Abstract
Be contained in the controlling method of construction engineering with the motor in the vehicle, the step that comprises has: reduce engine revolution to first revolution, this revolution approaches after all operating handles relevant with whole control valves of starting of car body turning workpiece and vehicle take-offs etc. move on to their neutral gear position, the rated revolution of the motor when carrying out the ground move operation immediately, motor is remained on the next predetermined time cycle of this low-speed running condition, further engine revolution is reduced on the second low revolution then, this revolution is corresponding with idle running revolution down, thereby realizes reducing fuel consumption and by the noise level of motor generation.
Description
This invention relates to and is contained in the controlling method of construction engineering with the internal-combustion engine on the vehicle, has low fuel consumption during this vehicle take-offs, and the noise that motor produces has than low level.
Use in the vehicle in the construction engineering that internal-combustion engine (being designated hereinafter simply as " motor ") is arranged, the oil hydraulic pump that the engine-driving discharge capacity is variable, so that start to work device, and the flow rate that is used for controlling the liquid that oil hydraulic pump discharges, when the fluid flow that oil hydraulic pump is flowed out when vehicle does not require, finish this configuration with regard to a kind of in available following three kinds of modes.
1, motor is not controlled, that is to say, on the same value the when revolution of motor remains on almost and to require the flow of output liquid with oil hydraulic pump.
2, directly control is ejected into in-engine total amount of fuel, so that reduce the revolution of motor.
3, rise when become the unnecessary moment by oil hydraulic pump trickle amount, experience a predetermined time cycle after, the total amount of fuel that is ejected into motor is controlled, thereby reduces the revolution of motor.
Each of above mentioned three kinds of methods has following shortcoming respectively.
Briefly, under the situation of first kind of controlling method, motor is in fast state, even also is so when the fluid flow that need do not flowed out by oil hydraulic pump, so fuel waste, and the noise of motor generation is very big.
And second kind of controlling method is suitable for use in the All Time of construction engineering with the ground mobile working of vehicle, but under this method situation, when the ground mobile working is continuous, and when requiring to be interrupted the feed fluid flow by oil hydraulic pump, engine rotary speed changes continually not only to motor generation adverse influence, and because the variation of the noise that motor produces, also making to drive has unsatisfied sensation.In addition, the power that is produced by hydraulic pressure causes that surging phenomenon appears in motor, and this phenomenon result breaks down component.
Under the situation of the third controlling method, the revolution that does not reduce motor up to the fluid flow that oil hydraulic pump flows out become do not need after, experience pre-determining the time cycle again.So, the numerical value when engine revolution begins to be kept above proper functioning, high amount corresponding to the carrying capacity that reduces on the motor, fuel is consumed as a result, and the noise that motor produces also becomes higher.In addition, owing to experienced after the predetermined time, the revolution of motor so probably makes motor unwanted low speed rotation occur by reducing to low speed at a high speed.Therefore, doing under the mobile working situation of ground, requiring is providing the output liquid flow above in the above-mentioned scheduled time discontinuously by oil hydraulic pump, requires for some time, changes to desired high speed rotating from low speed rotation.Cause inferior operability and low working efficiency like this.
The present invention is by above-mentioned design of prior art situation viewpoint and design, its objective is provides a kind of to being contained in the method that construction engineering is controlled with the motor on the vehicle, this method comprises some steps: be about to engine speed reduce to all operating stem move to respectively they separately under the neutral position after, near the rated engine speed when carrying out the ground move operation immediately lower-speed state, motor is remained on the cycle that this next section of low-speed running state pre-determines the time, therefore engine speed is further reduced to desired low speed (idling speed) condition, can reduce fuel consumption with this understanding, and the noise of the few motor generation of rate.
To achieve these goals, according to the present invention, will provide a kind of controlling method with the motor on the vehicle to being contained in construction engineering, it is characterized in that when all operating handles of workpiece and operation system are in their neutral position, the revolution of motor is reduced on the slow speed of the first order at once, a predetermined time, motor is remained on this revolution.Then, further reduce on the low revolution in the second level.
