Description

Canister installation structure of automobile fuel system

The present invention relates to a canister mounting structure of an automobile fuel device.

In general, the fuel device of a vehicle is a device that supplies the mixer necessary for the engine under the most operating conditions in the most combustible state and is an important device that greatly influences the performance of the engine, in particular, the power or economy.

The main part of the device is a carburetor or a fuel injector where the fuel and air are properly mixed and supplied to the engine. The fuel supplying device includes a fuel tank for storing fuel, a fuel filter for removing moisture and dust in the fuel, and a fuel pump for pumping fuel, which are connected to the fuel pipe. In recent years, in order to prevent the release of gasoline vapors into the atmosphere from the fuel system, a fuel evaporation gas emission suppression apparatus using a charcoal canister is installed.

Such canister refers to a pipe (charcoal canister) in which activated carbon is placed inside to prevent the car's engines from being stopped and being released into the atmosphere by capturing the fuel gas evaporated from the carburettor and fuel tank. When the engine is started, it is injected into the combustion chamber through the intake exhaust pipe by the control of the Purge Control Solenoid Valve (PCSV).

As shown in FIG. 3, the canister mounting structure of the vehicle fuel device includes an inlet port 2 through which the boil-off gas generated in the fuel tank is introduced, and an exhaust port 3 through which the boil-off gas and air are discharged to the engine. And a canister body (1) having an air inlet (4) through which air is introduced into the bottom surface, a joining bracket (5) protruding up and down on a predetermined portion of the main body side, and a fastener to which the canister body (1) is coupled It consists of (6).

The canister mounting structure of the conventional automobile fuel device configured as described above is formed such that one side of the fastener 6 to which the canister body 1 is coupled is opened, and the other side thereof forms a plurality of holes 7, and then the fastener 6 The fastener 6 is fixed to the vehicle body by tightly attaching the hole 7 of the c) to the vehicle body.

At this time, the fastener 6 is opened up and down and the upper side is wide and the lower side is formed to be narrow so that the size of the canister body 1 can be appropriately changed slightly.

Meanwhile, one side of the canister body 1 coupled to the upper side of the fastener 6 has a coupling bracket 5 having elasticity protruding upward and downward from one side of the canister body 1 so that the coupling bracket 5 is coupled to the fixture 6. ) Is tightly fixed in the fixture (6).

However, since the canister mounting structure is small in size, the canister mounting structure is light in weight, and thus, the canister mounting structure can be installed in combination with the fixture 6, but in recent years, it supports the regulation of enhanced evaporative and onboard refueling vapor recovery. In order to increase the capacity and size of the canister, the canister body 1 is too heavy to be installed and fixed to the vehicle body with the existing fixture 6, so that the fixture 6 is too heavy. It will not support the weight of the body

As described above, the canister mounting structure of the vehicle fuel device can be installed on the vehicle body by the fixture when the weight of the canister body is light. However, when the canister body becomes large and opposing, the weight of the canister body does not support the weight of the canister. Not only that, there is a problem that can not be installed using the fixture because the canister body is not coupled to the fixture because the size does not fit.

Therefore, an object of the present invention is to form a tray on which the canister body of the automobile fuel device is seated, and a fixing clip for fixing the canister body seated on the tray to the tray, so that the canister body is more stably and firmly fixed to the vehicle body. To provide a canister installation structure for an automobile fuel system.

The canister installation structure of the automobile fuel device of the present invention for achieving the above object is the canister body (1) and the inlet port (2) and the exhaust port (3) is formed on the upper surface and the air inlet (4) is formed on the bottom surface; A coupling bracket 5 protruding up and down on a predetermined portion of the side of the canister body 1 and a fixture 6 to which the canister body 1 is coupled, the inlet 11 and the exhaust port 12 on the upper surface thereof. And a canister body 10 in which an air inlet 13 is formed; A tray 14 on which the canister main body 10 is seated and on which both sides of the canister bracket 16 are welded and fixed; The canister body 10 and the tray 14 is characterized in that it consists of a fixing clip 18 for fixing in close contact with each other.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is an exploded perspective view of the present invention, showing a state in which the canister body 10 is separated from the tray 14.

As shown in the drawing, it is preferable to form a plurality of through holes 17 on the bottom surface of the tray 14 on which the canister body 10 is seated so that water flowing into the tray 14 does not accumulate on the bottom surface of the tray 14. Do.

2 is a cross-sectional view of the coupling state of the present invention.

As shown, the fixing clip 18 coupled to the upper surface of the canister body 10 seated on the tray 14 and the tray 14 side bracket 15 forms an elastic coupling portion 19 at both ends. do.

The elastic coupling portion 19 is coupled to the coupling hole 16 of the bracket 15 when coupled to the tray 14 side bracket 15.

The inlet 11, the exhaust 12, and the air inlet 13 formed on the upper surface of the canister body 10 are provided at predetermined intervals from each other.

Referring to the operation of the present invention as described above are as follows.

After the canister body 10 is seated on the tray 14, the fixing clip 18 is elastically coupled to the upper surface of the canister body 10 and the bracket 15 on the side of the tray 14. At this time, the coupling hole 16 is formed in the bracket 15 on both sides of the tray 14, and the elastic coupling part 19 formed at the end of the fixing clip 18 in the coupling hole 16 is elastically coupled.

As described above, the canister body 10 seated on the tray 14 and fixed to the fixing clip 18 can be easily installed due to the large size of the canister itself and its heavy weight.

The canister installation structure of the automobile fuel device of the present invention as described above is prevented from flowing in the canister body as the canister body is firmly fixed and supported by the tray and the fixing clip even if the canister body is enlarged in size and heavy in weight. At the same time, the size of the canister body is not restricted.

In addition, there is an effect such that the assemblability for installing the canister body is improved, and the productability and productivity are improved.
