Abstract

The invention relates to a fuel supplier of internal combustion engine driven by heavy oil, which comprises at least one high-pressure storage device, while the heated fuel via a valve and the high-pressure storage device is transmitted to each cylinder of the internal combustion engine. The high-pressure storage device is provided with an internal pressure body (1) for containing pressed fuel and a shell with a chamber (5) for surrounding the pressure body. The heat loss of the fuel in the pressure body (1) is reduced by at least part of the chamber (5) is supplied with fluid at the temperature some like as the temperature of injected fuel.

Description

Fuel oil supply device
Technical field
The present invention relates to a kind of fuel oil supply device that is used for the heavy oil internal combustion engine driven, this fuel oil supply device has at least one high pressure accumulator, fuel oil through heating flows to each cylinder of internal-combustion engine through valve from this high pressure accumulator, and wherein high pressure accumulator has a pressure body inside, that hold the fuel oil that is under pressure and a shell that surrounds this pressure body under the situation that forms a cavity.
Background technique
A kind of like this fuel oil supply device is described in EP1 314 883 A2.
Summary of the invention
Task of the present invention is, reduces the heat loss of the fuel oil in the pressure body.
This point realizes by following measure according to the present invention, promptly can supply with at least a portion of described cavity with a kind of fluid, and the temperature of this fluid is equivalent to the temperature of fuel oil to be sprayed at least approx.By this measure, avoided at least a outside transmission of heat of wall of passing pressure body.By using a kind of its temperature to surpass the fluid of the temperature of fuel oil, can improve the mobile performance of fuel oil.
According to an embodiment of the invention, in a fuel oil supply device, the both sides of wherein said pressure body are sealed by a cover plate respectively under the situation of inserting a sealing mechanism, in the inside of cavity another sealing mechanism being set to the less distance of each cover plate for sealing mechanism, sealing mechanism with a leakage of oil collecting chamber that is provided with a discharge conduit and described remaining, the cavity that is provided with described fluid separates.
Described fluid is preferably and is subjected to pressure, the process heating slightly fuel oil.Because after all will use fuel oil, so only need simple pipeline can realize the present invention.
According to another kind of form of implementation of the present invention,, a kind of special circulation mechanism is used for described fluid, for example oil or steam if being set.In this case, exist the extra possibility that heats of the fuel oil in the pressure body.
Description of drawings
Further feature and advantage are by additional dependent claims and drawing according to the description of the drawings for one embodiment of the invention.Accompanying drawing illustrates:
The skeleton diagram of a high pressure accumulator of Fig. 1; With
An end of this high pressure accumulator of Fig. 2.
Embodiment
The pressure body of the hose-shaped design of high pressure accumulator is with 1 expression in the accompanying drawings.Pressure body 1 is surrounded by a shell 4 that is similarly hose-shaped design, forms a cavity 5 like this between 1,4 member.The both sides of pressure body 1 are used 2,3 sealings of a cover plate, input and discharge that this cover plate 2,3 is used to be subjected to high pressure, passes through the fuel oil of heating respectively.
Cavity 5 seals with a sealing mechanism 7 that is designed to O-ring seals as shown in Figure 2.In an illustrated embodiment, in cavity 5 inside another sealing mechanism that is designed to O-ring seals equally 8 is set.This O-ring seals by a kind of heat-resisting, make for the stable elastomer of fuel oil.Sealing mechanism 7 and 8 is separated out a leakage of oil collecting chamber 9, and this leakage of oil collecting chamber not only outwards but also towards remaining cavity 5 had sealed.A discharge conduit 10 is passed in the leakage of oil collecting chamber 9.The other end at pressure body 1 is provided with same structure.
An input pipeline 11 and a discharge conduit 12 that will be used for a kind of fluid are passed into cavity 5, and the temperature of this fluid is equivalent to the temperature of the fuel oil that will spray at least approx.The simplest situation of this fluid can be through fuel oil heating, under pressure effect slightly.Fuel oil that comprised in pressure body 1, that be subjected to high pressure so, the process heating has been avoided cooling off to a great extent.
Yet a kind of temperature is higher than the fluid of the fuel oil temperature that will spray also can be input in the cavity 5.For this fluid (can be oil or steam) a kind of circulation that separates is set so.
If do not need leakage of oil is monitored, can remove sealing mechanism 8 so.
Embodiment shown in the present invention is not limited to, for example pressure body also can design longlyer, so only needs a pressure body to be used for supplying with fuel oil into all cylinders of internal-combustion engine.
