Temperature and change, and generally, lubricant be selected such that its at the typical operating temperature of engine will performance it is good.So
And for producing substantial amounts of hot engine such as explosive motor, generally, it is being increased to engine generation heat
Before typical operation temperature, engine will be started with environment temperature.Therefore, following periods in engine start be present：
During the period, in-engine lubricant is in below its optimum operating temperature.For this reason, it is often desirable to opened in engine
The part of such as piston and cylinder etc is allowed to warm up as quickly as possible when dynamic, to ensure the lubricating oil in piston as much as possible
Effectively.
However, also there is the risk to overheat in piston and cylinder.Especially, such as spark plug being contained at cylinder head
Generally easily it is susceptible to overheating with the part of sensing device further etc.Therefore, the cylinder in Modern Engine, which is provided with, is filled with
The shell or sheath of fluid --- being typically water ---.These water sheaths provide cooling, and reason is to come from piston and cylinder
Heat be only absorbed by the water.The water to warm, which is then pumped, to be left sheath and is replaced by colder water to absorb more heat.
However, during engine start, sheath is still filled with water, and therefore, sheath tends to absorb heat, so as to slow down
Piston and cylinder warm, and have therefore slowed down warming for lubricant, and reduce after engine start soon
Lubricant efficiency.In the case where allowing colder water to be flowed into during the period of warming in sheath, this effect can be worse.
It is therefore important that provide a kind of following water sheaths：The water sheath can be after explosive motor be started

In this way, following junction surfaces are provided with：In the junction surface, fluid can be advanced to easily from one-level conduit
In two level conduit, but in the junction surface, direction that the fluid advanced into three-level conduit is subjected to by fluid
Acute angle changes and bears larger resistance.Therefore, compared to the fluid for flowing through three-level conduit, more fluids will tend to flow
It is dynamic to pass through two level conduit.This species diversity can be based only upon shape and the relation of conduit to provide, without the valve system of complexity,
Complicated valve system is after repeated use it is possible that mechanical breakdown.Therefore, when fluid for example due to its just be pumped and
When flowing through junction surface under stress, compared to by by three-level conduit supply to second cooling sheath fluid, more
More fluids will tend to leak through two level conduit and be supplied to the first cooling sheath.In the case of every other factor identical, stream
The dynamic a greater amount of fluids for passing through the first cooling sheath will tend to the first cooling sheath and be absorbed more than the second cooling sheath
Heat.Therefore, in use, compared to the engine components being contained in the second cooling sheath, it is contained in the first cooling sheath

Fig. 1 is the schematic diagram according to the first cooling system of the present invention；
Fig. 2 and Fig. 3 show the second cooling system；
Fig. 4, Fig. 5 and Fig. 6 show the 3rd cooling system；And
Fig. 7 shows the 4th cooling system according to the present invention.
Embodiment
Fig. 1 shows the schematic diagram of the first cooling system 101 according to the present invention.Cooling system 101 is intended to drive with piston
Dynamic formula explosive motor (not shown) is used together, and cooling system 101 includes the first one-level conduit 102, the first two level is led
The three-level conduit 104 of pipe 103 and first, these three conduits connect all at junction surface 105.Fig. 1 shows the first cooling system
Substantially the same orientation is orientated in will be installed on vehicle with the first cooling system, wherein, the top of the schematic diagram
Represent those higher parts in position for gravity in the vehicle for being fitted with the first cooling system 101.
First two level conduit is additionally coupled to the first water sheath 106, and the first water sheath 106 is intended to around piston-cylinder lid (not
Show) it is equipped with and provides cooling for piston-cylinder lid.First water sheath 106 is provided with first-out part 107.
First three-level conduit 104 is additionally coupled to the second water sheath 108, and the second water sheath 108 is intended to around piston-cylinder
Advance the part (also having been not shown) passed through by piston head and be equipped with and provide cooling for this part.Second water sheath 108 is set
Second-out part 109 is equipped with, second-out part 109 includes valve 110.
