선박에는 일반 연료(C중유) 탱크(3)와 저유황 연료(A중유) 탱크(4)가 탑재되어 있다. 또한, 엔진(1)의 배기계에는 요소수 분무 방식의 SCR 촉매(10)가 배치되어 있음과 아울러 배기 가스가 SCR 촉매(10)를 거치지 않고 통과하는 바이패스 배기관(16)이 배치되어 있다. 자선 위치 자동 검출 수단(B)과 규제 맵을 조합해서 규제 대상 해역까지의 거리가 자동적으로 연산되고, 규제 대상 해역으로의 도달에 맞추어서 연료를 자동적으로 일반 연료로부터 저유황 연료로 스위칭함과 아울러 배기 가스는 바이패스 배기관(16)에 흘려서 SCR 촉매(10)의 기능은 정지시킨다. 배기 가스 정화 상태의 스위칭이 자동적으로 행해진다.

    An exhaust gas purifying system of an engine (1) in a marine vessel comprising: an engine (1); a water generating machine (21) for changing a sea water to a real water; a water tank (22) for reserving the real water produced by the water generating machine (21); the engine (1), the water generating machine (21), and the water tank (22) being loaded in the marine vessel; an NOx included in an exhaust gas of the engine being purified by spraying (15) a reducing agent water solution to a reducing catalyst (10) provided in an exhaust pipe (8) of the engine; and the reducing agent water solution being manufactured by mixing a raw material reducing agent in solid-state, such as a powder state or a granular state, with the real water, wherein the exhaust gas purifying system has a raw material hopper (24) in which the raw material reducing agent is thrown, and a mixing tank (25) with agitating means (38) for mixing the raw material reducing agent discharged from the raw material hopper (24) with the real water so as to form a water solution, the water tank (22) and the mixing tank (25) are connected by a raw water conduit line (27), and a water solution conduit line (29, 31) leading the reducing agent water solution to the reducing catalyst (10) is connected to the mixing tank (25).
