Problems solved by technology

[0012] However, although the injection work of the urea injection gun 19 has stopped, when the urea injection gun 19 is removed from the filler neck 18, the pressurized pressure in the urea tank 10 is still applied, so a part has been pushed from the urea tank 10 to the booster. The urea of ​​the filler neck 18 overflows out of the filler neck 18
Further, the urea overflowing from the filler neck 18 crystallizes as white crystals, and the crystallized urea will stain the surface of the vehicle body

Abstract

The invention relates to a urea-filling device for diesel vehicles, which may include a urea-overflow-preventing space formed in a portion of a urea filler neck to temporarily accommodate urea flowingbackwards from a urea tank, easily preventing urea from overflowing out of the urea filler neck.

Description

technical field [0001] The invention relates to a urea filling device for diesel vehicles. More particularly, the present invention relates to a urea filling device for a diesel vehicle configured to easily prevent urea from overflowing the filler neck from the urea tank when the urea tank is filled with urea. Background technique [0002] Generally, an exhaust system of a diesel engine is provided with a selective catalytic reduction (SCR) system for injecting urea into an exhaust pipe to efficiently remove nitrogen oxides. [0003] Urea is decomposed by exhaust heat into a plurality of ammonia molecules, and the ammonia reacts with nitrogen oxides included in the exhaust, whereby harmless nitrogen and water are released to the outside as reaction products. [0004] Therefore, diesel vehicles (especially commercial vehicles) are provided with a urea tank filled with urea and a diesel fuel tank filled with diesel fuel. [0005] refer to figure 1 , The conventional urea fi...
