Description
Technical field
The present invention relates to Digital Governor for Diesel Engine field, particularly a kind of electronic governor actuator for diesel engine.
Background technology
Diesel engine is wide variety of dynamic power machine in national economy, and high performance diesel engine speed regulator is in various works
Improve diesel powered performance, economic performance and discharge performance under condition, have great importance for energy-saving and emission-reduction.Diesel engine is adjusted
The effect of fast device is to automatically regulate fuel delivery according to different load variations, due to diesel injection pump per fuel delivery per cycle with
The position of injection pump ratch is relevant with the rotating speed of oil pump, it is ensured that rational fuel delivery is it is necessary in certain accelerator pedal corner
Under rotating speed, the ratch position of reasonable control oil pump.With the development of electron controls technology, adjusted in various mechanical, fluid pressure types
On the basis of fast device, various types of electron speed regulators are generated, electron speed regulator can not only reach the function of mechanical governor,
And performance is better than mechanical speed governor, the dynamic property and discharge performance of diesel engine can effectively improve.
The content of the invention
It is an object of the invention to：For existing speed regulator idling oil mass is larger, fuel delivery fluctuation is big, hypervelocity stops supplying slowly
Deficiency, propose that one kind is based on monolithic processor controlled Digital Governor for Diesel Engine, the fuel oil that can effectively save under idling operation disappears
Consumption, and the noxious emission of idling operation can be effectively reduced, speed regulator can realize idling oil mass is smaller, fuel delivery fluctuation is small,
Hypervelocity stops supplying fast performance, has the characteristics of cost is low, simple in construction, available for all types of diesel engines.
Technical scheme provided by the invention is：A kind of electronic governor actuator for diesel engine, passed by 1 camshaft, 2 rotating speeds
Oily control-rod, 8 thread transmissions, 9 steps are stopped in sensor, 3 leverages, 4 oil pump cases, 5 oil pump ratch, 6 displacement transducers, 7
Stepper motor, 10 drive screws composition.Camshaft is connected with speed probe, and oil pump ratch is connected with displacement transducer, Lever machine
Structure is connected with oil pump ratch, and stepper motor is connected by drive screw with thread transmission and leverage.
The present invention has the prominent advantages that：The motion of driving stepper motor injection pump rack is controlled to adjust oil spout by single-chip microcomputer
Amount, and then diesel engine speed is controlled, the hardware configuration and control algolithm using single-chip microcomputer as core are taken, is become according to different loads
Change automatically regulates fuel delivery, the ratch position of reasonable control oil pump, speed regulator is realized that idling oil mass is smaller, fuel delivery ripple
Dynamic small, hypervelocity stops supplying fast performance, has the characteristics of cost is low, simple in construction.
Brief description of the drawings
Fig. 1 electronic governors perform structure chart
Embodiment
Technical scheme is described further below by way of accompanying drawing.
A kind of electronic governor actuator for diesel engine, by 1 camshaft, 2 speed probes, 3 leverages, 4 oil pump casings
Oily control-rod, 8 thread transmissions, 9 stepper motors, 10 drive screws composition are stopped in body, 5 oil pump ratch, 6 displacement transducers, 7.
Camshaft is connected with speed probe, and oil pump ratch is connected with displacement transducer, and leverage is connected with oil pump ratch, stepping electricity
Machine is connected by drive screw with thread transmission and leverage.
The motion of driving stepper motor injection pump rack is controlled to adjust distributive value by single-chip microcomputer, and then controls diesel engine to turn
Speed, takes hardware configuration and control algolithm using single-chip microcomputer as core, and fuel delivery is automatically regulated according to different load variations,
The ratch position of reasonable control oil pump, speed regulator is set to realize that idling oil mass is smaller, fuel delivery fluctuation is small, hypervelocity stops supplying fast property
Can, there is the characteristics of cost is low, simple in construction.
