Obviously, marine diesel oil does not need to be preheating to higher than 50 ℃.Yet, dissimilar heavy fuel oil (IF700) though viscosity also more a lot of than MDO at the temperature more than 150 ℃.Therefore, if internal-combustion engine has been supplied to heavy fuel oil and burning heavy fuel oil, a kind of in multiple heavy fuel oil referred in this for example, so, this heavy fuel oil must be preheated, because if the words of not preheating are restriked oil viscosity can be too high and HFO can not particularly flow in sparger in fuel feed pipe and in its assembly.This problem is outstanding especially under internal-combustion engine does not burn the standby of any fuel.Therefore, be preheated and circulate in supplying pipe at heavy fuel oil during standby as can be known.
Yet, during standby, remain on particularly that heavy fuel oil in sparger may stagnate and temperature is reduced to for example temperature of about 60 ℃.As shown in Figure 4, at this temperature, the oil viscosity of restriking is very high and may be difficult to restart internal-combustion engine.
According to the present invention, the principle content can comprise: even under standby, use by the lubricant oil of self heated circulating fuel (for example heavy fuel oil) heating to keep sparger warm.
Industrial applicability
Hereinafter, explanation is comprised the basic operation of the fuel injection system 10 of heating system 10.
Under the operating mode of internal-combustion engine, the heavy fuel oil of the type that fuel is for example mentioned in Fig. 4 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, rail 300 is used to treating that the fuel via sparger 15 sprays provides enough pressure altogether.Yet, also can use the technology except common rail technology, for example, use to comprise a plurality of high-pressure service pump De Zhuan Ge that separate that are connected to a plurality of spargers.
During the operating mode of internal-combustion engine, lubricant oil 220 can be fed into each sparger 15 via main lubricant oil supplying pipe 70 and common feed pipe 50 and arm 55.In the case, lubricant oil 220 can flow in passage 152,153 and 154 in injector body 151 along the indicated direction of reference mark 155, and leaves injector body 151 via discharge tube 60 separately.
Under operating mode, lubricant oil 220 can cooling each sparger 15, and lubricant oil 220 can have the low temperature of temperature that each sparger 15 of high pressure (for example, 1500bar to 2000bar or even higher) fuel is arranged than supply.Therefore, the temperature of sparger 15 can rise during operating mode, and must reduce by the lubricant oil 220 of circulation therein.
If internal-combustion engine is switched to wherein in sparger 15 burning fuel or the standby of combustion fuel not seldom, so fuel particularly heavy fuel oil can be recycled so that whole motor remains in suitable temperature levels to avoid occurring any fuel solidifying of not expecting in system.Therefore, particularly Ke Yi She Ge heating plant (not shown) to be used for the fuel in the direct circulation of standby heating.
Incidentally, when internal-combustion engine moves under operating mode, high pressure due to the lubricant oil 220 of being supplied with by pump 250, safety check 65 can be opened, and the low pressure due to the lubricant oil in pipeline 40, safety check 45 can cut out, thereby makes the lubricant oil in time lubricant oil supplying pipe 40 can not enter into common feed pipe 50.In addition, can close pump 240 under operating mode.
During standby, can followingly operate according to system of the present invention.
As a kind of possibility, can adjust the pumping rotational velocity of pump 240 and/or pump 270, thereby make the lubricant oil 220 that leaves heat exchanger 25 can reach the temperature of expectation.
Another possibility can comprise that lubricant oil 220 that mechanically control has been heated enters the flow of each sparger 15.According to another exemplary embodiments of the present invention, the flow that enters the lubricant oil that has heated 220 of common feed pipe 50 can mechanically be controlled, for example, and via perforated plate.This perforated plate can be adjusted, thereby makes penetration hole diameter to be adjusted.
The lubricant oil that has heated can leave heat exchanger 25 via inferior lubricant oil supplying pipe 40, and can be via passage 152,153 and 154 each injector body 151 of flowing through.The lubricant oil that leaves 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, thereby makes the curing that particularly can avoid or can reduce at least fuel or residue etc. in the system that proposes in sparger 15.
Although this paper has illustrated the preferred embodiments of the present invention, can comprise multiple improvement and modification in the situation that do not depart from the scope of following claim.
