4) outputs an adjustable-speed motor revolution signal, the adjustable-speed motor (3) is made to revolve forward or reversely, the accelerator opening of the carburetor (1) is driven by the adjustable-speed motor (3) to be opened or closed for a certain angle, the accelerator opening variation of the carburetor (1) controls the revolving speed of the engine (5), and the engine (5) is made to work at a constant speed under the set revolving speed. By means of the structure, the device has the advantages that the structure is simple and reasonable, the operation and use are convenient, the engine speed is adjusted automatically according to the set revolving speed, the operation is safe and reliable, and the device is capable of meeting emission requirements of the United States and the European Union.