In use, water edge is pumped by the direction shown in arrow 111 around the first cooling system 101 so that water will absorb
Waste heat from piston-cylinder and piston-cylinder lid.Water then marches to scattered via first-out part 107 and second-out part 109
Hot device, at radiator, water is allowed to be cooled down before being pumped through the first cooling system 101 again.This prevent
Piston-cylinder and piston-cylinder lid become heat to the degree for damaging the part accommodated in it.
However, when engine is colder --- this generally followed by the startup of engine and occur, it can be advantageous that make
Piston-cylinder is obtained to be quickly warmed up.Therefore, when engine is colder, valve 110 can be turned off to prevent water from passing through second-out part
109 flow out from the second water sheath 108.Therefore, the water in the second water sheath 108 will be tended to remain in the second water sheath 108.Stay in
Water in second water sheath 108 then absorbs the heat from piston-cylinder.This still reduces the speed that piston-cylinder warms up, but
It is due to that the water to warm is kept and is close to piston-cylinder, therefore piston-cylinder can faster underground heat rises than situation that valve 10 is opened
Come.
Generally, or even after starting, it is still necessary to water is pumped across into the first one-level conduit 102 and the first two level is led
The water of pipe 103 to the first sheath 106.This be due to cylinder head often very rapidly produce substantial amounts of heat and also accommodate easily by
The equipment for crossing heat affecting.
First three-level conduit 104 and the second water sheath 108 are designed to reduce the into and out second water sheath 108 of water
Siphon, and therefore by water, --- particularly warmer water --- is more efficiently stayed in the second water sheath 108.
First, the first three-level conduit 104 by with the first one-level conduit 102 it is at an acute angle in a manner of be connected to junction surface 105.Cause
This, is through the current of the first three-level conduit 104 --- when this flowing occurs --- also with passing through the first one-level conduit 102
Current are at an acute angle.Therefore, in order to enter the first three-level conduit 104, the first one-level conduit 102 is flowed through to junction surface 105
Water must significantly change its route, as indicated by arrow 111.By comparison, the first two level conduit 103 is arranged to
The continuity of one one-level conduit 102 so that the water of the first two level conduit 103 is flowed into from the first one-level conduit 102 need not change it
Route.The inventors discovered that this relation between conduit is advantageous to reduce the amount of the water flowed into the second water sheath 108, especially
It is even more so when valve 110 is closed.
Secondly, the first three-level conduit 104 is connected to the bottom of the second water sheath 108.With the water in the second water sheath 108
Absorb the heat from piston-cylinder, most hot water will tend on move to the top of the second water sheath 108, that is, shown in Fig. 1
Schematic diagram top.Therefore, most hot water is left on connecting with the fluid with the first three-level conduit 104 for the second water sheath 108
Connect opposite end.This contributes to the thermal siphon for preventing the water from the second water sheath 108.This thermal siphon preferably makes
Piston-cylinder is probably undesirable in the case of rapidly initially warming up.
Once piston-cylinder has reached desired temperature, the can of valve 110 is opened to allow water to flow out the second water sheath
108.Just be pumped across some water in the colder water of the first one-level conduit 102 then will along the first three-level conduit 104 to
Under advance in the second water sheath 108, in the second water sheath 108, these water can absorb from piston-cylinder heat and
Therefore the temperature of regulating piston cylinder is helped.
However, when valve 110 is opened, due to sharp between the first three-level conduit 104 and the first one-level conduit 102
Angle, the water for flowing through the first two level conduit 103 will be less than by flowing through the water of the first three-level conduit 104.Therefore, compared to
The water being transported in the second water sheath 108, more cooling waters are transported to the first water sheath 106.Therefore, piston-cylinder damages
The heat of mistake is fewer than piston-cylinder lid, and piston-cylinder may remain in the temperature higher than piston-cylinder lid.Regulation can be passed through
It is accurate between two level conduit and the water of three-level conduit that three-level conduit controls pumping to pass through relative to the angle of one-level conduit
Relation.
In addition, the first three-level conduit 104 is also narrower than the first two level conduit 103, reason is that the first three-level conduit 104 has
The smaller hole of cross-sectional area.This has the effect of the further current that limitation enters in the second water sheath 108.Therefore, may be used also
To change the hole of three-level conduit by the hole relative to two level conduit to control pumping to pass through the first two level conduit 103 and the 1st
Relation between the water of level conduit 104.
