Structure shows oil sump for lubricant oil 220 or oil conservator 215 shown in figure 2.Oil conservator 215 can comprise the pregreasing pump 240 for lubricant oil 220.Pregreasing pump 240 can be connected to heat exchanger 25 via lubricating oil inlet 35.In this exemplary embodiments of the present invention, the coil pipe 210 for lubricant oil can be accommodated in heat exchanger 25.Coil pipe 210 for lubricant oil 220 can be connected to lubricating oil inlet 35 in the first side and can be connected to time grease feed pipe 40 at the second end of coil pipe 210.Coil pipe 210 Ke She Ge is in the chamber 235 be defined in heat exchanger 25.
Self Ke of heat exchanger 25 with Bei She Ge in the housing 24 of fuel filter 23.But, heat exchanger 25 also Ke Yi She Ge at the Ling mono-Wei Ge of heating system 10.In fuel filter 23, She Ge or a part of She Ge as fuel filter 23 can provide the advantage reducing system dimension.
As shown in Figure 2, the lubricant oil discharge tube 60 of each sparger 15 can extend in oil conservator 215, leaves the injector body 151(of sparger 15 thus see Fig. 3) lubricant oil turn back in oil conservator 215.

Fig. 3 shows and can be used in sectional arrangement drawing that is in the system shown in Fig. 1 or Fig. 2 and the typical embodiment of fuel injector 15 as described in this article.
The injector body 151 Ke Yi She Ge illustrated has grease channel 152,153 and 154.The modular design of passage 152,153 and 154 can be make being cooled via the lubricant oil 220 flowed along direction 155 or heating at least partially of sparger 15.Herein, passage 152 and 154 is straight, but in other exemplary embodiments, these passages can be designed to difference or have different shapes, and such as, as coil pipe, or passage 152,153 and 154 can be bending.Passage 153 is depicted as annular pass, and it surrounds moveable sparger needle-valve 157, but any design being applicable to provide the heat trnasfer of the part near passage 153 from the lubricant oil flow to passage 153 to sparger 15 also can with other.This point is also applicable to passage 152,154.
In this exemplary embodiments of fuel injector 15, ， She Ge has plural nozzle bore 158, can be injected in relevant firing chamber (not shown) via these nozzle bore 158 fuel.Time point and the amount of the fuel sprayed via nozzle bore 158 can be controlled by moveable needle-valve 157.
The entrance of the passage 152 of the upside of injector body 151 can be connected to relevant arm 55.The outlet of the passage 156 of the upside of injector body 151 can be connected to relevant discharge tube 60.
The viscosity of the fuel that Fig. 4 is dissimilar under showing drawn different temperatures and the chart of kinetic viscosity.Particularly, the different kinetic viscosity comparing polytype heavy fuel oil at different temperature with gas oil peculiar to vessel with marine diesel oil and different viscosities is delineated.In addition, the limit of preheating and the limit of pumpability is also delineated for different temperature.
Obviously, marine diesel oil does not need to be preheating to higher than 50 DEG C.But, dissimilar heavy fuel oil (IF700) though the temperature of viscosity more than 150 DEG C under also higher than MDO a lot.Therefore, if internal-combustion engine has been supplied to heavy fuel oil and the heavy fuel oil that burns, one such as referred in this in multiple heavy fuel oil, so, this heavy fuel oil must be preheated, because if the words of not preheating are restriked, oil viscosity can too high and HFO particularly can not flow in sparger in fuel feed pipe and in its assembly.This problem internal-combustion engine do not burn any fuel standby under outstanding especially.Therefore, known during standby heavy fuel oil be preheated and circulate in supplying pipe.
But during standby, the heavy fuel oil particularly remained in sparger may stagnate and temperature is reduced to the temperature of such as about 60 DEG C.As shown in Figure 4, at this temperature, oil viscosity of restriking is very high and may be difficult to restart internal-combustion engine.
According to the present invention, principal content can comprise: even if in the standby mode, uses by the lubricant oil that self heated by the circulating fuel (such as heavy fuel oil) heated to keep sparger warm.
