A urea post-treatment system having an outside filler neck comprises: a urea filler neck (1) where a shut-off of an injecting gun (100-1), which is built in a filler housing (3) from which urea is discharged to a urea tank body making a urea storage space and is inserted into the entrance of a filler housing (3), is conducted by an increase in the pressure inside the filler housing by an overflowing urea (U) while urea is being injected, and which delays an overflow, where overflowing urea (U) goes out through the entrance of the filler housing (3), by storing the overflowing urea (U) in the internal space of the filler housing (3); and a urea tank (30) connected to the urea filler neck (1) with a urea injecting pipe (10) and a leveling pipe (20). The urea post-treatment system of the present invention can reduce the injecting gun shut-off response time in the late stage of the injection of urea and prevent an overflow of the urea. In particular, the urea post-treatment system of the present invention can allow the user to conveniently inject urea like injecting fuel through a fuel injecting hole since an outside-type layout for taking out the urea filler neck to the outside of a vehicle is applied.

    본 발명의 실외형 필러넥을 갖춘 요소수 후처리 시스템에는 요소수가 요소수 저장공간을 이루는 요소수 탱크 바디로 배출되는 필러 하우징(3)에 내장되고, 요소수 주입중 역류된 역류 요소수(U)에 의한 필러 하우징 내부의 압력상승으로 필러 하우징(3)의 입구로 삽입된 주입건(100-1)의 셧-오프(Shut-Off)가 이루어지며, 역류 요소수(U)를 필러 하우징(3)의 내부 공간에 저장해 역류 요소수(U)가 필러 하우징(3)의 입구로 나가는 오버플로우(Overflow)를 지연하는 요소수 필러 넥(1); 상기 요소수 필러 넥(1)에 요소수 주입 파이프(10)와 레벨링 파이프(20)로 연결된 요소수 탱크(30);가 포함됨으로써 요소수 주입 말기 시 주입건 셧오프 반응 시간의 단축과 요소수 오버플로우(Overflow)의 방지가 가능하고, 특히 요소수 필러 넥을 차량 외부로 빼내준 실외형 레이아웃이 적용됨으로써 연료 주입구를 통한 연료 주입과 같이 편리한 요소수 주입이 가능한 특징을 갖는다.
