Description

Technical Field

[0001] The utility model belongs to the technical field of speed regulating devices, and in particular relates to a speed regulating device and a diesel engine. Background Art

[0002] The traditional water-cooled single-cylinder diesel engine adopts a mechanical knob speed control mechanism. When the speed control knob is placed at the top of the slide, the diesel engine is in a non-fuel injection state. When the speed control knob is placed at the bottom of the slide, the diesel engine is in a full throttle state. The speed control knob can be fixed at a certain position of the slide by tightening, thereby fixing the diesel engine speed. When parking, the speed control knob needs to be loosened and placed at the top of the slide.

[0003] Since the speed knob needs to be adjusted manually, the idle speed of the water-cooled single-cylinder diesel engine cannot be quickly controlled each time it runs, and requires careful manual adjustment. At the same time, there is a risk of the diesel engine stalling due to excessive adjustment of the knob.

[0004] Therefore, it is urgent to develop a new speed regulating device and a diesel engine to solve the above problems. Utility Model Content
