A diesel engine speed control device

Abstract

The invention discloses a diesel engine speed control device, comprising a shell, an inner shell, a microprocessor, a linear driving mechanism, a fuel injection pump, a transmission part and a signal collection part, wherein the shell comprises an outer shell and a front cover; the inner shell which is a breathable netty shell is arranged on the front cover, and a plurality of test wires are arranged in the inner shell; the linear driving mechanism is connected to the microprocessor by a wire; the transmission part comprises a first connecting rod, a second connecting rod and a third connecting rod, the first connecting rod is fixed to the shell, one end of the first connecting rod is hinged to the linear driving mechanism while the other end is hinged to the other end of the second connecting rod, one end of the second connecting rod is hinged to the fuel pump ratch of the fuel injection pump, and the third connecting rod is hinged to the second connecting rod; the signal collection part is connected to the microprocessor by a wire; the wire has the same material with the test wires, the wire and the test wires are respectively include an aluminum core the surface of which is provided with a plurality of grooves along the axial direction, refined copper with purity of more than 99.97% is arranged in the grooves, and the outer part of each aluminum core is also sequentially covered with a refined copper film layer and a grapheme layer.

Description

technical field [0001] The invention relates to the technical field of diesel engine accessories, in particular to a diesel engine speed regulating device. Background technique [0002] Existing mechanical diesel engine governors have some disadvantages. During the speed regulation process, it is difficult for the flying block system and spring of the mechanical governor to precisely cooperate with the fuel injection pump, which makes the fuel injection quantity inaccurate and the response speed is slow, which makes the diesel engine under load. When the difference is large, the speed and torque change greatly, and the inaccurate fuel injection quantity may cause insufficient combustion, thereby wasting fuel. However, during the use of general wires, such as when used in harsh conditions such as humid environments, the exposed wires are easily damaged, resulting in short circuits and other faults. Regular maintenance is usually required to avoid accidents and the operation ...

[0002] Existing mechanical diesel engine governors have some disadvantages. During the speed regulation process, it is difficult for the flying block system and spring of the mechanical governor to precisely cooperate with the fuel injection pump, which makes the fuel injection quantity inaccurate and the response speed is slow, which makes the diesel engine under load. When the difference is large, the speed and torque change greatly, and the inaccurate fuel injection quantity may cause insufficient combustion, thereby wasting fuel

However, during the use of ordinary wires, if they are used in harsh conditions such as humid environments, the exposed wires are easily damaged, causing short circuits and other faults.

Usually requires regular maintenance to avoid accidents, time consuming to operate