Industrial applicability
Hereinafter, will the basic operation comprising the fuel injection system 10 of heating system 10 be described.
Under the operating mode of internal-combustion engine, the heavy fuel oil of the type that fuel is such as mentioned in the diagram, is fed into each sparger 15 via common rail 300 and arm 310.Appropriate fuel can be injected in relevant firing chamber at controlled time point via fuel injector 15.Here, common rail 300 is used to treating that the fuel sprayed via sparger 15 provides enough pressure.But, also can use the technology except Common-rail technology, such as, use and comprise the multiple high-pressure service pump Zhuan Ge separated being connected to multiple sparger.
During the operating mode of internal-combustion engine, lubricant oil 220 can be fed into each sparger 15 via main grease feed pipe 70 and common feed pipe 50 and arm 55.In the case, lubricant oil 220 can flow in injector body 151 along the direction indicated by reference mark 155 in passage 152,153 and 154, and leaves injector body 151 via respective discharge tube 60.
In the operating mode, lubricant oil 220 can cool each sparger 15, and lubricant oil 220 can have and has than supply the temperature that the temperature of each sparger 15 of high pressure (such as, 1500bar to 2000bar or even higher) fuel is low.Therefore, the temperature of sparger 15 can rise during operating mode, and must be reduced by the lubricant oil 220 circulated wherein.
If internal-combustion engine is switched to the standby of wherein burn in sparger 15 little fuel or not combustion fuel, so fuel particularly heavy fuel oil can be recycled to make whole motor remain in suitable temperature levels to avoid occurring any less desirable fuel solidifying in systems in which.Therefore, particularly Ke Yi She Ge heating plant (not shown) for the fuel heating direct circulation during standby.
Incidentally, when internal-combustion engine runs in the operating mode, due to the high pressure of lubricant oil 220 supplied by pump 250, safety check 65 can be opened, and due to the low pressure of the lubricant oil in pipeline 40, safety check 45 can cut out, thus makes the lubricant oil in time grease feed pipe 40 can not enter into common feed pipe 50.In addition, pump 240 can be closed in the operating mode.
During standby, can operate as follows according to system of the present invention.
Lubricant oil 220 can be pumped into heat exchanger 25 from oil conservator 215 by pump 240.Meanwhile, in fuel supply system 7, the fuel heated of circulation can be directed in heat exchanger 25, and can leave heat exchanger via outlet 30.The fuel heated can be circulated back in entrance 20 as shown in dashed line in figure 2.Because flow in the coil pipe 210 of lubricant oil 220 She Ge in heat exchanger 25, circulation in the heat exchanger 25 of the fuel simultaneously heated in chamber 235, so the temperature of lubricant oil in coil pipe 210 can be raised.The rising of this temperature controls by control unit, and this control unit can be connected to pump 240 and fuel feed pump 270.
Alternatively, the pumping rotational velocity of pump 240 and/or pump 270 can be adjusted, thus make the lubricant oil 220 leaving heat exchanger 25 can reach the temperature of expectation.
Another possibility can comprise the flow that the lubricant oil 220 mechanically controlling to have heated enters each sparger 15.According to another exemplary embodiments of the present invention, the flow entering the lubricant oil 220 heated of common feed pipe 50 can mechanically control, such as, via perforated plate.This perforated plate can be adjusted, thus penetration hole diameter can be adjusted.
The lubricant oil heated can leave heat exchanger 25 via secondary grease feed pipe 40, and can flow through each injector body 151 via passage 152,153 and 154.The lubricant oil leaving each sparger 15 can flow back into oil conservator 215 via discharge tube 60.Therefore, the temperature of sparger 15 can remain on predetermined temperature level, thus makes the solidification particularly can avoiding or at least can reduce fuel or residue etc. in the proposed system in sparger 15.
Although describe the preferred embodiments of the present invention herein, multiple improvement and amendment can be comprised when not departing from the scope of following claim.
