Description

A kind of speed regulation device of diesel engine

Technical field:

The utility model relates to a kind of arrangements for speed regulation, relates in particular to a kind of speed regulation device of diesel engine.

Background technique:

Existing diesel engine generally adopts mechanical speed governor, adjusts the rotating speed and the fuel delivery of motor, and the adjustment reaction of mechanical speed governor is slower, so the decline of the rotating speed of motor is bigger when adjusting, causes easily and suppresses car, and fuel consume is excessive.

The model utility content:

But being to overcome the deficiency of above-mentioned prior art, the purpose of this utility model provide a kind of automatically controlled engine oil sprayer to reach the speed regulation device of diesel engine of optimum oil feeding, saving fuel oil, lifting power.

The purpose of this utility model can reach by following measure: a kind of speed regulation device of diesel engine, it is characterized in that it has electronic controller, electronic controller connects speed probe, automatically controlled speed regulator and rotating speed by lead respectively and adjusts switch, automatically controlled speed regulator has upper shell, lower shell body, the upper end that connects live axle in the upper shell by bearing, the bottom of live axle connects lower shell body by bearing, live axle connects electromagnetic core outward in the lower shell body, and electromagnetic core is provided with skeleton and drive coil outward.

In order further to realize the purpose of this utility model, described electronic controller has electronic control unit, interface unit, power supply unit, electronic control unit is adjusted switch with speed probe, automatically controlled speed regulator and rotating speed respectively by 3 interfaces (JP1, JP2, JP3) of interface unit and is linked to each other, and power supply unit provides electric energy for electronic control unit, interface unit.

The utility model can produce following good effect compared with the prior art: the utility model can be worked as engine load and be strengthened, when engine speed descends, improve the rated speed that fuel delivery is kept motor rapidly, when engine load reduces, when engine speed raises, reduce the rated speed that fuel delivery is kept motor rapidly, size by the speed perception load, the accurate throttle of adjusting is saved fuel oil 15～25% to the optimum position thereby reach, and promotes power 10～20%.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional view of the automatically controlled speed regulator of Fig. 1;

Fig. 3 is an electric theory diagram of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:

Embodiment: a kind of speed regulation device of diesel engine is (referring to Fig. 1-Fig. 3), it has electronic controller 1, electronic controller 1 connects speed probe 3, automatically controlled speed regulator 4 and rotating speed by lead respectively and adjusts switch 2, electronic controller 1 has electronic control unit 1-1, interface unit 1-2, power supply unit 1-3, electronic control unit 1-1 adjusts switch 2 with speed probe 3, automatically controlled speed regulator 4 and rotating speed respectively by 3 interfaces (JP1, JP2, JP3) of interface unit 1-2 and links to each other, and power supply unit 1-3 provides electric energy for electronic control unit 1-1, interface unit 1-2.Automatically controlled speed regulator 4 has upper shell 4-1, lower shell body 4-3, the upper end that connects live axle 4-2 in the upper shell 4-1 by bearing, the bottom of live axle 4-2 connects lower shell body 4-3 by bearing, live axle 4-2 connects electromagnetic core 4-4 outward in the lower shell body 4-3, and electromagnetic core 4-4 is provided with skeleton 4-6 and drive coil 4-5 outward.

During use, the lower end of live axle 4-2 connects the oil mass regulating lever of the Injection Pump of diesel engine, behind the ato unit, adjust rotating speed and adjust the rated speed of switch 2 to motor, rotating speed is adjusted switch 2 and is sent the rated speed signal to electronic control unit 1-1, electronic control unit 1-1 sends the drive coil 4-5 of command signal to automatically controlled speed regulator 4, drive coil 4-5 task driven electromagnetic core 4-4 drives live axle 4-2 and does reciprocating linear motion, promote oil mass regulating lever control fuel delivery, make engine control arrive rated speed.When engine load strengthens, when engine speed descends, speed probe 3 perception present engine rotating speeds descend, adjust the drive coil 4-5 of electric current to automatically controlled speed regulator 4 by electronic control unit 1-1 output rapidly, live axle 4-2 promotes the oil mass regulating lever and improves the rated speed that fuel delivery is kept motor.Otherwise, when engine load reduces, when engine speed raises, speed probe 3 perception present engine rotating speeds raise, adjust the drive coil 4-5 of electric current to automatically controlled speed regulator 4 by electronic control unit 1-1 output rapidly, live axle 4-2 promotes the oil mass regulating lever and reduces the rated speed that fuel delivery is kept motor rapidly.
