The present embodiment adopts a speed-regulating double-limit structure, that is, the maximum working stroke of the speed-regulating tension spring 53 is regulated by the regulating element 3 to achieve the effect of limiting the engine rotation speed, and the limiting element 52 is arranged to limit the engine rotation speed, so that the phenomenon of performance deterioration of the diesel engine flying lamp caused by misoperation or improper operation of individuals can be effectively solved, and the operation stability and reliability of the diesel engine are improved.
In one embodiment, the engine speed control device further comprises: an injection pump 56 and an oil limiter 57, the injection pump 56 being provided on the housing 50; an oil limiter 57 is provided on the housing 50. The oil injection pump 56, the oil limiter 57, the speed regulating lever and the speed regulating pull plate are all arranged on the shell 50, the shell 50 is a gear chamber cover, and when the shell is machined, the related positioning measures can be adopted to avoid the problem of inconsistent speed regulating performance caused by the irrelevance of the production and machining of the original positioning holes, and the measures can further improve the positioning precision and the structural stability.
In order to increase the stability of the injection pump 56 on the housing 50, a reinforcement 503 may also be provided on the housing 50, which reinforcement 503 may be used to support the tail of the injection pump 56.
In this embodiment, referring to fig. 8, the mounting position of the engine speed adjusting pull plate is higher than the outer side surface of the gear chamber cover, so that accessibility during installation, debugging, maintenance and disassembly of the diesel engine can be improved; and the decorative plate 58 is arranged above the gear chamber cover, so that the speed regulation pull plate can be protected from being corroded by water stains and oil stains in the operation process, the problem of elastic force attenuation caused by the corrosion is avoided, and the reliability and the service life of the system are improved.
It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
