Abstract：In order to meet the market demand for single gas marine engines with the cylinder diameter less than 200 mm and the power greater than 600 kW,the Z6180 dual fuel engine is used as the parent engine,based on modular design ideas,the air system,gas system,and control system of the engine are designed.A single fuel marine liquefied natural gas(LNG)engine with a cylinder diameter of 180 mm is developed.According to the requirements of"Emission Limits and Measurement Methods for Marine Engine Exhaust Pollutants(China Phase Ⅱ)",a 2 000 h emission durability test is conducted on the engine.The test results show that the developed LNG engine meets the design requirements,the natural gas supply system and the precise gas control strategy for the engine under all operating conditions are durable and reliable,and the emission indicators meet the requirements of the National Standard II for ship engines.
