Abstract
A slow-started speed controller comprises a power supply, an actuator, an electron speed regulator and a speed sensor, wherein the power supply end of the power supply is connected to the power supply end of the electron speed regulator; the electron speed regulator receives a speed signal from the speed sensor; and the electron speed regulator is provided with an accelerator control end connected to the actuator. When the engine is started, the accelerator is automatically controlled to slowly open and slowly supply oil so as to gently accelerate the engine, therefore preventing the smoke pollution caused by insufficient oil inflame and saving the oil consumption when starting the engine.
Description
Technical field
The present invention relates to speed regulator, especially a kind of slow startup speed regulator that is applicable to generator system.
Background technique
Need to start diesel generator and carry out work, at first to open switch, connect the instrument box power supply, then press " startup " pushbutton enable motor, operate in idling operation (575 ~ 650 rev/mins of rotating speeds) after engine start, subsequently, switch is pulled to the " RUN " shelves from " idling ", after now the final controlling element on fuel pump is received signal, control accelerator open degree rapidly from the minimum to the maximum, be increased to immediately the full throttle position from minimum throttle at idle position, engine speed also is raised to the high altitude vehicle rotating speed in 1530 rev/mins of left and right from idling rapidly, after bringing onto load, rotating speed is 1500 rev/mins of rated speeds.
But existing diesel generator carries out work, switch is pulled to the " RUN " shelves from " idling ", throttle increases to rapidly standard-sized sheet, fuel delivery is far longer than the oil mass that engine accelerating course needs, cause great amount of fuel oil fully not burn, cause the excessive over-emitting black exhaust of Acceleration of starting process smoke intensity, some motors also there will be the situation that Dark smoke billows in winter, this had both wasted fuel oil, more not environmental protection.
Summary of the invention
The invention provides a kind of fuel-efficient slow startup speed regulator of environmental protection while being beneficial to engine start.
For achieving the above object, the present invention explains a kind of slow startup speed regulator, comprise power supply and final controlling element, its key is: also comprise electronic speed regulator and speed probe, the power end of described power supply is connected with the power end of described electronic speed regulator, described electronic speed regulator receives the tach signal of described speed probe, and described electronic speed regulator is provided with the Throttle Opening Control end and is connected with described final controlling element, in described electronic speed regulator, is provided with:
For the device started;
The device of port is set for read latch; The user can arrange delay time by the time delay port according to demand.
For judging the judgment means whether motor starts; Speed probe is used for receiving the tach signal of motor, and engine rotational speed signal is transferred to electronic speed regulator, by the rotating speed of electronic speed regulator calculation engine.
If motor is not activated, return to the described device for judging whether motor starts;
If engine start, enter for the device to the zero setting of described electronic speed regulator Throttle Opening Control end output voltage; Electronic speed regulator can, according to engine speed, be controlled Throttle Opening Control end output voltage, if the judgement motor is starting state, in the present invention, starting motor rear engine rotating speed reaches 100 ~ 150 rev/mins, engine rotation, now, electronic speed regulator Throttle Opening Control end output voltage is 0 volt.
Device for the first time delay timing; The time delay timing is the endurance that electronic speed regulator Throttle Opening Control end output voltage is 0 volt.
For judging that time delay is to reach the judgment means of 0.1 second; Electronic speed regulator Throttle Opening Control end output voltage is 0 volt, and 0.1 second of time delay.
If time delay does not reach 0.1 second, return to the described device for the first time delay timing;
If time delay reaches 0.1 second, enter for described electronic speed regulator Throttle Opening Control end output voltage is increased to the device of 0.1 volt;
Device for the second time delay timing; The endurance that the time delay timing is electronic speed regulator Throttle Opening Control end output voltage V=V+0.1 volt.
For judging whether time delay arrives the judgment means of 10 milliseconds;
If time delay does not reach 10 milliseconds, return to the described device for the second time delay timing;
If time delay reaches 10 milliseconds, enter for reading the device of described signals of rotational speed sensor; Speed probe constantly is transferred to electronic speed regulator by the rotary speed information of motor, by the rotating speed of electronic speed regulator calculation engine.
For judging whether engine speed reaches the device of 250 rev/mins; Engine speed reaches and surpasses 250 rev/mins, and electronic speed regulator i.e. definite the beginning to engine oil, and electronic speed regulator Throttle Opening Control end output voltage actuate actuators, by the aperture of final controlling element control engine throttle.
If engine speed does not reach 250 rev/mins, return described for described electronic speed regulator Throttle Opening Control end output voltage is increased to the device of 0.1 volt; Motor starts to provide power by storage battery, when engine speed reaches 250 rev/mins, final controlling element is to work under existing electronic speed regulator Throttle Opening Control end output voltage drives, and can not the aperture of controlling throttle since 0, this is beneficial to the reasonable fuel feeding of motor, makes engine start steady.
If engine speed reaches 250 rev/mins, enter the device for read latch; Delay time arranges for the user.
For described electronic speed regulator Throttle Opening Control end output voltage is increased to the device of 0.1 volt; Electronic speed regulator Throttle Opening Control end output voltage increases with the amplitude of V=V+0.1 volt, control final controlling element and increase slowly accelerator open degree, increase slowly fuel feeding, thereby realize the acceleration that motor is mild, and avoid the insufficient pollutions such as black smoke that cause of oil inflame, more can save fuel consume when starting.
For judging whether described electronic speed regulator Throttle Opening Control end output voltage outputs to peaked device;
If described electronic speed regulator Throttle Opening Control end output voltage does not reach maximum value, return to the described device for read latch;
If described electronic speed regulator Throttle Opening Control end output voltage reaches maximum value, enter the device for completing.It is maximum that voltage reaches, and final controlling element is controlled throttle and reached maximum opening.
Remarkable result: during ato unit, control increases accelerator open degree slowly automatically, increases slowly fuel feeding, thereby realizes the acceleration that motor is mild, and avoid the insufficient pollutions such as black smoke that cause of oil inflame, more can save fuel consume when starting.
