Description

A canister having a detachable auxiliary canister (CANISTER)

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a canister for a vehicle, and more particularly, to a canister having a detachable auxiliary canister capable of minimizing bleeding by ensuring that evaporative gas can be trapped in the canister.

Generally, the gasoline that is filled in the fuel tank is sent to the engine by the fuel pump, and the unused fuel is sent to the fuel tank again. The fuel sent back to the fuel tank is heated by the heat of the engine when the engine is driven. When the ambient temperature rises to a high temperature, such as during the summer, the temperature of the gasoline in the fuel tank further rises.

As described above, when the gasoline temperature rises in the fuel tank, harmful gas such as hydrocarbon (HC) is generated. The harmful gas thus generated is drawn out of the fuel tank by the pipeline connected to the fuel tank. The canister serves as a reservoir for collecting the harmful gas that escapes to the outside.

As described above, the canister sucks harmful evaporative gas generated in the fuel tank of the automobile by adsorbing it on the activated carbon provided in the canister when the engine is not operated. When the engine rises and RPM rises, the canister evaporates And a function of preventing the loss of fuel generated in the fuel tank by performing gas combustion by transferring the gas to the engine.

A conventional canister having the above-described functions is shown in FIG. 1, and a conventional canister will be described with reference to the drawings.

As shown in FIG. 1, a generally used canister 10 includes a housing 11 filled with activated carbon, an inlet 11 through which an evaporative gas as a noxious gas flows from a fuel tank to an upper portion of the housing 11 12, an outlet 13 through which the evaporation gas is discharged to the intake side of the engine during operation of the engine, and an evaporation gas adsorbed by the activated carbon 15 during engine off to the outside (Not shown).

Here, the housing 11 is divided into a main canister 10a for adsorbing and storing evaporative gas, and an auxiliary canister 10b for preventing evaporative gas not adsorbed on the main canister 10a from being discharged to the outside The main canister 10a and the auxiliary canister 10b are communicated with each other and the inlet 12 and the outlet 13 are formed in the main canister 10a and the air inlet 14, Can be formed in the auxiliary canister 10b.

That is, the conventional canister 10 collects most of the evaporated gas in the main canister 10a, collects some of the evaporated gas not captured in the main canister 10a, and at the same time, ) To the inside.

However, in the conventional canister 10, activated carbon is filled in the auxiliary canister 10b formed with the atmospheric inflow port 14 in order to improve the collection performance of the evaporated gas and minimize the discharge of the evaporated gas to the outside.

Accordingly, when the foreign matter is excessively collected in the activated carbon 15, the ventilation resistance is increased and the unevaporated gas in the main canister 10a passes through the auxiliary canister 10b as it is There is a drawback that bleed emission is generated in the atmosphere.

Accordingly, the present applicant has found a vehicle canister equipped with a detachable auxiliary canister for solving the above-mentioned problems.

SUMMARY OF THE INVENTION According to an embodiment of the present invention, there is provided a vehicular canister having a detachable auxiliary canister for minimizing bleed emission of evaporated gas into the atmosphere.
