Embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical scheme will be carried out below
Detailed description.Obviously, described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all on the premise of creative work is not made
Other embodiment, belongs to the scope that the present invention is protected.
Embodiment one
A kind of engine intelligent cleaning curing system as shown in Figure 1, including the detergent line being connected with engine, and
Detergent line is connected with engine interior, wherein, detergent line is equipped with：For the old oily filter core of impurity screening, and can
Drive the oil pump of engine oil flow in detergent line；Detergent line is connected with the air inlet port that can increase air pressure, and one kind starts wisdom
Curing system can be cleaned and be additionally provided with the dielectric constant detector that can detect old oil quality, dielectric constant detector can be used in examining
Survey old oily quality.
During using cleaning systems described in the present embodiment, cleaning oil is added after old oil is emptied, is opened by engine itself
Open or oil pump provide power so that cleaning oil flows to detergent line after engine interior is rinsed, further through old oily filter core
Filtering flow into engine interior again, repeat above-mentioned movement so that cleaning oil forms admonitory talk to subordinates in engine and detergent line,
After a certain period of time, discharge with impurity cleaning oil, supplement new lubricating oil, then ressembled engine components can be complete
Into.
Detergent line is equipped with three interfaces, respectively with the stifled K1 interfaces being connected of draining the oil, is connected with machine oil filter core base
K2 interfaces, K3 interfaces so that detergent line forms closed circuit chamber with engine interior.Wherein, K1 interfaces, K2 interfaces and old oil
Filter core is connected, and K3 interfaces are connected with oil pump.So so that institute's organic oil of interior conduit flowing can flow through filter core, and then played
Filter acts on.
Into to ensure that cleaning oil can be circulated through in detergent line, detergent line is equipped with the first solenoid valve and the second electromagnetism
Valve, wherein, K1 interfaces, K2 interfaces are connected by the first solenoid valve with old oily filter core, and the first solenoid valve control cleaning oil can only lead to
Cross K1 interfaces or K2 interfaces exit into detergent line.
Old oily filter core is connected with oil pump respectively by second solenoid valve, and K3 interfaces are connected.Fluid in detergent line can
Engine interior is flowed into by K3 interfaces, in static rinse, since engine need not be opened, is then needed by the second electromagnetism
Where valve opening oil pump all the way, offer power is moved for in-engine cleaning oil stream.
All cleaning oil for being flowed into engine interior all have to pass through the filtering of old oily filter core, and old oily filter core can filter
Fall the impurity from engine outflow, prevent impurity from coming back to engine interior again and causing secondary pollution, in some of the present invention
In embodiment, the strainer density of the filter core of engine installation is probably 30 microns, and the filter plant strainer that engine carries is close
Degree is only capable of reaching 5-10 microns, so old oily filter core can preferably filter out thinner impurity, there is preferably cleaning to imitate
Fruit.Preferably, old oily filter core is transparent filter core so that user and staff more intuitively can observe and grasp the shape cleaned
Condition.
Dielectric constant detector can understand the situation of the old machine oil of engine, even if some vehicles are not up in regulation traveling
Journey, since the lubricating oil inside external influence may not reach the standard of normal use；Some vehicles have reached regulation
Distance travelled, but in-engine lubricating oil can keep preferable state, then may not necessarily replace, so dielectric constant detects
Instrument is except that can achieve the purpose that promptly and accurately maintenance washes engine, moreover it is possible to save the expense of car owner to a certain extent, prevent
Only unnecessary waste.
Embodiment two
The present embodiment is described further based on the technical solution described in embodiment one.
As shown in Figure 1, a kind of engine intelligent cleaning curing system further includes housing 5, the interior pipeline is arranged on shell
In body 5, the dielectric constant detector is arranged on housing 5, in use, it is normal to drop in dielectric from the certain oil sample of engine absorption
It is detected above number detector, it is therefore intended that it can be detected before the beginning of washing and cleaning operation and judge old oily service life,
If remain to, in the state that can be used, to be lubricated the replacement of oil.
In other embodiments of the present invention, specific purpose tool can be first passed through from engine interior before maintenance is carried out maintenance
Extract and is carrying out the detection of Oil life with oil on a small quantity, if so tending to be normal with oily indices times, illustrating can also be after
Continuous to use, if showing that engine scuffing is excessive with the testing result of oil, pollution particle is excessive, then can enter more tightened up thin
The detection of cause, can extract a random sample oil and do further detection in lubricating oil laboratory, so as to judge the irregular wear of engine
Position, maintenance engine, is avoided engine from being brought the hidden danger of bigger due to early stage irregular wear, so not only prevented as early as possible
Major structure also saves the maintenance clean expense of car owner to a certain extent into unnecessary waste.
Lubricant life detection is exactly to be increased in use by constantly oxidation, pollutant by means of used-oil
It is more, and process, the dielectric constant of lubricating oil such as change of various acidification reactions can accordingly change, lubricating oil is a kind of multiple
Miscellaneous hydrocarbon mixture, can consider using it as a kind of dielectric.With the increase of lubricating oil validity period, its Performance Decay
It is mainly reflected in the following aspects：(1) with air contact oxidation reaction occurs for lubricating oil internal composition for a long time；(2) viscosity refers to
The additive losses such as number modifier, antioxidant, antiwear additive；(3) external contamination, including the pollution of water pollution, ethylene glycol, solid particle
Pollution etc..
Lubricating oil is aoxidized, additive losses can cause molecular polarity to change；Water produces H+, OH-ion into membership；Acid
The change of value is with H+, the generation of RCOO- ions；Metal worn particle can produce free electron.Several factors can be different above
Change to degree the quantity of fluid internal polarization component, so as to cause the change of dielectric constant values, so dielectric constant is reflection
Oil degradation, contaminated and wear condition a comprehensive parameters.
There are the dielectric constant detector of production correlation function, some of testing principles in domestic and international many factory commercial cities
It is as follows：(1) memory of sample oil zero point, the clean lubricating oil that will add equipment first are placed on oil quality detection instrument and are adjusted
Zero, zero point cleans up the oil in oil pocket after determining；(2) lower sensor is recorded as the numerical value on unloaded lower display to CPU,
Different types of clean oil, after the oil of oil pocket is cleaned up again after zeroed, display has different numerical value, will be all to be measured
After clean oil zeroing, the numerical value under corresponding zero load records oil one by one, and one by one in numbering deposit memory；(3) afterwards into
When row soiling value is tested or moisture rate is tested, tested oil product code entered from the keyboard, CPU calls sample oil data automatically, without again
