Description
Technical field
The present invention relates to electron speed regulator field, especially a kind of electron speed regulator regulating mechanism.
Background technique
Diesel engine is widely applied dynamic power machine in national economy, and high performance diesel engine speed regulator is in various works
Improve diesel powered performance, economic performance and emission performance under condition, has great importance for energy-saving and emission-reduction.Diesel engine tune
The effect of fast device is to automatically regulate fuel delivery according to different load variations, due to the every fuel delivery per cycle of diesel injection pump with
The position of injection pump ratch and the revolving speed of oil pump are related, it is ensured that reasonable fuel delivery is it is necessary in certain accelerator pedal corner
Under revolving speed, the ratch position of reasonable control oil pump.With the development of electron controls technology, in various mechanical, fluid pressure type tune
On the basis of fast device, various types of electron speed regulators are produced, electron speed regulator can not only reach the function of mechanical governor,
And performance is better than mechanical speed governor, can effectively improve the dynamic property and emission performance of diesel engine.
Summary of the invention
It is an object of the invention to:, fuel delivery larger for existing governor idling oil mass fluctuates big, hypervelocity and stops supplying slowly
Deficiency proposes that one kind based on monolithic processor controlled electron speed regulator, can effectively save the fuel consumption under idling operation, and
It can be effectively reduced the noxious emission of idling operation, governor can realize that idling oil mass is smaller, fuel delivery fluctuation is small, hypervelocity stops supplying
Fast performance has the characteristics that at low cost, structure is simple, can be used for all types of diesel engines.
Present invention provide the technical scheme that a kind of electron speed regulator regulating mechanism, by 1 camshaft, 2 speed probes, 3
Oily control-rod, 8 thread transmissions, 9 steppings electricity are stopped in lever mechanism, 4 oil pump cases, 5 oil pump ratch, 6 displacement sensors, 7
Machine, 10 driving screw rod compositions.Camshaft is connect with speed probe, and oil pump ratch is connect with displacement sensor, lever mechanism with
The connection of oil pump ratch, stepper motor is by driving screw rod to connect with thread transmission and lever mechanism.
The present invention has the prominent advantages that: controlling stepper motor by single-chip microcontroller and injection pump rack movement is driven to adjust oil spout
Amount, and then diesel engine speed is controlled, it takes using single-chip microcontroller as the hardware configuration of core and control algolithm, is become according to different loads
Change automatically regulates fuel delivery, the ratch position of reasonable control oil pump, makes governor that can realize that idling oil mass is smaller, fuel delivery wave
It moves small, hypervelocity and stops having the characteristics that at low cost, structure is simple for fast performance.
Detailed description of the invention
Fig. 1 electronic governor executes structure chart
Specific embodiment
Technical solution of the present invention is described further below by way of attached drawing.
A kind of electron speed regulator regulating mechanism, by 1 camshaft, 2 speed probes, 3 lever mechanisms, 4 oil pump cases, 5 oil
Oily control-rod, 8 thread transmissions, 9 stepper motors, 10 driving screw rod compositions are stopped in pump tooth bar, 6 displacement sensors, 7.Camshaft
It is connect with speed probe, oil pump ratch is connect with displacement sensor, and lever mechanism is connect with oil pump ratch, and stepper motor passes through
Driving screw rod is connect with thread transmission and lever mechanism.
Stepper motor driving injection pump rack movement is controlled to adjust distributive value by single-chip microcontroller, and then is controlled diesel engine and turned
Speed is taken using single-chip microcontroller as the hardware configuration of core and control algolithm, automatically regulates fuel delivery according to different load variations,
The ratch position of reasonable control oil pump makes governor that can realize that idling oil mass is smaller, fuel delivery fluctuates small, hypervelocity and stops for fast property
Can, have the characteristics that at low cost, structure is simple.
