Cause), and engine oil quality can be influenceed, make the friction surface of each parts of engine be not easy to form and keep oil film, cause to lead
Gallery pressure can not be established, so as to aggravate the abrasion of parts.Because influence of the water temperature to oil pressure must could be realized by oil temperature,
Therefore with certain indirect, it is necessary to the regular hour.
(2) when needing to make machine oil heat up, because the heating of machine oil is more slow, the actual temperature of machine oil is caused less than reason
Think temperature.Now, oil body becomes big, causes poor fluidity；The frictional resistance of moving parts also accordingly increases, and causes oil
Consumption increase.
(3) after motor vehicles travel longer than tens of thousands of kilometers, cylinder and piston, piston ring and annular groove, the gas of engine
Existing gap can cause gap size to become big after by lasting friction between door and valve seating.When the size in gap
After becoming big, the engine oil pressure flowed through will certainly reduce, and this reduces the effect of lubrication, and the abrasion after causing will be tighter

Main oil gallery communicates；Inclined ellipse shape hole communicates with oil cooler.By the change of oil circuit, and install a temperature control valve additional,
Can controls the trend of machine oil according to oil temperature.When oil temperature is relatively low, the obstructed subcooler of machine oil, is directly entered main oil gallery；And
When oil temperature is higher, machine oil is introduced into cooler cooling, subsequently into main oil gallery.However, this control system is set due to needing
Pipeline adds oil circuit to be heated up, therefore its cost is relatively higher.Although in addition, the control system solves cold start-up machine oil

Need exist for illustrating, three temperature above-mentioned, i.e.,：40 DEG C, 100 DEG C and 120 DEG C, be the hair of the application
What a person of good sense finally determined by many experiments.Experiment proves：When oil temperature is below 40 DEG C, oil consumption increase, engine mill
Damage larger；And when oil temperature reaches 40 DEG C, engine oil viscosity reaches 10, and now oil consumption and abrasion are not very big.Engine warm
When machine operates, the mean temperature of machine oil is ideal nearby at 100 DEG C；And when oil temperature is more than 120 DEG C, machine oil oil film is not
It can be formed, lead to not be lubricated, engine damage is also resulted in if serious, it is therefore desirable to which oil temperature control exists
Less than 120 DEG C.
The technique effect that above three step obtained will be illustrated by experimental data below：
First, step (i) aims to solve the problem that problem present in low temperature and cold start.
At present, lack of lubrication when 75% abrasion derives from cold start in automobile engine, because low temperature viscosity is 10
Neighbouring machine oil just has the lubrication of real meaning, and the time before reaching viscosity 10 is more long, and the abrasion of engine is got over
Greatly.In order to reduce abrasion, can only consider to shorten the time before low temperature arrival 10.
Using the step (i) in the inventive method, in low-temperature cool starting, heating wire can be utilized to connect to being arranged on machine filter
Heating membrane on the annular inner wall of joint chair is heated, so that machine oil is warming up to 40 DEG C.
Refer to Fig. 6, it can be seen that step (i) offers the advantage that：
(a) above method is utilized, engine oil viscosity is minimized, and is thereby reduced the abrasion of engine components, is extended this
The service life of a little parts.
(b) oil consumption reduces.
(c) vehicle riding comfort improves, and noise reduces.
Second, step (ii) aims to solve the problem that the problem of wearing change aspect.
Under warming-up operating mode, the oil temperature in crankcase is designed near 100 DEG C.Therefore, 100 DEG C of engine oil viscosity shows
It is so the core index of oil lubricating performance.It is each to engine at the beginning of engine is designed that this depends primarily on engine designer
The gap designed between individual component.But vehicle may use the machine oil of different model, Huo Zhesui in actual use
The abrasion of engine, each pack clearance of engine becomes big.Now, the most suitable engine oil viscosity designed originally can become
Change, will certainly influence engine oil pressure after viscosity B coefficent.
Using the step (ii) in the inventive method, when oil temperature is near 100 DEG C, engine oil pressure changes
Afterwards, system can adjust heating or cooling.If engine oil pressure becomes big, appropriate heating, increase engine oil flow；If machine oil
Pressure diminishes, then appropriate cooling, increases engine oil viscosity, allows pressure to recover initial design values.
Refer to Fig. 7, it can be seen that step (ii) offers the advantage that：
(a) prevent engine oil pressure from becoming big, carbon distribution increase after burn oil becomes more, reduce dynamic property.
(b) oil consumption is reduced.
(c) discharge gas is optimized.
3rd, the problem of step (iii) is aimed to solve the problem that in terms of high temperature dry friction.
In external high temperature, and driver, for a long time in the case of leaf fat, oil temperature can be raised further, its viscosity
Greasy property of the machine oil in the lubrication key position warm-up mode such as maneton, camshaft can be expressed.If oil temperature is higher than 120
DEG C, when oil film temperature is up to more than 150 DEG C, that is, it is easily broken to form semi-dry friction.Because crankshaft bearing is Pot metal, if
Cooling measure is improper, will make Bearing Temperature and separate out the fusing of its lead, then consequence is hardly imaginable.
Using the step (iii) in the inventive method, when system detectio to oil temperature reaches 120 DEG C, system is by valve
Door is opened, so that oil temperature is reduced to 100 DEG C or so.
Refer to Fig. 8, it can be seen that step (iii) offers the advantage that：
(a) engine breakage, scuffing of cylinder bore are avoided.
(b) oil consumption, discharge gas are reduced.
(c) pinking is avoided to a certain extent.
Although the structure and operation principle of the present invention are illustrated above in association with preferred embodiment, this technology
Those of ordinary skill in field is it should be appreciated that above-mentioned example is intended merely to explanation, and cannot function as the limit to the present invention
System.Therefore, the present invention can be modified in the spirit of claims and modification, these modifications and variations
