Description
Technical field
The present invention relates to diesel engine start-up technique field, more particularly, to can be automatically quick at low temperature
Start the system and method for high output diesel engine.
Background technology
Military vehicle is one of my army's equipment foundation ground mobile equipment that quantity is many, range is wide,
Extremely important effect is played in the operational support of my army and logistics support.In Future Information battlefield,
For completing to win the combat mission of the local war under Information Condition, the mobility of my army's military vehicle,
The level of IT application and protection require more and more higher.
Accumulator is the indispensable vitals of military vehicle, is the heart of military vehicle electrical system,
It is the assembly parts of my army's military vehicle severe cold area mobility of restriction and general-purpose support performance
In short slab.
The military vehicle plumbic acid cold-starting using at present starts battery, in China northeast and In The North of Xinjiang -30
DEG C to -50 DEG C of harsh climate area, discharge performance drastically declines, and leads to military vehicle cannot open normal starting
Dynamic.Generally military version starting startup lead acid accumulator pole low temperature (- 41 DEG C) flash-over characteristic is proposed higher
Requirement, but the structural physical feature due to lead-acid accumulator, determine the total capacity of output under its low temperature
It is greatly reduced with the persistent period of high power discharge it is difficult to meet the use requirement of military vehicle and low temperature.
Specifically, using the problem that lead-acid battery carries out cold-starting it is at present：
1) under lead-acid battery low temperature, performance degradation is fast, and 3 multiplying powers (3C) discharge time of its interval will not surpass
Spend 3 minutes (30 seconds electric discharges, 60 seconds resting cycles), the 15% of only nominal electricity；If 3 multiplying powers
Continuous discharge, discharge time not over 2 minutes, the 10% of only nominal electricity；
2) start under low temperature, vehicle is that very difficult once dragging just starts successfully, and dragging number of times is more, sends out
The resistance of dynamic system is less, and vehicle more possesses entry condition, but it is that lead-acid battery drags for the first time
Energetically, just weaker for the second time, third time is actually difficult to continuous and effective and drags.Therefore, plumbic acid electricity
Performance on dragging for the output in pond, and the demand of electromotor is contrary；
3) under low temperature start vehicle, battery drag when output voltage and electric current be impact starts successfully and
One of no many factors, the factor of intake air temperature, center housing temperature, oil temperature etc. is also very
Important.Lead-acid battery because under low temperature possible capacity little it is impossible to provide enough energy to carry out air inlet,
The heating operation of machine oil etc. it is therefore necessary to need to be carried out by measures such as blowtorch heating, ether injections must
Starting of wanting is preheating, or is starting to be that warm-up phase uses the offer of other set lead-acid battery limited
Energy, this can cause vehicle structure complexity, complex operation it is clear that can bungle the chance of winning a battle in modernized war.
Under haveing no alternative but, the method for current vehicle user heating and thermal insulation also to be adopted, improve military plumbic acid and store
The cryogenic discharging characteristic of battery, and these heating and thermal insulation measures attachment device generally to be increased and consuming are longer
Time is realized, and affects emergent battle mobility and the protection of military vehicle.
In addition during normal use lead-acid accumulator there is problems：Protect poor electrical performance, short term storage
Battery is by automatic discharging；Short life, in the life cycle management of military vehicle, needs replacing to scrap several piece electricity
Pond；It is frequently necessary to maintaining.
Therefore it is badly in need of exploring developing the military vehicle novel battery substituting lead-acid battery, thoroughly solve army
The various problems with cold-starting difficulty in starting as conspicuous contradiction brought using lead-acid battery with vehicle, are carried
The motor-driven and guarantee performance of high military vehicle.
Conventional lithium ion battery instead of lead-acid battery and other system batteries in numerous civil areas,
From the point of view of mesh new progress, in rechargeable battery (secondary cell) field, lithium ion battery is still
2025 are before, mostly important, can large-scale application secondary cell system.Since two thousand, generation
The cumulative investment of various countries of boundary, more than 10,000,000,000 dollars of reasearch funds, is wherein confined to portable electronic mostly
Equipment and electric automobiles, the big multiplying power at -20 DEG C can't being solved the problems, such as so far, its product is in -41 DEG C of bars
Safety under part and low temperature performance even more cannot ensure.
Under cryogenic conditions, especially extremely cold at -41 DEG C under the conditions of cold start-up problem, always puzzlement focuses on
Type vehicle high-power (more than 380kw), a great problem of diesel engine.Due to the impact of low ambient temperature,
Engine lubrication oil viscosity increases, and each friction surface cannot get sufficient pre-lubrication, thus increase starting
(heavy vehicle electromotor rear portion carries load, such as hydraulic mechanical transmission box etc. to the resistance of start of machine, makes to open
Dynamic resistance increases further), cause engine start rotating ratio room temperature to be decreased obviously, leakage of compressed gas increases
Many, gas is longer to the heat transfer time of cylinder wall, and thermal loss is larger, makes the air themperature that compression ends
With reduced pressure；The viscosity of diesel oil and density all become big, atomizing effect be deteriorated, the air themperature in cylinder with
Insufficient pressure causes diesel engine starting difficult；Battery liquid viscosity increases, to the penetrating power of pole plate
Decline, internal resistance increases, during cold-starting, accumulator output declines, and leads to starter motor powerless dragging bavin
Oil machine rotates or can not reach minimum startup rotating speed.
At present, the supporting flame air inlet heating device of high-power air-cooled diesel engine is only capable of meeting -20 DEG C of low temperature
Cold start-up requires, less than -20 DEG C even more cold extremely cold under the conditions of, the cold start-up that only carries by electromotor
Device, is difficult to smoothly start vehicle.For solving the high-power air-cooled diesel of heavy vehicle under the conditions of extremely trembling with fear
It is necessary in addition install cold start-up ancillary method additional for vehicle, such as filling starts liquid, cooling to machine cold start-up problem
Medium heating, lubricating oil heating, low-temperature storage battery and accumulator cell heat preserving etc., though test shows above-mentioned measure
So can significantly improve high-power diesel engine cold-starting effect to a certain extent, but all there is startup
Time longer shortcoming it is impossible to meet electromotor quick needs starting in -41 DEG C of low temperature, or even
Individual other measure (as filling starts liquid) is larger to engine damage, there is potential safety hazard simultaneously.
In addition, the diesel oil boiler pre-heating system of high-power water-cooling matched with diesel engine only can be to engine body
Carry out preheating, engine charge cannot be preheated, ambient temperature (intake air temperature) be -41 DEG C with
It is impossible to successfully start up vehicle when lower.And, preheating at low temperature takes longer (being one hour),
The requirement of quick startup cannot be met.
Content of the invention
In view of this, the present inventor is made that the present invention.The technical problem to be solved in the present invention is,
