부품을 배치하기 위한 공간이 부족해지는 일 없이, 연소실 내에 요소수를 직접 분사한다. 선박용 디젤 엔진(1)은, 연소실(17)을 구획하는 실린더(16)와, 연소실(17)의 천장면을 구획하는 실린더 커버(15)에 배치되며 당해 연소실(17)을 개폐하는 배기 밸브(18)와, 실린더 커버(15)에 배치된 복수의 연료 분사 밸브(30)를 구비한다. 복수의 연료 분사 밸브(30)는, 실린더(16)의 둘레 방향을 따라, 배기 밸브(18)를 둘러싸도록 배치된다. 복수의 연료 분사 밸브(30)는 모두, 연료와 요소수를 층상 분사하도록 구성된다.

    The present invention relates to a marine diesel engine. According to the present invention, a urea water is directly sprayed into a combustion chamber without running out of a space for arranging components. The marine diesel engine (1) comprises: a cylinder (16) defining a combustion chamber (17); an exhaust valve (18) disposed on a cylinder cover (15) defining the ceiling surface of the combustion chamber (17) and opening and closing the combustion chamber (17); and a plurality of fuel spray valves (30) disposed on the cylinder cover (15). The plurality of fuel spray valves (30) are arranged to surround the exhaust valve (18) along the circumferential direction of the cylinder (16). All of the plurality of fuel spray valves (30) are configured to spray a fuel and the urea water in layers.
