Problems solved by technology
[0002] In the current engine field, especially in the field of single-cylinder engines, the speed regulation of the engine mainly adopts a mechanical centrifugal governor. By installing the fuel injection pump assembly on the body, and installing the speed regulating shaft and the speed regulating gear on the crankcase cover, Install the flyweight and sliding sleeve inside the speed regulating gear, install the lever shift fork parts inside the body, install the speed regulating handle and speed regulating panel, speed regulating spring, return spring, etc. outside the body, and the speed regulating system depends on the load during operation The change of the speed regulating gear leads to the change of the speed of the speed regulating gear, thereby changing the centrifugal force of the flyweight and the opening of the flyweight, thereby changing the position of the sliding sleeve and the shift fork, and changing the position of the oil volume control sleeve of the oil pump, through the centrifugal force of the flyweight and external installation The balance of the elastic force of the speed regulating spring is used to determine the position of the oil volume control sleeve of the oil pump, thereby determining the oil volume of the oil pump and controlling the speed of the engine. This mechanical speed regulating structure has matching requirements for the flyweight, sliding sleeve and speed regulating spring. High, the overall speed regulation sensitivity is poor, the accuracy is poor, and the consistency is poor

The invention belongs to the technical field of engines, and relates to a speed regulating system of an engine. According to the technical scheme, the stepping motor is installed on the motor installation plate on the side face of the wind scooper welding piece, the inlet in the front end of the wind scooper welding piece is the engine cooling air inlet, the temperature of the wind scooper welding piece is low, and therefore the stepping motor can work stably and reliably. The speed regulation system is simple in structure, small in change, convenient to install and capable of automatically controlling the fuel quantity of the fuel injection pump of the engine according to changes of loads and changes of the rotating speed of the engine, so that the rotating speed of the engine is accurately controlled, fuel consumption during low-load and no-load running of the engine is reduced, speed regulation precision is high, and the engine runs stably and reliably.
