Description
Technical field
The invention belongs to automobile cooling system field, a kind of engine-cooling system is specifically referred to.
Background technology
More and more harsh standard is promulgated in oil consumption of the national governments to engine, such as specified in the year two thousand twenty requirement vehicle main frame
Factory persistently reduces oil consumption to 5.0L/100km；Fuel-economizing has become the development trend of world car, and most important in fuel-saving measures
A technology be exactly engine supercharging miniaturization+Technology of Hybrid Electric Vehicle.
In response to the regulation of local government, it is necessary to find a kind of Engine Matching system more innovated to complete this
Target.Because on the premise of dynamic property is not lost, wanting that decline 30% substantially one can not on the basis of at present oil consumption
Completing for task.Therefore propose that face, using hybrid power system+electronics supercharging, is increased by weak mixed and engine on the engine
Pressure miniaturization, being reached with this reduces the requirement of oil consumption.Because whole system matches extremely complex, corresponding vehicle cooling system
System design also tends to complexity.
Conventional engines cooling system, when engine works, the heat that fuel oil burning is produced is except acting, heat radiation, biography
Lead waste gas to take away outward, remaining is cooled down by cooling system.Whole cooling circulation is divided into two states：Thermostat is closed
Closed state and thermostat opening, and thus it is divided into systemic circulation and partial circulating.
Engine is in and just starts working condition, and water temperature does not rise up also, and now, thermostat is closed, hair
Motivation is in partial circulating state；As water temperature gradually rises, the cured bag expanded by heating inside thermostat, thermostat is gradually opened,
The loop for connecting radiator is opened, and then enters systemic circulation.
Prior art the disadvantage is that, under the engine systemic circulation state of cooling, only one major loop.With engine section
The continuous popularization of oil tech, integrated amount of parts gradually increases on engine, such as charge air cooler, BSG, turbocharger, electricity
Sub- water pump etc., these new integrated parts need also exist for being cooled down, but, chilling temperature, flow required for it with
And control logic is completely different with engine cylinder-body, cylinder cap；In addition, with the application of start-stop technology, such as Ricardo Inc. etc.
The HyBoost engines of exploitation have quick start-stop function, simple to rely on switching regulator mechanical water pump to reduce engine consumption level
The heating demands after engine is shut down cannot be met, especially in temperature lower ground area, this defect is especially prominent.Therefore,
Traditional Cooling System Control Circuit can not meet the application of new technology.
In addition, cylinder body is also different from the cooling requirement of cylinder cap, cylinder body water temperature is optimally maintained at 95 DEG C -105 DEG C, can maintain
Machine oil reduces frictional work, so as to reduce the oil consumption level of engine in relatively low viscosity；Cylinder cap water temperature is optimally maintained at 85 DEG C of left sides
The right side, can improve intake efficiency, so as to improve the dynamic property of engine.But current cooling system cylinder block and head coolant stream
Amount is identical, and temperature is essentially identical, so the economical and dynamic property of engine can not be taken into account.
Again, engine with supercharger pinking is currently the most thorny technical barrier of domestic and international automobile industry, one of reason
It is too high or unstable intake air temperature.At present, in water-cooled cold mode better than cold mode in air-cooled, but the water inlet of water-cooled charge air cooler
(coolant) temperature can directly affect the intake air temperature of engine.The intake air temperature of engine generally require control 60 DEG C with
Under, can otherwise cause combustion knock or cause ECU that (measure of limitation moment of torsion) is turned round to the limit of transmitter, therefore the cooling of charge air cooler is followed
Ring typically can individually arrange low-temperature circulating.And low-temperature circulating coolant temperature have to be lower than 55 DEG C, preferably lower than 50 DEG C, but it is actual
Under upper many operating modes, the inflow temperature of charge air cooler exceedes above-mentioned limit value (55 or 50 DEG C).One of reason for that is followed for low temperature
Although ring and high temperature circulation have single radiator, but share an expansion tank, cause the high temperature coolant in expansion tank
Into low-temperature circulating, the inflow temperature of charge air cooler is influenceed, reason is：(1) charge air cooler enters cold radiating during coolant comes from
Device and expansion tank, although the flow of expansion tank is smaller, but cold heat sink temperature in coolant temperature ratio in expansion tank
Degree is typically higher by more than 50 DEG C, reaches as high as 100 DEG C；(2) water pump of low-temperature circulating is electronic water pump, and changed power is big, change
Speed is fast, causes the moisturizing bypass flow of expansion tank extremely unstable, therefore the moisturizing of expansion tank is charge air cooler inflow temperature
Main cause high and unstable.
Finally, traditional mechanical thermostat response is slow, opens, closes by the water temperature decision of engine, is unfavorable for
The quick cooling of the warming-up and water temperature of engine.
With water-cooled relatively, also exist to enter charge air cooler, BSG, turbocharger by the way of air-cooled in the prior art
The technical scheme of row cooling, but this air cooling way space requirement is high, and the arrangement to whole enging cabin has higher requirements, arrangement
Difficulty is big, and thermal balance risk is big, generally requires to be iteratively improved and can be only achieved ideal effect.Other vehicle use environment is changeable, makes
Air cooling system is obtained to be difficult to meet the demand of each operating mode of various use environments；In addition, with the application of start-stop technology, mechanical water pump without
Method meets the heating demands after engine is shut down, and especially in temperature lower ground area, this defect is especially prominent.
Cylinder cover water jacket design is influenceed by combustion chamber, air flue space, the influence of casting technique, and cylinder cover water jacket structure can not
Ensure the equilibrium of coolant rate in whose set, but because the combustion characteristics of internal combustion engine can form a temperature in cylinder cover water jacket end
Peak (because coolant is bad in circulation herein, easily assemble, and water temperature is higher than engine water outlet water temperature by 5 herein by temperature
DEG C or so).In pole bad working environments such as climbings, cylinder cap end part water temperature can rapidly rise, 17 DEG C higher than delivery port water temperature or so.
At this time the actual water temperature experienced of electronic thermostat wax bag is the water temperature of engine water outlet, so that can not be normally-open, no
Cooling system heat dissipation capacity can in time be increased, cause thermal balance unstable and exceeded.
