Abstract
The utility model discloses an improved structure for an automobile built-in fuel oil pump consisting of a built-in fuel oil pump body and an outer box, wherein the outer box comprises an oil tank and an oil cap ring covered on the oil tank, the built-in fuel oil pump body is installed in the oil tank, and the oil cap ring contacts with and is sealed on the surface of the built-in fuel oil pump body. According to the improved structure for an automobile built-in oil fuel pump, the technical problem that the fuel oil consumption is unable to measure when the built-in fuel oil pump is connected with a test bench is solved, and the built-in fuel oil pump is capable of adapting to different engine fuel.
Description
Technical field
The utility model relates to a kind of automotive internal fuel pump, relates in particular to a kind of structure-improved of automotive internal fuel pump.
Background technique
Automobile fuel pump mostly is built-in fuel pump, and namely fuel pump is placed in the automotive oil tank.For engine rig test, if use the automotive internal fuel pump, oil pump and fuel tank are connected in the test-bed together, then can't measure fuel consumption.And the multiplex external fuel pump of engine rig test, the most cost of this fuel pump is higher, and for some specific fuel (such as methyl alcohol, ethanol etc.) motor, most external fuel pumps do not have corrosion resistance, thereby can not be general.
Application number is that 200820072913.4 Chinese patent discloses the interchangeable fuel oil pump assembly of a kind of built-in secondary filter, and the strainer in the fuel pump is that joint and clinging type is connected with secondary filter, and the pump core is enclosed in the secondary filter; Secondary filter is that joint and clinging type is connected with oil-storing barrel; Oil outlet tube has also adopted clamp connection structure with being connected of secondary filter; Secondary filter is connected the employing guide bar and connects with Oil pump flange, its plastic guides and secondary filter are clamp connection structure.But being connected in the test-bed, this built-in fuel pump still can't measure fuel consumption.
Summary of the invention
The utility model mainly provides a kind of structure-improved of automotive internal fuel pump, can solve built-in fuel pump and be connected to the technical problem that still can't measure fuel consumption in the test-bed, and can adapt to different motor fuels.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises built-in fuel pump body and outer container, described outer container comprises oil tank and the oil cap ring that covers on described oil tank, built-in fuel pump body is arranged in the described oil tank, and described oil cap ring contacts sealing with built-in fuel pump body surface.The utility model increases separately an outer case structure in built-in fuel pump body outside, removes original fuel tank, so that the utility model can receive on the threst stand, and does not affect fuel consumption.
As preferably, described oil tank is provided with the oil tank oil inlet hole.
As preferably, be provided with vent on the described built-in fuel pump body.The purpose of vent is to get rid of issuable gas in the oil tank.
As preferably, described built-in fuel pump body top is provided with oil outlet, return opening and power interface, and described oil outlet, return opening and power interface stretch out described oil cap ring.
As preferably, described built-in fuel pump body bottom is provided with the oil pump filler opening.
As preferably, be provided with the sealed silicon glue-line between described oil cap ring and the described built-in fuel pump body.By the sealed silicon glue-line is set, can prevent that fuel oil from leaking out from the slit of oil cap ring and built-in fuel pump body.
As preferably, described oil tank and described oil cap ring are threaded.
The beneficial effect that the utility model brings is:
1, oil mass is less in the oil tank, and vent hole is arranged, and does not affect the measurement of fuel consumption;
2, use the fuel pump of automobile design itself, go for all fuel, comprise specific fuel (such as methyl alcohol, ethanol);
3, easy to carry, can carry producer of outer committee and test;
4, with low cost.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of perspective view of oil cap ring of the present utility model and oil tank.
Label declaration: 1, oil cap ring; 2, oil tank; 3, oil tank oil inlet hole; 4, built-in fuel pump body; 4-1, oil outlet; 4-2, return opening; 4-3, power interface; 4-4, oil pump filler opening.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the structure-improved of a kind of automotive internal fuel pump of present embodiment as shown in Figure 1, 2, comprise built-in fuel pump body 4 and outer container, oil outlet 4-1, return opening 4-2 and power interface 4-3 are equipped with in built-in fuel pump body 4 tops, and built-in fuel pump body 4 bottoms are shaped with oil pump filler opening 4-4.
Outer container comprises oil tank 2 and the oil cap ring 1 that covers on oil tank 2, and oil tank 2 and oil cap ring 1 are threaded, and built-in fuel pump body 4 is arranged in the oil tank 2, oil cap ring 1 and built-in fuel pump body 4 Surface Contacts sealing.
Suck the fuel oil in the oil tank 2 during operation of oil pump, the oil outlet 4-1 by oil pump supplies to engine oil rail.Return opening 4-2 on the oil pump receives in the oil return pipeline of engine, carries stable-pressure device on the oil pump, like this, can realize that oil pump continues the stable fuel oil of supply pressure to motor.
Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is restriction to the utility model protection domain.The utility model not only is confined to above embodiment, and its concrete structure or shape allow to change.In a word, protection domain of the present utility model should comprise the apparent conversion of those corresponding those of ordinary skills or substitute and remodeling.
