Description

BAFFLE FOR URAY TANK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baffle for urea water tanks, and more particularly, to a baffle for a urea water tank in which upper and lower ends of the baffle are combined with urea water tanks.

Generally, in a vehicle, exhaust gas is generated during engine operation, and in the case of a diesel engine, exhaust gas containing a large amount of nitrogen oxides (NOx) is discharged to the outside.

As the combustion temperature increases, the amount of nitrogen oxides (NOx) increases as the combustion temperature increases and serious air pollution occurs when the exhaust gas is discharged. Therefore, in order to reduce the amount of nitrogen oxides, the combustion temperature of the engine is controlled, So that a method of installing and cleaning is performed.

Urea-Selective Catalyst Reduction (UREA-SCR) is applied to purify nitrogen oxides emitted from a vehicle. This system uses various sensors such as nitrogen oxide sensor and urea water injection control system The number of urea is injected precisely, and the injected urea water is pyrolyzed by the exhaust gas heat and converted into ammonia.

Then, the ammonia reacts with the nitrogen oxide in the SCR catalyst to decompose into water and nitrogen, thereby reducing the nitrogen oxide in the exhaust gas.

The urea water used for reducing the nitrogen oxides in the exhaust gas is stored and stored in the urea water tank installed in the vehicle, and the urea water stored in the urea water tank generates flow noise due to inertia movement during running of the vehicle In order to reduce the flow noise of the urea water, a baffle is installed inside the urea water tank.

However, the conventional baffle for urea tanks is disadvantageous in that only the upper end or the lower end of the baffle is connected to the urea water tank and thus the baffle can not be firmly installed. Particularly, when urea water flows due to inertia The baffle is shaken together, and in the worst case, the baffle is detached from the urea water tank, so that it can not function as a baffle.

In addition, when only one end of the baffle is installed in combination with the urea water tank, there is a gap between the opposite end of the baffle that is not coupled with the urea water tank and the urea water tank. The effect of reducing flow noise is reduced.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
